Shoulder-launched Multipurpose Assault Weapon

4D supports the Naval Surface Warfare Center’s (NSWC) Densified Propellant for Shoulder-launched Multipurpose Assault Weapon (DP-SMAW) development initiative. 4D supports rapid prototyping activities associated with the DP-SMAW test and evaluation and provides range support services to ensure the test fixtures and test enclosures are maintained in a continuous state of availability.

The DP-SMAW effort supports the Marine Corps’ need to provide a fire from enclosure (FFE) capability to the warfighter that meets the length, weight, and sound pressure level requirements for shoulder-launched weapons. To reduce the concussive effects of firing a SMAW from enclosed spaces, the Marine Corps is developing and evaluating alternative propellants and system designs that will result in minimal changes to the SMAW size and weight while retaining or improving the warhead penetration capabilities.
