U.S. Air Force FY2027 Plans Acquisition of 24 New F-15EX Fighter Jets to Boost Homeland Missile Defense.

The U.S. Air Force is moving to expand its homeland air defense and long-range strike capabilities, planning to buy 24 Boeing F-15EX Eagle II fighters in the FY2027 budget, signaling that the Pentagon still sees heavy missile-carrying fighters as critical for countering growing air and missile threats. The $2.66 billion request, detailed in new budget documents, confirms the service will keep F-15EX production running through FY2031 as older F-15C/D jets approach the end of their combat life.

Built to carry significantly larger missile loads than stealth fighters, the F-15EX gives the Air Force a high-capacity interceptor and long-range weapons truck designed for homeland defense, Pacific operations, and future high-intensity conflict. The aircraft’s expanded payload and rapid fielding timeline reflect a broader U.S. strategy focused on increasing survivability, distributed firepower, and sustained air dominance against near-peer adversaries.

According to the U.S. Air Force FY2027 Aircraft Procurement budget justification documents published in April 2026, the aircraft will support both active-duty and Air National Guard units while preserving high-end air dominance alongside the F-35A fleet. The continued production profile highlights the Pentagon’s decision to maintain a mixed fighter structure combining fifth-generation stealth aircraft with heavily armed fourth-generation fighters optimized for missile load, endurance, and homeland defense missions.

The F-15EX program originated in the U.S. Air Force’s effort to rapidly recapitalize the aging F-15C/D fleet after years of structural fatigue concerns, declining readiness, and rising sustainment costs. In July 2020, the U.S. Department of Defense awarded Boeing an initial contract worth approximately $1.2 billion for the first production lot of F-15EX fighters, marking the formal launch of the Eagle II acquisition program. The original acquisition strategy envisioned up to 144 aircraft, although procurement objectives have evolved over time in response to broader Air Force modernization priorities and budget debates.

The Eagle II is derived from Boeing’s latest F-15QA and F-15SA export variants but incorporates mission systems tailored specifically for U.S. Air Force requirements. The aircraft features the AN/APG-82(V)1 Active Electronically Scanned Array radar, the Eagle Passive/Active Warning and Survivability System (EPAWSS), advanced digital avionics, fly-by-wire flight controls, large-area cockpit displays, and an open mission systems architecture designed to accelerate future software and weapons integration.

The modernization program behind the F-15EX is particularly important because it transforms a legacy Cold War-era fighter into a digitally enabled combat aircraft capable of operating within modern network-centric warfare environments. The Eagle II can carry more than 13 air-to-air missiles simultaneously and is designed to employ future long-range precision weapons, including hypersonic systems and stand-off strike munitions. This combination gives the Air Force a large-volume weapons carrier that complements stealth fighters during high-intensity combat operations.

One of the U.S. Air Force’s main operational drivers for the F-15EX program is the rapid replacement of older F-15C/D fighters, many of which entered service in the 1980s and are now experiencing increasing structural fatigue. Several Air National Guard squadrons continue to operate legacy aircraft, with increasing maintenance demands and declining readiness rates. The Eagle II allows the Air Force to recapitalize these units without requiring major infrastructure modifications because the aircraft uses existing F-15 basing and support systems.

The delivery of F-15EX aircraft is therefore strategically important for the U.S. Air Force because it directly improves readiness and operational availability while reducing transition risks for frontline units. Unlike introducing an entirely new fighter infrastructure, the Eagle II can be integrated rapidly into existing bases, maintenance systems, and pilot training pipelines. This enables faster fleet recapitalization at a time when the Air Force faces simultaneous pressure from global operational commitments, pilot shortages, and increasing demand for homeland defense alert missions.

The procurement strategy also reflects broader concerns about missile capacity in future Indo-Pacific conflict scenarios. While stealth fighters such as the F-35A are optimized for penetrating contested airspace, the F-15EX provides significantly larger payload capacity for long-range air-to-air missiles, hypersonic weapons, and stand-off strike munitions. This makes the aircraft particularly valuable as a “missile truck” supporting networked combat operations alongside stealth fighters, airborne early warning aircraft, and future Collaborative Combat Aircraft programs.

Industrial considerations also remain important. Continued F-15EX procurement sustains Boeing’s tactical fighter production line in St. Louis while preserving critical combat aviation manufacturing capacity within the U.S. defense industrial base. The Air Force has increasingly emphasized the need to maintain parallel fighter production ecosystems amid strategic competition with China, driving long-term demand for advanced combat aviation systems.

The FY2027 acquisition plan request demonstrates that the U.S. Air Force still sees a major operational role for heavily armed non-stealth fighters despite accelerating investment in sixth-generation air dominance programs such as the F-47 NGAD initiative. Rather than competing directly with stealth aircraft, the F-15EX is being positioned as a complementary force multiplier capable of delivering large missile loads, supporting homeland defense alert missions, and increasing overall combat mass during sustained high-intensity operations.
