It performed the longest burn of the three unmanned LK Lander tests. It finished in a 186 km by 11,804 km orbit. This test qualified the lander as flightworthy. The LK was the only hardware system of the Soviet lunar landing project reaching this status. In 1980-81 there were fears that it might carry nuclear fuel. When in reentered over Australia on August 22, 1981 the Soviet Foreign Ministry in Australia admitted that Kosmos 434 was an “experiment unit of a lunar cabin,” or lunar lander.
