Japan's Maritime Self-Defense Force took delivery of the biggest warship since World War II, the Izumo, a helicopter carrier as big as the Imperial Navy aircraft carriers that fought the United States in the Pacific in the 1940s.

The 19,500-metric-ton destroyer, measuring 248 meters in length and 38 m wide, allows five helicopters to take off and land simultaneously.

It can carry up to 14 helicopters.
