58 years ago, on November 4, 1968, the first launch of the first Soviet solid-fuel intercontinental missile RT-2 took place. Work on RT-2 began in accordance with the decision of the Central Committee of the CPSU and the Council of Ministers of the USSR No. 1291-570 of November 20, 1959. She became for OKB-1 S.P. Korolev is the second stage of the development of a solid-fuel ICBM. It was based on the RT-1 missile, which had insufficient flight range and a high accident rate, and was therefore not accepted into service. To test the third stage of the RT-2, a version of the rocket was created, known as the RT-1-63. The preliminary design of the RT-2 rocket was developed in 1963. The rocket envisioned the use of two types of warheads. The first type, weighing 500 kg, allows launches to a range of 10-12 thousand km. The second type of warhead, weighing 1400 kg, can be launched to a range of 4-5 thousand km. The rocket was launched from a protected silo and was ready for launch in 3-5 minutes. RT-2 was tested in two stages. The first stage (7 successful launches) took place at the Kapustin Yar training ground. Between October 3, 1966 and November 4, 1968, the second phase of testing took place at the Plastek test site. Of the 25 launches, 16 were successful. This was deemed sufficient for the RT-2 to be adopted by the Strategic Missile Forces, which happened on December 18, 1968. The rocket was produced by Perm plant #172. In 1972, an improved version of the missile, the R-2P, was put into service. Missiles of this type were in service until 1994.
