Description
The 155mm, M804/M804A1 projectile is used in place of the M107 HE projectile for training in indirect fire of 155mm howitzers. The M804/M804A1 projectile contains a smoke canister In the fuze well, which provides for a visual determination of functioning. It can be used in training at less cost than an M107 projectile, without the blast and fragmentation which accompany functioning of an M107.
The M804/M804A1 is similar in weight and external configuration to the M107 HE projectile. The body of the projectile is a thick walled hollow steel shell, which contains no filler. A smoke canister, which has the same external appearance as a supplementary charge, is contained in the deep fuze cavity. A threaded lifting plug closes the fuze cavity at the nose of the projectile for handling and storage. A rotating band encircles the shell casing near the base and a steel base plate is welded over the base to prevent entry of propellant gases into the interior. The rotating band is protected during shipment and handling by a plastic grommet installed at the time of manufacture.
