Top Air Force commander oversees first test flight of S. Korea's KF-21 advanced supersonic fighter

The Korean Air Force Chief of Staff took part in the first test flight of the country's homegrown advanced KF-21 supersonic fighter jet known as Boramae earlier today.

General Lee Young-su assessed the aircraft's operational capabilities while flying at an altitude of 4-thousand-5-hundred meters over waters off the country's southern coast at a speed of more than one-thousand kilometers per hour.

Following the flight he claimed Boramae would stand shoulder to shoulder with world-class fighter jets.

South Korea began developing its own jet in 2015 and the first batch is scheduled to be deployed to front line air bases starting next year.
