Executive Summary

~2.1 million U.S. aerospace & defense jobs supported (direct and indirect, AIA/S&P Global estimate based on 2025 industry data)

~15% Industry-wide attrition in 2024, more than double the cross-industry average (AIA/McKinsey 2025 member survey)

70,000+ Unfilled security-cleared positions across the defense sector (AIA/PwC 2023, from June 2022 data; may be higher today)

As of late 2026, the U.S. aerospace and defense workforce is operating under a convergence of structural pressures. Employment remains substantial, with approximately 2.1 million jobs supported across direct and indirect roles in 2025. The industry generated $1 trillion in total business activity and contributed $500 billion in economic value, roughly 1.6% of U.S. GDP. Exports reached $172.7 billion, a 25% increase year over year. But workforce availability has become the binding constraint on whether that growth can be sustained.

The scale of the talent challenge is severe. According to the 2025 AIA/McKinsey workforce study, a survey of more than 30 A&D organizations representing over 600,000 U.S. employees, industry-wide attrition held steady at nearly 15% in 2024, which AIA and McKinsey characterize as more than double the average across other U.S. industries. Critical talent shortages in engineering and skilled trades are now among the largest constraints on industry expansion and innovation. BLS projections for 2025 to 2035 show about 177,500 openings per year for assemblers and fabricators economy-wide, almost all of them created by workers leaving or retiring rather than by new growth, with welders and cutters facing roughly 40,300 per year. These figures span all industries, and BLS does not break out the A&D-specific share separately. However, the concentration of assembler and welder occupations within aerospace manufacturing means the sector absorbs a disproportionate share of the pressure relative to its size, and the AIA/McKinsey study identifies these occupation groups as among the most critically constrained within A&D specifically.

Defense funding is adding to the pressure, mainly through the 2025 reconciliation law and the FY2027 request. The Pentagon’s FY2026 request totaled $961.6 billion, counting $113.3 billion of mandatory funding from the 2025 reconciliation law, with significant allocations for munitions production, missile defense, shipbuilding, and hypersonic weapons. Congress enacted $839.2 billion in regular FY2026 defense appropriations in February 2026, roughly level with FY2025, on top of the $152.3 billion the reconciliation law provided for defense through FY2029. In April 2026, the White House proposed a FY2027 defense budget of $1.5 trillion ($1.15 trillion in base funding plus $350 billion expected from a reconciliation bill), more than 40% above the prior year, amid the war with Iran. If enacted at or near that level, it would be the largest increase in U.S. military spending since World War II in inflation-adjusted dollars (PolitiFact notes the Korean War and World War II buildups were larger in percentage terms), and it would create significant new demand for workers the sector does not currently have. Congress has not enacted it: FY2027 began under a continuing resolution that runs through December 11, 2026.

At the same time, structural workforce constraints are intensifying. Nearly a quarter of A&D manufacturing and engineering employees are 55 or older, according to the 2025 AIA/McKinsey study, so retirements will keep draining experienced talent for years. More than 70,000 security-cleared positions were unfilled across the defense sector in June 2022 data that AIA/PwC published in 2023, and that figure may have grown as defense funding has risen since. Unlike other industries where labor shortages can be addressed through immigration, wage increases, or accelerated training, defense cleared roles face a unique bottleneck: the clearance pipeline is controlled by a government agency with its own capacity limits, and ITAR requirements restrict who can even be considered for many positions.

Into 2027 and beyond, workforce challenges in aerospace and defense are unlikely to resolve through spending alone. Firms that align workforce planning with compensation strategy, clearance pipeline management, skills development, and staffing flexibility will be better positioned to deliver against program commitments amid elevated demand.

1. Overview of the U.S. Aerospace & Defense Workforce

~930,000 Jobs at end-use A&D companies (AIA/S&P Global, 2025 data)

The U.S. aerospace and defense industry supported more than 2.1 million jobs in 2025, encompassing both direct employment and the extensive supply chain that supports it. AIA revised its estimates for earlier years with this edition, so growth rates calculated against figures from prior editions are not reliable; the BLS series below gives a consistent read on recent growth.

Of the total, approximately 930,000 jobs are at end-use companies, the primes and other firms that deliver finished aircraft, systems, and services. Commercial aerospace accounts for 51% of direct manufacturing employment and defense and national security for 49%. The industry is organized across four major subsectors: Aeronautics and Aircraft leads with roughly 434,000 workers, followed by Space at approximately 192,000, Land and Sea Systems at 170,000, and Cyber at 117,000. Supply chain companies account for about 1.1 million jobs, more than half of all A&D-supported employment, across an extensive network of thousands of small and medium-sized businesses that produce components, subsystems, and services critical to the sector’s output.

From an economic perspective, the industry generated $1 trillion in total business activity in 2025 ($988.6 billion in total sales), comprising $506 billion in direct output and nearly $483 billion in supply chain activity. The sector contributed $500 billion in economic value, accounting for 1.6% of U.S. GDP. Taken together, AIA’s 2025 figures work out to roughly four jobs for every $1 million of direct output, a multiplier effect that underscores why workforce constraints in A&D ripple far beyond the primes.

The industry also holds a distinction among U.S. manufacturing sectors: it posts the largest positive trade balance of any of them. U.S. A&D exports reached $172.7 billion in 2025, up 25% from the prior year, producing a $109.2 billion trade surplus. This export strength is directly tied to the skill level and productivity of the workforce, a competitive advantage that erodes if talent gaps widen.

For the purposes of this report, federal labor market data from the Bureau of Labor Statistics generally covers NAICS 336400 (Aerospace Product and Parts Manufacturing), which captures the manufacturing segment of the broader A&D industry. Industry-level employment, revenue, and workforce composition data come from AIA’s annual Facts & Figures report, compiled with S&P Global Market Intelligence, which encompasses the full scope of the sector including services, R&D, IT, and cybersecurity roles outside the manufacturing NAICS code.

The BLS data show the manufacturing core of the industry growing quickly. Employment in aerospace product and parts manufacturing reached 596,500 in August 2026 (seasonally adjusted, preliminary), up 27,800 jobs or 4.9% from August 2025. All of U.S. manufacturing added roughly 28,000 jobs on net over the same twelve months, so aerospace accounted for nearly all of the sector’s net job growth. Average hourly earnings for all employees in the industry reached $58.43, up 3.4% year over year.

2. Hiring Pressure and Vacancy Rates

~15% Industry-wide attrition rate (AIA/McKinsey 2025 member survey)

Despite consistent investment in workforce attraction and retention, the aerospace and defense industry continues to lose talent at a rate that threatens operational continuity. The 2025 AIA/McKinsey workforce study, drawing on data from more than 30 A&D organizations representing over 600,000 U.S. employees, found that attrition held steady at nearly 15% in 2024. The study’s authors characterize this as more than double the average turnover rate across other U.S. industries, and it persists despite years of focused effort to improve retention.

The problem is not that the industry struggles to attract workers. AIA/PwC’s 2024 workforce study found that labor market perceptions of the A&D industry are strong: 72% of employed individuals surveyed agreed that the industry’s values, purpose, and mission align with their own, a figure that rises to 81% among those already working within the sector. The challenge is retention. Workers join, but they don’t stay. AIA/PwC identified a core insight: the industry’s biggest workforce problem is creating experiences that are compelling enough to keep employees once they’ve accepted an offer. (For practical retention tactics, see How to Attract and Retain Aerospace Engineers.)

The talent gaps are concentrated in the roles most critical to production. BLS projections for 2025 to 2035 show about 177,500 openings per year for assemblers and fabricators economy-wide, nearly all of them from workers leaving or retiring (employment in the occupation is projected to grow just 1% over the decade), while welders, cutters, solderers, and brazers face roughly 40,300 openings per year. These figures span all industries, but the AIA/McKinsey study identifies these occupation groups as among the most critically constrained within A&D specifically. These are not roles that can be backfilled quickly; they require hands-on skill, often certification, and in many cases security clearance. Boeing’s 2026 outlook projects that North America alone will need 125,000 new maintenance technicians through 2045.

The hiring pressure is not felt equally across the supply chain. While primes like Boeing, Lockheed Martin, and Northrop Grumman can draw on brand recognition, mission appeal, and compensation scale to attract candidates, the thousands of small and medium-sized suppliers that account for more than half of A&D employment often cannot. A 50-person machine shop losing a handful of cleared machinists may not make headlines, but it can halt a program worth orders of magnitude more. The fragility at the lower tiers of the supply chain is where workforce constraints translate most directly into delivery risk.

The severity of hiring pressure varies by role and clearance requirement. Non-cleared production and trades roles compete with construction, data center, and energy sectors for the same labor pool. Cleared engineering and technical roles face a fundamentally different constraint (the clearance pipeline itself) which is addressed in detail in Section 4 of this report. In both cases, the result is the same: firms cannot hire fast enough to keep pace with demand, and the workers they do hire are expensive to recruit and difficult to retain.

3. Labor Supply Constraints

Nearly 1 in 4 A&D manufacturing and engineering employees are 55 or older (AIA/McKinsey 2025, based on BLS data)

Behind the attrition numbers is a deeper structural problem: the supply of available aerospace and defense workers is shrinking, and the forces driving that contraction are not easily reversed.

The demographic picture is the most urgent pressure. Nearly a quarter of A&D manufacturing and engineering employees are 55 or older, according to the 2025 AIA/McKinsey study, which draws on BLS data; AIA/PwC’s 2023 study had put the share of the workforce over 55 at more than 29%. Deloitte’s 2025 outlook noted that 25% of the workforce has more than 20 years of experience and is at or beyond eligible retirement age. Each of those retirements takes with it years of institutional knowledge in precision manufacturing, program management, certification, and classified operations. These demographic figures predate the 2025 reconciliation funding and the FY2027 budget request, and the underlying trend may have continued or intensified since.

The replacement pipeline cannot keep pace. Aerospace engineering requires at minimum a bachelor’s degree. Skilled trades roles (machinists, assemblers, welders, quality inspectors) require years of apprenticeship or technical training. And for defense roles, clearance processing adds months or years on top of the standard hiring timeline. The gap between when a worker enters the pipeline and when they are productive on a classified program can stretch to two years or more.

Competition from adjacent industries is intensifying, as commercial technology companies, data center construction, and commercial space startups recruit from the same engineering and skilled-trades pool, often with faster career progression and fewer compliance constraints. In Aerospace America, McKinsey associate partner Andy Voelker noted that entry-level engineers “want quicker, faster, more meaningful impact” and “come in and out of organizations at a much faster rate.” This generational shift in work expectations is colliding with an industry that has historically relied on long tenure and gradual advancement.

The semiconductor manufacturing sector is also pulling from the same engineering and skilled-trades pipeline, with CHIPS Act-funded fab projects projected to create roughly 115,000 new industry jobs by 2030, tens of thousands of which are at risk of going unfilled. See Amtec’s Semiconductor Workforce Report for more.

The competitive pressure has intensified further. In February 2026, SpaceX completed its merger with xAI at a combined valuation of $1.25 trillion. In June 2026 it went public on Nasdaq at $135 a share, raising about $75 billion at a $1.77 trillion valuation, the largest IPO on record. SpaceX flew a record 165 orbital launches in 2025 and reported roughly $19 billion in revenue for the year. The offering put about $75 billion of new capital into a company that is hiring across engineering, manufacturing, launch operations, and Starlink infrastructure, in direct competition with defense primes for the same talent pool. For mid-career engineers and cleared professionals weighing their options, a publicly traded SpaceX can offer liquid equity alongside a mission-driven culture, a package traditional defense contractors cannot easily match.

The defense-tech startup ecosystem is adding a parallel layer of competition. Venture investment in defense technology reached a record $49.1 billion in 2025, up from $27.2 billion in 2024, according to PitchBook data that include dual-use companies. By CB Insights’ narrower count, defense-tech startups raised $17.9 billion, more than double the prior year. Companies like Anduril Industries, which is building a Mississippi facility that aims to produce 6,000 tactical rocket motors annually, are recruiting aggressively from the same cleared engineering and manufacturing talent base that primes depend on, often offering equity packages that established contractors cannot replicate.

The AIA/PwC 2024 study identified a cultural divide that compounds the supply problem: nearly half of A&D employees expressed concerns about inadequate tools and technologies, and employees reported they do not feel empowered to drive change. The divergence in experience between salaried and hourly workers in onboarding, development, scheduling, and advancement is at the heart of what PwC describes as a cultural divide within organizations. Workers who don’t see a path forward are more likely to leave, contributing to the industry’s persistently high attrition.

4. Security Clearance & ITAR Workforce Constraints

70,000+ Unfilled security-cleared positions across the U.S. defense sector (AIA/PwC 2023 estimate)

No other industry faces a workforce constraint quite like this one. Aerospace and defense companies cannot simply find and hire qualified workers. For a significant share of roles, workers must also hold active security clearances granted by the U.S. government, and positions involving ITAR-controlled technology require U.S. Person status. These requirements create a structural bottleneck that wage increases, training programs, and recruiting campaigns cannot solve on their own.

The AIA/PwC 2023 workforce study reported more than 70,000 unfilled cleared roles across the defense sector, based on ClearanceJobs data from June 2022. Defense funding has risen since, mainly through the 2025 reconciliation law, so that figure may have increased. The study also cited a ClearanceJobs estimate that firms lose an average of $20,640 per month for each cleared role left unfilled. It is an industry estimate rather than an observed measurement, but it illustrates the revenue impact of clearance-constrained vacancies.

The clearance pipeline itself, while improving, remains a significant constraint. The Defense Counterintelligence and Security Agency (DCSA), which provides vetting services for 95% of the federal government and handled approximately 2.6 million investigative actions in FY2025, reported that its inventory of pending background investigations dropped to approximately 100,000 cases in January 2026, an all-time low and down 65% from the start of 2025. This represents meaningful progress, as the inventory had climbed to just under 300,000 cases by the end of fiscal 2024, the highest since late 2019.

However, processing timelines remain long. DCSA data presented to industry for Q3 FY2026 put the average end-to-end time for an initial Top Secret clearance at 243 days (20 days to initiate, 97 to investigate, and 126 to adjudicate) and for a Secret clearance at 197 days, with adjudication now the slowest step at both levels. DCSA now reports the average of all cases rather than the fastest 90%, so these figures are not directly comparable with older published timelines. Industry guides give wider ranges: four to eight months for Secret and eight to eighteen months for Top Secret, with TS/SCI adding further time for indoctrination and potentially a polygraph. ClearedJobs.Net puts 90th-percentile completion times at about four months for Tier 3 investigations and nine months for Tier 5.

DCSA has made strides in modernization. By spring 2025, about 75% of interviews were conducted virtually, up from 50% a year earlier. FBI name-check backlogs dropped from 42,000 to 20,000 cases after the FBI introduced a new prioritization tool in late 2024. And over 3.8 million cleared personnel are now enrolled in continuous vetting, replacing the old model of periodic reinvestigations every five to fifteen years.

But progress is fragile. The 2025 government shutdown paused fingerprint submissions to the FBI and halted or degraded facility clearance processing and industry background investigations. DCSA warned that when operations resumed, the throughput backlog would re-inflate as queued cases compounded. As one industry representative told Federal News Network: “When we turn it back on, that’s when you get the backlogs, because your throughput gets jammed up, and then everybody just keeps racking up behind you.” FY2027 began without a lapse, but the current continuing resolution expires December 11, 2026, so the risk of another interruption has been deferred rather than removed.

ITAR adds a separate constraint. Positions involving International Traffic in Arms Regulations-controlled technology require U.S. Person status, defined as a U.S. citizen, lawful permanent resident, or protected individual. This narrows the eligible labor pool significantly and cannot be addressed through immigration programs or offshore hiring. For defense contractors, ITAR compliance is not optional; it is a condition of doing business. (For more information, see the ITAR regulations from the Directorate of Defense Trade Controls and the EAR regulations from the Bureau of Industry and Security.)

The strategic implication is clear: unlike other industries where labor shortages can be partially addressed through higher wages, expanded recruiting, or training pipeline acceleration, the defense cleared workforce faces a bottleneck controlled by the federal government. Firms cannot hire their way out of a clearance backlog. The ones that manage clearance pipelines proactively, sponsoring clearances ahead of program awards and maintaining cleared talent pools, are better positioned to capture revenue when programs ramp.

5. A&D Workforce Pay Benchmarks

$127,000+ Average A&D wage (about 40% above the national average)

Compensation in aerospace and defense reflects the sector’s reliance on highly skilled, often security-cleared workers whose expertise commands a substantial premium over the broader economy.

According to AIA/S&P Global’s 2026 Facts & Figures, average A&D wages exceeded $127,000 in 2025, approximately 40% above the national average, and the industry generated $266 billion in labor income. These figures encompass both salaried and hourly workers across the full spectrum of direct and supply chain roles.

BLS occupational data provides more granular wage benchmarks for roles common across the A&D workforce. May 2025 estimates from the Occupational Employment and Wage Statistics program and the Occupational Outlook Handbook show the range:

• Aerospace engineers: $134,960/year median ($64.89/hour). The lowest 10% earned less than $86,700; the highest 10% earned more than $205,890.
• Aerospace engineering and operations technicians: $82,890/year median. The lowest 10% earned less than $59,050; the highest 10% earned more than $125,160.
• Aircraft structure, surfaces, rigging, and systems assemblers: $65,380/year median (May 2025). Wages vary by specialization and employer, with A&D assembly roles concentrated in NAICS 336400.

BLS occupational wage estimates reflect May 2025 data, the most recent available at the time of compilation. Given the reconciliation-funded increase in FY2026 defense spending and the proposed FY2027 budget, current market rates for in-demand roles, particularly cleared engineers and skilled trades, are likely above these published benchmarks. BLS monthly data point the same way: average hourly earnings in aerospace product and parts manufacturing rose 3.4% in the year to August 2026. For a wider view of production and trades pay, see Amtec’s Manufacturing Wage Report.

Wage pressure in A&D is increasingly role-specific rather than uniform. The most acute premiums are commanded by workers whose skills sit at the intersection of technical expertise and clearance eligibility, such as security-cleared systems engineers, cybersecurity specialists, program managers, and cleared machinists. For these roles, the scarcity of qualified and cleared candidates drives compensation well above occupational medians.

In the AIA/McKinsey 2025 study, 80% of companies named compensation and benefits as the primary driver of attrition. In a market where attrition runs near 15% and cleared workers can move between defense contractors with relative ease, firms that don’t meet or exceed market rates on pay lose workers to competitors, or to commercial tech and adjacent sectors that offer comparable or higher compensation without the compliance burden.

---

6. Total Compensation and Benefits

Wages alone do not reflect the true cost of employing A&D workers, or the full value proposition available to attract and retain them.

BLS Employer Costs for Employee Compensation (ECEC) data for private manufacturing (the closest available proxy; ECEC does not publish a standalone series for NAICS 336400) show total compensation costs of $48.62 per hour worked in June 2026, of which $16.12, or 33.1%, went to benefits. For comparison, benefits made up 30.5% of compensation costs in construction.

Benefits access among A&D workers is broad. The nature of the industry, with its concentration of large prime contractors and established supply chain firms, means that employer-sponsored health care, retirement plans, and paid leave are widely available. However, participation rates, particularly in retirement plans, often lag access rates, a pattern consistent with the broader manufacturing workforce.

The compensation picture in A&D is complicated by the salaried/hourly divide. The AIA/PwC 2024 study identified a significant divergence in experience between salaried employees (engineers, program managers, analysts) and hourly production workers (assemblers, machinists, technicians). This divergence extends to onboarding, career development, scheduling flexibility, and tool access. For hourly workers (the same production workforce driving the steepest attrition), the gap between their experience and that of their salaried colleagues is a contributing factor in retention challenges.

For A&D firms, competing on base pay alone while offering an uneven employment experience across worker categories leaves them exposed to employers in commercial tech, energy, and construction who may present a more complete total compensation proposition.

---

7. Workforce Stability and Union Representation

Union representation in aerospace and defense manufacturing reflects a mixed landscape shaped by history, geography, and the sector’s evolving workforce composition.

Major unions active in A&D include the International Association of Machinists and Aerospace Workers (IAM), the United Auto Workers (UAW), and the Society of Professional Engineering Employees in Aerospace (SPEEA). BLS Current Population Survey data show that 7.4% of durable goods manufacturing workers were union members in 2025 and 8.2% were covered by a union contract, close to the 7.7% membership rate for manufacturing overall. Representation varies significantly by company, location, and subsector, and is concentrated at large primes with long-standing IAM and SPEEA bargaining units.

The AIA/McKinsey 2025 study does not examine union status. Its findings center on pay: 88% of surveyed companies raised compensation for critical talent in the prior 12 months, and about eight in ten said leading candidates chose other offers based on salary. The study also points to persistent shortages of skilled technical workers and engineers at the mid-career level.

The ~15% attrition rate is industry-wide, and the same study found it ran highest among hourly (non-exempt) employees, at 15.9% in 2024. In a sector where losing an experienced, cleared machinist or systems engineer means months of recruiting, clearance processing, and on-the-job training before a replacement is fully productive, every dimension of the employment experience matters.

---

8. Safety, Injuries, and Workforce Risk

Aerospace and defense manufacturing involves precision assembly, testing, and production processes that carry inherent safety risks, though the sector’s injury profile differs from the broader construction and manufacturing landscape.

BLS Survey of Occupational Injuries and Illnesses (SOII) data for NAICS 336400 (Aerospace Product and Parts Manufacturing) show a total recordable case rate of 1.6 per 100 full-time workers in 2024, well below the 2.7 rate for manufacturing overall and the 3.2 rate for transportation equipment manufacturing. Rates vary inside the industry: aircraft manufacturing (2.0) and other aircraft parts and auxiliary equipment (2.1) run higher than guided missile and space vehicle manufacturing (0.6). Aerospace manufacturing tends to have lower rates of traumatic injuries compared to construction but faces elevated ergonomic and repetitive strain risks in assembly operations, particularly on aircraft and missile production lines where workers perform physically demanding tasks in confined spaces.

The connection between workforce planning and safety outcomes is direct. When production lines are understaffed, overtime increases, supervision is stretched thin, and less experienced workers are placed in positions that demand precision and attention to detail. In a sector where quality failures can be catastrophic (a faulty weld on a missile component, a missed inspection on an aircraft assembly) the stakes of understaffing extend far beyond OSHA recordables. They touch program integrity, mission readiness, and ultimately lives.

For A&D leaders, safety is not separate from workforce strategy. Firms with strong safety cultures and manageable workload levels are better positioned to attract and retain workers, reduce workers’ compensation costs, and avoid the production disruptions that follow serious incidents.

9. Productivity, Output, and Labor Costs

The productivity picture in aerospace and defense manufacturing is shaped by a fundamental tension: demand for output has never been higher, but the workforce to deliver that output remains constrained.

The BLS Industry Productivity program publishes annual output, hourly compensation, and unit labor costs for NAICS 3364 (Aerospace Product and Parts Manufacturing); the most current signals come from monthly and quarterly series. Across all of manufacturing, output per hour grew at a 2.4% annual rate in Q2 2026 and was up 1.1% from a year earlier, while hours worked rose 0.5% over the year, so the gain came from output growing faster than hours rather than from shrinking payrolls. Aerospace is expanding much faster than manufacturing as a whole: Federal Reserve industrial production for aerospace product and parts (NAICS 3364) was 4.7% higher in September 2026 than a year earlier, and employment grew 4.9% over the year to August 2026. Output and headcount are rising together, so the industry is hiring into its production ramp from the same constrained pool of skilled workers this report describes.

The commercial aerospace production environment illustrates the constraint. Boeing and Airbus held a combined backlog of more than 15,600 aircraft at the end of September 2026 (9,310 at Airbus and 6,371 at Boeing), giving OEMs years of production visibility. But as Deloitte’s 2026 A&D Outlook notes, shortages of materials and skilled labor will keep the A&D supply chain under pressure through at least 2027, which limits how quickly backlog converts into deliveries. The sector has demand it cannot fulfill because the workers to fulfill it are not available.

On the defense side, the constraint is even more acute. The Pentagon has asked suppliers to quadruple missile production, according to September 2025 press reports cited in Deloitte’s 2026 outlook, and the FY2026 budget request included $6.5 billion for conventional munitions production and $2.5 billion for production facility expansion. But physical capacity without workforce capacity is an empty building. Production rates are ultimately set by the number of qualified, trained, and in many cases cleared workers available to operate the lines.

The Golden Dome missile defense initiative illustrates the scale of the production challenge. The program received about $25 billion through the 2025 reconciliation law to begin work, and the administration requested $17.5 billion for FY2027, about 97% of it routed through a reconciliation package Congress has not enacted. Program leadership has warned that without that bill, Golden Dome has almost no FY2027 funding. The program envisions a multi-layered homeland missile defense architecture integrating space-based sensors, ground interceptors, and hypersonic defense capabilities. Its SHIELD contract vehicle, valued at up to $151 billion over a decade, now has more than 2,400 qualified vendors, up from the more than 1,000 firms named in the first award. An AIAA Institute policy paper cited estimates that the skilled labor pool would need to grow 30% to 40% to meet Golden Dome’s manufacturing surge, calling workforce readiness “a core enabler.” Without that workforce, the physical infrastructure and contract vehicles are capacity on paper only.

Deloitte estimates that 36% of tasks performed across industrial products manufacturing could benefit from augmenting human capabilities with agentic AI. This augmentation applies primarily to design, planning, logistics, and administrative workflows, not to the hands-on production roles (welders, assemblers, machinists) where shortages are most acute. Technology is augmenting the workforce in important ways, but the workers who remain must be trained to operate and oversee increasingly sophisticated digital systems, and the physical work of building aircraft, missiles, and spacecraft still requires human hands.

10. Defense Spending and Sector Outlook

$1.5 trillion Proposed FY2027 defense budget (subject to congressional action)

Understanding where defense spending is headed is essential for workforce planning, because spending growth directly drives labor demand, and the increase the administration has requested would be one of the steepest in recent decades.

The Pentagon’s FY2026 budget request totaled $961.6 billion, comprising $848.3 billion in discretionary funding and $113.3 billion in mandatory funding drawn from the 2025 reconciliation law. Congress enacted $839.2 billion in regular FY2026 defense appropriations in February 2026, roughly level with FY2025. That bill does not cover everything in the discretionary request; for the activities it does cover, Congress provided $8.4 billion more than requested. The reconciliation law separately provided $152.3 billion in defense funding available through FY2029. Requested FY2026 allocations that directly drive A&D workforce demand included:

• $6.5 billion for conventional munitions production ramp-up
• $3.9 billion for hypersonic weapons programs
• $25 billion for the Golden Dome missile defense initiative
• $47.4 billion for 19 new warships
• $2.5 billion for missile and munitions production facility expansion
• $179 billion for Research, Development, Test, and Evaluation (RDT&E) across base and reconciliation funding, a 27% increase over the prior year; Congress enacted $145.9 billion in regular FY2026 RDT&E appropriations
• $60 billion for nuclear triad modernization

In April 2026, the White House proposed a FY2027 defense budget of approximately $1.5 trillion ($1.15 trillion in base funding plus $350 billion expected from a reconciliation bill), an increase of more than 40% over the prior year. France 24 called it the sharpest increase since World War II and CNN said it would push military spending to its highest point in modern history. PolitiFact found it would be the largest increase since World War II in inflation-adjusted dollars, while the Korean War and World War II buildups were larger in percentage terms. The request prioritizes munitions stockpile replenishment, shipbuilding, and Golden Dome, and it arrived amid the war with Iran, which began with U.S. and Israeli strikes in February 2026 and remains unresolved despite a ceasefire.

As of October 2026, none of the increase has been enacted. FY2027 began on October 1 under a continuing resolution that runs through December 11, 2026, and holds defense near FY2026 levels. The House Appropriations Committee’s defense bill carries a $1.072 trillion discretionary allocation, the FY2027 defense authorization bill has stalled in the Senate, and neither chamber has made meaningful progress on the reconciliation package that would carry the $350 billion. The final appropriated amount will be determined by Congress and may differ significantly from the request.

Commercial aerospace is adding parallel demand. Boeing and Airbus order books remain near historic highs, with combined backlogs exceeding 15,600 aircraft. Engine MRO demand is at record levels. The global space economy reached $686 billion in 2025, and venture investment in defense technology reached a record $49.1 billion by PitchBook’s count.

Space and Lunar Programs Are Creating Sustained, Multi-Decade Workforce Demand

NASA’s Artemis II mission launched on April 1, 2026, sending four astronauts on the first crewed flight beyond low Earth orbit since Apollo 17 in 1972, a 10-day lunar flyby that ended with a safe splashdown on April 10. The mission validated the SLS rocket and Orion spacecraft that will carry a faster cadence of lunar missions. Artemis III is planned for summer 2027 as a 14-day mission in low Earth orbit in which Orion will attempt to dock with both SpaceX’s Starship and Blue Origin’s Blue Moon landers. Artemis IV, targeted for 2028, would be the program’s first crewed lunar landing, and NASA has committed to at least one surface landing every year after that.

The workforce implications are direct. NASA has issued a workforce directive to rebuild core civil servant engineering competencies and increase in-house development work alongside commercial partners. Boeing, the prime contractor for the SLS core stage, stated that its “workforce and supply chain are prepared to meet the increased production needs” of an accelerated launch schedule, though the company has faced well-publicized production and quality challenges across other programs in recent years. These missions are, in NASA’s words, “critical to an expanding space economy, fueling new industries and technologies, supporting job growth, and furthering the demand for a highly skilled workforce.”

Meanwhile, Boeing’s 2026 Pilot and Technician Outlook projects that the global aviation industry will require more than 2.4 million new professionals through 2045, including 674,000 pilots, 728,000 maintenance technicians, and 1,023,000 cabin crew members. Two-thirds of that demand will replace retiring personnel, and one-third will support fleet growth. Boeing has responded by expanding workforce training partnerships, including a five-year contract with Trident Technical College in South Carolina to onboard and recertify 787 Dreamliner assemblers and inspectors, with Boeing expecting to add up to 1,000 employees at the site over five years.

The global space economy reached $686 billion in 2025, and SpaceX’s June 2026 IPO, which raised about $75 billion at a $1.77 trillion valuation, shows that private capital is flowing into space and defense technology at a scale that will sustain workforce demand for years to come.

For workforce planning purposes, the key implication is this: every major segment of the A&D industry (defense manufacturing, commercial aerospace, space, cyber, MRO) is growing simultaneously, and they are all competing for the same finite pool of engineers, machinists, technicians, inspectors, and cleared professionals. Reconciliation funding and the proposed FY2027 increase have compressed what would have been a gradual ramp in workforce demand into more immediate pressure layered on top of existing structural shortages.

The firms competing for workers in 2026 and 2027 face competition from each other, from commercial tech, data center construction, and energy for the same skilled trades workers, and from every other defense contractor for the same cleared professionals.

11. What A&D Firms Expect Next

4.9% Year-over-year employment growth in aerospace product and parts manufacturing (BLS, Aug 2026)

The aerospace and defense industry heads into 2027 with strong demand and constrained capacity. Employment in aerospace product and parts manufacturing grew 4.9% in the year to August 2026 and exports rose 25% in 2025, yet the talent pipeline cannot keep pace with what the sector needs to deliver.

The AIA/McKinsey 2025 study describes an industry at an inflection point. Companies have invested heavily in attraction and retention through expanded recruiting channels, improved onboarding, and increased wages, but outcomes have not materially improved: attrition held near 15% in 2024, shortages in engineering and skilled trades remain a major constraint, and the gap between what the industry needs and what the workforce can deliver is growing.

The pivot the industry is making is toward productivity. McKinsey’s conclusion: “[T]he current approaches are no longer feasible. Instead, organizations must figure out how to do more with the workforce they already have, which means retaining the talent they’ve worked so hard to secure and driving a significant boost in productivity with that talent.”

AI, automation, and digital fluency are now the primary levers. AIA/McKinsey and Deloitte both identify AI-driven workforce augmentation as a key priority. The DoD is positioning AI as foundational across missions including modeling and simulation, operator assistants, and command and control. PwC reports that 57% of A&D executives are using AI-enhanced design and engineering to transform workflows, 16 points higher than the cross-industry average.

Labor dynamics are also influencing M&A. Buyers in A&D transactions are scrutinizing workforce depth, labor stability, and execution maturity during diligence. Sellers are under pressure to demonstrate that growth projections are achievable with the workforce available. In some cases, labor limitations are becoming a valuation issue. Government customers are also placing greater emphasis on delivery credibility.

The prevailing industry mindset has shifted from aggressive expansion to strategic optimization: finding ways to deliver more with constrained labor resources, invest in the workers already on board, and build flexibility into staffing models that allows firms to respond to program surges without overcommitting to permanent headcount.

Some conditions may ease. Congressional appropriations routinely reshape presidential budget proposals, and the FY2027 $1.5 trillion request may not survive the legislative process at that level. Attrition data from 2024 may not reflect improvements firms have made since. AI adoption could reduce headcount requirements in certain functions faster than current projections suggest. And cyclical softening in commercial aerospace demand, while not currently forecast, would relieve some of the simultaneous pressure on the labor pool. The structural constraints documented in this report, particularly demographics, clearance bottlenecks, and skills misalignment, are unlikely to resolve through any single factor. But the pace and severity of the near-term pressure depend on policy, spending, and technology outcomes that remain uncertain.

12. Future Workforce Outlook (2026 and Beyond)

Aerospace and defense workforce challenges are structural rather than cyclical. Even if hiring slows temporarily in certain segments, labor availability, skills alignment, clearance pipeline constraints, and demographic pressures will continue to shape workforce decisions for years to come.

The numbers tell a consistent story across multiple sources. The AIA/McKinsey 2025 study found that attrition at ~15% is, according to the study’s authors, more than double the cross-industry average, with production-critical roles facing the steepest exits. Nearly a quarter of A&D manufacturing and engineering employees are 55 or older. BLS projects aerospace engineer employment to grow 8% from 2025 to 2035, and aerospace technician employment to grow 12%, both much faster than the 3% average for all occupations.

Technology is augmenting, not replacing, the A&D workforce. Deloitte’s 2026 outlook describes an industry moving toward AI-driven analytics, autonomous systems, digital twins, and predictive maintenance. These are tools that increase output per worker but simultaneously increase demand for digitally skilled workers who can manage AI-augmented workflows. The majority of task hours in aerospace manufacturing are expected to remain human-driven for the foreseeable future, making workforce planning less about headcount reduction and more about reconfiguring roles for a digital operating environment.

The cleared workforce is a national security asset that cannot be quickly rebuilt. Clearance processing is government-controlled, takes months to years, and is subject to shutdown disruptions and agency capacity constraints. Firms that lose cleared workers lose not just an employee but a capability that can take most of a year to replace, since an initial Top Secret clearance alone now averages 243 days before recruiting time is counted.

The current increase in defense funding, which so far comes largely from the 2025 reconciliation law, has compressed what would have been a gradual decade-long ramp in defense workforce demand into a more immediate surge on top of existing structural shortages. The FY2027 proposed budget of $1.5 trillion, if enacted at or near that level, signals that defense spending will remain elevated, sustaining workforce pressure across every major A&D segment.

The demand signals extend well beyond defense. The Artemis program’s commitment to annual lunar landings from 2028 onward, combined with SpaceX’s commercial launch cadence, Boeing’s forecast of 2.4 million new aviation professionals needed through 2045, and estimates that Golden Dome could require a 30% to 40% larger skilled labor pool, all point in the same direction: the aerospace and defense industry will need more workers, across more skill categories, for a sustained period. And unlike previous defense buildups, today’s expansion is occurring against a backdrop of an aging workforce, constrained clearance pipelines, and competition from commercial technology sectors that did not exist a generation ago.

For firms navigating this environment, a build, buy, and borrow approach to workforce strategy applies directly:

• Build critical skills internally through apprenticeship, technical training, clearance sponsorship pipelines, and partnerships with technical colleges and K-12 institutions
• Buy specialized expertise through direct hire when specific skillsets or clearance levels are needed immediately
• Borrow flexible labor through contract staffing to manage program-based surges, production ramps, and the gap between contract award and clearance processing completion

No single approach to workforce development will be sufficient. Firms that combine internal development, targeted recruitment, flexible staffing, and proactive clearance pipeline management, while investing in safety, technology, and total compensation, will be better positioned to deliver against program commitments through 2027 and beyond.

What This Means for A&D Leaders

• Plan workforce strategy around total compensation and career development, not wages alone. While compensation is the top reason workers leave, culture, tools, and advancement pathways are what keep them.
• Treat clearance pipeline as a strategic asset: sponsor clearances proactively and don’t wait for program awards to begin the process.
• Track vacancy cost at the program level. AIA/PwC has cited industry estimates of roughly $20,640/month in unrealized revenue per unfilled cleared role, a figure worth monitoring even if directional rather than precise.
• Invest specifically in mid-career retention, as this is the cohort most vulnerable to attrition and most expensive to replace.
• Build early talent pipelines through technical colleges, veterans programs, and K-12 partnerships. The replacement generation takes years, not months, to develop.
• Don’t overlook the supply chain. Small and mid-tier suppliers face the same labor constraints as primes but without the brand recognition or compensation scale to compete for talent.
• Factor workforce depth into M&A diligence and contract bids, since labor availability is now a material risk factor and a determinant of delivery credibility.
• Close the salaried/hourly experience gap. The cultural divide between engineering teams and production workers is a contributing factor in disproportionate turnover on the shop floor.
