In order to study the defense strategy for gunship against small caliber High-Explosive(HE) munition, the vulnerability model of gunship under the attack of small caliber HE munition was established and the vulnerable area of gunship in typical strike directions was calculated. The bottom of the gunship was divided into several regions and the defense effectiveness of these regions was calculated.According to the calculation results, the vulnerable area of gunship attacked from the lower-right back direction is 6.97 m2, which exhibits the highest vulnerability. Considering the shape of the gunship, its bottom and sides need to be defended on the top of priority. The defense effectiveness of the two regions that contain front and back fuel tanks is higher than 50%, which means that these regions should be priorly defended if the mass of armor is limited. Adding the clapboard between the mainbody and the tail of the gunship can prevent the fragments spreading in the lateral direction after explosion of projectile, which leads to the defense effectiveness improving from 2.93% to 11.07%, compared with direct defense of the tail region of gunship.
