The Commemorative Air Force Invader Squadron’s beloved Douglas A-26 Invader Night Mission—affectionately known as “BUBA”—needs a new engine. Currently the only airworthy Invader in the CAF fleet, Night Mission relies on continued support to remain flying and continue sharing the remarkable story of the A-26 Invader. Last year, we reported on Night Mission’s return to airworthy condition following a four-year restoration effort. After an outstanding season on the airshow circuit, the team was disappointed to discover a serious issue with the aircraft’s number two engine during a post-season 100-hour inspection.

In 2025, Night Mission returned triumphantly to the skies, dazzling thousands of spectators at airshows across Texas, including the prestigious Wings Over Houston Airshow, where the aircraft participated in a Vietnam War flight alongside legendary jets and fighters. Following a successful season, the crew was preparing for an ambitious 2026 schedule that would bring the Invader to airshow audiences across the United States. Unfortunately, “BUBA’s” number two engine had other plans. During the annual winter maintenance inspection, the crew focused on improving the aircraft by installing elevator gap seals and overhauling the nose landing gear, continuing the squadron’s commitment to safety and performance. However, while inspecting the number two engine, mechanics discovered several components outside acceptable tolerances. Out of an abundance of caution, the decision was made to replace the engine to ensure the continued safe operation of the aircraft.

Night Mission is currently the only flying Invader in the CAF fleet. With so few A-26s remaining airworthy today, preserving and operating this historic aircraft is especially important to the squadron. The Invader served in three major conflicts—WWII, Korea, and Vietnam—and stands as a flying tribute to the thousands of veterans who flew and maintained the type throughout its military career. The aircraft is powered by two Pratt & Whitney R-2800-27 “Double Wasp” engines—powerplants that are increasingly difficult to source and expensive to overhaul. Replacing and rebuilding the engine is expected to cost nearly $100,000, creating a significant financial burden for the squadron. Built by Douglas Aircraft in Long Beach, California, in 1943, Night Mission was delivered to the USAAF on December 8, 1944. The aircraft served until 1950 before entering civilian ownership. Over the decades, numerous caretakers preserved the aircraft before it was eventually acquired by the Commemorative Air Force, where it became known as Spirit of Waco. The Invader Squadron acquired the aircraft in 2009, and it would later become known as Night Mission.
The Invader Squadron, based in Fort Worth, TX, is asking for public support to help return Night Mission to the skies and continue sharing the story of this historic aircraft. Donations can be made through the CAF A-26 Invader Squadron donation page at this LINK.
