Wrecked destroyers USS Downes and USS Cassin in their docks, with WW1-vingatage "super dreadnaught" battleship, USS Pennsylvania in the background, in dry dock at Pearl Harbour following the Japanese attack.   

"Downes" and "Cassin" were effectively destroyed by fire as a result of a "common hit" from a Japanese incendiary bomb.  However, the critical damage was to their hulls, and recovery of their internal equipment and installations allowed them to be recommissioned  later in the war.  USS Pennsylvania continued in active service to the end of the war, finally going to the bottom as a firing target in 1948.  Best regards, JR.

After Pearl Harbour ...

"Yorktown" class USS Enterprise (left) and USS Yorktown (right) under construction in dry dock at Newport News Drydock Company, 1937.  The US was not, in fact, particularly forward in adopting aircraft carriers.  They may have felt somewhat inhibited by the Washington Naval Treaty, and ongoing efforts towards international naval disarmament.  Not totally inhibited, however, since they commissioned three "Lexington" class and one "Ranger" class carriers between the late-1920s and early 1930s.  The collapse of the international naval treaty system in 1935 (following the repudiation of its naval treaty obligations by Japan) gave urgency to the process of strengthening the US carrier force.  The immediate response to this was the "Yorktown" class, purpose-built carriers that built on experience gained with the "Yorktown" class and the USS Ranger.  Three "Yorktown" class carriers were produced; two (Yorktown and Hornet) were destroyed by enemy action in 1942.  The USS Enterprise survived the war (with difficulties) and was eventually broken up in 1958.  Of course, the USS Enterprise, in a sense, continues to Go Where No Man/Person Has Gone Before ... Live Long and Prosper, JR.

Naval rearmameent - "Yorktown" class carriers.

The Shaw with a temporary bow fitted together with parts from other ships. She then proceeded to Mare Island under her own power to have a new bow attached.
