The Heckler & Koch underwater pistol was developed during the 1970’s to arm the Kampfshwimmer, the German commando frogmen unit of Germany’s armed forces.

Underwater Pistols Used By Combat Divers Around The World

The Soviet Union was the first to begin developing firearms specifically for their combat divers. The Soviet Navy was worried about divers attacking their ships in their naval anchorages, and in particular those of the Black Sea fleet based in Sevastopol, located on the Crimean Peninsula, and Odessa, Ukraine. These anchorages could be easily threatened by NATO forces operating out of Turkey. It wasn’t an idle worry. The use of divers to attack anchored ships was used extensively by the Italian Navy during World War II, and the British Navy developed their techniques by using captured Italian equipment.

The Soviet Navy had as many as 1,000 combat divers in their Black Sea fleet,
but averaged about 300 in most other naval bases. Known as Naval Spetnaz
divers, these divers were not trained to the same level as US Navy SEALs, but then again, they had a more limited role in protecting their fleet from underwater attacks than US teams.

The B-V1-307 Underwater Handgun

The designer of the first underwater pistol was Dmitry Shiryaev of the TsNIITochMash plant, otherwise known as the Central Research Institute for precision machine building, a Russian industrial-design bureau. In the early 1960s, he designed the B-VI-307, a simple four-barrelled hinged-break pistol that fired a flechette, or tiny arrow, rocket-assisted 7.62mm round. These rounds stabilized in water by using a cavitation bubble. This bubble was generated around the front of the flechette by the specially designed shape of the nose. When fired above water, however, the round was for all intents and purposes useless. The flechette tumbled once it left the barrel and was only capable of causing a wound at point-blank range.

The Soviet Union’s B-VI 307 underwater pistol was a simple four-barrelled hinged-break pistol that fired a flechette rocket-assisted 7.62mm round.



The gun had one round in each chamber, with an opening on each of the bolt faces for the striker. The double-action trigger cycled the rotating striker, separately firing the 8-inch, smoothbore barrels with each pull of the trigger. Since the gun was designed to be carried and used in saltwater, it was built using noncorrosive metals and specially coated internals with plastic furniture.

To accommodate the thick neoprene gloves worn by divers operating in subfreezing waters, the trigger guard and combination safety lever and barrel-hinged lock were oversized. Although this weapon was produced in small numbers and tested by the Soviet Navy, it was not adopted, reportedly because the rocket-assisted round was too advanced for the military at that time.

The Soviet’s second generation underwater pistol, the SPP-1 used a simple 4.5mm rimmed cartridge flechette-firing round that used a conventional cartridge propellant. the round was protected against water by a sealant in the neck and a lacquer coating on the primer.

The design team went back to the drawing board and created the SPP-1 pistol. This was basically a cruder version of the B-VI-307 and cheaper to produce. This gun retained the simple break-open design with a cluster of four smooth-bore barrels and double-action trigger, but the rocket-assisted projectile was abandoned in favor of a simple 4.5mm rimmed cartridge flechette-firing round utilizing a conventional cartridge propellant. The round was protected against water by using a sealant in the neck and a lacquer coating on the primer. The flechette also used the cavitation-bubble design and was as equally ineffective above water as the original. The 4.5mm cartridge was effective to 55 feet underwater, and that varied based on the depth. The range decreased as the depth increased. The new design was eventually accepted by the Soviet Navy and entered service in 1971. It is believed that the Naval Forces of the Russian Federation still use this weapon today.

While the Soviets were developing the SPP-1, the United States was working on the design of their M1 Underwater Defense Gun for the US Navy combat swimmers. Much of the development was carried out at the Naval Surface Weapons Center Laboratory in Silver Springs, Md. In what appears to be an amazing coincidence of similarity, the original concept for the US weapon fired a lancejet round. This was a rocket-propelled round based on gyrojet weapons and projectiles. These had been developed commercially some years earlier, but were never taken up or adopted by the military. Like the Russians, the US military decided this round was too innovative, not to mention costly and totally inaccurate above ground, so the idea was scrapped.

The M1 designed the Mark 59 underwater ammunition as an attempt at a more conventional round. The Mark 59 ammunition was contained in a preloaded, stainless-steel, six-round cylinder. The cylinder was 5.5 inches long and was effectively a “pepperbox” configuration with each chamber acting as its own barrel. The six chambers contained a 4.25-inch, heavy-stabilized, tungsten-fin darts, which were propelled from the weapon by a captive piston when the gun was fired. With a muzzle velocity of 738 feet per second, the effective 32-foot range at a depth of about 60 feet was similar to the SSP-1. The frame, action, door assembly and cylinder were all made from lightweight alloys while the other parts were machined from stainless steel and the double-action trigger was made of nylon.

The M1 entered into service in 1970 and was not overly popular, mostly due to its bulky configuration. It was withdrawn from service in the 1980s and replaced by the Heckler & Koch HK P11 underwater pistol.

Heckler & Koch P11

The HK P11 is one of the least-known weapons to emerge from Heckler & Koch’s factory in Germany’s Black Forest. For a long time H&K would not even acknowledge its existence, but recently some details have become available.

Developed during the 1970s to arm the Kampfschwimmer, the commando frogmen of the German Bundeswehr, this weapon has since been adopted by other NATO navies, including those of Italy, France, Norway, the Netherlands, UK and the US.

The P11 and the ammunition is somewhat bulkier than the SPP-1 Soviet counterpart, and just like the US M1 underwater pistol, it uses a detachable pepperbox cluster of five barrels, each factory loaded with a powder charge and a drag-stabilized, flechette-dart projectile. Each projectile is 117mm long and weighs 31 grams with a muzzle velocity of 351 fps.

The H&K P11 used a propellant that was electronically ignited using 9-volt batteries sealed inside the pistol grip.



The pistol is reloaded by replacing the entire barrel cluster. Loaded barrels are protected from saltwater by thin diaphragms, which are destroyed when the projectile is fired. The propellant in each barrel is electronically ignited using 9-volt batteries that are stored in a sealed container inside the pistol grip. The nature of the propellant is still classified information. End users cannot recharge the barrel cluster. It has to be returned to Heckler & Koch to be reloaded.

The effective underwater range depends on the depth, but the maximum is about 50 feet. Above water, the effective range is quoted as being around 65 feet, and while the long and relatively heavy flechette can be lethal at longer ranges, accuracy is minimized by the flechette tumbling and yawing in flight.

Story by Frank Jardim

In 1944, the War Department Basic Field Manual FM 21-75, Infantry Scouting, Patrolling and Sniping defined the sniper as “… an expert rifleman, well qualified in scouting, whose duty is to pick off key enemy personnel who expose themselves. By eliminating enemy leaders and harassing the troops, sniping softens the enemy’s resistance and weakens his morale.” That definition remains consistent through the broader history of sniping, before and since, whether the weapon was a crossbow or a high-powered, telescopically sighted rifle.

Lie and wait

A sniper and spotter settling into a concealed position

The sniper is an incredibly efficient fighter, compared to the typical infantryman. Consider that in World War II, American infantry units fired 25,000 rounds to kill just one enemy soldier. By the Korean War, that figure jumped to 50,000 rounds, and the select-fire M14 and M16 infantry rifles of the Vietnam War only seem to have produced more misses, requiring the expenditure of 200,000 rounds to kill one enemy combatant. Nowadays, it’s a quarter million rounds of spraying and praying to kill a single Taliban.

By comparison, on average, a sniper requires only 1.3 bullets to kill an enemy. During the Vietnam War, it was noted on many occasions that a handful of snipers accounted for more enemy killed than the entire infantry battalion (and sometimes even regiment) they were assigned to.

It was the wildly disproportionate contribution of snipers in the Vietnam War that set the stage for the first permanent peacetime sniper training programs. The U.S. Marine Corps set theirs up first at Quantico, Va., in 1977, and the U.S. Army followed suit at Fort Benning, Ga., in 1985. Snipers were finally on the TO&E (Tables of Organization & Equipment) of combat units, which meant they would always be ready for deployment. The rigorous training programs ensured the accumulated knowledge, gained from combat experience, would be preserved and ready when it was needed.

130326-A-DK678-006Another critically important achievement of the USMC Scout Sniper and U.S. Army Sniper Schools was the creation of the U.S. military’s first purpose-built sniper rifles. Again, the USMC led the way with the M40A1 and the U.S. Army followed with the M24 Sniper Weapons System. Both were based on the Remington 700-bolt action rifle, chambered in 7.62x51mm NATO. Prior to that, snipers used standard service rifles, specially selected for their accuracy and equipped with telescopic sights or commercial, off-the-shelf sporting rifles, as was the case in the black powder era and the Vietnam War. The upside of using the standard service rifle as the basis for a sniper conversion was complete parts and ordnance maintenance support from the normal supply channels. The downside was that the most accurate service rifles were not nearly as good as the best commercially available hunting rifles. The accuracy of the service rifle was always hampered by hand guards, stacking swivels and bayonet lugs hanging off the barrel – items totally useless to a sniper.

It is ironic that a country built on a tradition of rifle marksmanship took nearly 200 years to formally embrace the sniper, the man that represents the military apex of that long tradition. In each major war, through Vietnam, our armed forces began with no snipers and had to create training programs, usually in the theater of operations, to train them on the spot. Training varied from none to good, but the typical formula that has made many a successful American sniper is a rural background with early and continuous exposure to hunting or competitive, rifle shooting.

It is ironic that a country built on a tradition of rifle marksmanship took nearly 200 years to formally embrace the sniper

Time after time, at the conclusion of the war, the sniper schools were closed and the snipers faded away. The knowledge they gained in the deadly art of hunting men faded away with them and had to be re-taught in the next war. This happened because America’s senior military leaders saw the sniper as a specialist, of small importance compared to the conventional infantry, artillery, cavalry (and later armored) forces who massively outnumbered him. From the general’s point of view, snipers didn’t win wars; huge armies did.

During the American Revolution, volunteers from the frontier colonies took their long rifles to war. No British soldier within 400 yards was safe, and 200-yard, one-shot-kills were common. Riflemen terrorized the British, on the march and in garrison, picking off officers and noncommissioned officers from hidden positions. Without any formal guidance, they were doing exactly the same mission as snipers do today, but the British had far greater respect for them than General George Washington. Slow to load and lacking the capacity for a bayonet, the rifles and the unruly men who wielded them were ill-suited to the linear tactics of the day. General Washington thought the riflemen were more trouble than they were worth and didn’t want them in the Continental Army.

Trey Dominick USMC Scout Sniper

 In the American Civil War, snipers were called sharpshooters and recruited for their marksmanship skill. The percussion-lock rifled musket and minie ball of the period greatly increased accuracy, without sacrificing speed of loading, and made the battlefield a much deadlier place. Some sharpshooters made use of early telescopic sights and many used their personal weapons in battle. The breech-loading Sharps rifle was popular among Union sharpshooters because it could be loaded lying down, behind cover. The standard muzzleloading, rifled musket required the soldier to stand up to load it, thus exposing himself to enemy fire. Confederates favored the British Whitworth rifle, when they could get it. With its unique hexagonal-shaped, fast-twisting bore, instead of conventional cut rifling, it fired a six-sided bullet accurately just over a mile. It was the first military rifle built for long range accuracy. A Confederate sharpshooter, armed with a Whitworth rifle, killed Union General John Sedgwick at the Battle of Spotsylvania from a range of 800 yards.

During WW I, the skill sets and standard operating procedures of our present-day snipers were developed and codified in no-man’s land and the trenches. By that time, the bolt-action rifle reached the pinnacle of its development as an infantry weapon. It had a five- to 10-round magazine and fired a much smaller caliber, high-velocity and aerodynamic bullet, propelled by smokeless powder, up to 3 miles.

Once he had a suitable modern weapon, the scout sniper emerged in a form identical to the present day. Now actually called a sniper, he can engage targets at 1,000 yards with more precision than luck. Whether shooting from behind or in front of friendly lines, he selects his hiding place carefully and uses camouflage to conceal himself and his spotter. He may wait for hours or days to get a shot at his target. When and if he does fire, it is rarely more than a few shots before he must move to avoid detection. (Smokeless powder makes it much more difficult for the enemy to locate his position.)

Sniper rifles are now commonly equipped with telescopic sights. Germany, thanks to their world-renowned optics industry, initially dominated the battlefield by putting 20,000 scoped rifles (some of them civilian hunting rifles) in the hands of its best marksmen. The Allied nations had to play catch up. The United States Army fielded the ungainly 6x magnification prismatic Warner & Swasey scope, mounted on the .30-06 M1903 Springfield Rifle. It looked strange and it was clumsy, but it worked. It had over twice the magnification of most scopes of the day.

The rooftops of the buildings in Iraq and Afghanistan created some of the most intensely-hot shooting platforms which created yet another obstacle for these Snipers

 

By World War II, telescopic sights improved and rugged, domestically made ones with fair weather resistance, like the 2.5x-power Lyman Alaskan (military M81/M82), were mounted on the standard .30-06 M1 semiautomatic rifle. The old M1903 Springfield, with an improved 10x-power Unertl scope, served the USMC, and the simplified M1903A4, with a 2x-power M73B1 scope was a substitute standard for both services.

In World War II, the United States was almost continuously on the offensive. Both the Japanese and Germans often used snipers, suicidally, to cover their withdrawals and stall the allied advance. The greatest threat to a sniper is another sniper, so U.S. Army infantry platoons commonly designated a scout sniper in the headquarters section to be employed at the commander’s discretion.

Contrary to our image of the American sniper as a lone wolf on the battlefield, they also fought as platoons. When the Marines invaded Betio in the Tarawa Atoll on Nov. 20, 1943, Lt. William D. Hawkins led his platoon of scout snipers on a mission, far in advance of the main forces. They hunted down, and eliminated, enemy machine gunners and snipers to protect the advance of their fellow Marines at the long pier. They fought with grenades and flamethrowers, as well as precision rifle fire. Lt. Hawkins died in the battle, but his ferocity in combat earned him the Medal of Honor.

The snipers role in the Korean War bore similarities to World War I: static lines, an attrition strategy and costly frontal attacks. Once again, the precision contributions of the hastily trained snipers (now equipped with M1D sniper rifles and 2.2x-power M84 scopes) was overshadowed by the mass slaughter wrought by concentrated small arms and artillery fire. Korea was a big war fought in a small place. If machine guns had trouble stopping human-wave attacks used by the Communist Chinese, what could snipers possibly do?

By contrast, snipers made undeniably significant contributions in the Vietnam War and all the wars that followed it. The nature and scale of combat changed in a manner that favored the sniper. Vietnam was a big war, but only in the aggregate. It was fought in small engagements over a large area and a long period of time. In this environment, the sniper was on more equal terms with the enemy. Combat actions in Grenada, Beirut, Iraq and Afghanistan were likewise small in scale, compared to the World Wars and Korea.

The superior equipment, training and communication of today’s snipers makes them the deadliest warriors on the battlefield. In Vietnam in 1967, USMC scout sniper legend Carlos Hathcock mounted a scope on an M2 .50-caliber heavy machine gun and used it to make the longest recorded sniper kill in history. His 2,286-meter record stood until 2002, when a Canadian sniper broke it by 24 meters in Afghanistan using a MacMillan Tac-50 bolt-action rifle in the same caliber. Hathcock’s improvised, ultralong-range, sniping demonstration was a harbinger of things to come. In 1990 the U.S. Army purchased the .50-caliber BMG M82 Barrett, semiautomatic sniper rifle for use in Operation Desert Shield/Desert Storm in Iraq. Later it would be standardized as the M107. This rifle was used by Army Ranger Sgt. Bryan Kremer in Iraq, in March 2004, to make the 2,300-meter kill that now stands as the farthest for an American sniper. His was the fourth-longest kill shot in recorded history.

For the record, the credit for the farthest kill goes to British sniper Craig Harrison, who made an incredible 2,475-meter shot with an Accuracy International L115A3 rifle in .338 Lapua Magnum. The .338 Lapua round was designed to outrange the powerful .300 Winchester and extend the sniper’s lethality to 1,600 meters. Chief petty officer Chris Kyle used a McMillan Tac-338 bolt-action rifle in .338 Lapua Magnum to make his farthest kill, at 1,920 meters, against an enemy combatant about to fire an RPG at a passing American convoy.

Army Ranger Sgt. Bryan Kremer made a 2,300-meter kill in Iraq that now stands as the farthest for an American sniper.

In World Wars I and II, American snipers were expected to make 600-yard hits. This was reasonable, in light of the limitations of their service-rifle-based sniper rifles, and the ordinary ball ammunition they had to use. Today’s sniper is expected to hit the target at twice that range. The sniper’s skills remain the same, but his tools have greatly improved. Laser range finders, bipods, high-magnification scopes, night-vision scopes, match-grade ammunition, rugged specialty rifles built to take the abuse of combat and deliver competition accuracy, and excellent, often continuous communication, all contribute to getting the bullet where the sniper needs it to go, with greater accuracy than ever before possible.

The film American Sniper has grossed over $250,000,000 as of this writing, making it the most popular war film in American history. Its themes resonate with the public right now and are sure to generate an increased interest in long-range rifle marksmanship that will serve the cause of freedom well in wars to come. The film tells a slightly fictionalized account of the life of the aforementioned SEAL sniper Chris Kyle, who learned to shoot as a boy in rural Texas, perhaps not unlike our sharpshooters of yore, and became one of the most successful snipers in U.S. military history, saving countless American lives on the battlefield with his shooting ability. ASJ
