Spooks and Super Jollies: the story of the MH-53 family

Article Abstract:

The Sikorsky MH-53, long-considered as the backbone of the AFSOC, entered the service in 1967 as a replacement for the short-ranged HH-3F. The helicopter, built primarily for endurance and range, is due to be retired and replaced by the Bell Boeing CV-22 Osprey by 2004. However, despite its impending retirement, the Super Jolly Green continues to receive upgrades. The latest incarnation of the Sikorsky MH-53 is the MH-53M Pave Low IV version.

Testing times for MV-22

Article Abstract:

The Bell-Boeing V-22 fleet has been grounded once again following the discovery of a loose gimbal ring bolt in a prop-rotor gearbox during a maintenance inspection of one of the US Marine Corps aircraft. The grounding has led to concerns that the Defence Acquisition Board may nott approve clearance for full rate production until members are better satisfied that the tiltrotor meets safety and reliability criteria.
