anyone else notice the F15 on the dev server has too low a top speed up high? I know deck speed is right where charts show (800kts ish) but above 40,000’ we should be pushing 2.5M but instead it stops at 2.3M… for as long as i can remember, the f15 has been touted as a 2.5M+ capable aircraft, anyone reported this?

1425 knots is 2.13 mach, it’s not doing 2.5 mach with 4x AIM-7F and 2x Mk84.

should be going 2.5 clean though

Are you looking at F-15A or F-15C performance, if it had the F-15C’s F100-PW-220 it should be more capable of 2.5 mach.

We have this one in-game:
F-15A clean with PW-100 engine is less than 2.4 mach top speed

i see. does the f15j get pw 220s?

irl i mean

They incorporated them at some point as did the US but the models we have in-game probably ain’t changing.

1425 isn’t 2.13M, least in standard conditions which i think test flight simulates. here’s a M calculator Airspeed Conversions (CAS/EAS/TAS/Mach) | AeroToolbox

and im in test flight now doing 2.3M and 1300knots @ 45,000’. so about 125knots short.

sorry for extra us main copium but this really does make me wish we got a 1986 f15c or equivelant

heres the source im using. PW-100 engines.

this is best I could pull though still very close

we should of received MSIP F-15Cs all around this update even with out aim-120s we would still have gotten a better radar, new engines HMD

They’ll reference the manuals first before the SAC though both are primary sources.

we’ll probably get 15cs next update or the patch after that along with amraams or before them

I assume this F-15A is just meant to close a gap between F-4E and spamraams.

yeah, still pretty disappointing though. we’ll have to deal with ers for the time being.

i wonder how they’ll handle fox 3s for soviets. the r77 outperformed the early amraam, so im guess they’ll only add it to the 29 considering the flanker we have in game never carried them, and have the eagle have quantity over quality

here are my results, testing every 5,000feet, clean airframe, min fuel, full ab, in test flight so conditions should be repeatable and close to standard atmosphere.

  tested on dev server    ........  reference

50,000’ @ 1210kt (2.16M) … < 1434kt (2.5M)
45,000’ @ 1307kt (2.32M) … < 1434kt (2.5M)
40,000’ @ 1336kt (2.35M) … < 1375kt
35,000’ @ 1332kt (2.3M) … > 1290kt
30,000’ @ 1202kt (2.04M) … ~ 1200kt
25,000’ @ 1094kt (1.82M) … ~ 1100kt
20,000’ @ 984kt (1.6M) … < 1030kt
15,000’ @ 927kt (1.48M) … < 950kt
10,000’ @ 863kt (1.35M) … < 900kt
5,000’ @ 822kt (1.26M) … < 840 kt
S.L. @ 787kt (1.19M) … < 800kt

Looks like the manual at 10,000 and 40,000 feet for a little bit less weight.
