ANALYSIS: N Korea's Kim speaks softly, shows off new military might

SUBMARINE MISSILE

North Korea also unveiled what appeared to be a new submarine-launched ballistic missile (SLBM), labelled the Pukguksong-4.

"If the new SLBM is intended to be deployed, it may be intended for the new conventionally powered ballistic missile submarine that North Korea hinted at building in July 2019," analysts at 38 North, a U.S.-based think tank, said in a report.

At least some parts of the missile’s motor case appeared to be filament-wound, which would reduce the missile’s structure weight and allow greater range and payload capability, the report said.

CONVENTIONAL WEAPONS

The parade featured what appeared to be new or updated weapons for North Korea's conventional military, one of the largest in the world.

The North displayed rows upon rows of multiple launch rocket systems and short-range ballistic missiles that were heavily tested over the past year.

"My biggest concern was the solid-fuel, short-range tactical missiles that North Korea had focused on developing over the past year or so," said Chun Yung-woo, a former South Korean nuclear negotiator.

The parade also displayed new mobile air-defence radar vehicles and what appeared to be an entirely new tank with anti-tank missiles and smoke grenade launchers more closely integrated into the design than previous imported models.
