 Design and development
The TF41 was jointly developed by Allison Engine Company and Rolls-Royce from the latter's RB.168-25R Spey. Allison manufactured the TF41 under license, while Rolls-Royce supplied parts common to existing Speys. The TF41 was developed for use in the LTV A-7D Corsair II for the USAF, and the US Navy's A-7E. Between 1968 and 1983, a total of 1,440 TF41s were delivered.
