Versions of the F-15

Basic models

F-15A
Single-seat all-weather air-superiority fighter version, 384 built 1972-79.

F-15B
Two-seat training version, formerly designated TF-15A, 61 built 1972-79.

F-15C
Improved single-seat all-weather air-superiority fighter version, 483 built 1979-85.

F-15D
Two-seat training version, 92 built 1979-85.

F-15J
Single-seat all-weather air-superiority fighter version for the Japan Air Self-Defense Force 139 built under license in Japan by Mitsubishi 1981-97, 2 built in St. Louis.

F-15DJ
Two-seat training version for the Japan Air Self-Defence Force. 25 Built under license in Japan by Mitsubishi 1981-97, 12 built in St. Louis.

F-15N Sea Eagle
The F-15N was a carrier-capable variant proposed in the early 1970s to the U.S. Navy as an alternative to the heavier and, at the time, considered as "riskier" technology program: F-14 Tomcat. The F-15N-PHX was another proposed naval version capable of carrying the AIM-54 Phoenix missile. These featured folding wingtips, reinforced landing gear and a stronger tail hook for shipboard operation.

F-15E Strike Eagle
See F-15E Strike Eagle for F-15E, F-15I, F-15S, F-15K, F-15SG, F-15SE and other F-15E-based variants.

Research and test

F-15 Streak Eagle (72-0119)
One stripped and unpainted F-15A, demonstrated the fighter's acceleration – broke eight time-to-climb world records between 16 January and 1 February 1975. It was delivered to the National Museum of the United States Air Force in December 1980.

F-15 S/MTD (71-0290)
The first F-15B was converted into a short takeoff and landing, maneuver technology demonstrator aircraft. In the late 1980s it received canard flight surfaces in addition to its usual horizontal tail, along with square thrust-vectoring nozzles. It was used as a short-takeoff/maneuver-technology (SMTD) demonstrator.

F-15 ACTIVE (71-0290)
The F-15 S/MTD was later converted into an advanced flight control technology research aircraft with thrust vectoring nozzles.

F-15 IFCS (71-0290)
The F-15 ACTIVE was then converted into an intelligent flight control systems research aircraft. F-15B 71-0290 is the oldest F-15 still flying as of January 2009.

F-15 MANX
Concept name for a tailless variant of the F-15 ACTIVE, but the NASA ACTIVE experimental aircraft was never modified to be tailless.

F-15 Flight Research Facility (71-0281 and 71-0287)
Two F-15A aircraft were acquired in 1976 for use by NASA's Dryden Flight Research Center for numerous experiments such as: Highly Integrated Digital Electronic Control (HiDEC), Adaptive Engine Control System (ADECS), Self-Repairing and Self-Diagnostic Flight Control System (SRFCS) and Propulsion Controlled Aircraft System (PCA). 71-0281 was returned to the Air Force and became a static display at Langley AFB in 1983.

F-15B Research Testbed (74-0141)
Acquired in 1993, it was an F-15B modified and used by NASA's Dryden Flight Research Center for flight tests.
