High performance 30 mm and 50 mm gun systems are used
in fundamental and applied studies of projectile and target performance. Tests to evaluate
the ballistic performance of advanced tungsten-alloy long-rod, kinetic energy projectiles
against RHA, NATO Triple Heavy, ceramic laminates, and reactive targets are conducted.

These figures illustrate a computer simulation of an
L/D-10 tungsten-alloy projectile striking a steel target at 1.5 km/s. Results 2
microseconds after the initial impact are shown. The tungsten-alloy projectile is shown in
red, the steel target is shown in green (left), and pressure contours are depicted in the
center photo. At right, shear stresses develop in regions where adiabatic shear bands are
observed in finite-thickness targets.
