The flight details were similar to Japanese assessments announced by defence minister Yasukazu Hamada, who confirmed the missiles didn’t reach Japan’s exclusive economic zone.He, however, added that the second missile was possibly launched on an “irregular” trajectory, a term used to describe the flight characteristics of a North Korean weapon modeled after Russia’s Iskander missile, which travels at low altitudes and is designed to be maneuverable in flight to improve its chances of evading missile defences.The launch followed the return of the carrier, USS Ronald Reagan, to waters off the Korean Peninsula and occurred an hour after North Korea condemned the US for talking to the UN Security Council about Pyongyang’s “just counteraction measures” on joint South Korea-US drills, suggesting its missile tests are a reaction to the allied military moves.It was the sixth missile launch in 12 days and the first since North fired an intermediate-range missile over Japan on Tuesday, prompting joint South Korean and US missile drills in which one weapon crashed and burned.The launch was reported by South Korea’s joint chiefs of staff and the Japanese government."
