Had a quick lunchtime fly, followed the cold start tutorial mission and took off.  Anyway, clean jet, with pylons, FL280, MIL power, M1.03.  

Is this correct?

Clean jet?

Have you check the bindings? I had to adjust the afterburner cutoff level cause I was actually in afterburner with the detent of my Virpil Cm3.

Although M1.03 should be possible in a clean jet at angels 28 with those powerfuls PW229. Hornet and viper also supercruise when clean and medium fuel load.

Clean jet with pylons, 93% thrust, no AB.  I could believe a fully-slick jet might be able to do it under certain conditions, but surprised it will with pylons on.

The engines seem to be quite powerful, and drag lower than I expected. I was able to fly Mach 1.0 in mil as well.
For comparison, the Hornet will do 1.01 with pylons and 1.1 clean, so as far as I understand any 4th gen fighter can break M 1.0 in military power.

Breaking is one thing, sustaining another.  I could have sat there in the cons all day at a steady M1.03.

Most can with lower fuel state.

How so? When the engines manage to shove the jet beyond M 1.0 without afterburner, why would they then not be able to sustain it?

Anyway, as far as I'm aware, supercruise is not unique to jets like the F-22 that get that feature advertised a lot. They can just do it with combat loads, whereas 4th gen jets may be able to supercruise with clean or pylons only configurations and with less than full fuel.

Can the F-15E do that under the given circumstances? I don't know. But it sounds plausible to me.

It was said in response to Raven's statement that "any 4th gen fighter can break M 1.0 in military power".  Of course they can, but not all can in level cruise.  Cracking M1 in a dive at MIL power is very different, eventually you will reach denser air or denser ground.  Or even accelerating through the barrier and then reducing to MIL, you are technically in supercruise at that point, but will be decelerating.  

All I was wondering was if it was a known ability of the Strike Eagle with pylons fitted to be able to do it.  I imagine if so, then it would be plausible with CFT fitted AMRAMMs too.

Yes, it is correct.  That is also not considered super-cruise by most standards.

I wonder if the Mach speed is out of calibration? as i was at angels 20, also mil cruise, and hud said M1.013 (or something like that), but when i went to fly by, i didnt get the sonic boom, and external view from the front i could still hear the engines. Also that was with stores, in the included mission where you need to find a business jet "stranded ship"

I did it with a load out... 8x GBU-12s, 3 bags, 10k lbs fuel total)  no way it should do that.  Level flight Ang 32, mil power.  Engines or drag definitely need some work

The F-22 sustains 1.7-1.8, that's 'supercruise'.   Sustaining 1.03 while draining your fuel like crazy compared to say 0.85-0.95 isn't exactly some sort of accomplishment IMHO, just technically supercruise.

Agree, it’s more like high drag “transonic cruise”, eating fuel. Super cruise should be above transonic speeds, like more than 1.2, where drag decreases. 

What is the official definition of super cruise?

Most definitions consider it to be 1.2 and above, or close to.

Literally yes, but 1.03 isn't of real value.  It demonstrates that the engines have oomph, sure, but all you're doing is flying inefficiently.   M1.2+ without burners is more of an accomplishment, and 1.5+ replaces flat-dash intercept regimes that were AB-only territory.  The short of it that you can go further faster on the same tank of gas.

If you want to go far though, you'll still be travelling subsonic in most cases (ie. the cases where you're not flying a Raptor, and even then I don't know what the efficiency looks like)

Wait till the Eurofighter is released that can supercruice at M1.5

The most credible source I've heard is that supercruise in the Eurofighter is M1.2-1.3ish with a normal A2A loadout, which is 4MRM-2SRM, if that figure is with 2 bags I'm not sure.

It is difficult to believe for me that M1.5 is other than a clean jet.

6 120s, 2 9Ms, full internal fuel, no tanks. I found I was able to fly at M1.0 somewhere around 20-30k. Fuel is obviously not full since I had to takeoff, climb, and accelerate to that speed. 

 

So I am pretty sure you can supercruise with a clean jet.

We are talking about clean jets.
