Mk19 (Mark 19) automatic grenade launcher / grenade machine gun (USA)

The very early (probably prototype) Mark 19 model 0 grenade launcher; note that it lacks sights and any grips.

The Mk.19 mod.1 was the first upgrade of the basic design; about 1000 of such guns were converted from Mod.0 or or built as new

Experimental Mk.19 mod.2 grenade launcher in remotely-controlled from, with electric trigger. Note that it had much slimmer profile - too bad it never worked well

Development of the Mark 19 (Mk.19 in short) grenade machine gun was initiated by US Navy in 1966, after the initial experience gained during Vietnam war. Since about 1962, US forces in Vietnam used several multi-shot 40mm grenade launchers that fired low velocity 40x46mm M406 grenades originally developed for M79 single-shot weapon. Among these, most notable was the Mark 18 belt-fed grenade launcher, developed by Hughes corporation; this was a hand-cranked weapon that provided significant short-range firepower to riverine crafts and marine infantry. However, all such weapons lacked effective range, and US Navy decided to develop a new, automatic, self-powered weapon around the high-velocity 40x53mm M384 grenade (which was originally developed for US Army's M75 automatic grenade launcher, used on UH-1 and AH-1 combat helicopters). Development of Mark 19 automatic grenade launcher began in July 1966, and by October 1967 firs three working prototypes of the new weapon were ready for official field trials. The production Mark 19 Model 0 grenade launchers entered service in Vietnam in early 1968, on board of riverine crafts and UH-1 Huey gunship helicopters belonging to US Navy. In around 1971, the basic design was slightly improved, and type classified as Mark 19 Model 1; these weapons were manufactured by US Naval Ordnance Station Louisville. In around 1974, US Navy attempted to produce more streamlined version of the basic design, known as Mk.19 Mod.2, but this development never went past prototype stage, and in 1976 work began on simplified and more robust improved version of the Mk.19, which was type classified as Mark 19 Model 3 (Mk.19 mod.3) in 1981. The manufacturing contract for Mk.19 Mod.3 weapons was granted to Saco Defence (now General Dynamics Armament and Technical Products - GDATP). By the year 2000, at least 25 thousands of Mk.19 mod.3 grenade launchers were in service worldwide, mostly with all branches of US armed forces.

The Mark 19 Model 3 (Mk.19 mod.3) automatic grenade launcher is air cooled, belt fed, blowback operated machine gun. It fires from open bolt and uses advanced primer ignition principle to decrease peak recoil. To provide minimum of parts and maximum reliability of feeding, Mk.19 uses two-stage feed, when each round is first withdrawn rearwards from the belt on the opening stroke of the belt and then placed into T-slot cut in the bolt face; on the closing stroke, the round is already properly positioned on the bolt and is feed straight to the chamber; empty cartridge cases are ejected to the bottom as they are pushed down from the T-slot by the next cartridge (the same principle has been employed on some WW1 era machine guns). Ammunition is fed using special disintegrating belt; when rounds are fed into the chamber, links stay on the case and are ejected from the gun along with spent cartridge cases. Ammunition is usually supplied in belt boxes with capacity of 32 or 48 rounds. Loaded 32-round box weights about 19 kg (42 lbs). Mk.19 grenade launcher is fitted with dual spade grips, and can be fired in semi-automatic of full automatic modes. Alternatively, electric trigger pack can be installed for remote controlled mounts. It can be installed on standard M3 tripods (using Mark 64 cradle / adapter) for infantry use, or on various vehicle mounts on jeeps, armored vehicles, naval vessels etc. By default, Mk.19 mod.3 grenade launchers are equipped with machinegun type iron sights, but other types of sighting equipment (including night sights and range-finding electronic sights) are available. Today the primary ammunition type for Mk.19 mod.3 in US service is the 40mm M430 High Explosive, Dual Purpose (HEDP) round, which can penetrate up to 50mm (2") of rolled homogenous armor and provide effective anti-personnel fragmentation effect with damage radius of about 15 meters (lethal damage / kill zone radius 5 meters).

Rate of fire: 225-300 rounds per minute

The development of the more lightweight and effective weapon which could replace venerable Mk.19 Mod.3 automatic grenade launcher in US and foreign service, has been initiated by Saco Defense Company (now General Dynamics Armament and Technical Products - GDATP) during late 1980s.First prototypes of the new weapon appeared by mid-1990s, and in 1995 US DoD approved the industry team which then consisted of Saco Defense (now GDATP) as a weapon producer and system integrator, and Raytheon as a provider of advanced electronic sighting and fire control equipment. Later on, team was joined by Norwegian NAMMO Oy company, which develops the advanced, air- bursting 40mm ammunition for new weapon. In the year of 2003, US Special Operation Command (USSOCOM) adopted the GDATP Striker 40 40mm automatic grenade launcher as Mark 47 model 0, complete with its new tripod mount and AN/PVG-1 Lightweight Video Sight developed by Raytheon. These weapons now (February 2006) are in limited service with US Special Operation forces in Afghanistan and Iraq, and also are being considered for adoption by US Marine Corps. Mk.47 grenade launchers are compatible with full spectrum on NATO-standard 40mm high velocity ammunition; advanced air-bursting ammunition with programmable fuses is being developed for this weapon. Once this ammunition will be available, the Mk.47 / Striker 40 weapon system will provide serious and more cost-effective alternative to the much-discussed 25mm XM307 ACSW weapons now in development.

Mark 47 Model 0 (mk.47 mod.0) automatic grenade launcher is short recoil operated, locked breech weapon that fires from closed bolt for improved first-shot hit probability. Weapon is air-cooled and belt fed, using standard disintegrating belts, same as Mk.19 Mod.3 launcher. Standard belts are supplied in 32 or 48 round boxes. Weapon is equipped with newly developed Mk.108 mod.0 tripod with T&E mechanisms and brake that allows to lock weapon on pre-selected target spot. The key member of the Striker 40 system is the AN/PVG-1 Lightweight Video Sight (LVS), which offers 3X magnification TV view on target, combined with laser range finder and ballistic computer; sight also has interface connectors that allow to link it to optional thermal night sighting equipment which can be installed on the weapon; once the night sight is connected, operator can select TV or thermal picture via the single button. The LVS allows to accurately measure the range to the target then aim the gun accurately for high first shot hit accuracy. LVS is installed on the right side of the weapon, and is controlled by the buttons and four-position "joystick" located at the rear of the receiver, between and above spade grips.

Type	Single Action multi-barrel
Caliber(s)	7.62mm underwater
Weight unloaded	about 1200 g
Length	200 mm
Barrel length	n/a
Magazine capacity	5 rounds in disposable barrel cluster

The HK P11 is one of the least known weapons to emerge from the Heckler & Koch factory. Developed during the early 1970s to arm frogmen (combat divers), this weapon is apparently in use with the Navies of Germany, Italy, France, Norway, the UK and the USA. This highly unusual weapon is probably the only serious rival to the Soviet underwater pistol, which appeared in late 1960s. The P11 and its ammunition is somewhat bulkier than its Soviet counterparts (the SPP-1M), but, on the other hand, the P11 has one round more capacity and a larger caliber, probably resulting in better lethality.

The HK P11 pistol is mainly unusual in the fact that it is not self-loading. Instead, it uses a quick-detachable cluster of five barrels, each factory-loaded with a powder charge and long, needle-like, drag-stabilized projectile. The pistol is reloaded by the replacement of an entire barrel cluster. In combat, the empty clusters are discarded, in training these are collected and later sent back to factory for reloading. Loaded barrels are protected from salt water by thin diaphragms, which are destroyed by the fired bullet at the instant of firing. Powder charges in each barrel are ignited using electricity, provided by two 9-Volt batteries, stored in a sealed container in the grip of the pistol. The effective range underwater depends on the depth, and is about 15 metres near to the surface. Above the water, the effective range is quoted as being around 30 metres, and while long and relatively heavy bullets can be lethal at longer ranges, the chances of hitting any target beyond the given range is minimal. This is because the barrels are not rifled, and bullets are not stabilized in the air, thus tumbling and yawing in flight through the air.

Steyr GB (Austria)

Steyr GB


Steyr GB - cut-out drawing

Type: Double Action
Chamber: 9x19mm Luger/Parabellum
Weight: 845 g empty; 1285 g loaed
Length: 216 mm
Barrel length: 136 mm
Capacity: 18 rounds

The development of the GB pistol was started by Steyr-Daimler-Puch AG (now Steyr-Mannliher AG), Austria, in the early 1970s, when the Austrian army announced its plans to replace aging P38s and High Powers with the new pistol. Original design, labelled as PI-18, was developed in 1974, and final version, called GB, entered production in 1981. The production of the GB was ceased circa 1988, after some 15.000 to 20.000 pistols had been produced.

The GB is a blowback-operated, gas-retarded blowback semi auto pistol. It uses some of the hot powder gases, feed from the barrel into the front part of the slide, to slow down the retraction of the slide before the bullet leave the barrel. This scheme was developed by German engineer Barnitzke at the end of the WW2. The gas brake is formed by the barrel, its bushing and the slide.
The trigger of the GB is of double action design, with the slide mounted decocker lever. GB also featured firing pin block that unlocks the firing pin only when the trigger is completely depressed.
The frame and the slide is made from carbon steel with special high-strenght finish. Barrel has polygonal rifling and is chrome lined, and solidly attached to the frame.
The sights are fixed and featured white-dot inserts (one in the front sight blade and two - around the rear sights notch).
Some early GBs were manufactured with steel grip panels, with all the rest manufactured with plastic checkered grips.

Thanks to its gas-retarded blowback design and solid weight, that resulted in low felt recoil, and to the barrel with polygonal rifling, that toesn't move when firing, the Steyr GB displayed wery good accuracy. The reliability is also adequate, at least. While the GB failed at the Austrian and USA Army pistol trials (won respectively by Glock 17 and Beretta 92FS-B), it was used by some Law Enforcement and Special Operations forces, and also was sold to civilians in Europe and USA.

The Device "D" (Изделие Д in Russian nomenclature) noiseless grenade launcher / handgun is an unique weapon, which was developed during 1960s or early 1970s for Soviet Spetsnaz forces. One of the main goals of the Spetsnaz at the time (in the case of the outbreak of the 'hot' war in Europe) was to attack and disable / destroy key NATO facilities such as C&C posts, ammunition and fuel storage depots, radar facilities, parked tactical aircrafts, and most important, tactical / medium range ballistic missile launchers. All these targets were relatively 'soft-skinned', so it was estimated that a 30mm projectile could carry enough explosives to penetrate the skin of the vehicle or equipment container and cause enough damage to disable it (i.e. ignite the fuel in the storage tank or make Pershing ballistic missile or fighter-bomber aircraft inoperable). To provide the Spetsnaz operators with maximum stealth, it was decided to make noiseless / flash-less launcher for such projectile, as this would help to hide actual firing position and thus improve chances of getaway. To provide more flexibility for the operators, it was decided to make the weapon dual purpose - it can fire 30mm explosive or incendiary grenades against material targets (aircrafts, fuel tanks, missiles etc) at ranges of up to 300 meters, or 9mm AP bullets against enemy personnel at ranges of up to 200 meters. Designated Device "D" (Изделие Д), this weapon was issued to certain units of Soviet Spetsnaz since ninety seventies, and apparently is still in limited use by elite Russian military Spetsnaz and FSB (former KGB) anti-terrorist units.

The heart of the Device "D" (Изделие Д) weapon complex is the 9mm (9x93) noiseless cartridge, designed along the lines of the smaller 7.62mm (7.62x63) PZ "Zmeya" cartridge. The heavy steel cartridge case holds small powder charge and a piston, which can move inside the case to violently push the projectile out of the case and then jam itself at the case mouth, capturing powder gases (prime source f the gun shot sound and flash) inside the case. There are two types of cartridges intended for use in Device D - the 9mm PFAM "Falanga" cartridge, loaded with AP bullet, and 9mm PMAM "Mundshtuck" cartridge, loaded with pusher rod which transfers the energy of the piston to the separately loaded grenade. The "Falanga" bullet is made of hardened steel with brass driving band at the front. The bullet weight is about 28 gram (432 grains) and the muzzle velocity is about 250 m/s (820 fps). According to available information, PFAM bullet can penetrate 5mm of mild steel at 100 meters. The 30mm grenade, which is used along with 9mm PMAM cartridge, is designated BMYa-31 "Yascheritsa" (Lizard). This projectile is loaded with unspecified amount of explosive or incendiary composition, and can penetrate up to 10mm of steel and then ignite fuel stored inside. BMYa-31 grenade weights about 130 gram (~4.5 oz) and PMAM cartridge propels it out of the muzzle cup launcher with muzzle velocity of about 110 m/s (360 fps). BMYa-31 projectile features pre-engraved rifling and a pusher rod at the rear, which comes into the contact with the piston of the propelling cartridge when gun is fully loaded. Inert grenade projectiles also are available for live fire practice.
The Device D itself is a large, single-shot, bolt action pistol. It is loaded with single cartridge through the opening at the top when bolt is retracted. Once cartridge is placed in the gun, the bolt is pushed forward and then rotated to lock. To provide necessary accuracy when firing a heavy weapon, it can be fitted with detachable shoulder stock / holster and a detachable adjustable bipod. To launch grenades, gun must be fitted with detachable muzzle cup launcher and an additional grenade sight, which is attached to the left side of the gun. Launcher PMAM cartridges are loaded same way as bullet-firing PFAM cartridges, and grenades are loaded into the muzzle cup from the front until locked inside by the spring retainer. Cup launcher is equipped with special manual extractor necessary for unloading of unfired grenades.

The development of a large-caliber heavy machine gun in USA was initiated in 1918, at the direct request of General Pershing, the commander of the US expeditionary corps in Europe. He requested a heavy gun capable of destroying military aircraft and ground targets such as tanks and armored cars. The task of developing such a gun and ammunition was passed to John Browning (then based at Colt’s factory) and the Winchester Arms Co. respectively. The basic pattern of the new heavy machine gun was sealed in 1921. Officially adopted in 1923 as “machine gun, .50 calibre, M1921”, this water cooled, belt fed gun became the prime AA weapon for the infantry and the navy.
In the year 1930 US Army adopted a slightly modified .50 caliber M1921A1 machine gun, and further work on this gun concentrated on the development of a universal weapon suitable for most roles. The key design changes were made by Dr. Samuel G. Green, who redesigned the basic receiver so it could be used in conjunction with either water-cooled or air-cooled barrels, encased in a water jacket or short perforated sleeve respectively. He also developed a switchable left or right side belt-feeding unit. The US Army adopted the new, improved fifty-caliber machine gun as the M2, in a water-cooled anti-aircraft version, an air-cooled ground mount version and as an aircraft weapon. Since the original air-cooled barrels were too light to provide any degree of sustained fire in ground applications, heavier barrels were soon introduced for the ground-mounted guns, so this weapon became the “M2 Heavy Barrel” or M2HB for short. In 1938 the barrel of the M2HB was lengthened to provide more striking energy and longer range, and in this form the M2HB was made in great numbers during the Second World War. US arms factories turned out a little less than 2 million M2 guns in all versions between 1941 and 1945, of which over 400,000 were made in M2HB configuration for ground use.
After the WW2, .50-caliber Browning guns found a wide acceptance across the world, and today are still widely used as ground and vehicle guns in most of NATO countries and many others. Production of new M2HB guns is continued in USA and Belgium.

Browning M2HB machine gun is belt-fed, air-cooled machine weapon capable of semi-automatic and automatic fire. The M2HB fires from a closed bolt at all times, and uses a short-recoil operated action with a vertically sliding locking block, which rises up to lock the bolt to the barrel extension, and drops down on recoil to unlock the bolt from the barrel. It also has a bolt accelerator, made in the form of a lever located at the bottom of the receiver. Upon recoil, once the barrel is unlocked from the bolt, it strikes the accelerator, so the kinetic energy of the recoiling barrel is quickly transmitted to the bolt, improving the reliability of the weapon. Barrels are screwed into the barrel extension and are not quick-detachable on standard M2HB weapons; furthermore, once the barrel is installed in the weapon, the headspace must be adjusted prior to firing, or the weapon may fail to fire or produce a serious jam. However, quick change barrel (QCB) kits were developed by several companies during the 1970s and 1980s, and every M2HB weapon can be converted to a QCB version with the replacement of only a few parts, including the barrel. The rear part of the barrel is enclosed in a short, tubular, barrel jacket with cooling slots. The back of the receiver houses a bolt buffer, and additional buffer is used to soften the movement of the heavy barrel. On infantry guns, the cocking handle was invariably installed on the right side of the weapon, but slots were made on both sides of the receiver for tank installations which may require a left-side cocking handle.
Browning M2HB machine guns use a disintegrating steel belt, with the feed switchable from one side to the other through the re-installation of certain parts in the feed unit. The belt feed is of the two stage type – every cartridge is first withdrawn from the belt toward the rear by the pivoting extractor lever, attached to the bolt. Once the cartridge is clear of the belt, it is lowered into a T-slot cut into the bolt face, and pushed forward into the barrel. Spent cartridge cases are forced down the T-slot and out of the weapon through an opening at the bottom of the receiver by the following cartridges, or by the pivoting belt extractor lever (for the last cartridge case). A rotary switch is used to select the track for left or right side feed.
Since the gun fires from a closed bolt, it has a separate firing pin, powered by its own spring, and hosted inside the bolt along with the sear and cocking lever. Upon the recoil stroke of the bolt, the cocking lever pulls the firing pin back until it is engaged by the sear. Once the bolt is fully in battery (locked closed), a pull on the trigger raises the trigger bar so it acts on the sear and releases the firing pin. The standard firing controls consist of a push-type thumb trigger and sear release buttons located between the dual spade grips. Alternatively, an electric solenoid trigger can be installed for mounted vehicle applications. The M2HB has an unusual method of providing semi-automatic fire (probably added to the basic design as an afterthought) – it has a bolt latch, which locks the bolt to the bolt buffer in the open position after each shot. Therefore, if gun is fired in semi-automatic mode (single shots), for each shot the operator must first release the bolt forward by pressing the bolt latch release, located next to the thumb trigger (as the gun fires from a closed bolt). After the bolt is released and the gun is loaded, the operator may push the trigger to fire a single bullet. If the automatic mode is desired, the bolt latch must be turned off and locked by turning its lock to the left. In this position it will not engage the bolt and the gun will fire continuously as long as the trigger is pressed. It must be noted that original M2HB guns had no manual safeties; however, the recent M2E2 upgrade, developed by General Dynamics, includes, among other items, an additional manual safety located next to the trigger.
Standard sights consist of a folding blade front and frame-type rear. The rear sight is mounted on the receiver, the front sight is located at the front of the receiver and protected by an arc-shaped sight protector. Additionally, various types of telescopic and night sights can be installed using appropriate mountings.
