Today, the National Guard celebrates its 389th birthday! Join us in saying Happy Birthday.
On this date in 1636, the first militia regiments in North America organized in Massachusetts, forming the foundation of what would become the Massachusetts Army National Guard.
On this day in US military history.....15 Dec. 1960: the XM79, after being given a new sight, was dubbed the M79.
The M79 grenade launcher was produced in the US between 1961 and 1971, during which time 350,000 were built. It had a simple design comprised of five parts: the receiver group; the fore-end assembly, which bed the barrel to the receiver; the barrel group; the sight assembly; and the stock, made from either wood or fiberglass. It was 73.1 CM long, with the barrel measuring 36.83 CM. It had two sights. The front was a fixed blade, while the rear could fold and be adjusted for ranges between 75 and 375 meters. The M79 grenade launcher had a “high-low” propulsion system that greatly reduced recoil and increased its range. It was most effective when fired from around 350 meters and had a maximum range of 400 meters.
The M79 grenade launcher could fire a host of rounds, including anti-personnel, buckshot, illumination, flechette, and smoke. Among the most effective was the M406 40 mm HE grenade, which fired at a velocity of 75 meters per second. While it didn’t have enough energy to kill a target, it could penetrate the abdomen and cause a hematoma.
Two rounds were specifically developed for the launcher. The first was the flechette, which fired 45 10-grain steel flechettes at a target. It proved to be ineffective, as it would hit sideways – not point-first – and simply bounce off. The second was the M576 buckshot, which contained 24-grain metal pellets and was incredibly lethal at close range. However, it drastically lost its effectiveness the farther the grenadier was from its target. The rounds needed to travel 40 meters to arm.
the M79 was replaced by both the XM148 and the M203, which were under-barrel grenade launchers. While the XM148 was discontinued due to issues that plagued its design, the M203 was a success and became standardized.
