HC Deb 25 June 1969 vol 785 c262W
20. Mr. Wall

asked the Secretary of State for Defence what steps are being taken to provide for the air defence of the Fleet and the Merchant Navy when out of range of land bases.

Dr. David Owen

Outside the range of shore based air support, the main defence of H.M. ships and merchant shipping against air attack will be provided by existing Sea Cat and Sea Slug surface-to-air missile systems; the more advanced Sea Wolf and Sea Dart systems are under development.
