By far, United States tops the list of the strongest navies in the world in 2017 rankings and will continue to do so in foreseeable future. The core of the U.S. Navy consists of the fleet of mighty aircraft carriers and amphibious assault ships that give it unparalleled force projection capabilities. Nimitz class supercarriers represent the pinnacle of technological advancement, yet they are already scheduled to be replaced by the new Ford class, even more sophisticated vessels. The lead ship of the class, USS Gerald R. Ford (CVN-78) is currently in trials, awaiting commission sometimes in 2017. With more than 75 aircraft on deck, the new carrier is more powerful than many air forces around the world. Add new Zumwalt class destroyers and 75 nuclear-powered submarines, plus numerous and well-trained naval aviation, and it is easy to see why the United States Navy is the most powerful navy in the world.
