2.03 (Buran-class spacecraft)

2.03 (GRAU index serial number 11F35 5K) is the designation of the fifth Soviet/Russian Buran-class orbiter to be produced as part of the Buran programme. It was never officially named.

2.03 was a second series shuttle orbiter, as shown by the '2' in its number. Construction of 2.03 was barely underway when the entire Buran programme was halted in 1993, and as what parts of it had been built were dismantled shortly afterwards. Nothing remained of it by 1995.
