L1 Complex 1961
The earliest Sever project tackled such problems as manoeuvring in orbit, rendezvous and docking, use of manipulators to move station modules, and testing of lifting re-entry vehicles. Sever (left) was 50% larger than Soyuz, which replaced it by late 1961 in OKB-1 studies. The Vostok-Zh manoeuvrable Vostok spacecraft (right) would be used as a manned tug to assemble the stages in low earth orbit.
Russian manned spacecraft. Study 1959. Sever was the original OKB-1 design for a manned spacecraft to replace the Vostok. It was designed to tackle such problems as maneuvering in orbit, rendezvous and docking, and testing of lifting re-entry vehicles.

The Sever had the same 'headlight' shape as the later Soyuz re-entry vehicle, but was 50% larger. But application of the principal of moving all possible systems to a jettisonable living module resulted in the smaller Soyuz capsule design for the same number of crew.

  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Soyuz Russian orbital launch vehicle. The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...

Sever Chronology


1959 March 1 - .
  • OKB-1 preliminary work on circumlunar spacecraft - . Nation: USSR. Related Persons: Feoktistov. Program: Lunar L1. Class: Manned. Type: Manned space station. Spacecraft: Sever. The first design sketched out was known as Sever (North). The reentry capsule had the same configuration as the ultimate Soyuz design but was 50% larger. By summer 1959 Feoktistov had reduced the size to that of the later Soyuz, while retaining the three-man crew size.

1961 During the Year - .
  • Competing designs for a reliable manned spacecraft to succeed Vostok. - . Nation: USSR. Spacecraft: Vostok-Zh; Soyuz A; Soyuz B; Soyuz V; Sever. The Soyuz or Sever designs would utilize body lift to reduce G forces and allo the crew to make re-entries at hyperbolic speeds - when returning from the moon, or Mars. An associated design was a manned orbital tug version of the Vostok capsule to assemble spacecraft in low earth orbit.

1961 March 11 - .
  • New manned spacecraft - . Nation: USSR. Related Persons: Vershinin. Spacecraft: Vostok-Zh; Raketoplan; Sever. The VVS TTZ requirements document for the next generation Soviet manned spacecraft is approved by Vershinin. It is to accommodate two cosmonauts, have a launch mass of 6.5 to 7.0 tonnes, be capable of manoeuvring and changing its orbit at altitudes of 270 to 300 km altitude. The TDU engine is to be restartable, and the spacecraft will have a system to reliably change and hold its orientation in flight. The crew will be returned in a pressurised spherical re-entry capsule, but still be provided with ejection seats for separate landing of the crew in emergencies. The craft will be capable of flights of 15 to 20 days duration and be equipped with redundant communications systems. Kamanin points out the necessity of coordinating the TTZ with OKB-1. Vershinin and Ponomarev fight over whether to consider Chelomei's Raketoplan as meeting the requirement. Kamanin's position is that Korolev's Vostok is now flying reliably, while the Raketoplan is a 'crane in the clouds' - it might come to them some day, but who knows when.

1961 April 10 - .
  • Vostok preparations - . Nation: USSR. Related Persons: Rudnev; Moskalenko; Korolev; Gagarin; Titov; Nelyubov; Popovich; Nikolayev; Bykovsky. Program: Vostok. Flight: Vostok 1. Spacecraft: Sever. Kamanin plays badminton with Gagarin, Titov, and Nelyubov, winning 16 to 5. At 12:00 a meeting is held with the cosmonauts at the Syr Darya River. Rudnev, Moskalenko, and Korolev informally discuss plans with Gagarin, Titov, Nelyubov, Popovich, Nikolayev, and Bykovsky. Korolev addresses the group, saying that it is only four years since the Soviet Union put the first satellite into orbit, and here they are about to put a man into space. The six cosmonauts here are all ready and qualified for the first flight. Although Gagarin has been selected for this flight, the others will follow soon - in this year production of ten Vostok spacecraft will be completed, and in future years it will be replaced by the two or three-place Sever spacecraft. The place of these cosmonauts here does not indicate the completion of our work, says Korolev, but rather the beginning of a long line of Soviet spacecraft. Korolev predicts that the flight will be completed safely, and he wishes Yuri Alekseyevich success. Kamanin and Moskalenko follow with their speeches. In the evening the final State Commission meeting is held. Launch is set for 12 April and the selection of Gagarin for the flight is ratified. The proceedings are recorded for posterity on film and tape.

1961 May 20 - .
  • Vostok 2 discussions - . Nation: USSR. Related Persons: Yazdovskiy; Bushuyev; Feoktistov; Korolev. Program: Vostok. Flight: Vostok 2. Spacecraft: Sever; Vostok. Kamanin, Yazdovskiy, Bushuyev, and Feoktistov fly to Sochi. Korolev arrives on the next flight, and discussions begin on plans for the second Soviet manned spaceflight. Korolev wants a one-day/16-orbit flight, but Kamanin thinks this is too daring and wants a 3 to 4 orbit flight. Korolev rejects this, saying recovery on orbits 2 to 7 is not possible since the solar orientation sensor would not function (retrofire would have to take place in the earth's shadow). But Kamanin believes one day is too big a leap since the effects of sustained zero-G are not known. He finally agrees to a one-day flight, but with the proviso that a manually-oriented retrofire can be an option on orbits 2 to 7 if the cosmonaut is feeling unwell. Korolev reports that the new Sever spacecraft should be ready for flight by the third quarter of 1962. OKB-1 is working hard on the finding solutions to the problems of manoeuvring, rendezvous, and docking in orbit. Kamanin tells Korolev that it would be difficult to recruit and train three-man crews in time to support such an aggressive schedule.

1962 February 10 - .
  • Sever spacecraft trials - . Nation: USSR. Related Persons: Voronin. Spacecraft: Sever. Summary: Two officers start a 15 day test aboard a mock-up of the Sever spacecraft, but without the participation of the IAKM. The whole thing was planned by Voronin's OKB in GKNII..

1962 February 13 - .
  • Sever trial - . Nation: USSR. Related Persons: Voronin; Yazdovskiy; Vershinin; Bushuyev. Spacecraft: Sever. Summary: Vershinin, Bushuev and others are at OKB-124 for Voronin's Sever experiment. It was a bit mistake not to include IAKM in the 15-day experiment. This is Yazdovskiy's doing. He wanted to get a second source due to problems with IAKM's equipment.
