Harbor of Doom — Irving A. Greenfield

Sleek and swift, America's newest and most sophisticated undersea vessel of war, Manta, under the command of Jack Boxer, is running a deadly race against time. Fanatical Red Army terrorists have stolen three Chinese submarines: a "boomer" with nuclear warheads aimed and triggered to wreak flaming destruction on everything within a 5000-mile radius, and two hunter/killer subs as escort. They plan to hold the world hostage with the threat of nuclear holocaust while they slip undetected into Pearl Harbor, there to re-create the destruction of the U.S. Pacific fleet, this time from beneath the seas. If their plan succeeds, terrorism will dominate the world.

It's up to Boxer and his crew, aided by the most advanced detection and destruction gear ever mounted in an undersea vessel, to stop the plot dead. But time and numbers are against them. Their only hope is to strike and strike hard--to shatter the placid waters of Pearl Harbor with geysers of blood and steel!
