The USS John F. Kennedy CVN 79 isn't just another boat. Honestly, calling it a boat might get you some dirty looks from the sailors at Newport News Shipbuilding. This is a 100,000-ton floating city. It's the second installment in the Ford-class saga, and if the USS Gerald R. Ford was the "beta test," the Kennedy is where things get real.
People talk about carriers like they’re relics of the Cold War. They aren't. Not even close.
When you look at the silhouette of the USS John F. Kennedy CVN 79, it looks familiar. That flat top. The island. But underneath that steel skin, the guts of this ship are 21st-century tech that would make a Silicon Valley engineer sweat. We're talking about a move away from steam—the stuff that powered the Industrial Revolution—to pure electricity. It’s a massive shift.
The Electromagnetic Leap
For decades, if you wanted to launch a fighter jet off a deck, you used steam catapults. It was violent. It was loud. It was incredibly hard on the airframes. The Kennedy swaps those old pistons for the Electromagnetic Aircraft Launch System, or EMALS.
Think of it like a railgun for airplanes.
Instead of building up massive pressure in pipes, EMALS uses a linear induction motor. This allows the ship to launch a wider variety of aircraft. You can flick a light drone off the deck or hurl a fully loaded F-35C into the sky with the same system. It’s adjustable. It’s smoother. And more importantly, it requires fewer people to maintain.
But it hasn't been easy. The Ford had its share of "growing pains" with EMALS. Software glitches. Hardware failures. The Navy has been under a microscope for these delays. Critics like those at the Government Accountability Office (GAO) have frequently pointed out the cost overruns. But the Kennedy is benefiting from all those hard-learned lessons. By the time CVN 79 hits the fleet, the "bugs" are expected to be features.
Why the Island Moved
If you look at a photo of the old Nimitz-class carriers and then look at the USS John F. Kennedy CVN 79, you’ll notice something weird. The island—that tower where the captain sits—is further back. It’s also smaller.

This wasn't an aesthetic choice.
By pushing the island toward the stern, the Navy created more "acres" of usable deck space. It’s basically a massive reorganization of a workshop. Now, planes can land, refuel, rearm, and get back into the fight much faster. The Navy calls this the "pit stop" concept. It’s modeled after NASCAR. They want to increase the Sortie Generation Rate (SGR) by about 33% compared to older ships.
Efficiency kills. In a high-end conflict, the ability to get more planes in the air every hour is the difference between winning and, well, not.
Digital Guts and the Power Grid
The Kennedy is basically a giant battery. While the Nimitz class used steam to turn almost everything, the CVN 79 uses electricity. We’re talking about a nuclear power plant that generates three times the electrical capacity of previous carriers.
Why so much juice?
- Future-proofing. The Navy is looking at directed-energy weapons. Lasers. If you want to shoot down incoming missiles with a beam of light, you need a lot of power.
- A-R-E-S. The Advanced Arresting Gear (AAG) also runs on electric motors. It catches the planes coming in. It's digital, so it can self-diagnose problems.
- Dual Band Radar. The Kennedy was originally supposed to have a different radar setup, but they pivoted to the Enterprise Air Surveillance Radar (EASR) to save money and weight. It's more capable than the old rotating dishes.
There’s a common misconception that these ships are "sitting ducks." People say long-range Chinese missiles like the DF-21D make carriers obsolete. It’s a popular talking point. But a carrier is never alone. It’s the center of a Strike Group. It has destroyers, cruisers, and submarines surrounding it like a shield. Plus, the USS John F. Kennedy CVN 79 can move at over 30 knots. Finding a moving target in the middle of a vast ocean and hitting it is significantly harder than a YouTube comment section makes it sound.
Construction Secrets at Newport News
Building a ship like this is basically playing Lego with 500-ton blocks. They call them "supershifts."

At Huntington Ingalls Industries, they used 3D digital modeling for the first time on the Kennedy. Instead of thousands of paper blueprints that get greasy and torn, workers used tablets. This sounds small. It isn't. It allowed them to catch structural interferences before they even cut the steel.
Actually, the Kennedy was launched (floated out) ahead of schedule in late 2019. It’s the outfitting—the miles of wiring and the complex weapon elevators—that takes the time. Those Advanced Weapons Elevators (AWE) use magnets instead of cables. On the Ford, they were a nightmare. On the Kennedy, they’ve been refined to ensure that bombs get from the magazine to the flight deck without a hitch.
What’s in a Name?
The legacy of the name "John F. Kennedy" carries weight. This is the second carrier named after the 35th president. The first, CV-67, was a legendary conventionally powered ship. Veterans of the "Big John" are fiercely protective of the legacy.
The new Kennedy, CVN 79, is the bridge to the future.
It’s designed to last 50 years. Think about that. A sailor born today might serve on this ship in the year 2045. A captain born in 2030 might command it in 2070. That kind of longevity requires a design that can be upgraded. You can't just rip out steam pipes easily, but you can swap out servers and software.
The Cost of Power
Let’s talk money. It’s expensive. Roughly $13 billion.
There’s no way to sugarcoat that. It’s a massive investment of taxpayer dollars. Defense experts like those at the Center for Strategic and Budgetary Assessments (CSBA) often debate if we should buy two smaller carriers for the price of one Ford-class.

But a smaller carrier can't do what the USS John F. Kennedy CVN 79 does. It can't carry the same variety of aircraft. It doesn't have the same "staying power." It’s the difference between a Swiss Army knife and a sledgehammer. Sometimes, you just need the sledgehammer.
The Kennedy is also designed to be operated by nearly 600 fewer sailors than a Nimitz-class ship. Over 50 years, that’s billions in savings on salaries, housing, and healthcare. The automation isn't just for show; it’s a fiscal necessity.
What's Next for CVN 79?
Right now, the ship is undergoing finishing touches and testing. It’s a slow process. You don't just "turn on" a nuclear carrier. You test every valve. Every circuit. Every weld.
The delivery date has shifted a bit, with the Navy aiming for a mid-2025 delivery and a subsequent deployment after rigorous sea trials. This isn't a delay because of failure; it’s a delay because they are integrating the F-35C capabilities directly into the build, rather than doing it later as a "retrofit."
Smart move. Saves money in the long run.
Key Takeaways for the Future
- Watch the Sea Trials: The real test comes when the Kennedy hits the open Atlantic. Watch for reports on "cycles per hour" for EMALS.
- The Drone Factor: Keep an eye on how many MQ-25 Stingray drones are assigned to the Kennedy. This will be the first ship to truly lean into the "unmanned" era.
- Global Presence: When CVN 79 enters active service, it will likely replace an aging Nimitz-class ship, maintaining the 11-carrier fleet requirement.
If you want to understand the future of American power, don't look at the politicians. Look at the flight deck of the USS John F. Kennedy CVN 79. It’s where technology, physics, and sheer national will collide. It's a massive bet on the idea that the aircraft carrier remains the king of the ocean.
