Intended for the smaller civilian jet airliner market when it was being designed in the late 1950s, the Spey concept was also used in various military engines, and later as a turboshaft engine for ships known as the Marine Spey, and even as the basis for a new civilian line, the Rolls-Royce RB.183 Tay.
Aviation versions of the base model Spey have accumulated over 50 million hours of flight time.[1] In keeping with Rolls-Royce naming practices, the engine is named after the River Spey.
