    mrbm s-2 The decision to create its own strategic nuclear missile forces land-based decision of the Council of Defense of the Republic of France in February 1962, was called as a delay in the construction of its own fleet SSBNs armed with SLBMs French production, and understandable in the light of the so-called French politics. "Nuclear nationalism 'desire to have their own diverse stable nuclear deterrent. According to the decision by the end of 1971 on the territory of the French Republic planned to deploy the first silos (silos) with high resistance to the effects of a nuclear explosion (PFYAV), which planned to place the solid BRSD equipped with monobloc nuclear warhead. Shortly after the beginning of the deployment was planned to increase the number of simultaneously standing on alert BRSD to 54 pieces. This component of the French strategic nuclear forces was organizationally obey the command of the Air Force (similar to the U.S. Air Force ICBM SAH) and applied, due to the relatively low accuracy and power of a nuclear warhead to defeat large, relatively poorly protected, area political, economic and military purposes on the territory of the Warsaw Pact countries and especially the USSR. French economy in the first half of the 60s was on the rise, thus constantly and large-scale financial support research and the creation of the initial key systems, the most critical period of development of the whole program.

    By the time a formal decision on the establishment of the French MRBM rocket scientists already have some experience in creating small solid-fuel rockets are tested at the site Hammagir in Algeria. To create the first French BRSD was created French National Laboratory ballistic and aerodynamic research, combined efforts of leading French aerospace companies of the time, especially "Aerospatiale", "Nord Aviacion" and "Sud Aviacion." Warhead designs and manufactures the CEA - the civilian Atomic Energy Commission.

    In 1966, the landfill Bicarosse flight tests began a two-stage ballistic missile S-112 (12.5 m long, 1.5 m in diameter and weighing 25 tons). S-112 was the first French rocket launch which was carried out of the mine. Her in 1967 was followed by a more advanced missile S-01. Finally, in December 1968 the first prototype began testing a medium-range missiles, the designation S-02. On his finishing to level the series model, dubbed S-2, and joint flight tests all combat missile system took more than four years and 13 starts. To carry out the entire complex of flight tests on the Bay of Biscay Atlantic was built Bicarosse landfill, used for testing missiles for various purposes by the moment.

    discussion about the amount needed missiles began almost immediately after the decision to deploy them to production. By April 1965 the number of the planned deployment of a missile was reduced to 27, which appear to be associated with increasing both financial and political problems, and the complexity of the simultaneous production of relatively large amounts of MRBM and SLBMs. Construction of silos and the necessary infrastructure for the Plateau d'Albion began in 1967, but in December of the following year it was decided to reduce the number of deployed missiles simultaneously to 18. Instead it was soon instructed to start developmental and research work on creating missiles with improved performance characteristics, which was later known as S-3. Deployment of the first group BRSD (9 missiles) created as part of a strategic missile brigades 05,200 Air Force French Republic began in August 1971. Deployment of the next group of 9 missiles began in April 1972. The first combat-start a new series from the landfill BRSD Biscarrosse held in September 1973.

    BRSD S-2 was in service with the French Air Force relatively short time - in April 1978 the first group of 05,200 Brigade re-start the more advanced S-3 MRBM. Finally, S-2 missile was removed from service in the summer of 1980. Just before removing the missiles from service was made 6 combat training launches serial BRSD.

    Composition

    mrbm s-2 S-2 rocket was performed two-stage scheme inline degrees. Way to the launching of the silos - with gas-dynamic engine is started within the first stage of the mine. Cases both propulsion speed (SEP and SEP 902 903, respectively) were made of the rocket special light and heat resisting steel Z2-NKTD thickness of the housing 18 to 8 mm. Body was covered with a special thermal barrier coating, defending against missile hot gases during launch, aerodynamic heating and the effect PFYAV. To create control efforts to control the missile in the boost phase trajectory pitch, roll and yaw at each stage were applied four divergent nozzle of high-and heat-resistant alloy. To increase the resistance missiles in the boost phase of flight in the first stage had four fixed stabilizer. Each stage was equipped with a system of compulsory liquidation in the case of violations of the flight program. A method of separating sustainer stages - cold mortar due to pressurization mezhstupennogo space with a special gas generator and transverse division connection speed by the elongated conical charge. Method for separating the head from the second part of the sustainer stage after reaching the desired ballistic trajectory has been a traditional ballistic missile - MS office from the second stage using pirozamkov response, and then opening protivotyagi nozzles in the second stage, that ceased burning charge sustainer engine, brakes and away stage it away from the head of the breakaway.

    Each

    BRSD housed in individual silo launcher single launch (MSE OS), closing the massive concrete lid sliding weight of 140 tonnes, which opened before starting using the powder charge (see diagram). Through the application of design silos OS special steels and concrete varieties, systems of general and local depreciation accommodation durable rocks at a great distance from each other, making multiple copies of communications and control systems, the overall stability of the complex to PFYAV was, according to experts, it is very high for the time. According to their estimates, in-class set of S-2 held first place in the resistance PFYAV even leaving behind a number of U.S. and Soviet ICBM complexes. All silos OS merged into 2 groups of 9 missiles each. Each group was ruled out of the KP is in the rocks at great depths and provided an effective system of depreciation. Were repeatedly duplicated system of communication with each silo, and with higher levels of government. Rockets were in high willingness to use - start time of full combat readiness should not exceed one minute. Technical inspection and launch rockets carried out remotely. Clock duty in the CP carried change of 2 officers.

    The rocket was set inertial control system, produced in France, located in the special instrument compartment comprising the second stage. CWE when firing at maximum range (3,000 km) is 1 km. Complex decoys are not equipped with a rocket. The missile was equipped with monobloc nuclear warhead warhead MR-31 capacity of 120 kt with the actual warhead weighing 700 kg. MS had two options to undermine - and air contact. Warhead had ablative heat shield type. Not rocket fairing was completed. According to experts, the stability of the warhead to action PFYAV was because of design features pretty low. First warheads were released in 1970 and was decommissioned in June 1980.
