'''Orbiter Processing Facility''' ('''OPF''') is a class of [[hangar]]s where U.S. [[Space Shuttle orbiter]]s underwent maintenance between flights. They are located west of the [[Vehicle Assembly Building]], where the orbiter was mated with its [[external tank]] and [[Space Shuttle Solid Rocket Booster|Solid Rocket Booster]]s before transport to the launch pad. OPF-1 and OPF-2 are connected with a low bay between them, while OPF-3 is across the street.

OPF-3 was previously called the Orbiter Maintenance & Refurbishment Facility (OMRF), but was upgraded{{when|date=December 2018}} to a fully functioning OPF.
