The 104th Fighter Wing has marked a major milestone in its F-35A transition by signing the fuselage bulkhead of one of its first aircraft at Lockheed Martin’s Fort Worth facility. The event highlights the Air National Guard unit’s shift from the F-15 Eagle to the fifth generation F-35A, securing its future mission and expanding operational capabilities.
104th Fighter Wing F-35A Transition Reaches Major Milestone
The 104th Fighter Wing F-35A transition moved one step closer to reality after senior leaders from the Massachusetts Air National Guard visited Lockheed Martin’s production facility in Fort Worth, Texas, to sign the fuselage bulkhead of one of the wing’s first F-35A Lightning II aircraft. The ceremony marked a symbolic and operational milestone as the unit prepares to receive its first fifth generation fighters.
According to the 104th Fighter Wing, the visit took place on May 27 and included wing leadership, pilots, and senior enlisted personnel. Signing a partially assembled aircraft is a long standing military aviation tradition that allows future operators to leave their mark on an aircraft while it remains on the production line.
For the Massachusetts-based unit, the moment represented far more than a ceremonial event.
Col. Michael Glass, commander of the 104th Fighter Wing, described the signing as a pivotal moment that reinforces the future of the wing and its readiness mission. Wing leaders emphasized that the arrival of the F-35A secures the unit’s long term role within the Air National Guard and the broader U.S. Air Force force structure.
From F-15 Eagles To Fifth Generation Fighters
The 104th Fighter Wing previously operated the F-15 Eagle for nearly two decades. The aircraft served at Barnes Air National Guard Base from 2007 until the fleet was retired from the unit in 2025 as part of a broader Air Force modernization effort.
The transition to the F-35A represents one of the most significant capability upgrades in the wing’s history.
Unlike the F-15C, the F-35A combines low observable characteristics, advanced sensors, electronic warfare systems, and data fusion capabilities into a single platform. The aircraft is designed to operate effectively in highly contested environments while sharing information across joint and allied networks.
This transition reflects a wider trend across the Air National Guard, where legacy fourth generation fighter fleets are increasingly being replaced by fifth generation aircraft capable of supporting modern air superiority and multi domain operations.

The Fort Worth facility remains the centerpiece of global F-35 production. According to the 104th Fighter Wing, the assembly complex can accommodate up to 155 aircraft simultaneously, while each F-35 requires roughly 18 months to move from initial assembly to final delivery.
The signing ceremony also gave wing personnel a firsthand look at aircraft already progressing through production.
The event follows another major milestone announced in May, when the 104th Fighter Wing received more than 1,000 pieces of support equipment valued at nearly $1 billion. Those deliveries included critical infrastructure and logistics systems required to sustain F-35 operations at Barnes Air National Guard Base.
Taken together, the equipment deliveries and aircraft production progress indicate that the wing’s conversion effort is entering a more advanced phase.
Why The F-35A Matters For The Air National Guard
The significance of the 104th Fighter Wing F-35A transition extends beyond Massachusetts.
Across the United States, Air National Guard units play a critical role in homeland defense, expeditionary operations, and contingency response. Equipping Guard units with the F-35 ensures that reserve component forces remain interoperable with active duty, allied, and coalition air forces operating the same platform.
(adsbygoogle = window.adsbygoogle || []).push({});The F-35’s sensor fusion capabilities allow pilots to detect, track, and share information across the battlefield more effectively than legacy fighters. As potential adversaries field increasingly sophisticated air defense systems and advanced combat aircraft, access to fifth generation capabilities becomes increasingly important for maintaining operational effectiveness.
The transition also preserves the strategic relevance of the 104th Fighter Wing within future force planning. Air National Guard units selected for F-35 operations are expected to remain integral contributors to U.S. airpower for decades.
Strategic Analysis
While the fuselage signing itself was ceremonial, the broader significance lies in what it represents.
The U.S. Air Force continues to balance modernization requirements against budget pressures, force structure changes, and evolving global threats. Selection for the F-35A demonstrates confidence in the 104th Fighter Wing’s operational record, infrastructure, and long term value to national defense.
The transition also underscores a larger shift within the Air National Guard toward maintaining frontline combat relevance. Rather than relegating Guard units to legacy platforms, the Air Force is increasingly integrating them into advanced combat aviation planning.
For Barnes Air National Guard Base, the arrival of the F-35A secures a future mission set that is expected to remain central to U.S. airpower well into the 2040s and beyond.
Conclusion
The 104th Fighter Wing F-35A transition reached a visible milestone with the signing of one of the unit’s first aircraft at Lockheed Martin’s Fort Worth production facility. As aircraft move through final assembly and support equipment continues arriving in Massachusetts, the wing is steadily progressing toward full fifth generation operations.
The event highlights not only the future of the 104th Fighter Wing but also the continuing modernization of the Air National Guard as it prepares for the demands of future air combat.
