Congressman Jody Hice Visits NSWC Dahlgren Division. The congressman - who was briefed by NSWCDD engineers on electromagnetic launchers and hypervelocity projectiles - observed the launcher fire a projectile in a demonstration. Hice also watched a laser weapon demonstrated during briefings on directed energy weapons and development. Throughout his tour of NSWCDD facilities, Hice saw the command's capability to develop and integrate complex warfare systems, including the ability to incorporate electric weapons technology into existing and future fighting forces and platforms.
