The ATF3 was first flown in the Teledyne Ryan YQM-98 Compass Cope R high altitude UAV, as the YF104-GA-100. The engine proved to have a very low infrared signature, as the hot turbine was not externally visible and the core exhaust mixed with the bypass air before exiting the engine. The pilots of U-2 high altitude chase planes reported being unable pick up the YQM-98A with either radar or IR sensors.[2] It was later used in the Northrop Tacit Blue stealth demonstrator because of these characteristics.[3]
The most significant application of the engine was on the Dassault HU-25 Guardian, developed for the US Coast Guard. It was also used on the Dassault Falcon 20G and Dassault Falcon 200.[3]
