Shuttle 2.01 (Baikal) was the third space shuttle vehicle of the SovietBuran program, serial number 11F35 K3. 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 flight of the Buran and the construction of Ptichka. It was also equipped with Zvezda K-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.
On 22 June 2011 during the day the shuttle was put on a barge to be moved to the MAKS 2011 international air show, which will take place from 16 to 21 August in the Zhukovsky town (Moscow region). In the night of 22–23 June it was seen on the Moskva River.
