Continental J69-T-25A Turbojet Engine

Collection Item Summary:

In mid-1951, Continental negotiated a licensing agreement with the French turbine engine company Turboméca for the technical, production, and marketing rights in the United States to the Marboré II turbojet. After an intense Continental marketing effort in 1952, Cessna selected the Marboré II (military designation J69) for its U.S. Air Force T-37 jet trainer, while Ryan Aeronautical chose it for some versions of its Ryan Firebee remotely piloted vehicle (RPV).

From 1954 through 1995, Continental produced more than 6,900 J69s for target and reconnaissance versions of the Firebee RPV. From 1955 through 1976, more than 3,000 were manufactured for the Cessna T-37. The J69-T-25A displayed here was manufactured in 1960 and powered the Cessna T-37B and C trainers.
