The Armstrong Siddeley Adder was an early British turbojet engine developed by the Armstrong Siddeley company and first run in November 1948.[1]

Design and development

The Adder, a pure-jet derivative of the Armstrong Siddeley Mamba, was originally developed as an expendable engine to power the Jindivik 1 target drone. The engine was then developed into a longer-life engine before evolving into the more-powerful Armstrong Siddeley Viper.

The ASA.1 Adder was flight tested in the rear-turret position of the Avro Lancaster III SW342, the aircraft also having been previously modified and used for icing trials of the Mamba by Armstrong Siddeley's Flight Test Department at Bitteswell.
