Teledyne CAE F408-CA-400 (Model 382-10)

F408 was developed for such UAVs as the Ryan BQM-145A Peregrine, aerial targets, standoff and cruise missiles in the 4.45 kN (1,000 lb) thrust class. Teledyne Continental Model number was 382-10.

F408 had been also used on the Eclipse 500 prototype.

Development began in 1985.

Its classification was "Bypass turbojet" with a ratio about 0.25. 

The engine had a fan stage followed by a mixed-flow compressor, slinger type combustor, and a single-stage turbine. The compressor and fan design drew on CAE's earlier advanced technology  work, while the turbine was similar to that used in Model 373-8B. A major purpose of the bypass feature was to cool the engine skin, which greatly simplified missile engine installation. 

The engine first run in 1989.
