United States Navy

The United States Navy was one of five branches of the United States Armed Forces.

Military operations
During the 2066 Anchorage Campaign, the USS Ebon Atoll was accidentally fired upon and sunk by the USS Interference via nuclear torpedo strike, with all hands lost. The event was considered one of the most tragic disasters in U.S. naval history since World War II.

Naval fighters were responsible for coastal patrols and defense, as well as recovery of enemy vessels captured near American shores. In certain cases, the Navy would also cooperate with intelligence agencies such as the DIA in counter-espionage operations.

Intelligence and counter-intelligence
Like other branches of the United States military, the Navy was involved in a number of illicit activities. The foremost of these was domestic surveillance, carried out using black sites like Sugar Grove, where Naval analysts and operatives monitored U.S. citizens for seditious activity. Appalachia was an example of what defined sedition: anything that could affect the war effort, including unionization, anti-automation protests, striking, and of course, the Free States. Those who caught the eye of the Navy faced a fate worse than death: Edgar Aarsen, a union activist, was marked for surveillance in March 2075. A year later, he was abducted ("arrested"), murdered, and his children put up for adoption.

The Navy did have successes in counter-intelligence that didn't involve abuse of its own citizens: The extensive surveillance campaign also turned up a number of leads that almost compromised the Chinese espionage network set up under the cover of Mama Dolce's Food Processing in Morgantown.

Technology
The Navy experimented with advanced technologies. The facility at Sugar Grove in Appalachia included radiation removal, electromagnetic pulse weapons, and highly advanced holotapes capable of storing entire mainframes thanks to highly advanced compression algorithms (Project Siphon). The Navy also used the Nuka-Cola Corporation as a proxy to test various chemical concoctions, via the Kanawha Nuka-Cola Plant testing programs.

The Somnus Initiative was carried out at the Sugar Grove black site, where abducted United States citizens were brainwashed to act as sleeper agents for the United States government. The project had mixed success.
