Origin: ICBM of first generation (R7 Semiorka)

In Feb 1953 the Soviet government decided to built a intercontinental rocket. The project management was affected to S.P. Korolev's OKB while V.P. Gouchko's one was in charge of the motors.
Originaly the program planned to send a 3 ton payload at 8000 km. It transformed in late 1953 when the thermonuclear warheadwas found to weigh 6 tons. The modified project was accepted in August 1954 under the name R7 (or Semiorka).

The R7 was a rocket made of a central body with 4 lateral boosters as the first stage. The conical boosters, were 19.8 m high and 2.68 m diameter (base). The main body, known as Block A, was 28.75 m high and a maximum diameter of 2.95 m at the upper fixation point of the boosters. The missile was known in the US as SS-6 Sapwood; it weighed 267 tons at takeoff and was 30.5 m high.

The first tests of the motors (static bench) took place in Sep 1956. The motors had 4 chambers consuming the couple oxygen-kerosen. The RD-107 was active during 320 seconds and provided 976 kN thrust in vacuum (Isp = 305 s). It featured two verniers. The RD-108 active 120 seconds developped 912 kN in vacuum (Isp = 308 s) and featured 4 verniers.

Missiles tests started on 15 May 1957 from Tyuratam (near Baïkonour), specially created for the R7. After 3 failures the first successful flight took place on 21 August the same year. A second success on 7 September set on the green light to try and achieve a satellisation.

Usage of Semiorka without top stage

The first artifical satellite Sputnik 1 was launched on 4 Oct. 1957 from Tyuratam. Only the top stage of the R7 rocket was modified to create the rocket named 8K71 in USSR and A / SL1 in the US.

This launcher was further used for 2 satellites. On 3 Nov 1957 it put the 508 kg Sputnik 2 into orbit and its Laïka passenger. On 15 May 1958 after a failure in April Sputnik 3 (1327 kg) was also put onto orbit.

The Semiorka configuration was such that it was a military device difficult to use. On the contrary it was a great base for a space launcher and therefore it is still used 40 years after its first launch. The constructor of this rocket is now KB Photon, a division of TsSKB Samara.

The RD-107 and RD-108 motors, now built by NPO Energomash, have been enhanced. Their performance is now 1000 kN in vacuum (Isp = 314 s) for the former and 941 kN (Isp = 315 s) for the latter.

Usage of Semiorka with a Block E third stage

The project of Lunar probe launches required a third stage for the R7. This Block E top stage was ordered from the S.A. Kosberg KB (now KB Khimautomatiki) in Feb 1958. It was to be the first liquid stage fired up in vacuum. Its RO-7 motor (or RD-0105) using liquid onxygen and kerosen developped 49 kN thrust (Isp 316 s). It was 2.58 m diameter, 2.98 m long and weighed 8.1 tons, including 7 tons propellant.

After several failures since August 1958 the first sucessful launch of the 3-stage R7 occured to send Luna 1 to the moon on 2 Jan 1959. The probe flowby 6400 km from the objective before acquiring a solar orbit. A second failure in August occured before the first moon impact with Luna 2, launched on 12 Sep 1959. Then Luna 3 launched on 4 October took the first pictures of moon's hidden side. Two failures ended the 8K72 carrier, also known as A1 / SL2.

The Block E will be enhanced in 1960 for a piloted launch. A new RD(448 (or RD-0109) developped 54.5 kN thrust (Isp = 324 s).

The first Korabl spacecraft ( Sputnik 4) was launched on 15 May 1960. It was the first of 7 tentatives including 5 successful launches which preceded the 6 Vostok flights. The Vostok rocket alias 8A92 or A1 / SL3 in the West will also be used to launch automatic satellites. In this configuration it is 38.4 m high and weighs 287 tons. It was 38.4 m high, 287 tons, and could orbit 4.7 tons in LEO or 1.1 tons in 900 km sunsynchronous orbit. This rocket launched:
- reconnaissance satellites of first generation (Cosmos Zenith) until 1967
- meteorological (Cosmos, Meteor) and observation (Cosmos, IRS) satellites until 1991

Note: it seems that the Poliot satellites (1963-1964) built by OKB Chelomei were launched by a modified Vostok named SL5. The SL10 launched used to launch Cosmos 101 and Cosmos 125 (1965-1966) would also have been launched by a modified R7.

Usage of Semiorka with a Block I third stage

The 4-stage version of Semiorka was designed in 1959-1960 for interplanetary missions. The Block I third stage was built by KB S.A. Kosberg. It was 2.66 m diameter and 8.1 m long. It weighed 24 tons including 21 tons propellant. It's 4-chamber motor block RO-9 (or RD-0107) used liquid oxygen and Kerosen. It provided 298 kN (Isp = 324 s). The fourth stage, Block L, was built by OKB S.P. Korovev. It was aimed by a CI-5400 integrated flux motor developping 67 kN (Isp = 340 s) with the same propellant.

The two first tentatives to Mars failed in October 1960. In Februry 1961 the first probe to Venus stayed in transfert orbit because of a Block L failure. The second launched on 12 Feb was correctly placed on solar orbit and became Venus 1. in 1962 the 3 launches towards Venus failed and only 1 launch to Mars in Oct.-Nov. succeeded on 1 Nov.

After such a difficult start the 8K78 (A2e / SL6) became more reliable and launched several types of space probes (Luna, Zond, Venus and Mars).

A version without fourth stage designed to launch manned vehicles was named 11A57 (or A2 / SL4). It was first tested in Nov 1963 with Cosmos 22, and then was used for the Voskhod program and to launch second generation Zenith reconnaissance satellites.

In Feb 1964 the 4-stage launcher was improved by replacing the 3rd stage motor by a RD-461 (or RD-0110) giving birth to the 8K78M rocket better known an Molniya. This launcher is 42 m high and weighs 306 tons. It can orbit 1.6 tons on an elliptic 12 hours path used by the Molniya telecommunication satellites. This launcher is also used for:
- space probes to the moon (1.6 tons), Venus (1.2 tons) or Mars (0.95 tons)
- scientific satellites Prognoz (0.9 tons) on very eccentric orbits
- early warning satellites Oko (Cosmos series) on 12 hour Molniya-type orbits

The 3-stage version Soyuz alias 11A511 appeared in Nov 1966 for the launch of Cosmos 133, then the version Soyuz M (11A511M) in Dec 1971 for Cosmos 470. The last version Soyuz U (11A511U) was launched for the first time in Mai 1973 with Cosmos 559.

For the manned flight a Soyuz U2 version exist; it is more powerful. It's central motor (RD-118) uses cycline instead of kerosen as propellant. The thrust of each booster is 1030 kN (ground level) and 1250 kN in vacuum (Soyuz U: 1015 kN and 1240 kN respectively). The thrust of the central motor is 1010 kN (980 kN for Soyuz U). But the manned launches will from now on be made with kerosen, because the cycline plant in Oufa (Bachkirie) was closed of budget problems. NPO Energomach which produces the motors plan to compensate the performance with new injectors which enhance the combustion fo propellant.

Soyuz is in fact the most launched vehicle in the world (over 700 times). It measures 45 to 50 m depending on the versions, weighs 310 tons and can orbit ~7 tons in LEO. In addition to the Soyuz spacecrafts which gave them its name, the rocket was used for:
- several types of reconnaissance satellites (Zenith, Kometa, Yantar, etc.)
- their civilian counterparts ( Bion, Resurs F, Foton, etc.)
- the Progress supply ships

A2 / SL4 (Soyuz) launches

Commercial version: Soyouz-Ikar

The maximum capacity of the Soyuz U is only attained for launches of retrievable probes in LEO (200 km 51.8°) when the cap is jettisoned early. This performance falls to 6.2 tons at 200 km when the cap is released later, as for the more fragile commercial payloads; and 5 tons at 300 km. The Molniya M can place 1.75 tons on a 500/40000 km orbit, 62.8° inclination, or 1.5 tons in sunsynchronous orbit at 800 km altitude.

The Russian-French firm Starsem set up by Aerospatiale (35%), Arianespace (15%), RKA (25%) and Samara center (25%) was created in August 1996 to sell Semiorka vehicles (Soyuz, Molniya and derivatives).

The new version is tailored for satellite constellation launches. It has an Ika stage under the cap like Molniya's Block L. This stage equipped with re-ignitable motors has already flown over 30 times with maneuverable observation satellites. The Soyuz-Ikar will be able to deliver 2.5 tons payload in 1400 km 51.8° orbits or 2.35 tons in polar orbit at the same altitude. The first use of the vehicle should be for 4 Globalstar satellites.

Soyuz 2 (Rus)

A enhanced Semiorka named Rus should be available in 1999. It will be used to launch the Cosmos, Foton, Bion and Resurs F satellites with a 3-stage version and Molniya, Meteor, Tselina and Resurs O satellites with a 4-stage version.

This new launcher, 51.2 m high, will have the same 3 stages of Soyuz with an improved propulsion and guidance systems. The RD-0101 motor of the 3rd stage will be replaced by a RD-0124 with integrated flux of same thrust, but with a 359 s Isp and a burn duration extended at 300 s. Moreover deployable nozzle will suppress the need for the 4 vernier motors. The top stage (in 4-stage version) will be the Fregat of NPO Lavotchkine. It weighs 6.5 tons including 5.3 tons of stockable propellant (NTO-UDMH). It will be equipped with a S5-92 motor from KB KhimMach of 20 kN which can be re-ignited up to 20 times. This rocket will have 900 kg more performance than the current Soyuz.
