SEOUL, Sept. 5 (Xinhua) -- South Korea's navy on Tuesday conducted a massive live-fire drill in an apparent show of force following the Democratic People's Republic of Korea (DPRK)'s sixth nuclear test.

The navy's first fleet command carried the live-firing exercise in the eastern wasters, mobilizing a 2,500-ton frigate, a 1,100-ton patrol ship, 400-ton guided-missile battleships and 130-ton high-speed boats, according to local media reports.

The maritime drill came two days after the DPRK's claim that it had successfully tested a hydrogen bomb that can be loaded onto an intercontinental ballistic missile (ICBM).

South Korea's army and air force conducted a joint live-fire missile exercise in the East Sea on Monday in response to the DPRK's sixth nuclear detonation.

Meanwhile, the navy's third fleet command planned to hold a separate maritime exercise in the southern waters for four days from Wednesday.

The exercise would mobilize 10 battleships, including two 2,500-ton frigates, and submarine as well as P-3 maritime surveillance aircraft, Lynx multi-role helicopters.

Also involving the drill would be the air force's F-15K fighter jets and a CN-235 transport plane.
