McDonnell Douglas F-15B “Dual-Role Fighter” (DRF) Prototype

Brief History:

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.

    One chaff bundle loaded into speedbrake


    2-8x AN/ALE-40/45


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.

Air-Minded: Speedbrake Chaff


Weapons Loadout:

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


    AN/AVQ-26 Pave Tack targeting pod 
    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.











+1 yes please

Needs countermeasures, but would be very cool

Voting 11.7 feels kind of insane, it has no countermeasures and weaker engines. Am I missing something?

It would be stronger than F14B, maybe close to 11.7, but I am not sure if gaijin wants to add countermeasures

I think the big thing here is that it wasn’t possible for this thing to get CMs.
The F-15A/Bs and F-15C/Ds that did got them under a pretty intensive modernization program (MSIP II), but there were no CM pods ever fitted or even prototyped beforehand (as it wasn’t part of USAF doctrine yet).
Same happened with the French F-8E (FN) Crusader
