SEOUL - A US-made surveillance drone Global Hawk arrived at a South Korean military base on Monday.

A spokesperson for South Korea's Defense Ministry announced the delivery at a news conference on Monday. But the spokesperson didn't mention any details.

South Korea's Yonhap News Agency reported that the large drone is the first of four aircraft that Seoul plans to introduce in the first half of 2020.

The agency said the aircraft landed at an air force base in Sacheon on southern tip of the Korean Peninsula and is preparing for deployment.

The Global Hawk is equipped with infrared sensors and radar that can seek and monitor targets on the ground, even at night or in bad weather.

South Korea plans to strengthen its monitoring of North Korea, which has repeatedly launched ballistic missiles. Pyongyang is expected to oppose Seoul's introduction of the surveillance drone.
