If you can find a picture with a rear view you can see that the booster is replaced by an extended rear fuel tank with a rounded end.

It is apparently possible to carry 5 Kh-59MKs on one Su-27. Not sure on which pylons though!

Early version:

Here’s air launched Kh-41 Moskit flight profiles.

A model which might have been part of the 701 (MDP) program?

Not quite- it was designed for economic supersonic AND subsonic flight. My guess is it had a variable-cycle turbofan like the AL-41F which could reduce bypass air practically turning it into a turbojet but also run efficiently at subsonic speeds.

For border patrolling, it could fly immense distances at subsonic speeds. If it was intercepting a target, it could fly as fast as possible.

Mach 2.0-2.3 sustained is as fast as you can go without needing exotic solutions, so its a sensible approach.

Distiller yes, I made a mistake. 701 was the interceptor while 701P was the passenger version. The drawings date to 1993 when they tried to promote the passenger derivative. The drawing Distiller posted is Piotr Butowski’s sketch drawing, which I think is older, but maybe PiBu can comment on that?

Coach, don’t expect it to be doing any high alpha manouvres…

It was a pure interceptor- fly fast, hit the bombers as far away from the USSR as possible b4 they launch their cruise missiles, engaging multiple bogeys at once with 300km-range AAMs.

Cruise speed was Mach 2+ (2300-2500km/hr) or Mach 0.9. Range at subsonic cruise was 11,000km and range at supersonic was 7,000km, though these figures are probably for the passenger jet version they give you some idea…

Armed with internal R-37 type missiles and a large phased-array radar, it would have been a formidable interceptor, though probably just too ambitious, expensive and just plain HUGE.

airwar.ru has a load of downloadable magazines here:

http://www.airwar.ru/other/bibl_j.html

The actual magazine is http://www.airwar.ru/other/aiv/aiv1994_01/index.html

Its a short article on 1.42 and 701P, it mentions in passing hypersonic recce aircraft “301” ( I know about) and “321” (not heard of).

I love the first one with the MiGs and Sukhois going overhead- it looks somehow menacing.

R95ТМ-300
Weight: 95kg
thrust: 350kg
sfc: 0.85

SFC *is* higher, but the fuel burn rate is lower than 36MT because of the lower thrust.

Erm, would that be the Libyan Mig-23MS with the MiG-21’s Sapfir-21 radar?

That was unable to look down *anywhere*, not just over the sea.

The MiG-23M/ML/MLD series had radars with had limited lookdown/shootdown capability, though I admit I’m not sure about over water. My suspicion is they were based off of AWG-10 technology in some way, so you’d think they might do…

Crobato is right, the N001 (Su-27) and N019 (MiG-29) use lots of common parts. N001 is really an N019 with a bigger antenna and a slightly better computer (twice the memory).

The Kh-59M flew 120km on the Soyuz engine that took the Kh-55 to 3000km..

possible, but it would need a new command pod- the existing guidance system has max command link range of 140km.

OK, you are correct it has been re-engined by the Lyulka-Saturn 36MT engine, but this is actually quoted as a ‘turbojet’ on their website.

http://www.npo-saturn.ru/production/avia/print/36mt.html

SFC: 0.71
Thrust: 450kg
Dry weight: 82kg
Max diameter: 330mm
length: 850mm

Russians don’t seem to distinguish the two when it is a low bypass turbofan- the Soyuz RDK-300 is called turbofan and turbojet in different sources.

It seems that the RDK-300 was made in the Ukraine, and the 36MT is an Russian replacement. It might be more fuel efficient as well, of course.

I can’t find any specs for the RDK-300 currently.

Perhaps the new engine works fine from launch conditions, and hence the discarding of the rocket booster stage?
