The ship, the first of two for the coast guard, is designed to operate in open seas and will be used for search-and-rescue, fire-fighting missions and to control illegal immigration as well as for more complex naval missions.
Fincantieri said the ships have a top speed of 18 knots, a range of more than 3,000 miles and a length of more than 300 feet.
The crew complement will be 38 people.
Features include four fast rigid-hulled inflatable boats for emergency response and other missions and a helicopter landing pad.
"The ships are also equipped with sophisticated command and control systems and latest-generation radar able to find and follow surface marine pollution and they will have a large stern door to let vehicles enter and be transported on a large working deck," the company said.
"The real forte of these patrol boats is their innovative hybrid propulsion system, involving an auxiliary diesel-electric engine for use at the low and very low speeds needed when performing surveillance and control missions for long periods."
