The MiG-25 and MiG-31



The MiG-25 and MiG-31

The Russian MiG-25 (1) "Foxbat" and MiG-31(2) "Foxhound" fighters are officially the fastest combat aircraft in the world, and sometimes the aviation specialists have created the question, why those aircraft have been developed. The answer might be that the Russian planned to use them also in ASAT missions, as I have written before. And maybe they are planned to use the supersonic pressure air cone for terminating ground forces. 

But there is still the question, are those aircraft, especially MiG-25 created only for one purpose, shoot down SR-71 "Blackbirds"?(3) Could some aircraft be so important, that there is created the own aircraft type against those aircraft? The MiG-25 is almost as fast as SR-71 "Blackbird", and the shootdown should be easy by using the AA-6 "Acrid" missiles, which were specially made for MiG-25 and later those missiles were installed also under the wing of MiG-31(4). 

Or they were not installed in other aircraft. Sometimes there is claiming that some supersonic jet fighters are created for carrying supersonic weapons and in fact, the normal aerial launched rockets that are shot from MiG-25 style Mach 3 interceptor would travel across the air by speed Mach 3 plus the speed of rocket itself. That means that the fast aircraft would be a terrifying weapon itself, even it is equipped with conventional missiles and rockets. But when we are thinking about SR-71 "Blackbird" there is no reported case, that the craft is ever shot down. In other things like accidents those aircraft have been destroyed, but there are reported five countries (5), what has been shot missiles against SR-71. 

And only one case has been highlighted in those cases. The case, where North Korea has shot missile against that spy plane. Why this case is only, what has been told to publicity? Why other cases, where the SR-71 has been targeted to fire are kept a secret? Is MiG-25 or MiG-31 ever flown, when SR-71 has been flown in Russian airspace? The thing is that "Operation Overflight" was and still is top secret, and the missions of SR-71 were made under the ultimate secrecy. 

But why those attempts to shoot that plane down has ever reported by Russia or its predecessor Soviet Union? When the SR-71 finally retired, there have been rumors, that it has been replaced by some extreme secret and super-fast aircraft, which is known as "Aurora", what is claimed to be marked as SR-72(7). But when we are thinking about this thing the retirement of SR-71 happened finally in 1999, when NASA retired its pieces of that aircraft. The real reason probably was that this technology, which made that aircraft ultimate recon plane was not wanted to let to the hands of Russians. 

And that means that "Aurora" would be 20 years old concept, and the question is, why that aircraft has not been published? When we are thinking about Lockheed-Martin "Falcon" (8) the "Aurora", that claimed to have the capacity of Mach 5, is a moped in the comparison between the Mach 8 capable "Falcon", and the "Hyper X" or X-43 (9) speed record in the atmosphere is Mach 10 that makes the hiding "Aurora" somehow interesting. What is hiding behind that code word?

This is what people don't want you to know about ultra-fast aircraft




This is what people don't want you to know about ultra-fast aircraft

When we are thinking about the aircraft like MiG-25 (1) and MiG-31(2), which are the extreme fast interceptors, we might think that those aircraft are somehow harmless. The thing is that the ultimate fast speed would allow them to fly to the outer atmosphere, and they are capable to destroy the low-orbiting satellites. But there are also rumors, that in some of those aircraft robot versions would be installed the nuclear bombs, and they would be used as the cruise missiles, what can return to the base if they are no need to use. 

And sometimes we might wonder, why they are mentioned in the list of the gunships?

Many people believe that effective attack aircraft would need a sophisticated weapon system for being dangerous, but this is not true if we would want to sweep away the entire enemy army. So have you ever heard the term "sonic boom"? The term means the conical pressure wall, which is forming if the aircraft is moving faster than sound. This means that when the aircraft would cross the sound barrier the air would not have time to go away from the front of the plane. That causes effect, where the air molecules are pushed away from the surface of the aircraft with the speed, which increases Mach 1. 

The thing is that the pressure wall would travel faster than the speed of sound, and that turns the air to the wall, which is called "shock wave". This term is taken from the explosives. The pressure impact of explosives causes the pressure wall, which travels in the air by the burning speed of the explosive. A nuclear weapon creates a pressure effect by increasing the temperature very fast at the point, where the explosion happens, and the expanding gas is the thing, that is called a shock wave. 

The thing is that if the aircraft, what travels by speed Mach 3, would fly very low, the pressure wall would be hard as steel, and that thing would cause terrible damages in the area, where that thing affects. But what if we would install loudspeakers to the nose of MIG-31 or MiG-25, which are the Mach 3 interceptors? That thing would cause the movement of the air molecules would get the speed of aircraft behind them, and this means that the pressure wall would travel 4000 kilometers per hour to the target. This is the reason, why the aircraft cannon is effective. 

 If the speed of the ammunition of the cannon in a stable position is 1000 kilometers per hour, would the aircraft cannon, what uses the same ammunition would be installed in the aircraft, what is flying 1500 km/h, the speed of ammunition will be 2500 km/h. This makes the aircraft cannons more effective than the similar cannons, which is installed on a stable platform. And if the aircraft is flying speed of Mach 3 it can make the ballistic jump, which makes it capable to destroy low orbiting satellites.
