💥 M30 Triple-Base Artillery Propellant
Product Introduction
M30 propellant is a triple-base artillery propellant combining nitrocellulose, nitroglycerine, and nitroguanidine. The addition of nitroguanidine as the third energetic component delivers significantly higher energy per unit mass than single-base or double-base propellants, while simultaneously keeping the flame temperature relatively low — providing both extended range and reduced gun-tube erosion.
The M30A1 variant is the standard fill for the M203 Red Bag Propelling Charge (Zone 8S), the maximum-zone charge for 155 mm artillery. M30-family propellants are also used in the BMCS M92 high-zone modules, larger-calibre howitzers, 8-inch artillery systems, and tank main-gun ammunition where high muzzle velocity and long barrel life are both required.

Applications
- 155 mm high-zone and maximum-zone propelling charges (M203, M119A2)
- BMCS M92 high-zone modular charges (up to 40 km range)
- 8-inch (203 mm) howitzer propelling charges
- Tank main-gun ammunition (105 mm and 120 mm)
- Large-calibre naval gun propellants
- Extended-range and rocket-assisted projectile (RAP) fire missions
Key Advantages
- High energy density — nitroguanidine provides significantly more energy per unit mass than single or double-base propellants
- Cool-burning — despite higher energy, flame temperature is kept lower than typical double-base propellants, extending gun-tube life
- Reduced flash and smoke — nitroguanidine content reduces muzzle flash signature
- Extended range — higher muzzle velocity enables long-range fire missions and RAP compatibility
- Wide temperature tolerance — stable ballistic performance across arctic to desert operating conditions
- Long shelf life — 15+ years in properly sealed storage
- M203 Red Bag Charge — uses M30A1 fill (maximum zone 8S)
- BMCS M92 — triple-base modular high-zone (40 km range)
- M1 Single-Base Propellant — low-to-mid zone counterpart
