Figure 2-42. 8-inch HE and HERA projectiles.
The M650 is an 8-inch HERA projectile with an extended-range capability. (Refer to Figure 2-42.) It is intended
for use against targets at ranges beyond those currently attainable with M106 projectiles. The M650 projectile
consists of three major components. These are the aluminum ogive, the steel warhead, and the steel-alloy rocket
motor section. It is fitted with a lifting plug at the nose for handling. Its color code is an olive-drab body with
yellow markings. The DODIC for the M650 is D624.
Antipersonnel projectiles are designed to deliver a concentration of antipersonnel grenades on a designated
target. Examples of 8-inch antipersonnel projectiles are shown in Figure 2-43.
The M404 is an 8-inch, HE, base-ejection-type projectile that is designed to deliver 104 M43 antipersonnel
grenades. It has a forged-steel body with a streamlined ogive, a threaded base plug, and an eyebolt lifting plug.
At a predetermined time in flight, the fuze functions, expelling the grenades. Upon ground impact, submunitions
are ejected 4 to 6 feet above the ground, where they detonate. The color code for the M404 is an olive-drab body
with yellow diamonds and markings. Its DODIC is D684.
M509-series munitions are 8-inch, HE, base-ejection-type projectiles designed to deliver 180 M42
antipersonnel/anti-material grenades. They have a forged-steel body with an aluminum-alloy ogive and base
plug. They use a universal fusible lifting plug for handling. At a predetermined time in flight, the fuze functions,
expelling the grenades. Upon ground or target impact, the submunitions detonate. Another effect available with
M509-series projectiles is achieved by replacing the original expelling charge with a spotting charge designed to
detonate the entire projectile as if it were a bulk-loaded HE projectile. The color code for M509-series munitions
is an olive-drab body with yellow diamonds and markings. Their DODIC is D651.
