The Nimitz-class aircraft carriers, which resemble floating fortresses of unrivaled strength, stand for the might of the US Navy. The flagship of naval fleets since its introduction in 1975, the Nimitz class is able to deliver airpower anywhere in the world without relying on nearby bases. These enormous nuclear-powered ships, which were built by Newport News Shipbuilding, can run for more than 20 years without needing to refuel.

They have a more than a thousand-foot-long flight deck that can accommodate about ninety aircraft, ranging from fighter planes to helicopters. These carriers, which have sophisticated radar systems and an abundance of defensive weapons, act as both an overwhelming force and a deterrent, solidifying American maritime dominance for many years.
3. Stealth fighter F-117 Nighthawk
Joined the Service in 1983
Producer: Lockheed
Price: *$111 million
The F-117 Nighthawk, the first operational stealth aircraft in history, changed the face of aerial combat when it was originally introduced in the 1980s. Its angular, faceted form was groundbreaking, scattering radar waves and making it practically invisible to opposing defenses. It was developed by Lockheed Martin's covert Skunk Works division.

The Nighthawk was not a conventional fighter because it lacked air-to-air weapons, but it was excellent at carrying out targeted attacks against valuable targets and was often able to sneak past highly developed air defense systems. Its recognizable silhouette—which resembled a flying arrowhead—became a symbol of the American military's technological advancements. The F-117 was retired in 2008, but its reputation as a pioneer in stealth technology lives on.
