A validation was conducted on the air defense artillery (ADA) section of the Joint Exercise Support System (JESS) model version 1.1. The data base contains weapon characteristic values that are producing invalid results. The Pk values for the ADA systems need to be degraded and the rounds per burst for the guns need to be decreased. Errors in the JESS 1.1 code are also producing invalid results. 1. The range degradation factors for ADA weapons are not being correctly applied. Consequently, long-range ADA weapons are allowed to fire at aircraft flying nap of earth (NOE). 2. Helicopters flying at NOE are more vulnerable than helicopters flying at 200 feet above ground level. 3. The definition of altitude band boundaries in the data base is not consistent with the code logic used to determine the altitude band and used to select the Pk which is dependent upon altitude. This results in erroneous data being supplied to the data base. Providing some consistency in the definition of these altitude bands would aid the people who supply Pk data based upon aircraft altitude. 4> The code allows aircraft to fly below ground level. This results in negative training and unintended protection to aircraft since ADA weapons will not fire at aircraft flying below a minimum altitude. (sdw)
