BOR-4

Enumeration of all the flights

N°	Designation	Launch date	Detail
1	-	05.12.1980	First try of "BOR-4" for the orbital flight
2	Cosmos-1374	03.06.1982	Sea landing in the Indian Ocean at 560 km in the south of Cocoa's islands. The Australian reconnaissance planes took detailed photos of the lifting body and its recovery.
3	Cosmos-1145	15-16.03.1983	Sea landing in the Indian Ocean at 560 km in the South of Cocoa's islands, once again watched out by the Australian reconnaissance plane.
4	Cosmos-1517	27.12.1983	To avoid the espionage from the Westerners the lading zone is moved in Black Sea. The braking impulse is given above the North Atlantic Ocean.
5	-	04.07.1984	According to foreign sources the flight took place at 130 km of height with a suborbitale trajectory. The USSR did not confirm this flight.
6	Cosmos-1614	19.12.1984	Sea landing in the Black Sea after accomplishing a turn. The lifting body is lost in sea by the recovery services.
7	-	20.10.1987	According to foreign sources the flight took place at 130 km of height with a suborbitale trajectory. The USSR did not confirm this flight.
