Russian firm unveils stealth Submarine/Patrol vessel hybrid

Russia’s Rubin Design Bureau has unveiled a larger version of its Sentinel submersible patrol ship, first introduced in April.

The 72-meter (236-foot), 1,300-ton vessel features the “largest weapons suite,” including “a small-caliber automatic gun, two missile launchers, and four 324mm torpedo tubes,” TASS quoted the state-backed submarine design center as stating.

The vessel’s larger frame allowed a modification in its design, making it more stable and stealthy.
