Built as a HH-53C and over the years converted to HH-53H, MH-53J and the highly capable MH-53M Pave Low IV version. Has a turbulent history including recovery of Jonestown Massacre victims in 1978, Desert Storm operations in 1991 and the first ever night landing at Buckingham Palace, in 2003 supporting the Bush visit as a 21st SOS machine from Mildenhall. Retired by the 20st SOS in 2008 and on loan here from the USAF Museum since 2010. The nose art above the name features Marvin the Martian firing a machine gun, with 'Desert Storm 1991' written in all-capitals on the same panel.
