The Salvage of Pearl Harbor: Up She Rises
In Part Two of this documentary, take a closer look at the salvage efforts on the three battleships that were outright sunk in the attack on Pearl Harbor that would eventually be returned to service.
As 1942 began work was now continuing a pace on getting the ships back afloat and into dock. The first good news in this regard was West Virginia.
She'd settled upright and so divers estimated that if the various holes could be patched and pumping done in a sensible order from the top down she should just rise back up to the surface on an even keel, which in turn meant that a lot of the initial work on removing her main battery could now be stopped.
This in turn would save a lot of time and effort both in actually removing the guns now and later on in reinstalling the guns once the ship was ready for sea again.
Instead work could be redoubled on cleaning and preserving the guns in place and getting various smaller holes patched ready for the lift.
In the process of this they also managed to recover what was left of one of the torpedoes that had struck the ship which gave some of the base's weapons officers something to study.
