Controversy and competency is the best way to describe the first variable geometry combat aircraft to enter operational service anywhere in the world. This was the F-111 Aardvark, the typical Cold War 'below the radar' strike bomber. It was born in one of the most politically-motivated and incompetent procurement processes ever, and experienced a troublesome gestation period with spiralling costs in development and production, and an unimpressive first deployment to Vietnam in 1967.et, all this was forgotten when the F-111 matured and proved itself to become a devastating weapon and a formidable penetration strike aircraft in its second tour in Southeast Asia in 1972-73, helping to prove that its sophisticated attack and terrain-following radar systems enabled the delivery of a large number of ordnance with unerring accuracy at ultra-low level in a hostile environment.
