SADARM

The original platform for the submunition was the 203 mm M509 Improved Conventional Munition (ICM) projectile, and the concept was demonstrated in the late 1970s.

By 1983 the project shifted focus to 155 mm caliber and the target set was changed to self-propelled howitzers and other lightly armored vehicles.

With the target threat (howitzers) removed from probable conflict areas due to the collapse of the Soviet Union the SADARM program was terminated prior to full-rate production.

When the submunition detects a target, its 1.5 kg LX-14 explosive charge is detonated to project an explosively formed penetrator that has enough energy to penetrate the thin top armor of most main battle tanks up to a range of around 152 m. If the submunition reaches the ground before it finds a target it self-destructs.

The system was used for the first time during combat during the 2003 Invasion of Iraq,[2][3] with a total of 121 rounds reported fired by the 3rd Infantry Division with 48 vehicle kills attributed to 108 M898 SADARM projectiles.
