Ptichka (, "little bird"; GRAU index serial number 11F35 2K, Article 1.02 or OK-1.02) GRAU was a nickname for the second Buran-class orbiter, produced as part of the Soviet/Russian Buran programme. Although OK-1.02 was closest to being completed of any of the Buran-class orbiters (after the orbiter Buran), it was never finished. The program was officially cancelled in 1993, at which point the shuttle was 95-97% complete. The proposed official name for OK-1.02 was Burya (, "storm" or "tempest"). Projected flights Ptichka was preparing for its maiden flight to perform the first fully regular Buran-class orbiter operation. (The flight of Buran 11F35 1K Article 1.01 was lacking regular thermal control and power systems.) This orbiter was also planned to receive a remote manipulator and docking system. As of 1989 the orbital flight test program for the second orbiter was split into two missions, with a space station approach test on the second, but delays in preparations changed the plans to perform all test tasks in one maiden flight, scheduled for December 1991. The mission profile included: unmanned launch automatic docking with Mir's Kristall module. crew transfer from Mir to the spaceplane, with onboard systems testing in course of twenty-four hours. remote manipulator testing undocking and autonomous flight in orbit Manned Soyuz TM No.101 docking to the orbiter. crew transfer from the Soyuz to the spaceplane and on board work in the course of twenty-four hours automatic undocking and landing After program cancellation In August 1995, OK-1.02 was moved into storage within the MZK building (Russian: МЗК, Монтажно-Заправочный Комплекс, Assembling and Fueling Facility) at Baikonur Cosmodrome, alongside the full size test article OK-MT. Ownership The ownership of OK-1.02 and its sister ship Buran has been contested since the fall of the Soviet Union, with the director of Roscosmos Dmitry Rogozin attesting that he had tried to purchase Buran and return it to Russia, but became entangled in legal disputes on its true owner. The contractor for the Buran space programme, RSC Energia, had set up a subsidiary CJSC Energia to manage its overseas assets in 2004, which were then transferred to RSE Infrakos in 2004 and relinquished to JSC KRISP Aelita, a joint Russian-Kazakh company. Kazakh businessman Dauren Musa asserted ownership of OK-1.02 in 2011 after purchasing the company's shares, which was disputed by the Kazakh government, but reaffirmed by the country's court after litigation proceedings.
