The Bell Boeing V-22 Osprey traces back to April 1980 and Operation Eagle Claw, the failed attempt to rescue 53 Americans held in Tehran. At the Desert One rendezvous, helicopters hit a haboob sandstorm and broke down, and one collided with a C-130 in the dark, killing eight service members. The Pentagon launched the JVX program in 1981, and by 1983 Bell (wings, rotating nacelles, proprotors) and Boeing (fuselage, cockpit, avionics) teamed up to build a tiltrotor that could carry 24 troops, tilt its engines 90 degrees in about 12 seconds, and fly over 300 miles per hour. It flies only through a triple-redundant fly-by-wire system, and the FAA created a new powered lift category for it. The Marine Corps, worried about its own survival as a branch, became its champion.

Development costs jumped from $2.5 billion in 1986 to a projected $30 billion by 1988, partly because the wing had to rotate flat over the fuselage to fit amphibious ship elevators. Defense Secretary Dick Cheney tried to kill the program from 1989 to 1992, but Congress kept funding it. In April 2000 an Osprey crashed near Marana, Arizona, killing 19 Marines and four crew; investigators pointed to vortex ring state. As of early 2026, the episode counts 17 hull-loss accidents and 65 deaths, yet 2011 reports put its accident rate at about half the Marine rotorcraft average. The Army, which started JVX, left in 1988 and later chose the Bell V-280 Valor tiltrotor.

• In 2001 a Marine V-22 squadron commander was relieved of duty amid allegations that his unit falsified maintenance records.
• By 2002 an Osprey cost about $60 million, compared with roughly $35 million for a CH-53E with greater payload.
• A late 2023 crash off Japan killed eight crew and grounded the fleet across all branches for three months.
• In 2011 an Osprey flew from a ship in the Mediterranean deep into Libya to rescue a downed F-15 pilot.
• The Marines fielded it in Iraq in 2007, the Air Force CV-22 followed in 2009, the Navy CMV-22 in 2021, and Japan became the first foreign buyer.
