Information Wanted: Project 701

While doing research on the MiG-25, I came across a couple mentions of something called Project 701. Supposedly, it was a planned replacement for the MiG-31, and was being developed during the late 80s (but never was built). I've seen a couple different conceptual designs posted, of which this one seems the most plausible;

Although the planform is more than a bit odd for a design that was supposedly to have had low observability features (also, dorsal intakes on a fighter is wrong to me on a visceral level).

 

If anybody has any more information on this, please post it here.

I have it, but it's in a box at the moment. Thanks for page listing, though, I'll be sure to check it out.

Damn boxes

 

"In the late 1980s/early 1990s ANPK MiG began project studies of an ultra-long range high-altitude heavy interceptor designated izdeliye 701(or 70.1). This was regarded as a 21st-century successor to the MiG-31

 

The twin-engined aircraft was a two-seater, the crew comprised a pilot and a WSO seated side-by-side. It utilized a tailless-delta layout. The two afterburning turbofans - presumably Lyul'ka-Saturn AL-41Fs - rated at up to 15,800 kgp dry and 20,000 reheat were mounted on top of the rear fuselage in a common nacelle, breathing through a split intake with vertical airflow control ramps. The nose housed a powerful fire control radar - possibly the NIIP N014 developed for the Mikoyan MFI 5th gen fighter. The radar had twice the field of view, being able to detect targets with a high radar signature at up to 420 km away and track several dozen targets at once. A rear view radar(NIIP N012?) was to be installed in the rear fuselage, detecting targets with a 3-m^2 RCS at up to 50 km away; bomber-type targets would be detected at 100 km range. 

 

The interceptor was to have a normal take-off weight of approx. 48.5 tons and a max TOW of 70 tons, hence the designation "70.1". Its dimensions included an overall length of 30 to 31 m, a height of 7.2 m, and a wingspan of 19 to 19.5 m. The designed performance included a top speed of 2,500 km/h, a cruising speed of 2,100 km/h at 17,000 m and an effective range of 7,000 km in supersonic mode or 11,000 km in subsonic mode. The 701 would be armed with new models of long-range AAMs(R-37 and K-172) plus up to 4 R-73 short-range AAMs for self-defense. The K-172 missile with a max kill range of 400 km would allow the 701 to avoid engagement with the adversary's agile escort fighters. 

 

The program was mothballed in 1993 b/c of the RUssian MoD's budgetary restrictions. A civil version, the 70.1P supersonic business jet, was developed in parallel."

 

 

There are multiple models of the craft(some have canards others don't) and they seem to indicate an internal weapons bay. 

 

The 70.1P wasted approx $1.5 billion in MiG's R&D program.

over-budget, it never made it

That is a really screwy intake design.  I wonder what they were trying to accomplish with that.

 

That configuration would reduce radar cross section from ground-based radars, since they couldn't see the compressor blades... but it's an interceptor.  Why do you care if ground-based radar can see you?
