In the case of the system mentioned in the 2003 Air Force report above, a tungsten cylinder impacting at has a kinetic energy equivalent to approximately . The mass of such a cylinder is itself greater than , so the practical applications of such a system are limited to those situations where its other characteristics provide a clear and decisive advantage—a conventional bomb/warhead of similar weight to the tungsten rod, delivered by conventional means, provides similar destructive capability and is far more practical and cost-effective.
