Assessment of Selected Cannons according to the Probability of Target Destruction

Anotace: The article discribes combat effectiveness of aircraft automatic cannons and compares combat effectiveness of M61A1 rotary cannon with cannons being used on aircraft of the Czech Air Force. The procedure and examples of probability calculation for aerial target destruction are presented for hight rate of fire weapons firing one burst. The procedure is shown for a step law and an exponential law of target destruction and for the constant and changing target hit probability. Basic characteristics for all types of rapid-firing cannons which are part of standard armament of modern aircraft are included in this paper.
