Always remember to put them up clean

If ever there was a lesson in why you should store your guns in good condition, here we see the Iowa-class battlewagon, USS New Jersey (BB-62), as she was put to pasture after her WWII service.

The Sailors are removing the muzzle seals from two of her forward turret’s 16″/50cal Mark 7 guns, while she was being reactivated at the Naval Supply Depot, Bayonne, Oct. 1950, for use in Korea.

New Jersey, of course, would go back into retirement following Korea, only to be recommissioned a third time for Vietnam, and a fourth in the 1980s to help the Reagan-era 600-ship Navy make weight.

New Jersey gets her barrels back

New Jersey just received three of her historic 16-inch gun barrels that have been stored at Norfolk for more than a half-century.

The 16-inch/50-caliber Mark 7 guns, each weighing 237,000-pounds, were first installed on the USS New Jersey when she was built at the  Philadelphia Navy Yard in the 1940s. While she used them to good effect in the Pacific and off Korea, the worn barrels were replaced by new tubes, which the battleship still has, and the old wartime vintage barrels placed in storage at Norfolk Naval Shipyard’s St. Juliens Creek Annex for the past 60 years. Now, after a $200,000 fundraiser to move three of the 66-foot long guns from Virginia to Camden, New Jersey, the old battleship has some of her original teeth back.
