Guided air close combat missile R-73

Rocket small radius acts "air-to-air." Creating a rocket begins with the decision of the Council of Ministers of the Union of Russian middle of 1974. Work on the rocket charge OKB-4 under the control of M.Binovata.

Create the latest rocket was a continuation of work on the K-60 missile. Initially, the newcomer is not rocket used on full power seeker and had a gas-dynamic control. In the upcoming planned to use the modifed head missiles K-60. But still it was decided to immediately create a missile with all-aspect seeker "Lighthouse" from the plant "Arsenal". In addition, at a meeting decided to design a rocket in a modern aerodynamic style by changing its size. After retiring from life M.Bisnovata changed it in the post G.Hohlov.

Tests seeker begin in 1978. They were held at the LL-124 (flying laboratory). First tests of prototypes newest rocket start in 1979. During ground tests practiced gas dynamic properties. A little later, in 1979, a full-scale factory tests, in which the carrier aircraft MiG-23ML, tail number 123, having made about 10 ka flights with missiles on board, made a three-run K-73.

1980. The first time a missile K-73 shot down by educational goal — the MiG-17. 1981. To participate in the testing entice new MiG-29, tail number 9-19. During the first tests of the K-73 missile, fired from his side, struck a training goal — the MiG-21ml.

1981-1982 year. There is a transfer of development of K-73 Design Bureau "Vympel", the work led G.Sokolovsky. It remained to them until 1994. "Vympel" modified the rocket and it is taken into service under the name of P-73 in 1984. In series production of the R-73 RMD-1 come in 1987. A subsequent version of the R-73 RMD-2 has the ability to reverse the start and can do the functions of aviation missile class "air-to-air." Development since 1994, manages Yu.Zaharov.

The base version of the missile K-73 received the title of RMD-1, and in 1983 it went into mass creation. The main producer — Tbilisi aircraft plant, creating additional missiles Capital Works "Communar." At the main plant until the end of series production (1992) was created six thousand units of R-73. Similarly, it is not clear, but may be in pilot production of "Vympel" made the R-73, both for export and for the needs of the Russian Air Force. Until nedavneshnego different time of maintenance and repair F-73 spent 711 aircraft factory, located in the town of Boris Gleb.

Arrangement and design of the R-73
Standard missile is made with the introduction of wind a "duck." In front of the installed sensors and slide attack. There's also made aerodynamic control surfaces and Destabilizers. At the rear wing made, provided the ailerons. R-73 uses 4 sections gas dynamic steering wheels.

R-73 is composed of the following modules:
1. Seeker with aggregates of aerodynamics;
2. Autopilot, fuse contact type and control;
3. The gas generator;
4. Warhead and PIM;
5. Solid-propellant rocket engine.

The body is made of aluminum alloy, and the motor housing — steel. The compartments are connected by means of bayonets, the last — the flanges. Managers are working on derivatives of the gas generator. In the stern hull derivatives act on special channels machined on the outside of the housing. Control of a rocket produces autopilot and seeker. Ailerons produce stabilized rockets from the slope.

Seeker "Lighthouse" created Kiev now, "Arsenal", in which implemented new methods and solutions for noise control. In the R-73 RMD-2 is already installed GOS, which owns the overcharge protection against interference with frisky reprogrammable algorithms. Increased ability of low-flying targets.

Solid-propellant rocket engine has a single mode of operation, 785 kilograms of thrust controlled. Options were rockets, which were equipped swivel nozzle, which made gains traction in 5 percent.

Carriers aircraft such as the Su-27, MiG-29 can work with missiles helmet-mounted target designation means of implementation of the "gap", thus enhancing the ability of the media.

Warhead carrier battle rods PIM installed inside. To engage targets used uranium rods, the total weight of 2.5 kilograms. Used to undermine the proximity fuse. On the main mass of the fired missiles mounted radar fuze "Merlin" on later versions of the rocket fuse installed optical laser type "Amber". The main attack range combat rods about 3.5 meters.

As launchers used P-72/P-72-1D/P-72-1BD2 another name APU-73-1/APU-73-1D. By helicopter-carriers used APU-62-1M. Suspension missiles on launchers by using drags. Last modified RVV-MD, demonstrated at exhibitions mounted on launchers "P-72-1D/P-72-1BD2." The rocket leaves the factory in a sealed cover, to wood capping.

Known versions:
