Shuttle 2.01 (Baikal) was the third space shuttle vehicle of the SovietBuran program. Its serial number is GRAU index 11F35 K3. Shuttle 2.01's construction was not complete when the Buran program was ended (30-50 percent done), so it remains unfinished.
The 2.01 is the first of a second series of Burans. The main differences between the second series and the first are located in the cockpit, which has been improved using feedback from the earlier models of Buran-class shuttles, such as the flight of OK-1K1 and the construction of OK-1K2. It was also equipped with ZvezdaK-36RB ejection seats for the first manned flights.
After residing at the Tushino factory where it was constructed, it was incorrectly announced in 2006 that Shuttle 2.01 would be put on display in the Sinsheim Auto & Technik Museum, Germany. However, the German Museum had actually bought OK-GLI, the jet-powered Buran atmospheric test vehicle, which will be on display in its own new hangar from September 2008.
