Cinematographer Tony Gaudio was nominated for the 1943 Academy Award for Best Cinematography (B&W). (Arthur Miller won for Song Of Bernadette.)
Film critic Bosley Crowther reviewed the film for New York Times, stating, "Randolph Scott gives a beautiful performance ..." but most of the review focused on the drama of the RCN corvettes at sea, "In a virtually documentary treatment of life aboard the K-225, Producer Howard Hawks and Richard Rosson, director of the film, have realized the physical strain and torment of work in a rampant corvette. They have pictured with indubitable fidelity the discomforts of an escort vessel's crew-the eternal tossing and rolling of the ship in a moderate sea; her plunging and gyrating in the grip of a North Atlantic gale, with tons of sea water pouring over her, battering and soaking every man."
Robert Mitchum, credited as Bob Mitchum, has a minor supporting role, one of 20 Hollywood films he made in 1943.
