It was produced by France in 1832. It was invented by Henri-Joseph Paixhans, a French artillery officer. Using 500 kg bombs, the Monster Mortar was used to terrible effect in the Siege of Antwerp in 1832. [h=2]Schwerer Gustav and Dora Worlds Largest Caliber Rifled Weapons[/h] Image Source Schwerer Gustav and Dora were the names of two massive World War 2 German 80 cm railway siege guns. These were the largest caliber rifled weapons in the history of artillery to see actual combat and fired the heaviest shells of any artillery piece. The Little David mortar of the US surpassed these railway siege guns in caliber but it was never used in actual combat. These railway siege guns weighed almost 1,350 tonnes and could fire shells weighing seven tonnes to a range of 37 kilometers. [h=2]Karl Gerat Worlds Largest Self-propelled Weapon[/h] Image Source Karl-Gerat was the largest self-propelled weapon to see service. It was a World War II German self-propelled siege howitzer designed and built by Rheinmetall. This 124 to vehicle was used in attacking Soviet fortresses, in bombarding Polish resistance and participating in the Battle of the Bulge. Only two exist today, the others were scrapped after the war. [h=2]Tsar Bomba Worlds Largest and Most Powerful Nuclear Weapon[/h] Image Source The Tsar Bomba of the former USSR is the largest and most powerful nuclear weapon ever detonated with a mass of 27 short tons (24,000 kg). It zone of total destruction is 35 kilometer radius and its fireball has a radius of 3.5 kilometers. Image Source It was originally designed to have a yield of about 100 megatons of TNT; however, the bomb yield was reduced to only 50 Megatons one quarter of the estimated yield of the 1883 eruption of Krakatoa in order to reduce nuclear fallout. The most powerful weapon ever constructed by mankind was exploded on October 30, 1961, in Novaya Zemlya archipelago in the Arctic Sea. [h=2]Father All of Bombs Worlds Most Powerful Conventional Weapon[/h] Image Source The Russian-made air-delivered/land activated thermobaric weapon nicknamed "Father of All Bombs" (FOAB) is officially named Aviation Thermobaric Bomb of Increased Power (ATBIP). It is the most powerful conventional weapon in the world. This ultimately destructive weapon kills everything that is alive. All that is alive merely evaporates. It is 4-times more destructive than the USs Mother of All Bombs. The bomb was successfully tested on September 11, 2007. [h=2]Mother of All Bombs One of the Worlds Most Powerful Non-nuclear Weapon[/h] Image Source The American-made Mother of All Bombs is officially named GBU-43/B Massive Ordnance. This 9.17 meter-long weapon is a large-yield conventional bomb is regarded as the most powerful non-nuclear weapon ever designed at the time of its development. It has a diameter of 102.9 cm and weighs 10.3 tonnes. Its blast radius is 137.61 m and capable of destroying 9 city blocks. It was field-tested on March 11, 2003 at Eglin Air Force Base in Florida, USA. It is reported that a larger version of the MOAB exists, weighing 13 tons. [h=2]B53 One of the Most Powerful Warheads in the World[/h] Image Source The B53 nuclear bomb is one of the most powerful warheads in the world. It is no longer in active service but 50 are retained as part of the "Hedge" portion of the Enduring Stockpile. The B53, which was built by the US, has a yield of 9 megatons of TNT (38 PJ) is one of the last very high-yield thermonuclear bombs in U.S. service. Image Source This 3.8 meter long bomb has a diameter of 1.27 m and weighed 4,015 kg. It had five parachutes: one 1.5 m pilot chute, one 4.9 m extractor chute, and three 14.6 m main chutes. . [h=2]B41 (Mk-41) - Most Powerful Nuclear Warhead Ever Developed by the United States [/h] Image Source The American-made B41, a thermonuclear weapon deployed by the US Air Command in the 1960s, was the most powerful nuclear warhead ever developed by the United States. Together with the EC17/Mk-17 and the EC24/Mk-24, they have a theoretical maximum yield of 25 megatons. The Mk-17 was also the largest by size and mass: about 20 short tons or 18,000 kg. B41 (Mk-41), a gravity bomb had a mass of 4800 kg, retired in 1957. B41, which was 3.76 m in length with a diameter of 1.32 m and a weight of 4,850 kg, was carried only by the B-52 Stratofortress and B-47 Stratojet. [h=2]Agni Missiles Most Powerful Missiles in the World[/h] Image Source Agni Missile III is considered as the most powerful missile in the world. This medium to intercontinental range ballistic missile developed by India has a 4500 km. range. It has been tested 3-times and the results were successful making Agni-III one of the most accurate strategic ballistic missiles of its range class in the world. A more powerful variant, the Agni V, which is under development, is an ICBM missile with a range of 5000-6000km. Agni III weighs 55,000 kg, a length of 17 m and a diameter of 2 m. It can attain a speed of 5-6 km/s. The missile on the above photo is an Agni II. [h=2]Shabab 5 & 6 Missiles with the Longest Range[/h]See Image HERE The Shahab 5 & 6 which belongs to Iran has a range of 10,000 km. According to intelligence reports, if these bombs have a range of 10,000 km, then they are capable of reaching the eastern coast of the US and most of Europe. These missiles are three-stage rockets will rely on stored propellant liquid fuel for the first two stages with the last solid fuel stage. [h=2]P-800 Oniks - Powerful Russian Supersonic Anti-ship Cruiser Missile[/h] Image Source The P-800 Oniks is a very powerful Russian supersonic anti-ship cruise missile. This missile can reach cruising speeds of Mach 2.9 and Mach 5.7 in a dive. The incredible terminal-velocity of a single Onyx missile, codenamed SS-N-25 Onyx by NATO, makes it a threat to any Aegis warship. This 3000 kg missile with a length of 8.9 meters and a 250 kg conventional warhead would sink a US carrier.
