An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, one has yet to successfully land on one. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increase the time of availability on the combat zone.
The Type II U-boat was designed by Nazi Germany as a coastal U-boat, modeled after the CV-707 submarine, which was designed by the Dutch dummy company NV Ingenieurskantoor voor Scheepsbouw Den Haag (I.v.S) and built in 1933 by the Finnish Crichton-Vulcan shipyard in Turku, Finland. It was too small to undertake sustained operations far away from the home support facilities. Its primary role was found to be in the training schools, preparing new German naval officers for command. It appeared in four sub-types.
Blohm+Voss (B+V), also written historically as Blohm & Voss, Blohm und Voß etc., is a German shipbuilding and engineering company. Founded in Hamburg in 1877 to specialise in steel-hulled ships, its most famous product is the World War II battleship Bismarck. In the 1930s its owners established the Hamburger Flugzeugbau aircraft manufacturer which, shortly before the outbreak of World War II, adopted the name of its parent company. Following a difficult period after the war, B+V was revived, changing ownership among several owners, as Thyssen Group and Star Capital. In 2016 it became a subsidiary of Lürssen and continues to supply both the military and civil markets. It serves two areas: new construction of warship as NVL BV & Co. KG and new construction and refit of mega yachts. The company has been in operation, building ships and other large machinery, almost continuously for 145 years.
USS Dolphin (SF-10/SC-3/SS-169), a submarine and one of the "V-boats", was the sixth ship of the United States Navy to be named for that aquatic mammal. She also bore the name V-7 and the classifications SF-10 and SC-3 prior to her commissioning. She was launched on 6 March 1932 by the Portsmouth Navy Yard, sponsored by Mrs. E.D. Toland, and commissioned on 1 June 1932 with Lieutenant John B. Griggs, Jr. in command.
USS Macon (ZRS-5) was a rigid airship built and operated by the United States Navy for scouting and served as a "flying aircraft carrier", designed to carry biplane parasite aircraft, five single-seat Curtiss F9C Sparrowhawk for scouting or two-seat Fleet N2Y-1 for training. In service for less than two years, in 1935 the Macon was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as the USS Macon Airship Remains on the U.S. National Register of Historic Places.

The Freccia-class destroyer was a class of destroyers built for the Regia Marina in the 1930s. Four modified ships were built and delivered in 1933 for Greece.
USS Puritan, a civilian transport built by Craig Shipbuilding Company in Toledo, Ohio, was launched in 1901, and lengthened by 26 ft (7.9 m) in 1908. The ship sailed on the Great Lakes in passenger service, was purchased by the U.S. Navy at the end of the war, and returned to passenger service after the war. The ship sank in 1933 near Isle Royale in Lake Superior, and its wreck is listed on the National Register of Historic Places.

USS Leedstown (AP-73), built as the Grace Line passenger and cargo ocean liner SS Santa Lucia, served as a United States Navy amphibious assault ship in World War II. The ship had first been turned over to the War Shipping Administration (WSA) and operated by Grace Line as the WSA agent from February to August 1942 in the Pacific. In August the ship, at New York, was turned over to the Navy under sub-bareboat charter from WSA. She was sunk 9 November 1942 off the Algerian coast by a German submarine after German bombers caused damage the day before.
