The 555th, one of the original RED HORSE units and the second squadron to arrive in Vietnam,
was headquartered at Cam Ranh Bay from February 1966 to early 1970.  The unit completed
much of the troop housing, roads, and utilities on the base.  The 555th constructed hundreds of
buildings, maintained AM-2 runways, taxiways, and parking aprons, and sent deployed units to
several other locations to construct facilities.  An 18-man unit constructed radar site facilities on Phu
Quoc Island, and the unit deployed a 50-man detachment to Nha Trang to accomplish major
construction projects at the direction of the 1st Civil Engineering Group.

The 555th was inactivated at Cam Ranh Bay on 15 December 1969.  Nearly 32 years later, on 21
August 2001 the unit was redesignated the 555th RED HORSE Squadron in preparation for
re-activation in the Air Force Reserve.  On 1 October 2001 HQ Air Force Reserve Command
activated the unit at Nellis AFB, Nevada, with assignment to the 610th Regional Support Group, to
augment the 554th RED HORSE Squadron at Osan AB, Korea.  Gaining command was Pacific
Air Forces.  The squadron became part of a unique Total Force squadron composed of the 554th
at Osan, the 254th RED HORSE Flight (Air National Guard) at Camp Murray, Washington, and
the 555th at Nellis.
