Crewmembers in a Rigid Hu
Crewmembers in a Rigid Hull Inflatable Boat (RHIB) wait for the right wave so they can ride it up onto the hull of the submarine so the submarine crew can unload the supplies and passengers.

The Japanese fishing vess
The Japanese fishing vessel "Ehime Maru" is lifted from the ocean floor by the Rockwater 2 to a shallow-water recovery site off the coast of Honolulu. In this photo, the "Quest" electric work-class remotely operated vehicle (ROV) observes the wreckage. The Ehime Maru went down off the coast of Honolulu, Hawaii, after a collision at sea with the submarine USS Greeneville (SSN 772). U.S. Navy Photo.

SSN688(I) - San Juan Clas
Function: Nuclear powered Fast Attack submarine.
History: The Los Angeles class SSN design proved to be so effective that as time progressed and technological improvements were made to the submarine's systems, rather than build a completely new class of boat it was decided to reuse the Los Angeles design, but fitted with newer, more advanced systems. Based on research and development studies, performed in part by USS Memphis (SSN691) which had been specifically modified during refit to serve as a technology test bed, several major improvements were made to the basic Los Angeles design. In addition to internal upgrades to improve the submarine's sensors and to make it quieter, the hull was also modified to increase submerged speed. Furthermore, by strengthening the sail and moving the forward dive planes from the sail to the bow, the San Juan boats have a true "under ice" capability. The Improved Los Angeles (or San Juan class) submarines currently fill the role of America's front line fast attack submarine, surpassing the Los Angeles class in all respects, and will continue to serve until replaced by either the Seawolf class (SSN21) or the Virginia class (SSN774).
