Hydra 70
The M261 High-Explosive Multipurpose Submunition warhead provides improved lethality against light armor, wheeled vehicles, materiel, and personnel. The M261 is a cargo warhead consisting of a nose cone assembly, a warhead case, an integral fuze,
nine M73 submunitions, and an expulsion charge assembly. The primary warhead fuze, M439, is remotely set with the ARCS, MFD, or RMS to provide range settings (time of flight) from 500 meters to approximately 7,000 meters. On the AH-1, the RMS is programmable only from 700 meters to 6,900 meters.
Each submunition has a steel body that has a 3.2-ounce shaped charge of composition B for armor penetration.
Upon detonation, the shaped charge penetrates in line with its axis and the submunition body explodes into high velocity fragments (approximately 195 at 10 grains each up to 5,000 feet per second) to defeat soft targets.
Sixty-six percent of the time a submunition will land 5 degrees off center; 33 percent of the time a submunition will land 30 degrees off center.
Each M73 HE submunition has a shaped charge that can penetrate in excess of 4 inches of armor.
A submunition that lands 5 degrees off center has a 90-percent probability of producing casualties against prone, exposed personnel, within a 20-meter radius.
A submunition landing 30 degrees off center has a 90-percent probability of producing casualties within a 5 meter radius.
