The test took place at the Permanent High Explosive Testing Grounds of the White Sands Missile Range in the state of New Mexico, for which 4744 tons of ANFO explosive (ammonium nitrate and fuel oil), equivalent to 4 kilotons of TNT, were used to roughly simulate the effect of an eight kiloton air-burst nuclear device. With a total energy release of about 17 TJ (or 4.2 kilotons of TNT equivalent), Minor Scale was reported as "the largest planned conventional explosion in the history of the free world", surpassing another large conventional explosion, the "British Bang" disposal of ordnance on Heligoland in 1947, reported to have released 13 TJ of energy (about 3.2 kilotons of TNT equivalent).
