Battle Stations

Description for BATTLE STATIONS by Irving A Greenfield:

When U.S. Intelligence discovers that Russia's most lethal submarine lies crippled at the bottom of the ocean, they instantly dispatch our own high-tech killer sub, the Shark, to blast the enemy vessel into oblivion.  The mission appears to be simple---until the Shark reaches the coordinates and finds itself surrounded by an armada of Soviet warships!  Now it's one U.S. submarine against the massed might of the Russian Navy.  The hunter has become the hunted---and the ocean shudders from the monumental battle as sailors find either death or glory in a blood red sea!
