Dive Dive

Dive Dive is a phrase commonly used in submarine operations and sometimes in scuba diving, signifying an immediate and urgent command to submerge the vessel or diver as quickly as possible. It is typically an order given to the crew when a hazardous situation arises, such as a sudden detection of an enemy vessel, the urgent need to evade an incoming threat, or the necessity to quickly change depth for tactical advantage or to avoid surface hazards. The phrase is intended to elicit an immediate and rapid response from all personnel on board, prioritizing the safety of the submarine and its crew or the individual diver. The order bypasses normal operating procedures, emphasizing the immediacy of the required action. The urgency is often reinforced through the use of klaxons or other alarm systems in conjunction with the verbal command.

The use of "Dive Dive" also appears colloquially in non-military contexts as an exclamation to quickly avoid something unpleasant or embarrassing.
