§ Sir Frederick Burden
asked the Secretary of State for Defence what is the present estimated cost of developing the second and third stream of the SSN refit facilities at Devonport planned for completion in 1986.
§ Mr. Blaker
The facilities that have been provided at Devonport were originally intended to support two SSN streams and the increase to three streams will largely be met by increased utilisation of these. Some additional facilities will be required and studies are in hand to determine the precise needs but additional capital expenditure arising from three-stream refitting is expected to be relatively small.
