South Korea shows off new jet fighter as its arms sales surge

South Korea unveiled its newly developed fighter, the KF-21, at a defense exhibition in Seoul. The fighter, designed for deep strikes into adversarial territories, is seen as a more affordable alternative to Lockheed Martin’s F-35. South Korea plans to use the fighter for its military and also sell it overseas. South Korea’s defense exports have been increasing, with major buyers including countries that rely on aging Russian weaponry.
