What research or testing has been done to launch long-rod projectiles at near-hypersonic or greater speeds while causing the projectile to impact a target lengthwise?

The Defense Systems Information Analysis Center (DSIAC) is seeking information on technologies, methodologies, and processes that can be used to launch long-rod projectiles at 3 kft/s or greater, resulting in the projectile impacting lengthwise on a target surface perpendicular to the projectile’s line of flight.  Of primary interest are methodologies, test procedures and results, and reports that document successes and failures.

Long-rod testing is imperative to increasing fidelity in threat response modeling.  The ability to perform this testing will help pinpoint threat delivery systems that can meet testing requirements and help reduce experimental testing.

The long rods are typically made of a metallic material and ~6 and 10 inches long, have a maximum diameter of ~0.19 inches, and weigh between 200 and 500 grains.  Research and/or testing to launch rods of any material type with a length-to-diameter/width ratio between 30:1 and 80:1 at the speeds of interest and impact a target lengthwise would also be of interest.

If you have any information on applicable technologies, methodologies, testing, analysis, etc., please provide details in the attached form here or in an e-mail to Scott Armistead (scott.e.armistead.ctr@mail.mil), the lead DSIAC analyst on this effort, or join the discussion on the DoDTechipedia forum by clicking the “Join the Discussion” button below.
