The South Korean military remains on high alert after two unmanned aerial vehicles recently infiltrated Korea's air defense zones undetected.
We have our national defense correspondent Kim Hyun-bin standing by at the Ministry of National Defense in Seoul to tell us more on the military's plans to make sure such incidents don't happen again.
Korea's defense minister Kim Kwan-jin acknowledged Friday that the military lacks the capability to detect small-sized aircraft like the unmanned aerial vehicles that were recently found on South Korean soil.
Kim said that if North Korea were to develop their technology, theyd' be capable of sending the drones with explosives or chemical weapons attached.
But he stressed that the two drones that crashed recently were not capable of loading explosives.
The ministry added that North Korea has hundreds of UAVs in its arsenal, and that they are very difficult to detect because they're so small.
As such, the South Korean military plans to purchase low-altitude radar systems and other military equipment to prevent an infiltration of Korea's air defense network.
The ministry believes one of the drones, the one found north of Seoul in the city of Paju late last month, malfunctioned and crashed as it was headed back to North Korea.
They added that the aircraft had flown at one point over the presidential office for 20 seconds and a Japanese-made Nikon camera attached to it took around a hundred and 90 pictures.
South Korea's defense ministry also announced today that they successfully test-launched a ballistic missile that can target key facilities in North Korea. What is the latest on that?
The ministry says the test on March 23rd of its 500-kilometer ballistic missile was successful, and that it has the capability to hit any and all strategic targets in North Korea, including key nuclear and military facilities.
This missile can hold up to one ton of explosives and is expected to be included in South Korea's combat arrangements starting next year.
The South Korean military currently has missiles with a range of 300 kilometers that can hold 500 kilograms of explosives in its arsenal, so this successful test represents an upgrade.
The focus now turns to developing a ballistic missile with a range of 800 kilometers that can hold up to a 500 kilogram warhead. Back to you Conn-young.
