SEOUL， Oct. 18 (Xinhua) -- South Korea's military is to mull the development of its own nuclear-powered submarine against what it calls the Democratic People's Republic of Korea (DPRK)'s nuclear and missile threats， local media reported on Tuesday.
Government officials and ruling Saenuri Party members held a meeting to enhance the country's defense capability against the DPRK's nuclear threat， where the party strongly asked the government to push for the development of its own submarine propelled by nuclear power.
An unidentified defense ministry official was quoted as saying at the meeting that the military would carefully weigh the call in consideration of military effectiveness， technical availability and military situations in neighboring countries.
Calls here for introducing its own nuclear-powered submarine emerged after the DPRK showed an advance in its technology of submarine-launched ballistic missile (SLBM).
Pyongyang test-fired a ballistic missile from a submarine off its east coast on Aug. 24， traveling some 500 km toward Japan. The flight distance surpassed the 300 km which Seoul's military regards as a success.
Top DPRK leader Kim Jong Un has reportedly ordered to build a couple of 3，000-ton submarines capable of carrying and launching ballistic missiles.
A completed SLBM technology would raise the DPRK's nuclear threat to a new level as it is very hard to detect and track a DPRK missile from a submarine moving secretly deep under the waters.
Even if South Korea successfully secures its nuclear-powered submarine， uncertainties would remain about its military effectiveness.
The South Korean submarine will be required to wait inside waters 10-20 km away from the DPRK's submarine base in order to strike its enemy submarine before it submerges into deep waters. Such submarine， which stays in waters of that distance， would be attacked easily by DPRK forces.
