Ptichka

2K (GRAU index serial number 11F35 2K, NPO Molniya airframe number 1.02), often referred to as Ptichka (Russian: Птичка, "little bird", although this was also a nickname for all orbiters in the programme), is the second Buran-class orbiter, produced as part of the Soviet/Russian Buran programme. Although 2K was the 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 2K was Burya (Russian: Буря, "storm" or "tempest").
