South Korea has developed bombs equipped with global positioning system (GPS) capable of targeting distant enemies day and night. The Agency for Defense Development (ADD) and 20 defense firms have jointly developed the 225-kilogram guided bomb to improve combat capabilities of fighter jets. The Korea GPS-guided bomb shows that South Korea is capable of developing a weapons system for its fighters with its own technology. The GPS-guided bombs to be installed in fighter jets can hit enemies 24 hours a day, hidden behind obstacles at long range. Some of the bombs were deployed from late last year for a test run. The advanced weapon system is expected to allow aged combat jets, including F-4 and F-5 jets, to better strike intended targets as far as 100 kilometers away.
