context_page_description: Caio Duilio is a destroyer of the Italian Navy. She and her sister Italian destroyer Andrea Doria form the Andrea Doria class; in turn these two ships, and the French vessels Forbin and Chevalier Paul, belong to the Horizon class. Caio Duilio is marked by hull number D 554 according to NATO classification.
context_section_description: Caio Duilio is a multirole ship, with a bias towards anti-aircraft warfare (the ship is much more capable in this role than the older destroyers) and short and medium-range defence capabilities. She is also highly capable in anti-submarine and anti-surface warfare.
  The ship has been designed to take and operate with Rotary wing aircraft (AW101 and NH-90) of much higher performance and more autonomy than previous generation helicopters. The handling of wheeled helicopters on the flight deck is guaranteed up to sea state 6 by the semi-automatic Canadian system TC-ASIST of Indal Technologies committing to these operations a single operator.
  By type of ship and technology aboard Caio Duilio is able to cover a broad spectrum of maritime activities, ranging from high-intensity military operations to Maritime Security operations. The missions that the unit can perform are: 
  Escort role in an aircraft carrier battle group or naval convoy;
  Command and control of joint and combined maritime operations in all forms of aeronaval warfare;
  Naval Command in support or integrated in the National Air Defense organization;
  Relief operations in case of natural disasters, crisis response and humanitarian operations;
  Counter-piracy operations.
  The ship was designed to be as little detectable by radar as possible, by using stealth technology for the hull and superstructure. Sea-keeping in unfavorable weather conditions is granted by two pairs of stabilizers.
  The acoustic signature was also reduced with an appropriate choice of machinery and engineering solutions and verifying the intensity of the radiated noise, since the design phase. Equal attention has been directed in the infrared (IR) signature branch, by lowering the temperature of engine gases through coaxial exhausts.
