Russia has developed a miniaturized nuclear power unit to be installed on cruise missiles which will provide an unlimited flight range and invulnerability to missile and air defence systems. Russian President Vladimir Putin said the launch of the missile and the tests on the ground allow for starting work to create a fundamentally new type of weapon; a strategic nuclear missile equipped with a nuclear power plant. 

TASS reported the trials of the miniaturized nuclear power plant, which are also planned to be used on underwater drones, have been completed.
