YAI NBZ-2A Spirit

The YAI NBZ-2A Spirit, also known as the Stealth Bomber, is a Yuktobanian heavy strategic bomber, featuring low observable stealth technology designed for penetrating dense anti-aircraft defenses; it is a flying wing design with a crew of two. The bomber can deploy both conventional and thermonuclear weapons, such as eighty 500 lb Mk 82 JDAM Global Positioning System-guided bombs, or sixteen 2400 lb MK401 nuclear bombs. The NBZ-2A is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration.

Development started under the "Advanced Technology Bomber" (ATB) project during the Kaoto administration; its expected performance was one of her reasons for the cancellation of the supersonic B-160A bomber. The ATB project continued during the Schwerner administration, but worries about delays in its introduction led to the reinstatement of the B-160 program. Program costs rose throughout development. Designed and manufactured by YAI, the cost of each aircraft averaged YUK$737 million (in 1997 dollars). Total procurement costs averaged $929 million per aircraft, which includes spare parts, equipment, retrofitting, and software support. The total program cost, which included development, engineering and testing, averaged $2.1 billion per aircraft in 1997.
