\ 155 MM M3A1
The M3 series propelling charges are green bag type designed for use in 155 mm howitzers for firing in Zones 1 through 5. The full charge consists of approximately 5.50 pounds of propellant including a base charge and four unequal increments s loaded in cloth bags. The hags are fastened together with four cloth straps sewn to the base and tied on top of Increment 5. Charge M3 is assembled. without flash reducer pads. Charge M3A1 includes 3 flash reducer pads containing potassium nitrate or potassium sulfate. An ounce pad is assembled forward of the base charge and there are two 1-ounce pads forward of Increments 4 and 5. The igniter charge of the M3A1 is 3.5 ounces of clean-burning igniter (CBI) in a red cloth bag sewn to the rear of the base section. The igniter charge of the M3 is 3 ounces of black powder.

\ 155 MM M4A2
The M4A2 (white bag) Propelling Charge is a separate loading charge used in 155mm howitzers for firing in Zones 3, 4, 5, 6, and 7. The full M4A2 Propelling Charge consists of 13.4 lbs (6 kg), of M1 propellant and is divided between a base charge and four unequal increments loaded in white cloth bags. The increments are connected by four cloth tapes sewn to the base and tied on top of the increment. The igniter contains a clean-burning igniter (CBI) in a red cloth pad sewn to the bottom of the base charge. A flash reducer pad containing potassium sulfate or potassium nitrate is installed at the front end of the base pad (Increment 3). The seams in the base pad are inverted so that the edges of the cloth are inward to reduce residue after firing.

\ 155 MM M119A2
The M4A2 (white bag) Propelling Charge is a separate loading charge used in 155mm howitzers for firing in Zones 3, 4, 5, 6, and 7. The M119A2 Propelling Charge is a single increment red bag charge which contains a base igniter pad with 4 ounces CBI powder and a centre spot of 0.5 ounces of black powder. The charge is approximately 29 inches long by 6 inches in diameter and contains 20,9 pounds of M6 propellant. The forward end of the charge has a 3 ounces lead foil liner and four pockets sewn longitudinally to the circumference. Each of the four pockets contains 4 ounces of potassium sulfate to act as a flash reducer.

\ BI-MODULAR CHARGE SYSTEM (BMCS) FOR 155 MM CANNON HOWITZER
BMCS is a further developmental stage of the design of charge systems for separated ammunition. These are the 2nd generation modular charges. The complete Bi-Modular Charge System (BMCS) represents in its design substance the solution of charge systems by two types of modules: A bottom Charge module – BC-E and a top Charge module – TCF. The BC-E module serves for covering small ranges of fire (it consists of one Zone-1 module and two Zone-2 modules). Type of TC-F module serves for covering of long and maximum ranges of fire (it comprises of three to six modules – Zone – 3, 4, 5, and 6). BMCS is advantageous over conventional cloth bag charges because of simpler operation and reduced logistics during storage, transportation, and war scenario.
\ MEDIUM CALIBRE SINGLE BASE PROPELLANT
We develop and manufacture high-performance single-base propellants for medium calibre ammunition with a long tradition of innovation, performance, security of supply, and customer satisfaction. Our propellant manufacturing plant at Granada (Spain), founded in 1897, holds our Center of Excellence for Propellants, which designs and develops improved extruded and coated technologies for the most demanding applications. A wide the customer base of MCA manufacturers across NATO and allied countries use our propellants, manufactured according to their requirements or following co-development with our Center of Excellence.
