# List of 40 mm grenades

This is a general collection of the world's many types of ammunition for grenade launchers in 40 mm (1.57 in) caliber.
Several countries have developed or adopted grenade launchers in 40 mm caliber.

## NATO

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). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers.

### 40×46 mm LV (40 mm low velocity)

40×46 mm LV (low velocity) is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, Heckler & Koch AG36 and M320 Grenade Launcher Module.
The propellant has low pressure and gives the projectile an average velocity of 78–84 m/s (256–276 ft/s) depending on the ammunition type.

#### 40 mm low-velocity ammunition types (Sweden)

Sweden currently operates the M203 grenade launcher (designated Granattillsats 40 mm Automatkarbin in Sweden) and thus uses the 40 mm low-velocity cartridge. Going against Swedish military tradition, the 40 mm low-velocity cartridge currently lacks a specified indigenous designation in Swedish service. Instead only the projectile types have designations.
Currently these projectile types can be found in Swedish service manuals.

#### SAGM fuze

The United States Army Armament Research, Development and Engineering Center (ARDEC) began development of a 40 mm smart airburst fuze (proximity fuze) in 2011 to improve the ability of grenade launchers like the M203 and M320 to engage targets in defilade. Called small arms grenade munitions (SAGMs), they double the lethality of the standard M433 grenade round by adding a small "smart" fuze sensor that detonates in the air to hit targets in cover or behind obstacles. The airburst function is similar to the XM25 CDTE, which has an onboard laser system to determine the distance to the target, but SAGMs are considered complementary to the XM25 rather than competing against it, as the XM25 provides low-angle fire while 40 mm launchers fire a lobbing trajectory. Integrated sensors and logic devices scan and filter the environment and then autonomously airburst the fuze without needing to be told to by the firer, thereby not requiring the soldier to carry extra weapon accessories. SAGMs enable soldiers to accurately incapacitate personnel targets in defilade at ranges between 50 and 500 meters. The round is engineered with three firing modes: airburst; point detonation; and self-destruct. A successful demonstration occurred in November 2013. Although the SAGM sensor does not need a laser rangefinder or any pre-fire programming sequence, it does require some skill by the user to aim and fire the round correctly so that it can detect the wall or obstruction to detonate in the air. The SAGM was to undergo evaluation in July 2015 and, if successful, transition into an official Army Program of Record by the end of the year. Not only does the fuze burst over walls, but it can detonate when passing cover like trees, bursting just as it senses and passes the trunk. The sort of sensor SAGMs use to differentiate clutter from triggering obstacles is highly classified, but shows airburst reliability of 76 percent.

### 40×51 mm MV (40 mm medium velocity)

40×51 mm MV (medium velocity), also known as 40×51 mm extended range low pressure (ERLP), is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers. Its purpose is to be an intermediate cartridge between the 40×46 mm low-velocity and 40×53 mm high-velocity cartridges and is thus referred to as 40 mm medium velocity.
The propellant has medium pressure and gives the projectile an average velocity of 100 m/s (328 ft/s) depending on the ammunition type. It has a maximum range of 800 meters, exceeding conventional extended range low-velocity variants by up to 375 meters.
The 40×51 mm MV cartridge was designed by Rheinmetall Denel Munitions for the US Special Operations Command (USSOCOM) after a 2008 requirement for enhanced range and lethality from hand-held 40 mm grenades. Rheinmetall answered by developing a new family of 40 mm grenades named 40 mm medium velocity and by 2019 the cartridge was undergoing NATO qualification.
Besides NATO the cartridge has been ordered by the South African National Defence Force (SANDF) as the cartridge for their next generation multiple grenade launcher, the Milkor Y4. SANDF approved acquisition in February 2018 but deliveries could not be finished until the end of 2020 due to the COVID-19 pandemic.

### 40×53 mm HV (40 mm high velocity)

40×53 mm HV (high velocity) is a NATO-standard high–low grenade launcher cartridge meant for mounted or crew-served automatic grenade launchers, such as the Mk.19 AGL, Mk 47 Striker, HK GMG, STK 40 AGL, and Daewoo K4.
The propellant has high pressure and gives the projectile an average velocity of 241 m/s (791 ft/s) depending on the ammunition type.

#### Green ammunition

The MK281 is a new type of 40 mm target practice grenade ammunition that has been accepted for use into the United States Marine Corps and the United States Army. It is "green" because it is non-toxic and non-dud producing (since it is a training round), meaning that there is no unexploded ordnance left to clean up on the range and heavy metals in the fuze do not leak into the ground. The MK281 was introduced into parts of the U.S. Armed Forces because of an executive order mandating that they buy green ammunition. The MK281 is manufactured by an American subsidiary of the Rheinmetall Group.
The United States Army has a requirement for a non-dud producing 40 mm training ammunition in both high- and low-velocity variants. The Army awarded four contracts to three United States companies to test designs. The resulting ammunition will not contain explosive energetics and have day and night visible, infrared, and thermal signatures.

### 40×47 mm (Poland)

40×47 mm is a cartridge caliber produced in Poland for their Pallad wz. 74 rifle-mounted grenade launchers (used with the AK family of rifles in the Polish Army, like the AKM/AKMS, Tantal and Beryl) and Pallad-D wz. 83 grenade launcher (standalone variant fitted with standard pistol grip and folding stock from the AKMS assault rifle). The construction is similar to the one used in 40×46 mm grenades, but they are not interchangeable.

### 40×47 mm (Romania)

40×47 mm is a cartridge caliber produced in Romania for their AG-40 model 77 and model 80 (today AG-40P) rifle-mounted grenade launchers. It features a casing with a high–low system. The propellant has low pressure and gives the projectile an average velocity of 78–120 m/s (256–394 ft/s) depending on the ammunition type.
Production was originally handled by the arms factory Uzina Mecanica Filiasi, however production was later moved to the arms factory Uzina Mecanica Tohan Zărnești, today more commonly known as S. Tohan S.A., a subsidiary of ROMARM.
Several types of the Romanian 40×47 mm exist:
* High explosive
* High-explosive fragmentation
* Smoke
* Incendiary
* Tear gas
* Practice, featuring a small flash charge and smoke signal.
* Inert
Tohan currently (2021) offers a 40×47 mm high explosive type called GETZ (Grenadă Explozivă Tohan Zărnești) and an inert version called GITZ (Grenadă Inertă Tohan Zărnești). Both cartridges are 105 mm (4.13 in) long, with GETZ weighing 0.260 kg (0.573 lb) and GITZ 0.200 kg (0.441 lb).

### 40×74.5 mm (Romania)

40×74.5 mm is a cartridge caliber produced in Romania for their AGA-40 Model 85 automatic grenade launcher. It features a casing with a high–low system. The propellant has high pressure and gives the projectile an average velocity of 216–223 m/s (709–732 ft/s) depending on the ammunition type.
Production is handled by the arms factory Uzina Mecanica Plopeni, a subsidiary of ROMARM.
Three ammunition types are known:
* A high-explosive grenade producing 150 fragments weighing 0.2 g (0.0071 oz) each, creating a deadly radius of 10 meters (33 feet) upon impact.
* A high-explosive dual-purpose grenade capable of penetrating 50 mm (2.0 in) of steel armor.
* An inert cartridge for loading exercise.

### 40×56mm (Japan)

The standard adopted by the Japan Ground Self-Defense Force in its Type 96 grenade launcher. It is manufactured by Daikin Industries and the '40 mm anti-personnel light armour-piercing round' (ammunition length 112 mm, weight 371 g) is a multi-purpose grenade with a moulded explosive charge. There is also a '40 mm training round' available.

## Caseless ammunition
### 40 mm VOG-25 (Russia)

40 mm VOG-25 (Russian Cyrillic: ВОГ-25) (GRAU-Index: 7P17 (Russian Cyrillic: 7П17)) is a unique type of 40 mm grenade designed in the Soviet Union for hand-held grenade launchers, such as the Soviet GP-25 Kostyor and GP-30 Obuvka. Instead of a casing, the VOG-25 is caseless ammunition, featuring its propellant in an expansion chamber at the base of the projectile, functioning more like a mortar round than conventional cased ammunition.
Today it is used primarily by the Russian Armed Forces in weapons such as the GP-34, BG-15 Mukha and RG-6. Several types exist but the most common version is the default VOG-25 high-explosive version.
The VOG-25 is 103 mm (4.1 in) long, weighs 250 g (8.8 oz), and features a 48 g (1.7 oz) explosive charge. It has a muzzle velocity of 76 m/s (250 ft/s) and will self-destruct after 14 seconds.

### 40 mm Metal Storm (Australia)

During its time (1994–2012), Metal Storm Limited in Australia designed several automatic caseless 40 mm grenade launcher systems based on their own caseless ammunition weapon design. Unlike common caseless ammunition and their weapon systems the Metal Storm design lacked a feeding magazine and instead stacked the projectiles in front of each other in the barrel with the propellant in between the projectiles. The system lacked moving parts and the propellant was electronically fired. The 40 mm grenades used in the systems were off the shelf existing warheads converted to function in the design.
