Abstract
A sonobuoy may be designed for operation in the Arctic. The review explores available literature in order to examine the feasibility of placing the sonobuoy under the ice by means of a kinetic energy penetrator. Two different methods are used to predict the performance of different penetrator configurations. The first involves the use of an equation originally developed by the Sandia Laboratories for soil penetration, and the second the development of a new equation based on assumptions which simplify the mechanism of penetration. The agreement between the two methods is quite good. Ballistic calculations are performed to estimate impact velocities and angles for an air-dropped projectile. Final conclusions indicate that the concept of an air-dropped, ice-penetrating sonobuoy deployment system is quite feasible, provided certain design and launch requirements are maintained. None of these limitations seem to be impractical. TRUNCATED
