North Korea has developed yet another weapon that can put most of Japan within striking distance, this one potentially capable of evading missile defenses and delivering a nuclear bomb to a large chunk of the archipelago.

The North announced Monday that it had test-fired “new-type, long-range” cruise missiles over the weekend, according to state-run media. The launches were the country’s first missile tests since March, when it fired off two short-range ballistic missiles.

The country’s official Korean Central News Agency said the new missile, which it called “a strategic weapon of great significance,” had traveled for nearly two hours over North Korean land and air, ultimately hitting targets 1,500 kilometers away.
