One of the two X-37B vehicles flew the program’s first and third missions, which were known as OTV-1 and OTV-3, respectively.

The current OTV-5 mission began on September 7, 2018.

Before we begin, we would like to thank our sponsor NALA.

April 2010 marked the beginning of the OTV missions, with OTV-1 spending 244 days in orbit before touching down in December of that year.

Since OTV 3 would be a re-flight of the first flight vehicle, the refurbishment of that vehicle will play a major part of that decision.

This was the fifth flight mission of the Air Force under the Orbital Test Vehicle (OTV) program.

OTV-2's flight represents a big jump for the X-37B space plane.
