The USS F-2 was originally named Barracuda, but was renamed prior to her launching in March of 1912. F-2 was launched by the Union Iron Works out of San Francisco, California and was sponsored by Miss A. R. Rolph. She was commissioned in June 1912 with Lieutenant F. L. Chew in command.



F-2 operated with the 1st Submarine Group, Pacific Torpedo Flotilla in the waters between San Diego and San Pedro. F-2 was an integral part in both developing tactics and coordinating the use of undersea craft during extended training periods in the Hawaiian Islands. These operations occurred from August 1914 until November 1915.

F-2 remained in commission in ordinary at Mare Island until June 1917, and was a flagship of Division 1, Submarine Force, Pacific Fleet. Afterward she returned to operations, running out of San Pedro where she executed both surface and submerged exercises. F-2 also implemented torpedo proving practice and experiments in balancing at various depths, as well as training prospective submarine crew members.


F-2 was placed in reserve commission on September 1919 at San Pedro in order to be used for elemental school work before being decommissioned at Mare Island in March of 1922. F-2 was sold in August of that same year.

Asbestos in Navy Ships

Although an essential component of the naval fleet, especially throughout conflicts of the last century, submarines also pose a lasting health risk to soldiers serving on them. However, these risks extend beyond the inherent dangers that existed while operating the vessels during military conflicts. Unfortunately, products containing asbestos were also common aboard submarines because of the material’s high resistance to heat and fire. Despite its value as an insulator, asbestos fiber intake can lead to several serious health consequences, including mesothelioma, a devastating cancer without cure. Furthermore, the enclosed environment of submarines put servicemen at an even higher risk of exposure. Current and former military personnel who came into contact with or served on submarines should seek immediate medical attention in order to detect possible health consequences associated with asbestos exposure.
