US Navy and industry engineers will soon begin additional work on the USS America amphibious assault ship to finalize the ship’s integration with the F-35B Joint Strike Fighter, marking a substantial milestone for the Navy as it prepares for the future of amphibious warfare.

The USS America, the first-in-class of a series of new amphibs for the Navy, recently returned home to San Diego from a seven-month deployment to the Pacific and Middle East. The ship, which went to Guam, Singapore and other strategic areas for missions and training, is now slated to begin an extensive series of Hull, Mechanical and Electrical repairs – and also receive “additional modifications to support F-35 Lighting II operations on board,” a BAE Systems statement said.

The modifications to the flight deck will be an extension of previous work done on the USS America to ensure that the weapons and sensors are synchronized with the Joint Strike Fighter and that flight deck can withstand the heat of the F-35B vertical take-offs-and-landings. Marine Corps Short Take off and Landing F-35Bs have already conducted extensive flight testing on board the USS America.

Navy engineers installed a new heat-resistant thermally sprayed non-skid, which is designed to prevent long-term heat damage to the flight deck and underlying structure, adding intercostal structural members below landing spots seven and nine, Navy officials have told Warrior Maven.

“With the added structure, these two landing spots will provide the capability to perform closely timed cyclic flight operations with the F-35B without overstressing the flight deck,” a Navy official familiar with the process previously told Warrior Maven.

Sensors, combat systems, radars and weaponry on board amphibs have also been going through a series of upgrades to better integrate with the F-35, service developers explain; also, some of the modifications may involve re-adjusting some of the ship’s antennas in order to allow for a clear flight path for the JSF.

America-Class Amphibious Assault Ships & F-35B

Much of the previous efforts to incorporate the F-35 with the USS America included going inside the ship and dropping lighting and ventilation and piping wiring and everything down far enough so new material can be installed and welded in place, senior Navy officials said.

America class ships are outfitted with a group of technologies called a Ship Self Defense System. This includes two Rolling Aircraft Missile RIM-116 Mk 49 launchers; two Raytheon 20mm Phalanx CIWS mounts; and seven twin .50 cal. machine guns, Navy statements say.

The second America-Class amphib, LHA 7 (USS Tripoli), was launched in May of last year; the ship incorporates a high-tech Navy ship-based computing network called Consolidated Afloat Network and Enterprise Services, or CANES, developers said.

The USS Tripoli is 844-feet long and 106-feet wide with a weight of more than 44,000 tons. A fuel-efficient gas turbine propulsion system brings the ship’s speed up to more than 20 knots, a Huntington Ingalls statement said.

The USS Tripoli will incorporate a gas turbine propulsion plant, zonal electrical distribution and fuel-efficient electric auxiliary propulsion systems first installed on the USS Makin Island, a Navy statement said.

The third America-Class Amphib, slated to emerge by 2024, features the return of the well deck.

F-35B Will Change Tactics and Procedures on Amphibs

Part of the challenge to F-35B integration is recognizing how its technologies will change concepts of operations, tactics and procedures; the F-35B is a very different aircraft than the Harrier jets it is replacing, Navy officials said.

Harrier jets, which also have the ability to conduct vertical take-off-and-landings, are multi-role jets primarily designed for light attack missions – such as quickly flying over land locations where Marines are forward deployed and providing close air support.

While the F-35B can perform these missions as well, the new Joint Strike Fighter brings a wide range of new sensors, weaponry and aviation technology to the Corps.

These F-35B sensors, which include a Distributed Aperture System placing cameras around the aircraft to provide a 360-degree purview as well as Electro-Optical Targeting Systems; these sensors, among others, will allow the F-35B to perform ISR missions as well as strike and ground support.

The C5I (command, control, communications, computers, collaboration) requirements for the F-35B will be very different than how the Navy operated the Harrier.

America-class amphibs can transport up to 3,000 sailors and marines, including elements of a Marine Expeditionary Unit, or MEU, designed for amphibious warfare. Amphibious technology on board the ship can include up to 60 HMMWs, Light Armored Vehicles, mortars, artillery and smaller Internally Transportable Vehicles, or ITVs, configured to drive into the back of an Osprey, Navy and Marine Corps officials described.

In total, America-Class amphibs are configured to house as many as 31 aircraft including 12 MV-22 Ospreys and the CH-53 Super Stallion, AH-1Z Super Cobra, UH-1Y Huey, F-35 B Short-take-off-and-landing Joint Strike Fighter and MH-60 Sea Hawk helicopter, Navy officials explained.
