R-16 (6K64) and R-16U (6K64U) ICBM tech dossier:
R-16 development cooperation:
With the introduction of the R-16 ballistic missile, the collective led by Michael Yangel based in Dnepropetrovsk ended the monopoly held by Sergei Korolev's design bureau as the only supplier of the intercontinental ballistic missiles for the Soviet Army. The R-16 offered significant advantages to the Soviet military in comparison to the R-7, the first and only ICBM in the armaments of the Soviet strategic missile forces at the time.
Unlike the R-7, the R-16 would use storable propellants, which meant it could stay fueled for a long periods of time ready to fire. On top of that, the R-16 would be more compact than the overweight R-7, which would eventually allow deploying the new missile in underground silos. Finally, the R-16 would be equipped with autonomous flight control system, which would eliminate the need for a network of ground control stations used with R-7.
Yet, the R-16 flight record was preceded with the worst disaster in the history of rocketry, which claimed at least 92 lives.
Development of R-16 (8K64) and R-16U (8K64U) missiles
Yangel conceived R-16 as a logical step forward after successful development of R-12 and R-14 ballistic missiles, which both used storable propellants. The R-16, however, would be the first intercontinental missile using storable propellants. The mobile launch complex was originally considered for the missile deployment, but it was deemed too cumbersome. A MIRV version of the R-16 ICBM with three warheads was also under study. (74)
According to the official history of Yuzhnoe Design Bureau, the Soviet Council of Ministers approved the development of the R-16 ICBM on December 16, 1956. (23) At least two more decrees by the Council dealt with R-16 development: one on May 28, 1958 and another on May 13, 1959.
The preliminary design of the missile was completed by November 1957. (74) Both stages of the missile would equipped with main engines developed by the OKB-456 in Moscow and steering engines developed by OKB-586. The missile was made of aluminum and magnesium alloy with thin propellant tanks. The compressed air would pressurize the propellant tanks of the first stage, and atmospheric air the tanks of the second stage. Ground-based launch complex for the rocket was designated Sheksna-N and would include a pair of launch pads with common fueling and support systems.
An original ground-based launch complex for the R-16 would be built on the right (Eastern) flank of Tyuratam two surface pads at Site 41 and processing area at Site 42. The 2nd Test Directorate was formed in Tyuratam specifically for the R-16 operations.
In March 1960, under a directive from Deputy Chairman of Soviet of Ministers Dimitriy Ustinov, the R-16 developers contacted Leningrad-based TsKB-34 (KBSM) to study the possibility of development a silo-based launch complex for the R-16. On May 30, 1960, the government issued an official assignment for the development of the silo-based missile designated R-16U (8K64U). The silo-based complex for the missile was designated Sheksna-V. The specifics of the silo launch required changes in the design of the missile itself. For example, high-pressure nitrogen gas tanks were used to pressurize fuel tanks on both stages and the oxidizer tank on the second stage. Preliminary design of the silo complex was under review in March and October 1960. The blueprints of the complex were completed by March 1961.
In August 1960, the propulsion units of both stages fir the R-16 were tested in NIIKhimmash's Zagorsk facility.
The first launch of the R-16 missile was scheduled for the end of October 1960, before the celebration of the Bolshevik Revolution on November 7, however on October 24, a disaster on the launch pad killed at least 92 people, including some key figures in the R-16 development.
Getting back on their feet
At the time of the accident as many as five missiles were in production at Plant Number 586 in Dnepropetrovsk. Since OKB-586 chief designer Mikhail Yangel ended up in the hospital right after the accident, Vitaliy Chekhovskiy, a leading engineer at OKB-586, was put responsible for preparing the R-16 missiles for further tests.
Vladimir Sergeev, the department chief at NII-885 control system design bureau, accepted a proposal from Central Committee of CPSU to replace Boris Konoplev, who was killed in the R-16 accident, as a director of Kharkov-based OKB-692. At OKB-692, Sergeev led the upgrades of the R-16 flight-control system, which was primarily blamed for the disaster of October 24, 1960.
On January 1, 1961, the second R-16 missile (Production Number 3L-5T) arrived to Tyuratam. Its pre-launch processing started on January 4, 1961 at 08:00 in MIK-42 processing building. By that time, the chief of NII-4, the main research arm of the Ministry of Defense, Lt. General Andrei Illarionovich Sokolov officially replaced Nedelin as a chairman of State Commission overseeing R-16 testing. Sokolov established strict personal responsibility for all technical problems during the processing and introduced thorough documentation of all operations conducted in the assembly building. (27)
On January 27, 1961 at 8 a.m. the R-16 missile (Number 3L-5T) was rolled out to the launch pad at Site 41. After several delays, the R-16 blasted off from Tyuratam on February 2, 1961 at 22:00 local time. Beginning at 165 seconds in flight, the yaw control onboard the second stage failed. The missile and its mockup warhead crashed 530 kilometers north of Siberian city of Tomsk.
Finally a success
The launch on October 28, 1961, concluded the flight tests of the R-16 missile. On October 20, 1961, the surface-based ICBM complex with R-16 missile was formally accepted into armaments. (51)
On November 1, 1961, the first "battle stations" armed with R-16 ICBMs were declared operational in Tyuratam, near the towns of Nizhniy Tagil and Yuriya.
In the meantime in 1961, in Tyuratam, the construction of the silo complex started at Site 60 on the east flank of NIIP-5. Also designated as Object 310, the facility would include three launch silos. A. Nitochkin from Central Design Institute of the Ministry of Defense, also known as TsPI-31, led the construction effort.
The testing of the R-16U version of the missile designed for silo launchers started in January 1962 from ground-based pads.
On June 13, 1962, the R-16U blasted off from the silo facility for the first time. The missile left the silo successfully by a steering engine failed in flight. The problems developed in several consecutive flights but had been solved eventually.
On February 5, 1963, the first unit armed with R-16U was declared operational. On march 30, 1963, three silos with R-16U missiles were put in operational service in Plesetsk. On October 8, 1963, during "Groza" (Thunder) exercise, for the first time, the R-16U was launched from the operational silo in Plesetsk.
On October 19, 1966, the demonstration launch of the R-16U missile was conducted from Pad Number 8 in Tyuratam.
By 1965, 186 launchers for R-16 and R-16Us were deployed across the USSR in Nizhniy Tagil, Bershet, Bologoe, Itatka, Yoshkar-Ola, Novosibirsk, Shadrinsk, and Yuriya.
The R-16 missile was retired in the mid-1970s.
In June 1966, OKB-586 proposed to the government a series of space launchers based on its R-14, R-16 and R-36 missiles. Like two others R-16-derived launchers, it would be equipped with C5M upper stage also developed by OKB-586. The launcher was designated 11K64 and retrospectively named Tsyklon-1. The 11K64 launcher would be able to deliver 700 kilograms of payload to a 1,000-kilometer polar orbit. Unlike his siblings based on R-14 and R-36 missiles, the R-16-derived booster has never flown.
February 2, 1961, at 22:00 local time, (Production Number 3L-5T): Beginning at 165 seconds in flight, the yaw control onboard the second stage failed. The missile and its mockup warhead crashed 530 kilometers north of Siberian city of Tomsk.
March 3, 1961, at 16:59:19 local time, (Number 4L-6T): This time stabilization of the vehicle was lost after separation of the first and second stage and the second stage and the warhead fell 70 kilometers north of city of Birobidzhan.
April 15, 1961, at 16:58:29.5 local time and only three days after Gagarin's flight, the R-16 missile (Number 7L-12T) blasted off from Tyuratam.
