North Korea has test fired a new weapon carrying a "powerful warhead", state media reported.
The hermit state's leader, Kim Jong-un, has described it as as an "event of very weighty significance".
The missile is not thought to be a long-range ballistic warhead capable of striking the United States.
Kim personally oversaw the testing of the new type of tactical guided weapon, state media reported.
It is North Korea's first public weapons test since the second US-North Korea summit in Hanoi ended with no agreement earlier this year.
State news agency KCNA did not describe exactly what the weapon is, including including whether it was a missile or another type of weapon, but "tactical" implies a short-range weapon, as opposed to the long-range ballistic missiles that have been seen as a threat to the United States.
Nevertheless, the weapon has a "peculiar mode of guiding flight" and "a powerful warhead", KCNA said.
Kim said "the completion of the development of the weapon system serves as an event of very weighty significance in increasing the combat power" of the North Korean army, according to KCNA.
