NASA picked McDonnell Douglas’ and later Boeing’s X-36 for a specific project. The project focused on fighter aircraft agility research. The X-36’s sleek design was primarily meant for one thing – warfare.
In 1997, NASA’s project team assessed and proved the tailless fighter design is a viable military option. The X-36 completed 31 flights via remote control. Its advanced technology improved mobility and ultimately survivability. The X-36 project surpassed all expectations.
$21 million of funding covered the manufacturing of the aircraft and the project requirements. After a successful test program, the X-36 retired and there’s no evidence that NASA or any other organization is developing the X-36 or any similar design.
