Abstract: The invention relates to a cartridge (14) which can be used in an anti-tank rocket launcher (10), comprising launching tubes (16) open at both ends, wherein a projectile (18) and a propelling charge cartridge (20) are arranged. To ignite the propelling charge, a non-electric igniting line (56) which is joined to the propelling charge cartridge (20) is used, said line exiting from the launching tube (16) at one end thereof The invention avoids direct ignition of the propelling charge, from an outer radial direction and dispenses with the use of the radial openings therefor in the launching tube (16). The launching tube can also be made from non-metal and mechanically weaker material, thereby considerably reducing the total weight of the cartridge (14) in a considerable manner.
