Major design changes include a larger flight deck, improvements in weapons and material handling, a new propulsion plant design that requires fewer people to operate and maintain, and a new, smaller island that has been pushed aft. Improvements were made through developing technologies and more efficient design. With these constraints in mind, the US Navy developed what was initially known as the CVN-21 program, which evolved into CVN-78, Gerald R. As a 2005 Rand report said, "The biggest problems facing the Nimitz class are the limited electrical power generation capability and the upgrade-driven increase in ship weight and erosion of the center-of-gravity margin needed to maintain ship stability." The Nimitz design has accommodated many new technologies over the decades, but it has limited ability to support the most recent technical advances. Ford arrived at Naval Station Norfolk after seven days of builders trials in April 2017. The endurance of the Nimitz class is exemplified by USS Theodore Roosevelt, which spent 159 days underway during Operation Enduring Freedom without visiting a port or being refueled. Displacing about 100,000 tons when fully loaded, a Nimitz-class carrier can steam in excess of 30 knots (56 km/h 35 mph), cruise without resupply for 90 days, and launch aircraft to strike targets hundreds of miles away. The current Nimitz-class aircraft carriers in US naval service have been part of United States power projection strategy since Nimitz was commissioned in 1975. Director of Operational Testing Michael Gilmore has criticized the assumptions used in these forecasts as unrealistic and has indicated sortie rates similar to the 120/240 per day of the Nimitz class would be acceptable. These ships are intended to sustain 160 sorties per day for 30-plus days, with a surge capability of 270 sorties per day. Ford-class carriers will have a reduced whole-life cost due in part to reduced crew size. The biggest visible difference from earlier supercarriers is the more aft location of the island (superstructure). The ability to carry up to 90 aircraft, including the Boeing F/A-18E/F Super Hornet, Boeing EA-18G Growler, Grumman C-2 Greyhound, Northrop Grumman E-2 Hawkeye, Lockheed Martin F-35C Lightning II, Sikorsky SH-60 Seahawk helicopters, and unmanned combat aerial vehicles.Stealth features to reduce radar cross-section.A new nuclear reactor design (the A1B reactor) for greater power generation.An Electromagnetic Aircraft Launch System (EMALS) in place of traditional steam catapults for launching aircraft.Kennedy (CVN-79) the AN/SPY-6 will replace the AN/SPY-4 as the volume search component of the system.

The new vessels have a hull similar to the Nimitz class, but introduce technologies since developed with the CVN(X)/CVN-21 program, such as the Electromagnetic Aircraft Launch System (EMALS), as well as other design features intended to improve efficiency and reduce operating costs, including sailing with smaller crews. Ford replacing Enterprise (CVN-65), and then eventually taking the place of the existing Nimitz-class carriers. The class, with a planned total of ten ships, will replace the Navy's current carriers on a one-for-one basis, starting with the lead ship, Gerald R. Ford class is a class of nuclear powered aircraft carriers currently being constructed for the United States Navy.
