In the coming years, the U.S. Navy has plans to update its fleet with a new line of aircraft carriers to replace the aging Nimitz-class. Along with these, there are a series of other ships and submarines that are just now entering service for the U.S. Navy. The process of building a ship and commissioning it for use in the service is a multiyear process, and the bigger that these projects are, the longer they can take. (These are the American warships and submarines with the biggest crews.)

A couple of the newer classes entering service are the Arleigh Burke-class destroyers and the Virginia-class submarines. The Constellation-class is an entirely new class of warship being introduced to the U.S. Navy as well. Here, 24/7 Wall St. is taking a closer look at the newest ships to join the Navy.

To determine the U.S. Navy’s newest warships, 24/7 Wall St. reviewed the military data site World Directory of Modern Military Warships’ directory of all active ships in the U.S. and cross-referenced with data from the Naval Vessel Register. We compiled data on all ships and submarines — 30 in total — that have been commissioned in the service of the U.S. Navy for five years or less and ranked them by age. It should be noted that this list is current as of July 2024.

For the U.S. Navy, the Nimitz-class carriers are starting to age out, as most are 30 years and older, and the U.S. is replacing them with the newer Ford-class supercarriers. The newest is the Gerald R. Ford which entered service in 2017. Going forward, the Navy is planning to replace the Nimitz carriers on a one-for-one basis for Ford-class carriers as they slowly age out.

Currently, the U.S. Navy is composed of destroyers which account for about 30% of its naval fleet. Submarines come in a close second in terms of allocation, making up about a quarter of the fleet. Beyond this, a fleet of cruisers followed by littoral combat ships and amphibious assault support ships accounts for the rest of the naval vessels. (These are the 20 strongest navies on Earth, compared.)

Here is a look at the 30 newest ships to enter the U.S. Navy:

Why Are We Covering This?

Knowing the most recent ships and submarines to enter the U.S. Navy is important for understanding the state of national security in the United States. Also the Navy is primarily how the United States projects power across vast distances and maintains a secure balance within the global community.
