Test Flight
The Martin X-23 PRIME (Precision Recovery Including Maneuvering Entry) was a small uncrewed lifting body re-entry vehicle tested by the United States Air Force in the late 1960s. PRIME 1 was launched on 21 December 1966 on a mission to simulate a low-earth orbit reentry with a zero cross-range. The ballute deployed at 30.43 km, though the recovery parachute failed to completely deploy. The vehicle crashed into the Pacific Ocean and was not recovered.

SLC-3E is a launch pad at Vandenberg Space Force Base. It was originally built for the MIDAS program and later used for various other missions. After a period of inactivity, it was refurbished in the early 2000s to launch Atlas V rockets. The pad is now being upgraded to accommodate the new Vulcan Centaur rocket. The last Atlas V launch from SLC-3E happened in November 2022, with the first Vulcan launch expected in 2025.
