The United States Armed Forces has created a plethora of different types of 40 mm grenades in both the low-velocity 40×46 mm and high-velocity 40×53 mm calibers which uses what it calls a high-low propulsion system which keeps recoil forces within the boundaries of an infantry weapon. Presented on this page is a basic overview.

40mm高速榴弹主要用于 美军的M75/M129、Mk19 等自动榴弹发射器，而德国的 GMG 、新加波的 CIS40-AGL 等多个国家的自动榴弹发射器也是采用这种口径。 40mm高速榴弹一般用 M16A2 式金属弹链供弹，通常50发一链。 M384 HE（左）和M430 HEDP（右）的结构，可以看出弹壳内的高低压室与40×46mm低速弹的不同. 40mm的高速榴弹与低速榴弹在外形上很相近，只是高速榴弹的弹壳长一些，但全弹长却不一定是高速榴弹长，因为有些低速榴弹的弹头更长. 40×53mm榴弹 …

Several countries have developed or adopted grenade launchers in 40 mm caliber. [1] NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV).

Modern training cartridge with highly visible impact signature, designed to provide realistic training exercises during daytime without risk of generating unexploded ordnance and range fires. Suitable for use in Mk19 Mod 3, H&K GMG and other Automatic Grenade Launchers. It may be offered linked with the TP-DM-T version, in different configurations.

Dual Purpose HV grenades for use on Automatic Grenade Launchers (AGL) against a variety of targets (light armor, materiel or dismounted infantry). Available with standard PD or self-destruct fuzes. Qualified for use in grenade launcher Mk19 and LAG 40. Tested in Mk47 and H&K grenade launcher. HEDP round homologated by Spanish MoD.

40x53mm types include the M383 (and the M383E1) and the M384. HE grenades have been considered the standard for both types of 40 mm grenades, but over the years the functions of the weapons using these grenades has dramatically expanded, and as a result the need to be able to engage larger and more armored targets.

Effective against light armoured and personnel targets, and performs well on oblique angle targets. A High Explosive Self-Destruct round that expels fragments along with the blast, rendering it effective for use against personnel targets.

2017年11月15日 · The company’s answer is to develop 40x53mm high-velocity grenades using programmable components that allow soldiers to lase the distance to an enemy UAV, transmit that data into the grenade, which then programs that grenade to airburst at that particular altitude.

40x53mm High Explosive Fragmentation Grenade with Self- Destruction is intended to defeat enemy troops in open terrain at distance up to 2 200m. The grenade is fitted with distance-armed, self-destruct fuze. Self-Destruct grenades have a huge advantage as they will explode within 22-26 seconds even if they have not exploded by the main fuze.

40x53 mm Round RHV- HEDP with High Explosive Dual Purpose Grenade GHV- HEDP. NSN:1310-50-001-7527. The 40x53 mm Round RHV-HEDP is intended to destroy enemy manpower, transport means and light-armoured objects at distance of up to 2200 m.
