South Korea's Peace Krypton reconnaissance aircraft system is a militarized version of Raytheon's Hawker 800XP, reclassified as an RC-800 Hawker, a mid-size, twin-jet corporate aircraft that has been refurbished into a tactical and intelligence platform.
The RC-800's primary mission is to conduct both geospatial and signals intelligence. They are located at the Seoul Air Force base.
In March, the country paid almost $200 million to Lockheed Martin to upgrade its 32 F-16 aircraft to purchase Mode 5 Identification Friend or Foe and Link 16 Tactical Datalink.
