Armstrong Siddeley Viper position meetings: Notes on a meeting held to review the...

Mr Saxton stated that he had called this meeting with a view to obtaining a more clear understanding of the position regarding both short-life and long-life engines, for the purpose of assessing the possibility of maintaining programme deliveries for the existing contracts, and to outline the possible future requirements. Section 1 Short-life engines: 2 Dassault engines have been delivered. MoS 65 engines had been delivered and we are 19 engines behind the delivery programme. MoS 60 engines (2nd batch) Delivery was scheduled to commence in January 1954. However, there might be some difficulty in maintaining this programme due to the short time available in which to obtain material. USA and Swedish enquiries: There are problems in the estimates for engine batches from 300 to 1000. Section 2 Long-life engines: Conversion engines for MoS development. Delivery would be in July, August and September. Supply of 15 engines for MoS: Were required for CS(A) Aircraft.
