Russian nuclear submarine makes 30-day trip under Arctic ice

A Russian Delta-III class ballistic missile submarine has successfully sailed from a naval base in northern Russia to the Pacific Ocean under the Arctic ice floe, a Navy spokesman said on Tuesday.

"The Ryazan strategic nuclear submarine arrived at a naval base on the Kamchatka Peninsula after a more than 30-day underwater trip," Capt. 1st rank Igor Dygalo said.

Ryazan is a Project 667BDR Delta III class strategic nuclear submarine, which entered service with Russia's Northern Fleet in 1982. It has a crew of 130 and can travel underwater without coming to the surface for up to 90 days.
