Variants

The first model, the JT15D-1, was introduced to power the Cessna Citation I, then known as the Fanjet 500. Deliveries started in 1972, and eventually on 1,417 -1s were delivered. The JT15D-4 was introduced the next year, improving thrust to 2,500 lbf (11,000 N). The -4 was the primary engine for the Cessna Citation II, and went on to find use on the Mitsubishi Diamond 1A, Aerospatiale Corvette and SIAI Marchetti S.211. Eventually 2,195 engines of the -4 series were delivered.

The next major model was the JT15D-5, certified in 1983. The first versions delivered 2,900 lbf (13,000 N) and were used on the Beechjet 400A and Cessna T-47A. Several minor versions were introduced, the -5A for the Cessna Citation V, while the -5B powered the Beechcraft T-1A Jayhawk, the -5C the DASA Ranger 2000 and S-211A.

A more major upgrade was the JT15D-5D, which was certified in 1993. It increased thrust again, this time to 3,045 lbf (13,540 N). The -5D is used on the Cessna UC-35A and Cessna Citation Ultra.
