40x46mm NATO Low-Velocity

Notes: First designed just before the US involvement in Vietnam, the 40x46mm grenade (known as the 40mm LV or 40mm NATO LV round after the adoption of the 40x53mm High-Velocity grenade designed for use in automatic grenade launchers) was a result of Project Niblick, and was adopted in late 1960 for use with the M-79 grenade launcher. The 40x46mm round had an interesting “high-low” firing system – the initial propelling charge used high pressure, which bled into a low-pressure chamber that actually propelled the grenade and lessened the felt recoil. Later, the XM-148 and M-203 grenade launchers were designed to fit under a rifle barrel, and the 40x46mm round has proliferated ever since, as have the different types of rounds available.

Virtually all 40x46 rounds are low-velocity rounds, having an average muzzle velocity of merely 76 meters per second. Recently, as a result of experience in Afghanistan and Iraq, new, longer rounds have become available, with improvements from range and explosive power to innovative designs that employ a parachute-lowered camera to check out a concealed enemy position. Most of these improved rounds are longer than 46mm (most are 51mm long), are actually medium-velocity rounds instead of low-velocity rounds, and will not fit into underbarrel grenade launchers that slide forward to open.

Categories below are largely generic, instead of referring to the specific round made by one company or another.
