Naval Amphibious Base (NAB) Coronado is a significant shore command of the U.S. Navy, located in Coronado, California. The base was officially commissioned in January 1944 and was established in 1943 from the dredging of San Diego Bay to allow large ships used in World War II to steam into Naval Station San Diego.

The base is approximately 1,000 acres in size and is situated on the Silver Strand, between San Diego Bay and the Pacific Ocean. It serves as the West Coast focal point for special and expeditionary warfare training and operations and provides a shore base for the operations, training, and support of naval amphibious units on the West Coast.

NAB Coronado is home to over 30 tenant commands with a population of approximately 5,000 personnel. Major commands include Commander, Naval Surface Force Pacific (COMNAVSURFPAC), Commander Naval Special Warfare (SPECWAR) Command, and the Commander Expeditionary Warfare Training Group (EWTG) Pacific.

The base is also the home of the Navy’s Sea-Air-Land (SEAL) Team and houses the famed Navy Parachute Team, the Leap Frogs. The base and its adjacent beaches are a critical habitat for the Western Snowy Plover and the California Least Tern. The Navy conducts an active predator control program on Coronado’s beaches to protect nesting birds.
