The film adheres to the social mores of the early 1930s. It focuses on traditional courtship and lacks any depiction of non-cisnormative identities or same-sex intimacy.

While the film explores male emotional vulnerability, the narrative remains centered on masculine agency. Women appear primarily as catalysts for emotional arcs within domestic or romantic spheres.

The cast is predominantly white, reflecting the demographic homogeneity of early Hollywood. There is a notable lack of racial or ethnic intersectionality within the primary character arcs.

The story operates within a conventional Western framework emphasizing duty and sacrifice. It portrays the necessity of individual sacrifice for the collective without offering institutional critique.

There are no prominent depictions of physical or neurodivergent disabilities. Characters are defined by the standard physical capabilities required for a submarine setting.
