- For much of their history submarines have spent most of their time on the surface, only submerging to make attacks.
- But the arrival of nuclear power allowed a submarine to stay underwater indefinitely.
- Operation Sandblast demonstrated to the world that submarines could now spend an entire patrol underwater.
In 1960, the U.S. Navy conducted a landmark exercise in the history of submarine warfare. The nuclear powered submarine USS Triton circumnavigated the globe completely underwater, proving that submarines—which until then had spent much of their time on the surface—could now operate completely submerged.
It was all thanks to nuclear energy, which provided unlimited power to submarines.
