What Does SCUBA Stand For?

The acronym SCUBA stands for “Self-Contained Underwater Breathing Apparatus.”

A Brief History of SCUBA

During World War II, the development of underwater warfare and sabotage required a new generation of highly trained divers capable of operating for extended periods underwater. To accomplish this, the US Navy established the Office of Strategic Services Maritime Unit (OSSMU) and tasked them with developing new underwater technologies to support these operations.

One of the key developments was the creation of the oxygen rebreather, which allowed divers to recycle their exhaled breath, thereby extending their time underwater. This technology was critical for underwater sabotage and demolition missions, as it enabled the dave divers – “frogmen” – to work quietly and undetected for extended periods.

The first successful oxygen rebreather was developed by Dr. Christian Lambertsen in 1941, and it was referred to as the Lambertsen Amphibious Respirator Unit (LARU). This rebreather system allowed frogmen to breathe underwater using a small compressed oxygen tank and a carbon dioxide scrubber. It was also highly portable, allowing frogmen to move quickly and easily through the water.

As the use of oxygen rebreathers became more widespread, the term SCUBA was coined to refer to these closed-circuit breathing sets. The acronym stands for “Self-Contained Underwater Breathing Apparatus,” which accurately describes the rebreather technology used by frogmen during World War II.
