USS Florida (BB-30) was an American battleship (dreadnought), the keel of which was laid in March 1909, launched in May 1910, and was completely completed in 1911. The total length of the ship at the time of launching was 159 m, width 26.9 m, with a full displacement of about 23,400 tons. The maximum speed, on the other hand, did not exceed 21 knots. The unit was armed with: 10 305 mm guns, 16 127 mm guns and 4 57 mm guns. USS Florida (BB-30) was the first of two Florida-class battleships. Units of this class were slightly enlarged compared to the Delaware class, the units had almost identical armor and armament. The Florida class, on the other hand, was the first in the history of the US Navy to use a steam turbine as a drive entirely and from the very beginning. USS Florida (BB-30) was built at the New York Naval Shipyard in New York. After entering service, she took an active part in the actions against Mexico in 1914 in the Veracruz area, and after the US entered World War I, she was sent to Scapa Flow to strengthen the Royal Navy. From this base, it carried out patrol tasks in the North Sea or protected convoys going to Norway, but did not take an active part in the fight. The unit remained in service after 1918, and in the years 1924-1926 it underwent a thorough modernization, consisting mainly in the complete replacement of the propulsion system. USS Florida (BB-30) was retired from active service in 1931 and sold for scrap that same year.
