construction and development

The Adder , a pure turbojet engine was isolated from the gas generator (core engine) of the turboprop -Triebwerks Armstrong Siddeley Mamba derived and was originally called loss engine for driving the target drone Jindivik 1 developed. It was then developed into a long-lasting variant to ultimately form the basis for the Viper .

The flight tests of the Adder ASA.1 took place on board the Avro Lancaster III with the registration SW342 in the position of the rear gunner's position. This aircraft had previously been converted by Armstrong Siddeley's flight test department in Bitteswell and used for icing tests on the Mamba.
