Operation White Out

Mac McDowell recovers from injuries he received in Operation Arctic Sting and is assigned as Executive Offier on USS Teuthis. Teuthis is tasked with laying SOSUS arrays in the southern Atlantic and off Thurston Island, Western Antarctica. Teuthis tangles with Argentine subs in the Atlantic and receives help from the Orca Borysko. Teuthis lays the SOSUS array off Thurston Island with Borysko's help, and Mac with his team place a transmitter on a nearby mountain peak, aided by a helicopter from Palmer Station. The chopper is shot down by a missile fired from a Chinese Han-class sub. Teuthis discovers a Tiwanese underwater oil operation off Thurston Island interacts with a Taiwanese AIP sub. Teuthis is tasked with escorting the sub and an underwater tanker to Taiwan under the cover of the largest military marine exercise since World War II--PacEx89. During the transit, Teuthis is attacked by a Chinese Han-class sub and a previously unknown North Korean AIP sub despite the protection provided by three U.S. fast attack subs.

Will Mac and Teuthis complete their mission, or will they finally meet their watery graves on the Pacific Ocean aryssal plain?
