Leviathan?the world's largest Typhoon-type vessel, a subcarrier equipped with the most advanced twenty-first-century laser technology and the ultimate weapon?a fast, agile fleet of SFV-4B Barracudas, the undersea version of the world's hottest new fighter plane.

The ultimate undersea challenge

Fresh from bloody battle off the coast of Cuba, Leviathan rides out to meet trouble at its source?Alexandria. There the formidable Islamic navy and its allies gather, sailing through the Strait of Gibraltar to block South American oil supplies and bring America to its knees.

Challenged by the Teigei, a Japanese supersub whose superior technology matches Leviathan's, Commander T. Morgan Gray, ace Navy pilot, must lead his intrepid men into a chilling undersea battle?one where only their daring, skill, and courage can snatch victory from the jaws of death and devastating final defeat.
