37mm Rounds

What Are 37mm Rounds?

37mm rounds are launcher-based cartridges designed for use with compatible 37mm signaling devices and smooth bore launchers. These cartridges are commonly used for smoke deployment, visual signaling, training applications, and specialty launcher functions.

Unlike 40mm destructive device systems, many 37mm platforms are classified and sold as signaling devices when paired with compliant ammunition configurations. Always verify compatibility and local regulations before use.
