Satellite photos show destroyed bombers at a Russian air base that Ukraine said it hit

Satellite photos analyzed by The Associated Press on Wednesday showed seven destroyed bombers on the tarmac at a Russian air base in eastern Siberia, one of the targets Ukraine said it struck with drones in one of the most daring covert operations of the 3-year war.

The photos provided by Planet Labs PBC showed aircraft wreckage and scorched areas at the Belaya Air Base, a major installation for Russia's long-range bomber force. In the images, at least three Tu-95 bombers and four Tu-22Ms appeared to be destroyed.

The planes were parked on an apron beside a runway surrounded by grassland. Other aircraft at the base appeared unscathed.

Ukraine claimed that 41 Russian warplanes, including strategic bombers and other types of combat aircraft, were destroyed or damaged in Sunday's operation, which officials said was planned over 18 months. The attack delivered a heavy blow to Russia's air force and its military prestige.

The Russian Defense Ministry said the attack set several warplanes ablaze at air bases in the Irkutsk region and the Murmansk region in the north, but the fires were extinguished. It also said Ukraine also tried to strike two air bases in western Russia, as well as another one in the Amur region of Russia's Far East, but those attacks were repelled.

Russian President Vladimir Putin hasn't commented on the issue.

The Tu-95 is a is a four-engine turboprop plane that can fly intercontinental missions and was designed in the 1950s to rival the U.S. B-52 bomber.

The Tupolev Tu-22M is a sweep-wing twin-engine supersonic bomber.

Russia has used the heavy planes in the war to launch waves of cruise missile strikes across Ukraine.

For decades, long-range bombers have been part of the Soviet and Russian nuclear triad that also includes land-based intercontinental ballistic missiles and atomic-powered submarines carrying ICBMs. The strategic bombers have flown regular patrols around the globe showcasing Moscow's nuclear might.
