This topic is meant to suggest that the Strike Eagle prototype F-15B serial number 71-0291 be added to War Thunder in the USA air tree. This aircraft was submitted into the early 1980’s “Dual-Role Fighter” (originally called the Enhanced Tactical Fighter) program against the F-16XL in a bid to replace the F-111 Aardvark in the ground strike role while also maintaining its air-to-air capabilities. The F-15 would go on to win this competition and become the F-15E Strike Eagle.
‘291 Prototype’ differences compared to production F-15E include:
- No countermeasures.
- No internal cannon.
- F100-PW-100 engines instead of more powerful F100-PW-220/229.
- Used only AIM-7 and AIM-9 missiles, no AIM-120.
- Access only to early PGMs compatible with Pave Tack pod.
- AN/APG-63 with synthetic aperture radar (SAR) and ground-mapping modifications.
F-15B-2, AF Ser. No. 71-0291
First flew on 18 October 1973 as a TF-15A and used as a test and demonstration aircraft. In 1976 it made an overseas sales tour painted in markings to celebrate the bicentenary of the United States. Also used as the development aircraft for the F-15E as well as the first F-15 to use Conformal Fuel Tanks. On July 8, 1980, the prototype McDonnell Douglas F-15 Strike Eagle, a fighter-bomber variant converted from the second two-seat F-15B Eagle trainer, F-15B-4-MC 71-0291, made its first flight. The 71-291 airframe had other uses as flight/technology demonstrators for the Air Force and NASA.

Countermeasures on the early F-15 Eagles has been a particular point of interest for me. From my research I have concluded that F-15A/B did not use flare or chaff dispensers until 1985 with the F-15C MSIP upgrades that were retrofitted on some F-15A/B models. Provisions are available on the early Eagles but were nevertheless unused in operational service for whatever reason.
The HOTAS throttle has a flare/chaff dispensing switch, and wiring is present for up to eight dispensers on the underside of the fuselage in front of the rear landing gear.
Alternatively, there are reports that Eagle crew chiefs would routinely load a single-use bundle of chaff into the dorsal speedbrake that was only dispensed by deploying the brake.
Whether or not this aircraft should get countermeasures is up to Gaijin for interpretation.
Cannon: None internally GPU-5/A 30mm (GEPOD 30) gun pods mounted externally A-A Missiles: AIM-9E/-9J/-9L Sidewinder AIM-7F Sparrow A-G Ordnance: Mark 82/83/84 (LDGP, Snakeye) GBU-8/-10/-12/-15/-22/-24 guided bombs CBU-52/-58/-71 cluster bombs BLU-27B incendiary bombs BDU-38 nuclear bomb AGM-65A/B/D Maverick AGM-84 Harpoon Pods: AN/AVQ-26 Pave Tack targeting pod OR LANTIRN targeting pod (early development version) AN/ALQ-119(V) ECM pod 1-3x GPU-5/A 30mm (GEPOD 30) gun pods
The cannon on the 291 model was removed for this prototype flight demonstration and was later re-added. It was extensively tested with external gunpods. Similar to the countermeasures, the decision to include an internal gun or leave it to use external pods exclusively is up to Gaijin’s balancing interpretation.
