Retired US Navy Iowa Class Battleship preserved in Camden NJ as a museum and memorial. She is docked on the Delaware River across from Philadelphia PA, where she was originally built. With at least 4 different commissions she served her country in the South Pacific in World War II, during the Korean and Vietnam Wars, and off Lebanon, the Persian Gulf, and Central America in the 1980s. She is one of the most decorated ships in US Navy history. I have included a link to her history if you wish to learn more.

This mid ships pictures show her original secondary armament of dual 5"/38 caliber DP guns.
It also shows the three primary weapon systems added her reactivation in the 1980s - the Mk 15 20mm Phalanx Close In Weapon System, Harpoon Anti Ship Missiles, and Tomahawk Cruise Missiles - the latter available in both Conventional and Nuclear tipped Land Attack Versions as well as an Anti Ship Version.
