- Typical configurations use a 32-round drum and require a stable mounting platform for accurate fire.
- Variants and upgrades over time have improved reliability, safety features, and ease of maintenance in varied environments.
- Effective teamwork with the Mark 19 Grenade Launcher involves coordination with spotters and proper loader handling to avoid delays.
- Operational use emphasizes safe handling, proper fuze selection, and awareness of blast and fragmentation risks in urban contexts.
Mark 19 Grenade Launcher: Specs
Key specifications for the Mark 19 Grenade Launcher vary by model, but common characteristics include:
- Caliber: 40x53 mm grenades
- Feed system: Belt-fed from a drum, typically around 32 rounds per drum (some configurations use alternative drums)
- Rate of fire: Generally in the range of 260–400 rounds per minute depending on feed and operator control
- Weight (platform dependent): Roughly 60–75 kg depending on mounting and accessories
- Effective range: Range varies by round and fuze, generally several hundred meters for point targets and longer for area targets; maximum ranges can extend to roughly 2 km with suitable rounds
History of the Mark 19 Grenade Launcher
The Mark 19 Grenade Launcher began development in the 1960s as a response to the need for a reliable automatic 40mm launcher capable of sustained fire in diverse combat situations. It entered service in the late 1960s to early 1970s and quickly earned a reputation for delivering heavy, area-dense fire against fortifications, light armor, and entrenched positions. Over the years, multiple modernization efforts added improved feeding reliability, enhanced safety interlocks, and simpler field maintenance. The history of the Mark 19 Grenade Launcher reflects a balance between firepower, platform flexibility, and ease of use that kept it relevant on a range of vehicles, aircraft, and ground emplacements for decades.
Usage and Deployment
In practice, the Mark 19 Grenade Launcher is used to create suppression, saturate areas, and deny terrain to opposing forces. It is commonly mounted on light and medium vehicles, helicopter hardpoints, and tripod systems for ground teams. Operators coordinate with spotters and vehicle crews to manage rate of fire and target selection while maintaining safe loading procedures. Because 40mm grenades produce blast and fragmentation, attention to blast radius, friendly positioning, and safe fuze settings is essential in urban and confined environments.
Maintenance & Safety Considerations
Maintenance focuses on regular inspection of the feed mechanism, bolt operation, and proper cleaning to prevent jams. The Mark 19 Grenade Launcher requires careful handling due to its weight and recoil characteristics, and it benefits from secure mounting to minimize movement during firing. Safe operation hinges on clear communication, proper target assessment, and adherence to standard range safety practices.
