25 Most Powerful Weapons In History

Posted by on July 29, 2013

What makes a weapon powerful? The word powerful can be very subjective in this case. Causing massive annihilation is powerful but so is inciting fear in a prolonged and painful manner. Anything that can destroy lives and properties is powerful, conversely anything that can protect lives and properties from these 25 most powerful weapons in history is also equally powerful. There is no stopping any country or institution from proving to the world how powerful they can be whether by destroying their enemy or protecting their own.


Maxim Machine Gun

A self powered machine gun that could fire 600 rounds per minute which is equivalent to the firepower of 30 contemporary bolt action rifles. It has mostly been associated with British conquests and was famously used when 700 British soldiers fought off 3,000 warriors with just four Maxim guns in the Battle of Shangani.


Pumhart von Steyr

With a ball diameter of 80 cm, this super gun was the largest weapon used in 15th century Austria. Heeresgeschichtliches Museum at Vienna houses this monstrous bombard today.


Monster Mortar

The world’s largest cannon ever has a caliber of 975 mm. Created by Joseph Paixhans, this monster weapon staked its notoriety during the Siege of Antwerp in 1832.


Tsar Cannon

This engraved cannon is the largest howitzer ever made. It weighs 38 tonnes and is 5.34 meters long. Built in 1586, this massive weapon is now being displayed at the Kremlin in Moscow Russia.


Mark I

The first war vehicle to be called a tank could carry 5 machine guns and 8 soldiers. Mark I had several upgrades numbered II to X but all bore the same resemblance to their “Mother”. This massive tank and its variants were used by several countries throughout the First World War.


Karl Gerat

This mean machine created by Rheinmetall for the Nazi war machine was the largest self-propelled weapon to be used in actual attacks during World War II.


Schwerer Gustav and Dora

These two humongous World War II era German 80 cm railway siege guns are the largest caliber rifled weapons in history used in live combat and its shells are the heaviest of any ammunition ever.



The Ruchnoy Protivotankovyy Granatomyot or hand-held anti-tank grenade launcher or simply the RPG is the most widely used anti-armor weapon in the world. Used by both militaries and insurgent groups, RPG’s even the battlefield out against opponents with more heavy artillery.


B41 (MK-41)

This gravity bomb is the United States’ most powerful nuclear warhead ever but has already been retired in 1957. The only 2 bombers that carried it were the B-52 Stratofortress and B-47 Stratojet.


P-270 Moskit

With a top speed of Mach 3, this Russian supersonic ramjet powered cruise missile makes it hard for enemies to counter attack. Not only that, because of the active military weapons’ secrecy, little is known about it’s background except for some measurements, calculated speed and a few other bits of very basic information.


P-800 Onyx

Other than the fact that its recorded speeds are between Mach 2.9 up to a whopping Mach 5.7 making it way faster than the previous item on this list, this Russian supersonic anti-ship cruise missile can also effectively sink a US carrier. That’s powerful.


Shabab missiles

A class of long range Iranian missiles that could potentially reach up to 5,000 km, Shahab missile upgrades are shrouded in secrecy but the assumption is that they would be used during a possible invasion by Israel.


The Agni missile is a family of medium to intercontinental range ballistic missiles developed by India, named after one of the five elements of nature.

Fat Man and Little Boy

We all are familiar with the Nagasaki and Hiroshima bombings that changed the course of history during the last World War. Named after film characters, these two infamous nuclear bombs gave humanity a shocking memory of what warfare can do to a nation and its future generation.



The 9 megatons of TNT in B53 staked their claim as the most powerful warhead ever. It is one of the last very high yield thermonuclear bombs in the U.S. service but is no longer used actively.
