Savoia,
Many thanks for the pics, though the last picis of the then 67th Aerospace Rescue and Recovery Squadron HH-53H Super Jolly Green Giant not USMC CH-53!
In the 80s the 601st Tactical Air Control Wing at the former Sembach AFB now Sembach-Kasserne USAREUR base operated the cargo CH-53H and OV-10 Bronco (FAC) . The H-53 of the 601st had a role of carrying battlefield radar and mobile ATC and surveillance radars.
Originally at Woodbridge and post Desert Storm and closure of bases as the 21st SOS Dust Devils as part of the old 39th Special Ops Wing then moved to Alconbury and in 93 to 95 relocated to Mildenhall as Alconburys airfield would cease ops and that part of the base given back to the MOD. 39th was re designated 352nd Special Operations Group then in 2007 the MH-53M Pave Low I'VE retired from USAF inventory and 21st SOS disbanded. But it will reform with cV-22 late or early next year at Mildenhall.
USMc don't have helos in UK unless on exercise or attending airshows such as RIAT or Farnborough
Many thanks
