Bell Textron and Korea Aerospace Industries (KAI) signed a memorandum of understanding on April 28, 2026, in Fort Worth, Texas, to evaluate an MV-75 Cheyenne II tiltrotor for South Korea’s High Speed Medium Utility Helicopter (HSMUH) program.
The agreement marks the first public international collaboration for Bell’s MV-75 since the U.S. Army designated it Cheyenne II earlier in April 2026. The partners will assess MV-75-based solutions incorporating a modular open systems approach (MOSA), allowing Republic of Korea (ROK) forces to modify the weapons system independently over time.
Discussions also cover potential industrial cooperation in South Korea, though no specifics on workshare, schedule, or financial terms were released. The MV-75, with an expected maximum takeoff weight of around 30,000 pounds, offers helicopter-like vertical takeoff combined with tiltrotor speed, range, and maneuverability.
The effort aligns with U.S. government priorities and receives support from the U.S. Army Contracting Command at Redstone Arsenal under the Future Long-Range Assault Aircraft (FLRAA) contract, linking any potential export to U.S. technology release policies.
