Ptichka (Russian: Пти́чка, IPA: [ˈptʲitɕkə], Little Bird) is an informal nickname for the second space shuttle orbiter to be produced as part of the Soviet/Russian Buran program. It carried the GRAU index serial number 11F35 K2 and is - depending on the source - also known as "OK-1K2", "Orbiter K2", "OK 1.02" or "Shuttle 1.02". This Buran-class shuttle orbiter was never officially named. Ptichka was an informal nickname for all of the Buran-class orbiters.
OK-1K2 is distinguishable from the other Buran-class orbiters by a red framework attached to the top of its cargo bay doors.
Construction of the second orbiter started in 1988, and although OK-1K2 was closest to being completed of any of the Buran-class orbiters (after the OK-1K1 orbiter), it was never finished. The program was officially canceled in 1993, at which point the shuttle was 95-97% complete.
Projected flights as of 1989:
- 1991 — unmanned first flight, with a duration of 1–2 days.
- 1992 — unmanned second flight, with a duration of 7–8 days. Orbital maneuvers and space station approach test.
Changed in 1991:
- December 1991 — unmanned second flight, with a duration of 7–8 days. Orbital maneuvers and space station approach test:
- automatic docking with Mir's Kristall module.
- crew transfer from Mir to the shuttle, with testing of some of its systems in the course of twenty-four hours, including the remote manipulator
- undocking and autonomous flight in orbit
- docking of the manned Soyuz-TM 101 with the shuttle
- crew transfer from the Soyuz to the shuttle and on board work in the course of twenty-four hours
- automatic undocking and landing
