Ingalls Shipbuilding president Brian Cuccias said: “Thousands of shipbuilders worked tirelessly to ensure the successful delivery of this highly capable warship.

“We are pleased to continue working closely with the navy to deliver exceptional ships using the highest safety and quality standards.”

The ship is designed to support  MV-22 tilt-rotor and F-35B Joint Strike Fighter aircraft.

USS Tripoli is also capable of conducting multiple mission operations, including humanitarian, disaster relief, maritime security and antipiracy.

Additionally, the ship features an enlarged hangar deck and JP-5 fuel capacity to provide air support.

With a displacement of approximately 44,971t, the US Navy’s 844ft-long LHA 7 can cruise at top speeds of more than 20k.

It is equipped with a fuel-efficient gas turbine propulsion plant, zonal electrical distribution, and electric auxiliary systems.

In October last year, Tripoli concluded its acceptance trials in the Gulf of Mexico.

LHA 7 programme manager Bryan Williams said: “The LHA team is proud to witness the delivery of the 15th large-deck amphibious ship built at Ingalls.

“The completion of the Tripoli is a great complement to our longstanding legacy of building state-of-the-art warships.”

Currently, Bougainville (LHA 8), the guided-missile destroyers Delbert D Black (DDG 119), Frank E Peterson (DDG 121) Lenah H Sutcliffe Higbee (DDG 123), Jack H Lucas (DDG 125), and amphibious transport dock ships, Fort Lauderdale (LPD 28) and Richard M McCool Jr (LPD 29) are being built at HII’s Pascagoula shipyard.

Last week, HII conducted a second builder’s sea trials of the US Navy’s Delbert D Black (DDG 119) destroyer.
