The government plans to purchase and develop interceptors to counter North Korea's evolving missile threats. 

The Defense Acquisition Program Administration(DAPA) said on Monday that its defense project promotion committee held a meeting and approved five major defense projects.

The projects include a plan to buy shipborne Standard Missile-6(SM6) interceptors from the United States for South Korean Navy's KDX-III Aegis destroyers. 

The DAPA committee approved 770 billion won for the procurement project that will run from this year through 2031. 

The agency also approved a project to purchase an additional batch of F-35A stealth fighters. 

The three-point-75 trillion won project will buy some 20 more F-35A fighters by 2028, increasing the number of the stealth fighters operated by the South Korean Air Force to over 60.
