Russian manned combat spacecraft. Study 1964. The Soyuz 7K-PPK (pilotiruemiy korabl-perekhvatchik, manned interceptor spacecraft) was a revised version of the Soyuz P manned satellite inspection spacecraft.

The PPK provided the cosmonaut with a standoff capability for destruction of enemy satellites. For this purpose the Soyuz was equipped with eight small rockets.

As in the Soyuz P, the spacecraft would rendezvous with the enemy satellite. But the cosmonaut would remain in the spacecraft, using visual and other on-board systems to inspect the satellite. If the satellite was to be eliminated, the Soyuz would back off to a distance of 1 kilometer, and then destroy it using the on-board rocket-mines. Delays in the development of the Soyuz led to abandonment of this plan.


Crew Size: 2. Habitable Volume: 13.00 m3.

AKA: 11F71.
Gross mass: 6,700 kg (14,700 lb).
Height: 6.50 m (21.30 ft).

  • 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...

Soyuz PPK Chronology

1964 Duing the year - . LV Family: R-7. Launch Vehicle: Soyuz.
  • Development of Soyuz-R and Soyuz-P begun. - . Nation: USSR. Related Persons: Kozlov. Program: Almaz. Class: Manned. Type: Manned spacecraft. Spacecraft: Soyuz R; Soyuz P; Soyuz PPK; Soyuz 7K-TK. KB Kozlov began active development of the military applied versions of the Soyuz. A new version of the R-7 launch vehicle, the 11A514, was put into development to support launch of the Soyuz-P, now designated the 7K-PPK (pilotiruemovo korablya-perekhvatchika, manned interceptor spacecraft). The Soyuz-R would include the small orbital station 11F71 with photo-reconnaissance and ELINT equipment. To dock with the 11F71 station Kuibishev developed the transport spacecraft 11F72 7K-TK. This version of the Soyuz was equipped with rendezvous, docking, and transition equipment, including an airlock, that allowed the two cosmonauts to enter the station without using EVA. The launch vehicle for the 7K-TK would be the 11A511, known today as the Soyuz.

  • Military Soviet of the VVS Staff - . Nation: USSR. Program: Lunar L1. Flight: Soyuz A-1; Soyuz A-2; Soyuz A-3; Soyuz A-4. Spacecraft: Soyuz A; Soyuz R; Soyuz P; Soyuz PPK. No significant decisions are made. Discussion of the 3 December 1963 resolution to start development of the 7K Soyuz spacecraft. Although the resolution foresees completion of the first spacecraft during 1964, and first flights in 1965-1966, there is not one word on training of cosmonauts for such missions. Scientific versions, for manned flight to the moon and planets, as well as military variants, are foreseen.

  • American space plans - . Nation: USSR. Related Persons: Bykovsky; Gagarin. Spacecraft: Soyuz R; Soyuz PPK; MOL; Almaz APOS. Following an overview of the planned trip of Bykovsky and Gagarin to Sweden and Norway on 1-15 March, American military space plans are reviewed. There are many fantastic projects, over a wide and well-financed front. Currently reconnaissance satellites are flying, to be followed by inspection, and then anti-satellite satellites in 3 to 5 years. After that manned military space stations are planned, manoeuvrable manned spacecraft, and the establishment of scientific and military bases on the moon. Despite this big US program, the Soviet military leadership shows no interest in Russian exploitation of space for military purposes.

1964 February 27 - .
  • Military space plans - . Nation: USSR. Related Persons: Malinovskiy. Spacecraft: Soyuz R; Soyuz PPK. A meeting of the VVS General Staff with Marshal Malinovskiy reviews military roles in space. The VVS are tasked with developing environmental control systems for manned spacecraft, abort and recovery systems, training cosmonauts, and recovery of returned space capsules. The RVSN are responsible for final check-out and launch of spacecraft; the PVO are responsible for tracking and control of manned spaceflights. Kamanin pushes for VVS to take a role in development of manned military spacecraft as an extension of its responsibility for combat aircraft. Some of the generals agree in principle, but have no understanding of the new technology and how it might be appropriately applied. Others are opposed. Meanwhile the cosmonauts are taking their examinations in avionics technology, and Kamanin continues to argue for reorganisation of the TsPK cosmonaut training centre to include new specialities and training facilities (e.g. to support specialist engineer, navigator, and scientist cosmonauts).

1965 February 2 - .
  • Cosmonaut organisation - . Nation: USSR. Related Persons: Nikolayev; Beregovoi; Malinovskiy. Program: Lunar L1; Lunar L3. Spacecraft: Soyuz A; Soyuz B; Soyuz V; LK-1; Soyuz PPK; Soyuz R. Kamanin will organise the cosmonauts into two groups: the first group will be commanded by Nikolayev, and the latest group by Beregovoi. They will be assigned to support and train seven missions: military space (reconnaissance, interceptor, and combat spacecraft); space navigation; life support and rescue systems; communications and telemetry systems; scientific orbital stations; lunar fly-by; and lunar landing expeditions. All of this may be for nought, since Marshall Malinovskiy has said that heavy launch vehicles and lunar flights have no military utility and should be funded and handled by the Academy of Science.
