Defense and aerospace owners are heading into 2027 with little room for slow capital decisions. Production demand is rising, supply chains remain under scrutiny and many critical facilities are being asked to support missions or rates they were not originally designed to carry. The result is a more complex project environment in which construction, manufacturing strategy and operational readiness are tightly connected.
The U.S. aerospace and defense industry generated $988.6 billion in total sales in 2025, reflecting demand across commercial aviation, defense and space markets, according to the Aerospace Industries Association’s 2026 Facts & Figures report. That total includes $506 billion in direct output and nearly $483 billion in activity across the domestic supply chain. The industry also produced $500 billion in economic value and supported more than 2.1 million jobs. Capital expenditures reached $45 billion, up 13% compared to 2024, with much of that investment tied to original equipment manufacturers and related machinery subsectors.
For owners, those numbers represent more than market growth. Many defense and aerospace projects involve secure environments, specialized production processes and long-lead equipment. These projects also carry strict compliance requirements and often take place inside facilities that must remain operational during construction.
In 2027, the aerospace and defense project owners positioned to respond effectively to an ever-changing market will align facility strategy with production needs early. Following are four important trends that will help shape that work:
Capacity and supply chain resilience will drive more capital planning decisions. Manufacturing capacity will remain a central issue for defense and aerospace project owners in 2027. Demand tied to aircraft, munitions, space systems and ship-building support has made industrial capacity a national security priority. The Department of Defense’s National Defense Industrial Strategy Implementation Plan identifies production capacity, resilient supply chains and infrastructure modernization as priorities for strengthening the defense industrial base. For owners, that policy direction reinforces a practical reality: readiness depends on facilities that can support production at the required pace. For construction teams, this translates into having the capacity needed to expand production. New and upgraded facilities may need more reliable utilities, secure storage, controlled environments and infrastructure designed around sensitive operations, including storing, inspecting and testing. Supplier networks may need capital improvements to meet program expectations for traceability, quality and compliance without creating bottlenecks. For effective capacity planning in 2027, owners will need to know without a doubt if a site can support phased growth, utilities can keep pace with production and whether a facility is resilient and can adapt as missions change.
Speed to mission will continue influencing project delivery expectations. Project delivery expectations are changing as defense and aerospace programs place more emphasis on readiness and faster production. Deloitte’s 2026 Aerospace and Defense Industry Outlook describes speed to field as a unifying metric across portfolios and notes continued pressure around delivery reliability, the industrial base, cost, supply chains and workforce constraints. That pressure will intensify in 2027. Owners will expect delivery teams to define scope earlier, identify long-lead equipment sooner and bring construction knowledge into planning before major design decisions are finalized. Security requirements, procurement timing, permitting, commissioning and operational constraints all need to be considered at the start. Design-build and progressive delivery models, along with early procurement of long-lead equipment, can support that level of coordination. These approaches can reduce handoffs, bring construction insight into design decisions and create clearer paths for early procurement, especially for manufacturing projects where coordination is important because equipment, process flow and building systems are closely connected. Effective project teams in 2027 will be the ones that make risk visible early. Cost, schedule, utilities, production needs and commissioning should be discussed together, not managed as separate tracks. That alignment gives owners a stronger basis for decisions when requirements change.
Existing facilities will carry more mission demand. New facilities will remain important, but existing facilities will carry a large share of defense and aerospace demand in 2027. Across the country, depots, manufacturing plants, test facilities, hangars and secure environments are already supporting active operations. Upgrading those facilities without disrupting missions can be more complex than building new. The Congressional Budget Office (CBO) reported that the Department of Defense’s 2026 budget request totaled $961 billion, including $113 billion in funding provided by the 2025 Reconciliation Act. CBO also noted that, after adjusting for inflation, the request was one of the largest over the past 50 years. For facility owners, this environment reinforces the value of sustainment, restoration, modernization and phased construction. Targeted upgrades can increase capacity without waiting for a new building program.
Digital delivery will become more practical and operations-focused. Digital delivery will become more integrated into projects and operations in 2027. Deloitte reports that U.S. aerospace and defense spending on artificial intelligence (AI) and generative AI is expected to reach $5.8 billion by 2029, about 3.5 times the 2025 level. For construction and manufacturing projects, the most valuable digital tools will reduce rework, improve coordination and support long-term facility performance. A digital model can help coordinate equipment clearances before steel is ordered. Reality capture can document existing conditions inside active facilities. Advanced scheduling can show how procurement delays affect commissioning. Digital twins can help operations teams understand how a facility will perform after turnover. These are not four separate challenges. They are four ways of asking the same question: Can a facility absorb more, faster, without stalling missions? Capacity without a resilient supply chain still creates bottlenecks. Fast delivery without modernized existing facilities still encounters physical and operational challenges. Readiness is not the sum of these trends. It’s the single constraint they all run into.
Readiness Starts With the Facilities Behind the Mission
Effective capital programs will connect facility, manufacturing and delivery strategies before major decisions are finalized. That early alignment can help teams manage risk, make clearer trade-offs and deliver facilities that support long-term production strength. Owners developing 2027 capital plans should pressure-test those connections before design advances. These are the conversations our aerospace and defense team is having with owners as they develop their 2027 capital plans because early alignment often determines whether a program delivers its intended value, both regarding long-term manufacturing goals and overall mission objectives.
