Some days ago, the former and incumbent officers of the air force of the south Korean army handed over confidential military information to the Lockheed Martin Company, the U.S. military monopolies. It contained the "plan of establishing joint weapons system" dealing with the introduction of important weapons and arms buildup of the air force in different periods from 2012 to 2026, the plan of purchasing JASSN, etc..

JASSN is a new type advanced weapon designed for a precision air attack on ground target. The south Korean air force has been busy to introduce this weapon since the Yonphyong Island shelling last year. One shell costs 700,000 U.S. dollars.
