USS Coronado (LCS-4) is a modern American ship designed to operate in coastal or littoral waters. The keel of this vessel was laid in June 2009, the vessel was launched in 2012, and she entered service with the US Navy in April 2014. The length of the ship is 127.4 meters, with a maximum width of 31.6 meters! Full displacement reaches 3,100 tons, and the maximum speed is definitely more than 40 knots and probably fluctuates around 45-47 knots.
USS Coronado (LCS-4) is the second Independence-class ship. The ship of this type, like the Freedom type units, was created as a peculiar aftermath of the US accession to the so-called the war on terror after September 11, 2001 and the terrorist attack on USS Cole in October 2000. Independence-class ships were created as ships with the highest possible maximum speed and high maneuverability, which are to operate in coastal waters. Setting these criteria as the superior ship manufacturer (General Dynamics concern) decided to use a rare trimaran system, i.e. a unit with three rigidly connected hulls. However, this is a controversial solution if we take into account the increased hydrodynamic resistances. On the other hand, the very large width allowed to create a spacious landing site for helicopters and other aircraft, as well as to arrange a hold in the stern part, allowing the operation of smaller vessels. USS Coronado (LCS-4), shortly after entering service, successfully presented the possibilities of cooperation with US Marine Corps, as well as light helicopters. The cooperation with the MQ-8B Fire Scout drone was probably subjected to extensive testing on the ship at the end of 2014. In 2016, the USS Coronado (LCS-4) took part in naval maneuvers in the Pacific
