The United States has a high voice in the development of fighter jets. Previously, the United States quickly seized airspace rights in the Gulf War using advanced fighter jets and missiles, which proved the advantage of American fighter jets. For many years, the United States has been developing more and more advanced fighter jets to expand its advantage. So far, the United States is still the only country in the world with two fifth generation aircraft. Moreover, the United States has outstanding performance in various aircraft models such as bombers and transport planes. According to the Global Times citing the Air Force Magazine, Major General Armagorst, responsible for strategic planning and requirements of the US Air Force Global Strike Command, will reveal at the 2022 Nuclear Deterrence Summit that the US Air Force is building up to six B-21 stealth bombers for the next generation stealth bomber project. The prototype is expected to achieve its maiden flight this year.

The outstanding development of American fighter jets has attracted high attention from the outside world. Once the United States has more advanced fighter jets, according to its "personality", it will be more domineering in the world. Therefore, countries are very nervous and are investing more energy in fighter jet development, trying to narrow the gap with the United States. It is worth noting that in order to develop advanced fighter jets, it is necessary to have key aviation technology as support, after all, a fighter jet cannot be without a "heart". The reason why the United States has achieved many good results in the development of fighter jets is mainly due to its advanced aviation technology. It is understood that the F-119-PW-100 engine developed by the United States is a very famous engine in the world, with a thrust of 17 tons. Such data has been highly recognized by the outside world, and many people say that the United States is truly the world's number one.

In order to gain more advantages, the United States has never relaxed its research and development of aircraft engines. The emergence of the GE-9X engine has attracted more attention to the United States. It not only has strong thrust, but also has many advantages that other engines do not have, such as low noise. Moreover, if fighter jets are equipped with this engine, they can also have very strong stealth capabilities, and the flight time of the fighter jet can be greatly extended.

The United States has high hopes for this engine. It is reported that the engine has a thrust of 61 tons, which is three times that of the F-35 and about five times that of the J-20 engine, setting a new world record. However, the engine was not installed on the fighter jet. Experts have analyzed the "abnormal" actions of the United States and believe that this engine is more suitable for large bombers or transport planes. Moreover, due to its limited applicability, this ace fighter jet may not be practical for the United States.

Even so, we can't deny the progressiveness nature of American Airplane. Someone said frankly that if we only look at the engine technology, the United States really has a great advantage, even can lead other countries for 10 years.
