The Russian Navy's second Borei-class nuclear-powered ballistic missile submarine (SSBN), Alexander Nevsky, has successfully completed sea trials, the Sevmash shipyard said.

Sevmash shipyard was cited by RIA Novosti as saying that the SSBN Alexander Nevsky has completed sea trials, while the work is on schedule for the Borei-class project.

The shipyard did not disclose the details of when the submarine would join the Russian Navy.

In early September, the Russian Ministry of Defence (MoD) deferred the trials of second and third Borei-class submarines, Alexander Nevsky and Vladimir Monomakh respectively, following an unsuccessful launch of a Bulava submarine-launched ballistic missile (SLBM).

By 2015, the Russian Navy is expected to receive eight Borei-class submarines to replace the existing Project 941 and Project 667 (Nato Typhoon and Delta-3 and Delta-4) class ballistic missile, as part of a state 2020 rearmament procurement programme.

The 170m-long Alexander Nevsky has a hull diameter of 13m, a crew capacity of 107, a submerged speed of 29k and a maximum depth of 450m.

Powered by an OK-650 nuclear reactor and AEU steam turbine, Alexander Nevsky can carry up to 16 ballistic missiles and torpedoes, including the Bulava (SS-NX-30) sea-based SLBM.

"Alexander Nevsky can carry up to 16 ballistic missiles and torpedoes."

Designed by the Moscow Institute of Thermal Technology, the Bulava replaces the R-39 solid-fuel SLBM.

The Russian Navy's first Yasen / Graney-class nuclear-powered attack submarine, SSGN Severodvinsk (K-329) is expected to begin final trials in the White Sea next month, the shipyard said.

The 111m-long and 12m-wide Yasen-class submarine has a full load displacement of around 13,000t, can cruise at a top speed of 35k and accommodate a crew of 50.

Russia is planning to spend $166bn on its military rearmament programme through 2020, which will see the navy equipped with ten Graney-class nuclear attack submarines and 20 diesel-electric submarines, including six Varshavyanka-class vessels.
