A-12 "Oxcart" (SR-71) and the strange tale about this plane

SR-71 was the fastest aircraft in the world, and it had the capacity to fly at speed over 3600 kilometers per hour. The program was also known as A-12 "Oxcart", and the name of this system was selected for covering the top-secret spy plane, by claiming that is new attack plane. This aircraft had extreme high speed, and some of them were lost in accidents. One of the reasons or the biggest reason for terminating this program was that the CIA afraid that the motor technology what was used in this plane got into hands of the communist block if one of those planes would get the motor damage during the mission.



There were explosives in those planes, that if it would go too low, the explosives were destroyed the motors and other important parts of that plane, and some of the destroyed planes were destroyed in the tests, where those self-destruction mechanisms were tested because CIA afraid that KGB might slip their agent in the service crew, and that person could remove the explosives. If the pilot of that plane could also want to take the plane to the hands of Soviets, that would be the catastrophic thing. And destroying the planes in those security screens is very expensive.



This is, of course, one reason for the price of that mission, but for the high costs of the airplanes were many other reasons Actually, SR-71 (A-12) were two planes, the airborne refueling plane, and the recon plane, and every one of those aircraft used unique fuels, and they had the unique ventilation system, what rises the costs of that program. Another means the plane, what was used in Air-Force, and another one means the planes, what was made for CIA, by using materials, what were brought by passing the bookkeeping, and also those planes had special numbers, what were not public. CIA used those planes for deep penetrating missions in the Soviet airspace. The funny thing about those planes is, that Titanium, what was used for them was bought from the Soviet Union. This information was delivered in some TV-document of that project.


Also, CIA is suspected to transfer money by this project for "black budget" aircraft and weapon projects, and this is why the costs of this program were extremely high. But there is a tale, that some of this fastest man-made aircraft had the capacity to carry bombs and missiles. The rumor claims that SAC planned to install nuclear weapons to the internal bomb bay of this plane. That's the reason, why the A-12 had the letter "A" in the name, but I don't know does the SR-71's attack version existed.


There are rumors that there were three types of this aircraft. YF-12, what was planned to be an ultra-fast jet fighter, A-12 what was or is an attack version and SR-71, what is the reconnaissance version of the worlds fastest aircraft. The YF-12 was code-name for this project sometimes, and the nuclear weapons could be the good reason for keeping persons out of the areas, where this plane kept for service and other purposes, but as we know, the SR-71 is real, but other variants of this plane are only rumors.


Maybe they were stored in AREA-51 or destroyed when the program was terminated. But as we know, there are many secrets in that place, and maybe this aircraft still flies in the top-secret world of intelligence, under the project, what code-name have not been mentioned. The reason, why the SR-71 was mentioned as "grey project", means that those aircraft were so expensive. The production of those planes outside the official bookkeeping was also making suspects, that there were many things, what somebody didn't want that was not known in public.

The SR-72 project the fastest air using aircraft in the world


Picture 1

Kimmo Huosionmaa

Lockheed-Martin Corporation has created the new concept for ultrafast aircraft what will succeed the SR-71 "Blackbird". The SR-71 was the fastest aircraft and it bases the technology, what was created in 1960's. The body of the aircraft was made of the titanium, and it has capable of flight Mach 3,2 to Mach 3,5. The maximum speed depends on the calibration and wealth of the jet engines, what were under very high pressure and temperature. And those extremely powerful jet engines were corrosion very fast, and if the motor was not thin, the maximum speed was decreased the little bit. But when the SR-71 program was canceled in 1998 there were not succeeded of that marvelous plane. And the rumors started to grow.


There was mentioned some airplanes what had code-named "Aurora" and there is actually no knowledge what does that world mean. In some discussions that were mentioned to mean the ramjet or scramjet motors or some other exotic propulsion systems like PDWS (Pulse Detonation Wave Systems". The PDWS is actually same kind of flap engine, what is used in German V-1 (Fi-103) flying bomb, In that engine has flap system, what allows the pressure of the fuel rise high, and then the ignition lightning will be given to the fuel and oxygen combination.


When the flaps what are in the front of the engine are open, the motor will suck the air, and then the frontal flaps will be closed, and the flaps of the exhaust tubes will be opened, and same time the ignition spark will be given to the motor, and then the exhaust gas would be given the speed of the vehicle. This system allowed the launch of the V-1 bombs from the ramps without the rocket. The frontal flaps were closed, and then the fuel was injected into the combustion chamber, and then the fuel was sparked. The flap ramjet works in the same way, and only the shape of the motor is changed as the ramjet or scramjet motor.
(Picture 2)


When the speed of the airplane will rise high enough, both flaps can be stayed open, and then them motor works like normal ramjet motor. The flap systems allow to use ramjets in the low speed, and another way is, of course, use normal jet motors to accelerate the speed of the airplane and start the normal ramjets after the speed was increased high enough, that the ramjets can begin to operate, and normally that speed is about 900 kilometres per hour. The SR-72 is not like normal recon plane.


It would have the capacity for Mach-6, and it can fly any point of the earth in one hour. The Business Insider magazine will give the information, that SR-72 has not mentioned using only in the reconnaissance missions. That plane could use the smart bombs like Precision guide Nuclear Weapons, GBU-32 or Maverick and Hellfire missiles in its missions. Also, it can deliver MAV:s to the operational area. The plane would be unmanned and it might use the same kind of computer systems than "Predator-UCAV's" uses, and there might have the same kind of missions than those official UCAV's have.


But the SR-72 has more capacity to make the strikes than slower "Predators". In some scenarios, those "Super Predators" can be used against all targets what the conventional airplanes can be used. There might be many sizes of those very fast aircraft, and they can be carry also MAV:s (Miniature Aerial Vehicles) in the operational zone. So they can use also as the assassination missions what have targeted well-known terrorists and other criminals. Those super fast SR-72 aircraft can conduct the USAF global strike capacity, what will now get the change to take the control of the hostage situations.
