Diesel electric submarines without snorkels must surface to charge their batteries. The ideal is to do this at night and run submerged all day while patrolling an area where targets might be present. Sometimes the boat would remain surfaced even in daylight where the threat of enemy aircraft was minimal to do the full charge. This image is of a US submarine on the surface doing a battery charge in the early morning. It is near an island or headland perhaps lying in wait for a convoy or keeping watch for enemy shipping that would be reported.
