The second in a series of scale-model wind tunnel tests to determine the effect of fuselage mounted stores on the drag of an attack aircraft is reported. Variations of wing position, wing sweep, and store loadings were investigated over an angle of attack range of -2 to 6 deg and a Mach number range of 0.60 to 0.90. In general, the high wing configuration had lower incremental drag than the low wing and variation of wing sweep had negligible effect. Increasing the longitudinal spacing between stores tended to increase the incremental drag due to the stores. Staggering the store load, increasing the lateral spacing, or shielding the forward row of bombs had little effect on the incremental drag. The magnitude of the incremental drag from fuselage mounted stores does not appear to be hidden when it is measured on a high drag airplane model, nor does it appear to be magnified when measured on a low drag airplane model.
