Many present-day naval vessels, aside from aircraft carriers and full-length deck amphibious assault ships, are capable of carrying aircraft. A majority of United States Navy ships have at least a helipad, capable of landing medium-sized helicopters. Many others have decks and even hangars incorporated into the structure of the ship. It has become a standard part of modern ship design to have a deck that supports multiple, medium or large helicopters, as well as being able to house them in a hangar, for protection and maintenance. Aside from carriers and full-length deck amphibious assault ships, the US Navy has 12 classes of commissioned surface warships, 10 of which are aviation-capable. Two of those classes, patrol ships and mine counter-measure ships, are due to be replaced by the littoral combat ship, at which point the entire US Naval surface war fleet will be aviation-capable. US Navy ships As of 2016, the current types and classes of US Navy ships, along with their capabilities are as follows: Along with these types and classes, many of the US navy's non-commissioned ships, specifically those of the Military Sealift Command, are aviation-capable as well. The United States Coast Guard also has cutters that are aviation-capable. Also, with the growing technology in UAVs and UCAVs, virtually every ship afloat has, or will soon have, some type of aviation capability.
