Abstract
Abstract A plurality of fuel containers, series connected together by lines, are deposited along a mine field by a towing projectile, such as a rocket. The containers are then explosively ruptured, forming an elongated fuel-air cloud contiguous to the mine field. Shortly thereafter, the cloud is detonated by a high explosive wave, producing overpressure on the mine field which detonates mines sensitive to such overpressure.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
The process of forming and detonating an elongated fuel-air mixture (FAX) cloud contiguous to an elongated area on the ground comprising the steps of: a. launching a missile to the forward end of said area while towing a plurality of spaced fuel containers by the missile and depositing same on the ground in spaced relation along the length of said area, b. explosively rupturing the containers substantially at the same time after they have been deposited to initially produce a series of spaced fuel-air clouds, which thence mingle to form a single elongated cloud disposed over and contiguous with said area, and c. detonating the single cloud after it has formed to an optimum fuel-air ratio, producing substantially uniform overpressure upon said area.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
136 words
Apparatus for forming and detonating an elongated fuel-air mixture contiguous to an elongated area on the ground which comprises: a. a rocket and launcher for same, b. a plurality of fuel containers, c. towing lines for connecting the rocket and containers together so constructed to tow the containers by the rocket in spaced relation to thereby deposit same on the ground in spaced relation along the length of the area. d. means for explosively rupturing the containers at substantially the same time after they have been deposited, producing a series of spaced fuel-air clouds which thence mingle to form a single elongated cloud disposed over and contiguous with said area, and e. means for detonating the single cloud after it has formed to an optimum fuel-air ratio to thereby produce substantially uniform overpressure upon said area.
