RT-23UTTKh Selina-2 - Road Mobile
The government decree on the development of a single missile for mine, railroad and ground-based basing took place on August 9, 1983. The development of the project of a combat ground missile complex with a three-stage solid-fuel intercontinental ballistic missile with MIRVN was launched at the Yuzhnoye Design Bureau under the leadership of Vladimir Utkin. The project foresaw placing an ICBM launcher on a MAZ-7906 twelve-axle wheel tractor. The twelve-axle missile carrier was to consist of two articulated six-axle tractors. It was assumed that a three-stage ICBM articulated from two blocks would be placed on the launcher. The docking of the blocks was to be performed before launching the missile.
Work in the Soviet Union to create a mobile ground missile complex with solid-propellant ICBMs began in the late 1950s. By the late 1960s, light solid-propellant ICBMs with a starting mass of up to 50 tons were used for placement on ground mobile launchers. From the beginning of the 1970s, work continued on the creation of a complex with the RT-23 rocket with a mass of 80-90 tons, initially with monoblock combat equipment. Then with MIRV warheads, the mass of the rocket increased to 105 tons. It was decided in the complex to have several distributed stationary launchers for each missile and transport them to covertly missiles with ground conveyors.
In the first studies on the creation of a vehicle for the RT-23 rocket, a caterpillar articulated chassis was considered. In 1976 KB-3 of the Kirov plant under the leadership of the chief designer NS Popov created prototypes of the caterpillar articulated chassis "object 829", consisting of four sections, based on the support rollers and tracks of the T-80 tank. The weight of this chassis was about 200 tons. Because of the complexity of the operation of such a chassis, it was abandoned and work began to create wheeled vehicles.
As part of the rocket and space work in 1979, the Resolution of the Central Committee of the CPSU and the Council of Ministers of the USSR was issued for the development by the MAZ of a wheeled special conveyor with the carrying capacity of 220 tons. With the transition of the military railway missile and silo complexes to the upgraded rocket RT-23UTTX, RT-23UTTX (15Zh62) began to be deployed in the ground complex.
The Celina-2 rocket was similar to the RT-23UTTX rocket, because according to the Decree of the Central Committee of the CPSU and the Council of Ministers of the USSR of August 9, 1983, the development of missile systems with the unified R?-23UTTKh "Molodets" missile was in three types of basing: combat railway; movable ground and silo. The missile used the main technical solutions used on the rocket 15Zh52. The lead organization for the mobile ground missile "Celena-2" was the Moscow Institute of Heat Engineering (MIT) headed by AD Nadiradze. The development of the missile for the Celena-2 complex remained the Yuzhnoye Design Bureau, under general designer VF Utkin.
In 1983, the Minsk Automobile Plant (MAZ) produced a prototype wheeled special conveyor "7904", which in the same year was sent to NIIP-5 (Baikonur) for testing. The machine was intended for use in the Energia-Buran rocket and space system for delivery to the space center of the spent side rocket stages of the launch vehicle, and as a chassis for the missile complex. The chassis of the "7904", with a width of 6.8 meters, was installed engines with a capacity of 1500 hp, two in parallel coupled hydromechanical transmissions, 12 driving wheels with a diameter of 3 meters. Control was carried out by turning front and rear wheels.
The development of the project was terminated.
