The designation XRIM-113A, indicating an experimental ship-launched interceptor missile, was allocated to the SIRCS project in May 1976, and contracts were awarded to three separate teams of contractors -
RCA/
Martin-Marietta,
McDonnell Douglas/
Sperry, and
Raytheon/
Lockheed/
Univac - for initial studies of the SIRCS missile concept, in anticipation of a competitive evaluation. By 1978, the study phase of development was completed. The McDonnell Douglas/Sperry team had examined the use of the
British Aerospace Sea Wolf missile, which failed to meet the full specification, but was the only existing missile that approached the SIRCS requirements. Sea Wolf was anticipated to be able to enter service in 1979 if selected as a worthwhile basis for the further development; a newly designed missile would push the expected in-service date to 1983. However, the
United States Congress refused to allocate funding for the further development of the RIM-113 missile. A proposal was made for joint development of SIRCS with the
U.S. Air Force's AMRAAM project;, but this came to naught, and the RIM-113 was cancelled in 1979. ==References==
