The first of its kind, F-15A Eagle, was a successful air superiority fighter. Of course there were some shortcomings, but most could be supplemented by measures over the next few years. One of them was the demand for more fuel, so the Production Eagle Package 2000 program began in 1977. Among with other changes, it eventually became F-15C.

The next step for F-15C was the Multi Stage Improvement Program (MSIP). Initially MSIP programs were planned in two ways, the MSIP I for F-15A/B and MSIP II for F-15C/D. However, MSIP I was canceled because it was considered uneconomical, leaving only MSIP II. By the MSIP II program, F-15C got new color display, Tactical Electronic Warfare System (TEWS) composed of AN/ALQ-135 ICS, AN/ALR-56C RWR, AN/ALQ-128 EWWS, AN/ALE-40/45 CMD, provisions for AMRAAM.

The MSIP II configured F-15C was first evaluated in December 1984, and MSIP changes were applied to production aircrafts from June 1985. The F-15C MSIP II completely overwhelmed Iraqi fighters during Operation Desert Storm, and has since been upgraded to continue its life. As of 2023, USAF still operates 86 F-15Cs.

Airframe, Engine

The airframe of the F-15C is an improved one, based on that of the F-15A. Thanks to the added fuel tanks, F-15C could hold about 2,000 lb (907 kg) more fuel internally. Due to the increased weight, some parts of the airframe were strengthened to handle extra weight. The main gear wheels were changed too.

To boost range and endurance, the provisions for conformal fuel tanks (CFTs) became standard. F-15C’s CFTs with missile launcher weighs 2,349 lb (1,065 kg) and could hold 9,631 lb (4,368 kg) of fuel. It is also drag efficient, since drag number of two CFTs (4.0) are less than that of the single 610 gallon external tank (5.5 or 12.2, depends on stations).

As like F-15A, F-15C used F100-PW-100 engine initially. The early F100 engine were powerful enough, but also had a reliability, maintenance, service life issues. These problems were solved in F100-PW-200 engine, by digital electronic engine control. This results in 300 lb (136 kg) and 400 lb (180 kg) reduction in each dry and afterburning thrust, while dynamic thrust was improved throughout most of the flight envelope due to more efficient power and fuel distribution. Though the PW-220 engine became available in 1986, the improvements were applied to the earlier PW-100 engine. These upgraded PW-100 engine is renamed to PW-220E.

F-15C uses AN/APG-63 PSP, the upgraded AN/APG-63 with programmable signal processor. The major differences between original APG-63 and APG-63 PSP is the addition of Raid Assessment mode for break out closely spread multiple targets, and superseded non-doppler mode. Original Pulse Search (PS) mode of APG-63 utilized low PRF waveform for look-up condition, but it was changed to medium PRF in APG-63 PSP.

Another notable feature is the Non-Cooperative Target Recognition (NCTR), which added to F-15C by MSIP II program. With the NCTR, the pilot could recognize type of enemy aircraft by radar reflection of engine fan blades. The effectiveness of NCTR proved during the Gulf War, because the rules of the engagement required at least two methods to identifying targets. The F-15C MSIP was the only aircraft with NCTR feature at that time, so Eagle drivers could easily identify target by AWACS and built-in NCTR.

The final 43 production F-15C/Ds were fitted with more capable AN/APG-70 radar. Later the AN/APG-63(V)1, which is even more capable than AN/APG-70, was introduced and retrofitted to legacy F-15C/Ds.

Armament, Countermeasures

The F-15C has a built-in M61A1 20 mm gatling gun with 940 rounds of ammo, and capable of carry four AIM-9 Sidewinder and AIM-7 Sparrow missiles each. F-15C acquired provisions for AIM-120 AMRAAM by MSIP II program, and the missile itself became available in 1991. The AMRAAM is lighter and smaller than Sparrow, so it could be loaded under wing using a LAU-128 launcher like a Sidewinder.

Because the F-15C is an air superiority fighter, its air-to-ground capability is limited to carrying and releasing some unguided bombs. In fact, even that is extremely rare in the U.S. Air Force.

Along with AMRAAM, the most important feature of MSIP program is addition of AN/ALE-40/45 countermeasure dispenser (CMD). The F-15C MSIP II has eight CMDs for 240 countermeasures.

I want all my Eagles big +1

Did I hear Eagle? big +1 for me

its probably following the line under f4E since we already have f16, f14 and the f111a

I think the F-15A should just be skipped over completely and this should be the first F-15 introduced, along with whatever SU-27 equivalent is

Then we should have a late model F-15C with AIM-9X block 2, AIM-120D, JHCMS, AN/APG-63(V)1 and all the other modern gadgets at a higher BR

kinda split on it, the us already has enough vehicles and other nations could need the love but it would be a very fun vehicle if added properly.

There’s a possibility that F-15C could be 12.7 BR and located after F-15A at rank 8

I guess gaijin could add F-15C (Early) with AN/APG-63(V)1 radar, armed IR AIM-9M & AIM-9M-9 sidewinder, SARH AIM-7MH sparrow and active-radar homing BVRAAM AIM-120A & AIM-120B AMRAAM

Eventually 100% and I guarantee Gaijin wouldn’t be dumb enough to skip it. The question really is BR and armament. I’d argue for an early mod with AMRAAM A/B and AIM-9M-9 at probably 13.3, and AN/APG-63(V)-1 AMRAAM C/D and AIM-9X/X-II at 14.7.

The ‘Early’ C should have the 63v1, with 9Ms and 120A/Bs. The ‘late’ C should be a Golden Eagle with 63v3, 9Xs, 120C/Ds, and the option of either an IRST pod or TGP on the centerline.


That’s exactly what I imagine Gaijin’s gonna do

It might F-15C showcase from first devblog season ? 🤔



This is 100% a new F-15 model, likely an F-15C. The nub for the Data link antenna can be seen on the nose barrel in front of the cockpit.

Edit:it’s not the satcom antenna, that is the square box behind it in the picture, nub is the datalink antenna



Does the f15c get hmd?

It should, yes. Unless gaijining happens like it did to the F-15A

F-15E Strike Eagle should be next 😍😍😍

Cool thanks for the reply

I don’t know after F-15A gaijin could add F-15C with AN/APG-63(V)1 radar or AN/APG-63(V)2 AESA radar but Air-to-Air armament early 2000’s and before equipped JHMCS

I can’t wait F-15E coming to USA tech tree for future major update

Nope, but McDonnell Douglas F-15C MSIP II has it

Would you happen to know if F-15C equipped, mounted, or tested MAWS?

To the best of my knowledge, if it did, it is not of the type gaijin currently implements, ie IR missile flash detectors
