The Army's "Navy" helped to get damaged aircraft back into action and saved millions of dollars that would have been spent sending the aircraft back to the United States for repair. Once a week a Boeing built U.S. Army CH-47A Chinook helicopter (shown above) flew from An Khe, home of the 1st Calvary Division (Airmobile), to Can Ranh Bay and landed on the Army's first floating aircraft maintenance ship - the "Corpus Christi Bay." Aboard the Chinook were combat damaged aircraft parts. The Chinook carried repaired parts and equipment flown down from the central highland on previous flights. The "Corpus Christi Bay," the only ship of its kind at the time, was a 538-foot Military Sea Transport Service (MSTS) ship equipped to repair all types of Army aircraft flying in Vietnam. The 305 technicians aboard the ship were trained for work in sheet metal, hydraulics, instruments, electronics, armament, avionics and other fields. A technical library onboard used closed circuit television to save walking time. A camera in the library transmitted information from cards to television screens throughout the ship. The library contained over 500,000 items of information on repair and maintenance of Army aircraft.
