Yeah they designed the Foxhound to fix that. The Foxbat's construction didn't translate well to performance down where the air is thick, it's not even supersonic at sea level.The Foxbat was fast but was not very maneuvarable.
vanir said:Back when the US had cancelled the YF-12A Mach 3.2 interceptor programme due to ridiculous costs and gone with the F-15 as the Air Force front line of defence (which was ridiculously expensive anyway), it could not be understood how the Soviets had managed to develope such performance in a mass produced interceptor.The Foxbat was fast but was not very maneuvarable.
vanir said:On the battlefield however, a MiG-31M is easily one of the most dangerous aircraft you can come across today at any altitude and under any conditions. In 1990 it was probably the most powerful aircraft in service in the world.
We know it as the two-seat Foxhound and it has to be one of the finest performance pieces of the 20th century, combining better overall performance than an Eagle with the weapons system of a Tomcat.

Several versions of why the Foxbat was initially designed exist. I like the one adopted by Jane's Information Group, which I've always found to be among the most reliable technical sources available anywhere, in some cases I trust them more than I do official military release information.FLYBOYJ said:vanir said:The Foxbat was probably one of the key reasons the XB and YB-70 Valkyries were cancelled.
You got it Backwards - The Mig-25 was developed to counter the XB-70. That was mentioned several times in the book "MIG PILOT." The XB-70 was cancelled because of Soviet SAM development (1964, the program ended several years later when an F-104 collided with one of the prototypes east of Edwards AFB, California). The USAF changed it's stategic strike doctrine and developed low-level tactics and eventually coupled that with Stealth technology.......
Design started 1959 as Ye-155P supersonic high-altitude interceptor to counter all potential threats, from cruise missiles to A-11 (SR-71A reconnaissance aircraft) under US development; programme launched officially February 1962.
(Russian air forces): MiG-25RB (Mikoyan Type 02B; `Foxbat-B'): Single-seat high-altitude reconnaissance-bomber, derived from Ye-155R-1 prototype; production began as MiG-25R (Type 02), for reconnaissance only, in 1969; bombing capability added to redesignated RB in 1970; able to fly long distances at cruising speed of Mach 2.35, maximum speed of Mach 2.83 with full bomb load.
The inconsistency I've highlighted is to show the somewhat questionable credibility in the source.The MiG-25 high altitude, high speed interceptor was initially developed to counter the Mach 3 XB-70 Valkyrie bomber under development in the US in the late 1950s and early 1960s.
Although the XB-70 as a bomber was cancelled in 1961, work on the new high speed interceptor and reconnaissance platform continued.
Initial 'Foxbat' production was of the MiG-25P interceptor. Service entry was in 1973.
The MiG-25 was originally designed to counter the A-11, not the B-70 as we all believed.
And more about the Foxbat's interception performance.The MiG-25 that was clocked at Mach 3.2 by the Israelis achieved this speed while running from an intercepting F-4 (which can barely manage Mach 2 on a good day--before running out of fuel). Upon landing, both engines in the MiG had to be replaced.
Mach 2.83 is a theoretical stability limit on the airframe (which has been safely exceeded on numerous occasions by test pilots). At speeds greater than Mach 2.6 however, throttle control must be precise to keep the engines from overspeeding.
The F-16 can just barely squeak past Mach 2.0 with a pair of wingtip sidewinders. The F-14 can only manage Mach 1.81. And the mighty Eagle is only good for Mach 1.78 (Mach 2.5 clean). The Foxbat can outclimb all of these fighters by a healthy margin, and has a mauch better supersonic endurance than the best Western fighter (F-22 notwithstanding).

plan_D said:Favourite post-war aircraft; the English Electric Lightning. From a 1947 design it was the greatest interceptor of the Cold War and served until 1989 in the RAF.
vanir said:If the project had continued it would have been only as a transport/reconnaissance vehicle, as its strategic capabilities were obviously clearly outclassed by the Foxbat and YF-12A designs. It was a bit expensive for such a secondary role and its development value had been all but superceded.
vanir said:I also found more information about Foxbats doing better than Mach 3 speeds at the same aviation.ru MiG 25 website.
