Extended Range As a leader in development and production of solid propellant systems for extended range artillery ammunition, Nammo Talley's history is solid. We have manufactured over 2,500,000 pounds of modern HTPB composite propellants for the U.S. Army's most modern extended range artillery systems We have designed propellant and inhibitor systems to survive high G, high spin, and gun tube environments We have development and production expertise demonstrated in both non-propulsive, drag reduction (base burner/base bleed) systems, and rocket-assisted systems for 155mm and 105mm artillery systems Nammo Talley engineers, chemists, and technicians have proven track records in developing and tailoring propellant systems to meet program needs
