For it slow, it appeared the sequence of experimental plane backed by means of the U.S. executive had run its path. among the past due Nineteen Forties and the past due Seventies, nearly thirty designations were allotted to airplane intended to discover new flight regimes or untried applied sciences. Then, mostly, it ended. yet there has been a resurgence within the mid- to past due- Nineties, and as we input the fourth 12 months of the recent millennia, the designations are as much as X-50.

Note the complete lack of vertical control surfaces.
In a concurrent test program to support the low-speed atmospheric flight dynamics of the X-37 design, the X-40A successfully completed its flight test program with seven successful flights at Edwards. During the series of flights, the unmanned X-40A was released from a CH 47 Chinook helicopter at 15,000 feet, and it autonomously acquired the runway and landed in a mode similar to a conventional aircraft. The X-40A demonstrated the guidance, navigation & control algorithms, software, calculated air data system, integrated GPS/INS, and aerodynamic performance of the basic X-37, and also used its mobile flight operations control center.
At least one of the YO-3As was later used by NASA as an acoustical signature research tool. One X-26B and a YO-3A are preserved in the Army Aviation Museum at Fort Rucker, Alabama. 34 American X-Vehicles: An Inventory X-1 to X-50 Lockheed-California Company X-27 First Flight: None Sponsors: Lockheed-California Last Flight: Not Applicable Fastest Flight: Not Applicable Total Flights: Not Applicable Highest Flight: Not Applicable The X-27 Lancer program can trace its roots to a Lockheed desire to develop a replacement for the F-104 Starfighter that was in wide service around the world.
