Submarine Command (1951) Timeline Explained – Every Event in Order

Ken White ordered the crash dive because a Japanese aerial attack was imminent and he believed waiting would result in the entire submarine being destroyed. The Tiger Shark was under direct aerial threat, and White made the command decision to dive immediately to save the submarine and most of its crew, even though he knew Captain Rice remained topside.

Foreshadowing: Earlier scenes establish White as a decisive commander who must make split-second decisions under pressure.

The film shows that Rice's widow and father do not blame White for the tragedy. They apparently understand that White made a difficult command decision under combat conditions, where waiting would have meant losing the entire submarine and all hands. This lack of blame contrasts sharply with Boyer, who remains the only crew member to hold White accountable.

CPO Boyer blames White because he was present when White refused to wait for Captain Rice to return topside before ordering the crash dive. Boyer pleaded with White to wait, believing there was time. He witnessed White's decision directly and holds the commander personally responsible for the deaths of Rice and the quartermaster, viewing it as a preventable tragedy.

Foreshadowing: Boyer's early plea to wait sets up his persistent resentment throughout the film.

Ken White's guilt is finally exorcised when he makes the decision to surface the submarine despite knowing it exposes him to enemy fire, in order to report the mission's success.

He acts with courage and self-sacrifice, redeeming his earlier choice that prioritized the submarine over his captain.
