DID YOU KNOW?

Swim calls on US Navy vessels are a longstanding tradition, allowing sailors to enjoy a break and swim in the open ocean. This practice dates back to at least World War II and involves sailors jumping off the ship into the water for relaxation and morale-boosting. The activity often occurs in calm, warm waters and can be accompanied by additional leisure activities like cookouts.

Safety measures during swim calls include posting armed guards, such as sharpshooters, on the ship or in rigid-hulled inflatable boats to watch for sharks and other potential dangers. Crew members take turns jumping from the ship, often using aircraft elevators that lower them closer to the water to reduce the risk of injury from high jumps.

Swim calls can involve various Navy vessels, from submarines to aircraft carriers.
The latter offers a dramatic experience due to their size and height above the water.
 
This tradition allows sailors to unwind during long deployments and is often considered a highlight of their service time.
