Our picture shows the deck of one of the giants of the United States Navy, the battleship Pennsylvania, one of the largest and most powerful battleships afloat. The Pennsylvania is modern in every particular and its armament and equipment are so powerful as to make her a very effective fighting machine The Pennsylvania is one of the advanced types of sea-going battleships. At the beginning of the late war the United States Navy had 361 vessels ready for service, including twelve first-line battleships, twenty-five second-line battleships, nine armored cruisers, twenty-four other cruisers, seven monitors, fifty destroyers, sixteen coast torpedo vessels, seventeen torpedo boats, forty-f our submarines, eight tenders to torpedo boats, twenty-eight gunboats, four transports, four supply ships, one hospital ship, twenty-one fuel ships, fourteen converted yachts, forty-nine tugs, and twenty-eight minor vessels.
