Mach 1.5 @25k feet at MIL power?


Recommended Posts

Hi, with a clean F-14B and standard day (15 degrees, no wind), I can reach mach 1.5 at MIL. 

That is, I never had to engage the A/B, just MIL power all the way to Mach 1.5. 

 

I know the F-14B could supercruise just above Mach 1, but Mach 1.5? That's F-22-like supercruise. 

So I'm reporting this as a bug.

@IronMike Are you guys aware of this?

Could you please give more details about your flight ? What altitude ? Was it in a dive ?

No loadout I assume ? 

 

Still very surprising. 

Kind regards,

Vince

I can confirm. Tested level flight in clean F-14B (no gun ammunition, no stores, full internal fuel) @MIL power, 25k ft, 15 deg. C day and no wind, it slowly gets to almost M1.5 - the fuel is @13.0 then.

And specially for @Donut - same test with empty bags - it gets to M1.1 only.

 

Edit: this is just to confirm the numbers - I don't know about real aircraft performance

From wikipedia:

Quote

Supercruise is sustained supersonic flight of a supersonic aircraft with a useful cargo, passenger, or weapons load without using afterburner (also known as "reheat").

 

Many 4th generation fighter jets are technically capable of supercruise, but only at high altitudes and in a clean configuration. For an aircraft to be deemed capable of true supercruise, it must be able to carry a normal load for an extended distance without diving or using an afterburner. Optimally, qualifying for "true supercruise" would involve demonstrating the ability with a combat load at low to medium altitudes; being able to break Mach 1 without afterburner does not in itself show supercruise ability.

Yeah, not too surprising while clean, but no way of telling without HB acknowledgment on this...they seem to have disappeared lately though from posts concerning the FM.

 

I tested this as well and get the same results.  As draconus pointed out, I find it interesting that the drop tanks seem to have an appropriate drag effect here, while as in my test from another post, they don't.

In a clean configuration its not surprising the B can supercruise once you get up to 25k, although whether 1.5 is realistic I'm not sure

Probably not. But FM changes are in the making, so we'll need to wait.

Current modules:

FC3, Mirage 2000C, Harrier AV-8B NA, F-5, AJS-37 Viggen, F-14B, Combined Arms, F/A-18C, F-16C, MiG-19P, F-86, FW-190A, Spitfire Mk IX, UH-1 Huey, Su-25, P-51PD, Caucasus map, Nevada map, Persian Gulf map......ah yes, forgot the Super Carrier! Shows you how often i fly these days....

 

Modules in waiting: F-14A, MiG-23, F-4U, F-8, Falklands Map

 

 

Wish list: South East Asia map, F-4J/N, A-6, F-15A/C, Su-27, Sea Harrier FRS.1, Mirage III, MiG-17.
