Greyhound
When the Captain refers to "Huff-Duff," he is referring to high-frequency direction-finding. This was a key method of how Allied naval forces detected and tracked German U-Boats: the Kriegsmarine's U-boat fleet maintained a high amount of radio traffic with its shore command and with each other for their Wolfpack tactics against Allied shipping. Huff-Duff allowed Allied naval ships to detect those radio transmissions and determine the location of those transmitting ships to attack them.,One of the German U-boat commanders taunts Greyhound over the radio. This would never have happened in reality. Each Navy ship had a radio signal direction finder and if a U-Boat broke radio silence, triangulation would reveal its exact position.,Gray Wolf: [on radio] Greyhound, good luck surviving the night.,During the first part of the end credits, some black and white WW2 era clips are shown.,Featured in Half in the Bag: Blumhouse's Dirty Secret (2020),It Came Upon A Midnight Clear

Courtesy of Black Toast Music,Spectacle? Dramatization? No. This movie allowed me to experience ww2 naval combat without the bombast of the usual action movie. It felt realistic with a decent amount of suspense, a glimpse through the eyes of the captain.,
