As proposed, the JFK will be powered by 2 x A1B (A = "Aircraft Carrier", "1" = 1st Generation, "B" = Bechtel Marine Propulsion Corporation) nuclear reactors which will provide for a straight line speed of approximately 30 knots in ideal conditions - exceptionally fast considering a vessel of this size. Use of nuclear power (a US Navy staple when compared to competing global carrier designs elsewhere) feature essentially unlimited operational ranges and are theoretically only restricted by the lifespan of the reactor itself which can span several decades (20 to 25 years possible before replacement is required). Compared to the previous A4W nuclear reactor series in use on the Nimitz-class, the A1B models sport a smaller profile, simplified construction and provides up to three times the energy output. This sort of propulsion allows the United States Navy to be called to any point in the world making America's Navy the most powerful on the globe.
Structurally, the JFK will follow suit with the original USS Gerald R. Ford and displace a listed 100,000 tons. Its running length will be 1,106 feet with a beam (length) measuring 134 feet and draught (height) of 39 feet. Like previous USN carrier offerings, the JFK will be given a primarily flat deck surface with only an island superstructure fitted to the starboard side. However, in the new configuration, the island superstructure will reside well-aft of midships, clearing the mid and frontal deck space for aircraft actions (newer European carriers are featuring twin island superstructures, a second tower to specifically handle aircraft management). Four Electromagnetic Aircraft Launch System (EMALS) catapults will be used in place of the traditional steam systems to launch up to four aircraft simultaneously (though the portside two catapults intersect one another and require a slight delay in launching one aircraft over the other). Two catapults will be featured at the bow with the remaining two at portside. Retrieval will be via a conventional angled return deck area with "advanced" arrestor hooks in place (requiring the incoming aircraft to feature an arrestor hook). The flight deck will be serviced by three main hangar elevators - two fitted along starboard and one along port - which will provide access to full-service hangars below including maintenance, repair, fuel and munitions. Up to 90 navalized aircraft (though typically 75) of various types (fixed-wing, rotary-wing, UAVs/UCAVs) will be supported at any one time. The complete deck surface area measures 1,092x256 feet which allows many different aircraft types to be used. Like other modern surface warships, the Kennedy will also feature radar reduction measures, either through special coatings or enclosed structures, to help minimize its profile to enemy tracking systems.
