Inventions that change the way wars in the world

There are inventions that make human life better but are used for war purposes.

The purpose of each battle can be aggression, looting, power struggle or territorial protection, however, whatever the goal, everyone wants to be the winner. To win is not a simple thing as the war as well as the way of fighting has changed a lot since the time when people still used swords and spears.

Since technology, science has evolved, people have been able to use the latest inventions to win battles. In this article, we will review 10 important inventions that have changed, or can say create new breakthroughs in the way of war.

10. Horse cart

Horse cars are not only innovations that change the transportation industry, but also completely change the way of war. Like the ancient tanks, these tanks became extremely scary vehicles on the battlefield, not only stable, but they could also sweep through the crowds of soldiers on the battlefield.

Horse carriages were invented around 3000 BC, but around 1800 BC the new carriage was improved and used during the war. It really became the infantry's fear on the battlefield. These tanks are used most effectively by armies of Greeks and Romans.

9. Gunpowder

Gunpowder was invented by the Chinese in around 800 AD, accidentally invented while trying to find the immortality medicine. Later, the Chinese took advantage of this invention to make explosives, bombs and guns. The Chinese government tried to keep the gunpowder secret, but it was still known and widely used around the world. Although it was the first country to find the formula of gunpowder and manufacture guns and cannon cannon, European countries were the ones who took full advantage of gunpowder with many powerful weapons.

The advent of gunpowder led to the development of cannon and firecrackers, which completely changed the way of fighting. Guns have long range, accuracy and damage are much higher than the bow or crossbow before. Meanwhile, explosives and cannon firepower are very powerful, can cause extensive damage and destroy the most solid walls. This new invention also marks the end of medieval war with knights and swords.

8. The barrel is twisted

Guns are one of the most dangerous weapons, but the first guns have relatively low range and accuracy, making the soldiers still use them at close range. One of the main reasons was that the first guns had smooth barrels, the round bullet after being fired would impact the barrel and change the trajectory as well as not guarantee stability when flying out.

The twist in the barrel was invented in 1800, completely overcome this disadvantage. Inside the barrel of the barrel was created twisted grooves, causing the bullet to rotate after being fired, so the bullet flew in a straight line after getting out of the barrel. Later, the twist barrel is also applied on large guns, increasing the range as well as accuracy.

7. Internal combustion engine

The internal combustion engine is a revolutionary invention that changes the entire world industry, and it contributes to a complete change in the way of war. Imagine if there were no internal combustion engines, there would be no tanks on the battlefield, no aerial fighters and no ships or submarines at sea. All military weapons require energy from burning fuel.

The internal combustion engine was most used in World War I until today. During World War II, the Germans succeeded in building the first tank that could run 100km daily to march from Poland to Russia for 6 months. The first German ballistic missile, the V-2, was also equipped with an internal combustion engine, which marked a major turning point in the war when it was possible to destroy the target 300km in just 5 minutes. Without an internal combustion engine, the steam engine could still be used, but it could only be used to run locomotives or tractors, but could not create powerful war machines like today. .

6. Aircraft

Aircraft is an invention that brought wars to the sky. Italy is the first country to use airplanes for military purposes. In 1911, the Italians used airplanes to spy on and bomb the Turkish bases. Initially the planes were used to spy on the enemy, then the fighters were built to destroy these spy planes, eventually the bombers were used to destroy the cities. , military base.

The plane has completely changed the way of war, not just the battles on the ground or the sea. The bomber also marked a major turning point when it could carry nuclear weapons.

5. Radio

The transmission of information on the battlefield was very important, Napoleon had to use soldiers to command and command more than 100,000 soldiers, even using pigeons to communicate on the battlefield. This takes a lot of time and does not guarantee safety or the possibility of being stolen from military secrets. Radio was born that completely changed the way of communication on the battlefield.

Especially when the army is getting bigger and bigger, the need for communication becomes very essential, radio helps commanders to know the situation of the battle as well as order the soldiers almost immediately. During World War II, Germany's shortwave radio helped them succeed in the tactic of "rapid warfare," connecting aircraft and tank forces to help combat combat uniformly.

4. Radio waves

The radio invention led to another invention that marked a milestone in the military: radios using radio waves. Radar is the first way a soldier can detect an enemy without seeing it firsthand. The radar uses a radio transmitter then retrieves reflected waves (reflected waves after encountering metal objects), thus detecting enemy aircraft or tanks from distance really far.

In 1939, the British built the first military radar system, a 100-meter-high system around the island to detect enemy aircraft. In 1940, this radar system helped the British air force to timely prevent a German bombing plan. Radar also changed the sea war, when warships and submarines were more easily detected and destroyed.

3. Nuclear weapons

Dubbed the invention of the end of all other inventions, nuclear weapons are the most feared weapon in human history ever. Nuclear weapons after being invented and manufactured were used twice. In 1945, the US dropped two atomic bombs on Japan and ended World War II. 'Little Boy' and 'Fat Man' are two fission bombs used by the US, although its response has only been partially implemented but has created a tremendous power, taking nearly 130,000 lives. Japanese people, at the same time its radioactivity leaves many consequences until today.

2. Satellite

During the Cold War, the United States and the Soviet Union were always in a state of concern when their enemies owned nuclear weapons. This prompted the two military powers to develop early warning systems for nuclear missiles. America has pioneered the use of spy satellites to detect enemy missiles.

Military satellites marked the first step in the development of current missile defense systems, helping to early warning ballistic missiles. Besides modern satellites today also have the ability to transmit information and internet signals, helping to connect the military network worldwide.

1. GPS global positioning system

Military furniture helps commanders to easily make tactical plans. The advent of the Global Positioning System (GPS) is like a giant map system, not only that it can also display units of soldiers. The US Department of Defense built the first GPS system in 1990 based on continuous collection of more than 24 satellites.

GPS system also helps to determine the exact location of the enemy, when the soldier only needs to send information about latitude and longitude, from there can deploy bombing raids, or missiles Remote ballistic. In addition to the large battlefields, GPS also helps set up battle maps for soldiers in narrow battlefields such as urban and jungle areas.

Not only that, the GPS system is also used to guide many types of smart missiles, increasing the ability to attack accurately. Unmanned automatic operation systems also apply this technology to guide themselves to goals.
