U.S. Marines successfully removed and replaced an F-35B Lightning II LiftFan for the first time at sea aboard amphibious assault ship USS America (LHA 6) during the short-takeoff-and-vertical-landing (STOVL) variant’s third and final shipboard developmental test phase in November.

The F-35 Lightning II Patuxent River Integrated Test Force from Air Test and Evaluation Squadron (VX) 23 and personnel from Lockheed Martin observed as the Marine Operational Test and Evaluation Squadron (VMX) 1 Marines tested the LiftFan removal and replacement process. Prior to embarking America, the VMX-1 maintainers leveraged their experience in legacy AV-8B Harrier and F/A-18 Hornet squadrons while learning and testing land-based F-35B maintenance procedures.

As they conducted the first LiftFan swap at sea, the Marines accounted for and tracked each step of the process by entering the individual maintenance steps into ALIS, the Autonomic Logistic Information System, which equips personnel with the ability to plan ahead, maintain and sustain F-35 subsystems over the life of the aircraft.

Testing the ability to swap entire engines, engine components and LiftFans at sea proved the shipboard maintenance construct and provided critical hands-on experience dealing with the confined space and deck motion aboard ship—vital elements that cannot be replicated ashore.

Their testing also refined and improved the procedures, ensuring efficiency of future training and maintenance actions by fleet maintainers.

LoL I garentee you people will still be trying that argument for the next decade.

by "that argument" did you perhaps mean F-35 performance in so called dogfighting?

(am just trying to understand what you said)

Thank you for proving my point.

Huntington Ingalls Industries announced June 22 that the nuclear-powered aircraft carrier John F. Kennedy grew about 70 feet in length with the addition of the lower stern. The lower stern was lifted into place at the company’s Newport News Shipbuilding division, where the second Gerald R. Ford-class aircraft carrier is now 50 percent structurally complete.

Like Ford, Kennedy is being built using modular construction, a process where smaller sections of the ship are welded together to form larger structural units (called “superlifts”), equipment is then installed and the large superlifts are lifted into the dry dock using the company’s 1,050-metric ton gantry crane.

“This is a significant milestone in the ship’s construction schedule,” said Mike Shawcross, Newport News’ vice president, John F. Kennedy (CVN 79) and Enterprise (CVN 80) aircraft carrier construction. “We are halfway through lifting the units onto the ship, and many of the units are larger and nearly all are more complete than the CVN 78 lifts were. This is one of many lessons learned from the construction of the lead ship that are helping to reduce construction costs and improve efficiencies on Kennedy.”

After several days of preparations, the 932-metric ton lower stern lift took about an hour to complete, thanks to a team of about 25 shipbuilders — from riggers and the crane operator to shipwrights and ship fitters. The lower stern consists of 30 individual units and includes the ship’s rudders, steering gear rooms and electrical power distribution room. The carrier is on track to be completed with 445 lifts, which is 51 fewer than Ford and 149 fewer than USS George H.W. Bush (CVN 77), the last Nimitz-class carrier.
