Polaris, Chevaline And Trident Dr. McDonald asked the Secretary of State for Defence if he will publish in the Official Report the numbers of employees directly and indirectly involved (a) in the refurbishing of Polaris, (b) on Chevaline and (c) on Trident or expected to be employed on the Trident project. Mr. Pattie If by refurbishing of Polaris, the hon. Member refers to the programme to produce new motors for Polaris, this is being undertaken in the United States and does not involve additional employment in the United Kingdom. On Chevaline, the development programme has been essentially completed. Production and minor residual development tasks, together with post-design support, currently involves some 1,700 jobs in industry and the Ministry of Defence: these mumbers will reduce during the period in which Chevaline is deployed operationally. The Trident programme is estimated to involve in its peak year some 20,000 jobs in direct employment in United Kingdom industry and another 15,000 in indirect employment.
