Russia has hidden two of its most valuable warplanes in a remote airbase just days after a stunning Ukrainian drone strike wreaked havoc on its elite bomber fleet.

Satellite images have revealed that the pair of supersonic Tu-160 strategic bombers - each carrying a $500million price tag - have been relocated more than 4,000 miles from the warfront to Anadyr, an isolated Cold War-era airfield nestled on the desolate Chukotka Peninsula.

The dramatic retreat comes after Ukraine's spy agency, the SBU, pulled off what has been dubbed Operation Spider's Web on June 1.

It was a meticulously choreographed drone blitz that reportedly damaged several of Moscow’s rare strategic bombers - aircraft capable of carrying nuclear weapons and critical to Russia’s long-range strike capability.

In a slickly produced video released by the SBU, the daring mission was laid bare.
