"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.
The submarine is armed with 16 R-29RM (SS-N-23 Skiff) ballistic missiles with a range of 8,000 km (about 5,000 miles).
Commenting on the submarine's successful mission, Russian Navy Commander, Adm. Vladimir Vysotsky said it had reaffirmed the Russian submarine fleet's ability to conduct strategic missions in the Arctic.
"The Navy continues to play an important role in safeguarding Russia's maritime economic and research activity throughout the world, including in the Arctic," the admiral said.
