The BOR-5 (Russian: БОР-5, «Беспилотный Орбитальный Ракетоплан 5», romanized: Bespilotnyi Orbital'nyi Raketoplan 5, lit. 'Unpiloted Orbital Rocketplane 5') is a 1:8 sized test flight vehicle, used to study the main aerodynamic, thermal, acoustic and stability characteristics of the Buran. It follows upon the BOR-4 reentry test vehicle.
It was put into a suborbital trajectory by a K65M-RB5 rocket launched from Kapustin Yar, near Volga, towards Lake Balkhash at the altitude of about 100 km with velocities from 4000 to 7300 kilometers per second.
