Welcome to our top 10 hilariously roundup of the most absurd weapons ever to see the light of day. From over‑engineered cannons that required a whole crew to load, to grenades that could explode in the hand of the user, these firearms prove that sometimes ingenuity goes a little too far. Grab your powder‑horn and let’s dive into the quirkiest, most laugh‑inducing armaments history ever produced.
top 10 hilariously Impractical Firearms Overview
10 Vandenberg Volley Gun
The Vandenberg volley gun was a massive, breech‑loading marvel from the 1860s, conceived by General Origen Vandenberg. Imagine a weapon that could unleash up to 451 .45‑caliber rounds all at once from a single discharge—each barrel had to be loaded individually unless a special loading tool was employed, turning each shot into a painstaking ritual.
Because every barrel needed separate attention, the rate of fire was glacial, leaving the crew exposed for far longer than a typical cannon. The gun was also a heavyweight, difficult to clean, and required a solid crew to manage it, though it managed a respectable degree of accuracy for its size.
Both the United States and Great Britain rejected the design, but Vandenberg managed to sell a few units to the Confederacy. One allegedly saw action during the Siege of Petersburg, Virginia, where its thunderous volley briefly shook the Union lines.
9 Matchlock Musket
The matchlock musket stands among the earliest successful firearms, yet its operation was a logistical nightmare. Loading began by placing a modest amount of powder in the flashpan, sealing it, then pouring powder down the barrel, followed by a patch and a lead ball. The serpentine—a curved metal arm—would drop the burning match onto the flashpan, igniting the charge.
The match itself was a chemically treated rope that had to stay alight at all times, a process known as “tending the match.” Soldiers burned through roughly two kilometers (about one mile) of match cord each year, often lighting both ends to ensure a constant flame, which dramatically accelerated consumption.
This reliance on a living flame created a logistical headache for supply chains and a constant hazard: a stray ember could ignite powder cartridges strapped to a soldier’s belt. The matchlock eventually gave way to the wheel lock and later the flintlock, which eliminated the need for a constantly burning match.
8 Hale Rocket
The Hale rocket, a spin‑stabilized projectile introduced in the mid‑19th century, fired from a metal tube with angled jet vents at its base. These vents, together with tail fins, were meant to spin the rocket for stability, but the system rarely performed as intended.
Invented by Englishman William Hale in 1844, these rockets suffered from erratic flight paths and premature explosions. Their service record is sparse, seeing limited use in the Mexican‑American War, the American Civil War, and the Crimean War.
Occasionally a Hale rocket would even loop back toward its own crew. While militarily ineffective, the sheer unpredictability of these rockets provided a terrifying psychological edge, as foes never knew what to expect when they saw a sudden, soaring fireball.
7 Hanes Grenade
The Hanes grenade—also called the Excelsior—emerged in the early 1860s for the Union Army. Shaped as a hollow metal sphere packed with explosives, it featured ten to fourteen protruding metal pins, each fitted with a percussion cap.
Impact with a hard surface would trigger the percussion caps, detonating the grenade. When unarmed, the grenades were stored in a two‑part metal case that screwed together for safety.
Unfortunately, the design made accidental detonation all too easy, leading to its rejection by the Union. The Confederate forces experimented with similar devices, but none proved reliable. The Ketchum grenade, in contrast, saw successful deployment at both Petersburg and Vicksburg.
6 Double‑Barreled Cannon
Conceived in 1862 for the Confederate Army, the double‑barreled cannon was the brainchild of John Gilleland and cost $350 to produce. It fired two cannonballs at once, linked by a chain intended to spin in flight and slice through anything in its path.
Testing revealed that the two barrels seldom fired simultaneously, and when they did, accuracy was abysmal. One trial saw the cannons demolish a few trees, topple a chimney, and even kill a cow—far from the intended battlefield impact.
Both the Confederate government and the state of Georgia dismissed the weapon as a failure, refusing to adopt it. After a brief, uneventful skirmish, the cannon was retired and now rests outside the city hall in Athens, Georgia.
5 M50 Reising
The M50 Reising, a submachine gun adopted by the United States Marine Corps during World War II, was meant to supplement the Thompson, which was in short supply. Weighing less and cheaper to produce, the Reising fed from a 20‑round detachable box magazine, with a paratrooper variant, the M55, featuring a folding stock.
In practice, the Reising proved ill‑suited for the harsh Pacific theater. Sand and fouling caused frequent jamming, and the gun’s design made field cleaning a cumbersome task.
Compounding the issue, many components were hand‑fitted at the factory, rendering parts non‑interchangeable. This logistical nightmare forced Marines, at one point, to discard their Reisings into a river in favor of the reliable bolt‑action 1903 Springfield. Post‑war, the weapons found a second life with police departments, thriving in less demanding environments.
4 Chauchat
The Chauchat, manufactured for the French army during World I, is often crowned the worst light machine gun ever made. Its bolt would seize up when overheated, rendering the weapon useless until it cooled—a critical flaw in the heat of trench combat.
Equally problematic was its magazine: an oddly shaped, curved container with large cutouts on the right side. Supposedly designed so the assistant gunner could see remaining ammunition, the cutouts instead invited mud and grime, causing chronic jamming.
Operators also had to keep their cheek clear of the recoil mechanism, lest the bolt slam into their face. Some Chauchat variants were chambered in .30‑06 for the U.S. forces, but these suffered even more severe reliability issues than the original 8 mm Lebel models.
3 Bombard
The bombard was a massive, medieval cannon that hurled enormous stone cannonballs—often carved from solid rock—against fortress walls. These behemoths were cast from bronze or assembled from iron bands, and could weigh thousands of pounds, with projectiles weighing several hundred pounds each.
While early bombards could breach castle walls, the stone shot frequently shattered on impact, limiting effectiveness. Their sheer size made transport, aiming, and loading a monumental undertaking, resulting in a very slow rate of fire.
Famous examples include Scotland’s Mons Meg, forged in the 15th century and now displayed at Edinburgh Castle. Over time, bombards were superseded by smaller, more mobile cannons that fired faster, more accurate projectiles.
2 PIAT
The PIAT (Projector, Infantry, Anti‑Tank) was a British anti‑tank weapon introduced in the early 1940s to counter German armor. It fired a hollow‑charge warhead using a powerful spring‑loaded mechanism.
Initially effective, the PIAT’s usefulness waned once German tanks were fitted with metal skirts that caused premature detonation, preventing penetration. Moreover, the weapon’s recoil was notoriously brutal, often leaving soldiers with bruised shoulders.
Firing required cocking a hefty spring by standing the weapon upright—an awkward and risky maneuver under fire. Additionally, the barrel’s build quality was subpar, contributing to a reputation for unreliability. Nonetheless, the PIAT remained in British service through the Korean War.
1 Krummlauf Device
The Krummlauf was a bent‑barrel attachment created for the German StG 44 rifle, allowing soldiers to fire around corners or from within a tank while staying under cover. A periscope mounted on the rear provided sighting, and versions existed with 30‑ and 40‑degree bends.Although innovative, the design suffered from significant drawbacks. Bullets lost velocity as they passed through vent holes meant to prolong barrel life, and the curved barrel caused frequent bullet shattering, producing a shotgun‑like spread and severely reducing accuracy.
Furthermore, the Krummlauf’s lifespan was short; the attachment wore out quickly and required frequent replacement. Despite its shortcomings, it remains a fascinating footnote in small‑arms engineering.
