(LEAD) N. Korea displays submarine-launched missile at military parade
(ATTN: UPDATES with new ballistic missile from para 3)
SEOUL, April 15 (Yonhap) -- North Korea on Saturday showed off what it claims to be a submarine-launched ballistic missile (SLBM) during a large-scale military parade in Pyongyang.
It marks the first time that the secretive communist nation has unveiled the new weapon apparently in development at such a public event.
A new intermediate-range ballistic missile (IRBM), which Pyongyang calls the Pukguksong-2, also appeared at the event.
The model, also known as a KN-15 missile, is an upgraded version of an SLBM.
In February, the North test-fired a Pukguksong-2 missile, which flew more than 500km into eastern waters, followed by Pyongyang's announcement that the launch was a "complete success."
