The NTTR integrates and provides support for test and training programs that have a direct effect on the war-fighting capabilities of the combat air forces.

Two of the group's members, Colonel John R. (Killer) Kane and First Lieutenant Donald Pucket were awarded the Medal of Honor for their actions in combat.

During the early years of the Cold War, the 98th Bombardment Wing (BW), Very Heavy was formed in 1947 and assigned to Strategic Air Command.

Wing combat missions in Korea included interdiction of enemy communications and support of United Nations ground forces.

[7] During the Korean War, the squadrons of the 98th flew more than 5,000 sorties and dropped more than 40,000 tons of bombs (actual total unavailable).

[citation needed] The wing remained at Yokota Air Base, Japan in combat-ready status for another year.

The wing's squadrons began receiving new Boeing B-47E Stratojet swept-wing medium bombers[7] in January 1955, capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union.

[citation needed] At this point the wing began an intensive training program to convert to combat ready status as soon as possible.

The wing's operational area included the Eastern Atlantic Ocean, most of Europe, North Africa and the Middle East.

In October 1976, the 306th Strategic Wing, based at Ramstein AB, West Germany assumed this support task and the 98th phased down at Torrejon and was inactivated 31 December 1976.

Its mission is to provide a flexible and realistic "battle space" to support training, testing, and tactics development, for which it controls the airspace over 12,000 square nautical miles, 7,000 of which are shared with civilian aircraft.

[4] In June 2011, the wing was redesignated Nevada Test and Training Range and its operational groups were replaced by directorates.
