The Advanced Power Technology division of Folsom Technologies International is an innovative and service oriented company providing specialist solutions to the defense industry. Our engineering staff have many years of extensive experience, both at APTI and in the international community, in the design, development and testing of weapon systems ranging from 20mm rapid fire rotary cannons and ammunition handling systems to 203mm howitzers. This includes both towed and self-propelled weapons and all their associated subsystems including complete vehicle and turret designs, recoil energy recovery, traversing, elevation, equilibration, loading and handling mechanisms as well as the design of the ammunition. Energy recovery systems, which harness some of the recoil energy to power selected hydraulic devices, have been successfully designed and employed on both 155mm and 203mm weapons. We have proven success in turning ideas into reality.
