Relentless Pursuit aka U-Boat Killers 水下地狱 2 3 1601158 tt8700746 8.0 1 0 German U-515 departs from France in 1944, bound for the African Gold Coast to hunt Allied ships. One thousand miles to the south, the U.S. Navy launches a new hunter-killer task force--a tactical combination of destroyers, escorts, carriers, and aircraft--to prevent German U-Boat resurgence. Witness the showdown between U-boat ace Werner Henke and U.S. Navy Bronze Star recipient Daniel Gallery and see how the unrelenting attack of hunter-killer groups changed how the Battle of the Atlantic was fought and won. 45 https://image.tmdb.org/t/p/w1280/w2TiFmrfzhsnnyZ3RFF3SwhODus.jpg 2018-06-21 2018-06-21 false 0 National Geographic Smithsonian Channel Parallax Film Productions 2025-09-26 16:17:46 WEB_DL NONE 水下地狱.Hell.Below.S02.E03.2018.1080p.WEB-DL.H264.AAC-DJWEB.strm
