During the war they invented the most important item, the radar. Radars would use sound to track objects and that was very useful. It will know what is coming and where it is. The radio helped people listen to other people's plans but they had to do something so they talked in code and they’re called the code talkers. The Germans wanted to invade the Soviet city of Stalingrad. When it was time to invade they approached a fierce and defensive army and made the Germans surrender. The Soviet Union was heading to Germany to stop the war. In 1943 this started to change, the Allied forces got stronger and started to win the war.

In the world war 2 they used some new things that could help them in the war tanks were also being upgraded because they were first used in world war 1 so with the tanks in world war 2 were being stronger faster and more powerful.
The radar was also important. It helped officers so they could talk to pilots or troops. The radar would sound wave and find objects so when it does it will show up on the screen and its location. They were also used to find enemy aircraft.

That radar was amazing for them because it showed them were things were. The code talker were good for the soldiers in war. The aircrafts were a good the to it help get battles over sea. They built a lots of things to help them to win they battle.

One amazing invention of WW2 was the radar. It really helped them know if there was something coming from afar. It'd be better than a surprise attack. Also the aircraft carrier was another big inention. That made it possible to take of from any place not on land. Obbviosly you had the opition to take.

Radar was one of the most important inventions for war. This invention changed the course for both sides. Now that they had this technology they were able to send signals for help and other things. This was all very good for the Allies but the Axis powers could sneak in and steal the signals of what they were saying. All of this made it very hard for the ALlies and soon they started to make codes but when they made one it was broken by the other side. They tried and finally they found an unbreakable code. It is called the Navajo language and it was chosen because of its complex language and unable to be broken. No matter the cost these code talkers had to be protected and if the enemy found out about it then a lot of lives would be lost.

This is how technology helped in war. let's start with the radar. the radar is very very cool in my opinion. It helped track down enemy bases. Another cool invention is the aircraft carrier. It made it possible to attack an enemy far from any land based runway. one other invention is the tank. The tank had a canon on top and were heavy armored and deadly.

The radar was probably the most important piece of technology that was invented in World War 2. It helped to detect enemy planes in time so people could get out in time. It also helped in air fight too. They had radars installed into their plans so they could tell if someone was sneakin up on them they also added technology to tell if the plane was friend or foe. Bombers also played a part in WW2. They could attack large towns with ease and fly long distances and still have plenty of gas to go even farther.

The radar was definetly one of the most important wartime invention. It was used for many things, but the most important one was it was able to spot enemy aircraft. The radar detected any moving or not moving objects in the sky, or ground. Also, another way they used it was by telling secret messages. These people were code talkers, who told the army forces secret messages in the language Navajo. Although, it wasn't exactly the Navajo language. It was a little bit different. I thought the code talkers topic was really cool. I found out that only four code talkers are alive in 2020. Out of the 400 code talkers, only 13 were killed!!!!

The technology that help them a lot is the radio and because the germans would get on the radio so they us code and the one they used that the germans could never find out what it meant was the Navajo Language. Another technology that helped them is the radar that helped them to spot out the plans that were going to attack them.

I think radar is one of the best wartime inventions ever. Not only were we able to save thousands of more lives but without radar I doubt the Allied powers would have been able to win the war. Another invention that was really helpful was the nuke bomb. But there is one thing I don't like about the nuke. My dad and I were talking about Vladimir Putin and how bad he really is and that the U.S. could probably overthrow him but If we attacked him he would attack us. Then it would just be a giant nuke war because we both nuke and it would get out of hand and Russia would join with china and start bombing innocent  places. That is also the reason there is no giant wars going on right now.

When you look at today's world, with so much technology, you don't necessarily think about not having it. SImple things that make such a big difference like radar. Radar was very important in the war, and still is today. The UK was the first to discover radar, and the Allies had that advantage for a while. When the two sides would go into battles, the radar would help the Allies detect where the bombers were, and how far they were away. In the video on radar, it said that the first time they attempted the radar strategy, the Allies detected a bomber almost 8 miles away! Obviously, our technology today is a lot more high tech, radars for wars nowadays can detect aircrafts up to 2000 miles away. If there was a giant war like WWiii going on right now, we would have a whole bunch of technology and chemicals, and I would assume a lot more people would lose their lives. technology is a great thing, but we cannot let it over power us.

I believe that many good inventions were created during WW2 times. The radar definitely helped out quite a lot in the war. Radars proved very helpful in the war because people could tell in someone or something was coming. Of course this was good and bad because it helped both sides. I feel like it was the most helpful if you were being attacked, then you could send for backup through the radio. The radio was also a helpful invention during the war. Just to be safe, everyone talked in code. The way they did this was amazing and smart. They used the Navajo language. It is so smart because all the Navajo were on the same side. Also, on one else knew the language, which meant the code could never be broken. The worst part of this plan would be if one of the code talkers got captured. They would eventually let the cat out the bag. If they ever found out, about this code, it would be much easier to break. It would be horrible if the Axis ever found out. It would cost many people their lives. With all of the technology that we have in our times, we may not realise how important these inventions were in WW2 times.

I wonder how many times the Allied and Axis forces had to improve their warcrafts. If on side improved then the other side would have to improve immediately or else they would lose very soon. If they did that it would be a back and forth loop of improvement. Now that I know that radios were invented during the war, I think about how many times we take radios for granted. Radios are now toys that kids use to have fun, but during the war radios were very important tools used to communicate overseas or across the country.

World War II witnessed tremendous growth in the size of American military aviation, from about 2,500 airplanes to nearly 300,000 by the war's end. The Museum's collection of 30 World War II-era American military aircraft ranges from propeller-driven trainers, fighters, flying boats, and bombers to the nation's first generation of jet-powered fighters to take to the air. They represent the pilots of the Army Air Forces, Navy, and Marines, as well as the crews who flew them, the support personnel on the ground and at sea who maintained them, and the people who made these weapons of war on the home front. The legacy of their contribution to World War II and the continued enthusiasm for these aircraft still resonates with Americans today.

What is a code talker? A code talker is the name given to American Indians who used their tribal language to send secret communications on the battlefield. Most people have heard of the famous Navajo (or Diné) code talkers who used their traditional language to transmit secret Allied messages in the Pacific theater of combat during World War II. But did you know that there were at least 14 other Native nations, including the Cherokee and Comanche, that served as code talkers in both the Pacific and Europe during the war? The idea of using American Indians who were fluent in both their traditional tribal language and in English to send secret messages in battle was first put to the test in World War I with the Choctaw Telephone Squad and other Native communications experts and messengers. However, it wasn't until World War II that the US military developed a specific policy to recruit and train American Indian speakers to become code talkers. The irony of being asked to use their Native languages to fight on behalf of America was not lost on code talkers, many of whom had been forced to attend government or religious-run boarding schools that tried to assimilate Native peoples and would punish students for speaking in their traditional language.

The US Army was the first branch of the military that began recruiting code talkers from places like Oklahoma in 1940. Other branches, such as the US Marines and Navy, followed a few years later, and the first class of 29 Navajo code talker US Marine recruits completed its training in 1942. Apart from basic training, these men had to develop and memorize a unique military code using their mostly unwritten language, and were placed in a guarded room until this task was completed.

The first type of code they created, Type 1 code, consisted of 26 Navajo terms that stood for individual English letters that could be used to spell out a word. For instance, the Navajo word for "ant," wo-la-chee, was used to represent the letter "a" in English.

Type 2 code contained words that could be directly translated from English into Navajo, and the code talkers also developed a dictionary of 211 terms (later expanded to 411) for military words and names that didn't originally exist in the Navajo language. For example, since there was no existing Navajo word for "submarine," the code talkers agreed to use the term besh-lo, which translates to "iron fish."

Most code talkers were assigned in pairs to a military unit. During battle, one person would operate the portable radio while the second person would relay and receive messages in the Native language and translate them into English. Their work was highly dangerous especially in the Pacific, because Japanese soldiers would deliberately target officers, medics, and radiomen, and code talkers had to keep moving as they transmitted their messages. The work of hundreds of code talkers was essential to Allied victory in World War II, and they were present at many important battles, including at Utah Beach during the D-Day invasion in France, and at Iwo Jima in the Pacific. In fact, 5th Marine Division signal officer Major Howard Connor stated, "Were it not for the Navajos, the Marines would never have taken Iwo Jima."

Despite their heroic contributions during the war, American Indian code talkers were told that they had to keep their work secret. They couldn't even tell their family members about their communications work. Since the codes that they developed remained unbroken, the US military wanted to keep the program classified in case the code talkers were needed again in future wars. Even when the WWII code talker program was declassified in 1968, national recognition of code talkers was slow. While there was some recognition in the 1970s and 1980s, it wasn't until 2001 that Congressional Gold Medals were given to the Navajo and other code talkers.
