This report covers measurements of the pressure distribution around the body of the Mk 25 Torpedo equipped with a shroud ring tail) and includes studies of the effect on the pressure distribution of variations in yaw and pitch angles, velocity, and static pressure (i. e., submergence) The tests were made on a 2-inch diameter model (model scale 1 to 11.2). In addition to providing a general picture of the pressure distribution as affected by the different variables) the data presented herein are useful in determining the best locations and arrangements for the pressure intakes to the immersion mechanism and to the depth and roll recorder) and also as a check on cavitation measurements. Because the pressures on the fins themselves were not measured in these tests, the data cannot be used to calculate overall forces acting on the complete torpedo.
