Fincantieri’s shipyard in Muggiano on Friday delivered Paolo Thaon di Revel, the first of seven new Multipurpose Offshore Patrol ships (PPA – Pattugliatore Polivalente d’Altura) for the Italian Navy.The 143-meter-long PPAs are built at the Integrated Shipyard of Riva Trigoso and Muggiano, with deliveries expected until 2026. They are part of the renewal plan of the operational lines of the Italian Navy vessels, approved by the Government and Parliament and started in May 2015 (“Naval Act”) under the aegis of OCCAR (Organisation Conjointe de Cooperation sur l’Armement…

Introducing a new class of warship can be fraught with pain, and the first ship is always the hardest – almost always behind schedule and over budget. And trying something new and transformational is even harder.The U.S. Navy knows this from experience. That’s one reason why the Navy is opting for a lower risk design for its next class of guided missile frigates (FFGs).Just about every new class has experienced a rough start. Although the USS Arleigh Burke-class of guided missile destroyers (DDGs) today represent the largest and most successful class of warships…

The U.S. Navy commissioned USS Tripoli (LHA 7) Wednesday without the typical fanfare and traditional public commissioning ceremony due to public health and safety restrictions on large public gatherings amid the conronavirus pandemic.Delivered in February, USS Tripoli is the U.S. Navy's second America-class amphibious assault ship built by Huntington Ingalls Industries’ (HII) Ingalls Shipyard in Pascagoula, Miss. The warship was commissioned administratively and transitioned to normal operations…

Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division delivered the newest America-class amphibious assault ship USS Tripoli (LHA 7) to the U.S. Navy on Friday. Tripoli will be commissioned later this year before sailing to its homeport of San Diego.Amphibious assault ships project power and maintain presence by serving as the cornerstone of the amphibious ready group or expeditionary strike group. These ships transport elements of the Marine expeditionary unit or Marine expeditionary brigade with a combination of aircraft and landing craft.

Following the drawdown at the end of the Cold War, the Navy finds itself trying to build up again. The expansion of Russian and Chinese naval power has changed the calculus. While there will always be a debate about the final number of ships to build, we can all agree on one thing: the Navy must get bigger and the demand signal is to start building now,” said Chief of Naval Operations Adm. John Richardson, in testimony before Congress regarding the sea service’s 2019 budget request.

As Congress wrestles with the budget, there is at least a bipartisan consensus that defense spending should grow, and that includes growing the Navy’s fleet. The current goal is 355 ships, an admirable goal, but an objective that faces many cost hurdles. The surface fleet (which excludes submarines and aircraft carriers) needs to grow in capability and capacity. The numbers of ships being procured or envisions would increase as the total n umber of ships increases, but the number in this story represents current program status.

GE's Marine Solutions division said it has shipped a LM2500 marine gas turbine propulsion module that will help power the U.S. Navy's 75th DDG Arleigh Burke-class destroyer Jack H. Lucas (DDG 125).

The US Navy will christen its newest America-class amphibious assault ship, the future USS Tripoli (LHA 7), during a 10 a.m. CDT ceremony, Sept. 16, in Pascagoula, Mississippi. Thomas Dee, performing the duties of the Under Secretary of the Navy, will deliver the ceremony's principal address. Lynne Mabus, the wife of the 75th Secretary of the Navy, the Honorable Ray Mabus, will serve as the ship's sponsor. The ceremony will be highlighted by Mrs. Mabus breaking a bottle of sparkling wine across the bow to formally christen the ship, a time-honored Navy tradition. "When USS Tripoli, the newest America-class amphibious assault ship, joins the fleet, we'll be a stronger, more flexible, and better Navy and Marine Corps team," Dee said.

GE’s Marine Solutions said its LM2500 family of aeroderivative marine gas turbines have been selected to power two newbuild surface combatants for U.S. Navy and Coast Guard programs. Specifically, two LM2500+ gas turbines will power Bougainville (LHA 8), the U.S. Navy’s newest multi-purpose amphibious assault ship. Construction is expected to begin shortly according to shipbuilder Huntington Ingalls Industries. GE LM2500+ gas turbines also power first-in-class USS America (LHA 6) and Tripoli (LHA 7).

GE's Marine Solutions reports that the Japan Maritime Self Defense Force (JMSDF) commissioned its second Izumo-class helicopter-carrying destroyer. The new JS Kaga (DDH 184) is powered by four GE LM2500 marine gas turbines, and was commissioned at the Japan Marine United Corporation shipyard in Yokohama on March 22, 2017. First-in-class JS Izumo (DDH 183) and JS Kaga are the largest surface combatants in the JMSDF fleet. Both feature a powerful and reliable combined diesel and LM2500 gas turbine propulsion system, with the gas turbines using GE’s integrated electronic controls.

GE’s Marine Solutions has announced that the seventh multi-purpose Italian FREMM frigate Federico Martinengo, was launched on March 4. The ceremony was held at Fincantieri’s Riva Trigoso shipyard in Genoa, Italy. All of the Italian Navy’s new Carlos Bergamini-class  FREMM frigates (10-ship program) feature the same power dense GE LM2500+G4 gas turbine in a COmbined Diesel eLectric And Gas turbine (CODLAG) propulsion system. In addition to the Italian FREMM frigates, the DCNS shipyard in Lorient…
