North Korea[edit]In 1985, North Korea managed to circumvent US export-control barriers to purchase 87 civilian-type Hughes MD 500s from a West German export firm (the purchase was conducted covertly) before the US government learnt of the illegal action by North Korea and moved to stop further deliveries to the country. There are reports indicating that at least sixty of the helicopters delivered to North Korea were modified to serve as helicopter-gunships. As South Korea produces the MD 500 domestically (under license) for use by its own armed forces, the modified helicopters operated by North Korea were deemed useful in conducting covert or deceptive operations against South Korea (such as incursions past the border).[5]The modified MD 500 helicopters were finally revealed by North Korea and seen by the USA and European countries during North Korea's Victory Parade held on the 27th of July in 2013 in Pyongyang, to commemorate the 60th anniversary of the end of the Korean War in 1953. Images and analyses done regarding North Korea's MD 500 helicopters show that they have been modified significantly to serve as light attack helicopters, such as modification work on the helicopters for them to be mounted with Soviet-designed AT-3 Sagger anti-tank wire-guided missiles.[6]
