. "The Sikorsky MH-53 Pave Low series is a long-range combat search and rescue (CSAR) helicopter for the United States Air Force. The series was upgraded from the HH-53B/C, variants of the Sikorsky CH-53 Sea Stallion. The HH-53 \"Super Jolly Green Giant\" was initially developed to replace the HH-3 \"Jolly Green Giant\". The helicopters later transitioned to Special Operations missions. The U.S. Air Force's MH-53J/M fleet was retired in September 2008 and was replaced by the CV-22B Osprey."@en . "2008-09-30Z"^^ . .
