Abstract

This paper presents a comprehensive comparative analysis of three technologies for increasing the range of 155-mm artillery projectiles: Base Bleed (BB), Rocket-Assisted Projectile (RAP) with solid rocket motor, and Ramjet propulsion. The physical mechanisms of aerodynamic drag reduction, solid propellant composition, design features, and aeroballistic properties are examined. Using a formalized Cost Per Kill (CPK) effectiveness model, a quantitative comparison of seven modern 155-mm munition systems by cost/range/accuracy criteria is performed. It is established that hybrid BB+SRM systems achieve 60–76 km range and are optimal by cost/effectiveness criteria for current gun artillery. Ramjet projectiles represent the only technology capable of reaching 100–150 km without critical barrel erosion but require resolution of fundamental scientific and technical problems. A seven-level research task hierarchy for implementing hybrid long-range systems is proposed.
