This yellow submarine is used as a target for torpedo testing by the US Navy and its contractors. It is unmanned and towed into place when needed.

At the same dock is the US Navy’s only operational diesel-electric, deep-diving, research and development submarine, the USS Dolphin.

Employed by both civilian and Navy activities, Dolphin is equipped with an extensive instrumentation suite that supports missions such as acoustic deep-water and littoral research, near-bottom and ocean surveys, weapons launches, sensor trials, and engineering evaluations. [wikipedia link]

USS Recruit (TDE-1 and TFFG-1) in San Diego, CA, the Navy’s first non-ship, was originally a commissioned vessel and observed traditional Naval shipboard procedures like all other vessels.

Affectionately known as USS Neversail, the Recruit was a two-thirds scale mock-up and served as an instructional platform for new recruits. When completed in 1949, it was 225 long, had a 24-foot, four inch beam and a 41-foot mast.

Today, with the closure of the Navy training station the Recruit is being preserved as an historical building. [quarterdeck.org]

The Enrico Toti was the first Italian submarine to be built after World War II.  She was commissioned in 1968 and decommissioned in 2001 after which she was sailed up the Po River to Cremona, Italy. There she sat until August of 2005 when engineers transported her across land to the “Museo della Scienza e Della Tecnica” in Milan.

Here is the same sub after its move to Milan.

Calypso is the name of a ship that Jacques-Yves Cousteau, one of the most important researchers in oceanography, equipped as a mobile laboratory for field research.

A barge accidentally rammed Calypso and sank her in 1996. She was raised, and eventually towed to the basin of the Maritime Museum of La Rochelle in 1998, where she was intended to be an exhibit. A long series of legal and other delays kept any restoration work from begining. As of the end of 2006, most of the equipment has been removed from her upper decks, and she sits open to the elements. It is unclear as to what will become of this historic vessel. [wikipedia]
