Boarding the fast-attack 688 Los Angeles / SSN-class USS Honolulu in Pearl Harbor, O'ahu, Hawaii.


At the sail (conning tower); note other SSN moored just aft. That one is a newer 688i model with the forward diving planes on the bow instead of on the sail.

On the USS Honolulu's bow, looking forward. Frigates in background.



View of the helm and dive stations which are just forward of the port periscope.

Ohio-class (USA):      New Summary Video! (11.6 MB, WMV)

the boats [18 built]


Was 8 C-4's (Pacific) and 10 D-5's (Atlantic), but now the C-4's have been converted. Four went to the D-5 configuration, and the other four serve other special missions as SSGN's (1) (2) (3) (4) -- technology demonstrators to deploy SEALs, fire Tomahawks, and other such systems to have been incorporated into batch 2 of the Virginia-class NSSN's [see lower section].


Upon completion of the four C-4 boat conversions to the D-5 configuration, the new total of 14 D-5 SSBN's were redistributed between the two oceans (most likely 7 x 7).
