“Two weeks ago, Japan commissioned its largest naval vessel since the end of World War II. Sleek and with the clean lines of a ship designed for stealth, JS Izumo pulled into Yokosuka Naval Base, her new home port, and officially joined the Maritime Self Defense Force… Officially, she’s a “helicopter destroyer” — a destroyer designed to carry helicopters. But Izumo is no ordinary destroyer. Destroyers are not 800 feet long nor do they displace 24,000 tons. They also don’t have a flight deck that runs the entire length of the ship, aircraft hangars, and the capability to embark up to 14 helicopters.”
