§ Mr. Pattie
The main contractors for the Sting Ray torpedo are Marconi Space and Defence Systems Limited, and final assembly of the weapon will take place at its new factory in Neston, Cheshire. The manufacture of parts is widely dispersed. Much of the weapon and its associated equipment will be made in the MSDS factories at Portsmouth, Frimley and Hillend, but a high proportion of the manufacturing work will be subcontracted. An exhaustive list of the many subcontractors is not readily available, but at present the main centres of the subcontracted work are Manchester, Willesden, Hemel Hempstead, Basildon, Rochester, Bracknell and Slough.
