USN

U.S. Navy

The USN stands for the United States Navy, which is the naval warfare branch of the United States Armed Forces. It is responsible for conducting operations at sea, on land, and in the air to protect and defend the United States and its interests. The USN operates a vast fleet of ships, submarines, and aircraft to carry out its missions around the world. It plays a crucial role in maintaining national security and projecting American power globally.

The US Navy Radiological Defense Laboratory (NRDL) was established in 1946 at the Hunters Point Naval Shipyard in San Francisco, California. Its primary mission was to study the effects of nuclear weapons and to develop methods for radiological decontamination of naval vessels and equipment. The NRDL played a significant role in analyzing radioactive contamination from atomic tests and in advancing radiological safety procedures for the fleet. The laboratory was deactivated in 1969 as its functions were absorbed by other military organizations and due to changing defense priorities.
