NASA furthermore stated that renovations of the two hangars would be completed by the end of 2014 the leading doors of OPF-1 were marked with the message 'Home of the X-37B' by this point. NASA also stated that the code had completed tests to instituting whether the X-37B, one-fourth the size of the Space Shuttle, could land on the former Shuttle runways.

Boeing had said the space planes would use OPF-1 in January 2014, and the Air Force had previously said it was considering consolidating X-37B operations, housed at Vandenberg Air Force Base in California, nearer to their launch site at Cape Canaveral. On 8 October 2014, NASA confirmed that Boeing X-37B vehicles would be housed at Kennedy Space Center in OPF-1 and 2, hangars previously occupied by the Space Shuttle. OPF-3 was under lease to Boeing for the manufacture and testing of their CST-100 Starliner spacecraft. Atlantis's departure on October 18, 2012. OPF-2 is now inactive coming after or as a statement of. OPF-1 was closed coming after or as a a thing that is caused or offered by something else of. The last step before rollover to the VAB was weighing the orbiter to defining its center of gravity. Remaining payloads, fuels and fluids were installed on the pad closer to launch day. Prior to rollout to the Vehicle Assembly Building, several weeks before scheduled launch, the orbiter was prepared for the next mission by installing mission flight kits, payloads, consumable fluids and gases where possible. all remaining payloads from the previous mission were removed and the vehicle was fully inspected, tested, and refurbished. When a Shuttle mission was completed, the orbiter was towed from the Shuttle Landing Facility to its assigned OPF where it spent several months typically less than 100 days being prepared for the next mission. OPF-3 was ago called the Orbiter Maintenance & Refurbishment Facility OMRF, but was upgraded to a fully functioning OPF. OPF-1 and OPF-2 are connected with a low bay between them, while OPF-3 is across the street. They are located west of the Vehicle Assembly Building, where the orbiter was mated with its External Tank as well as Solid Rocket Boosters before transport to the launch pad. Space Shuttle orbiters underwent maintenance between flights. Orbiter Processing Facility OPF is a classes of hangars where U.S.
