Delivery to the UK of a new SIGINT aircraft for the Royal Air Force has been postponed. The UK’s Military Airworthiness Authority (MAA) has not yet reviewed the safety case. The Airseeker (the RAF’s name for the U.S. Air Force RC-135 Rivet Joint system) is the latest airframe that could be delayed by the MAA’s detailed scrutiny, which British defense contractors have privately called overzealous. Others have included the Beechcraft Super King Air 350ERs acquired by the Royal Navy for observer training; the Airbus A330MRTTs entering RAF service as a refueling tanker; and the Thales Watchkeeper UAV for the British Army.
