World War II submarine crews were often too small to require a resident doctor. Limited space and covert operations also reduced the expectation that a submarine would divert to answer an emergency. Submarine tenders supplied permanent medical support for the flotilla, while crews at sea relied on manuals and basic treatment skills when isolated. Larger surface ships needed doctors for their own crews and for emergencies they could be called upon to assist. Medical officers also handled preventive health before port visits, including vaccination checks and malaria precautions.

Why World War II submarines often sailed without doctors
Small crews and covert operations kept doctors on larger ships or submarine tenders, while surface-ship medical officers also handled emergency response and preventive health.
