Recently, an upgraded KC-135 large-scale air tanker of the US Army conducted its first test flight with a "loyal wingman" UAV. The U.S. military believes that this has completely changed the role of tankers in air combat. For a long time, the United States has been used to domineering in the world. In order to remain the number one power, the US military has repeatedly provoked conflicts. Recently, a large number of us warplanes went to and arrived around Russia and began to make tentative provocations. At this critical moment, the successful test flight of the US Air Force's large-scale aerial refueling aircraft has also increased the key strength for the US's hegemonic behavior in the international community.

It is reported that the U.S. military has arrived in the Estonian region around Russia. This time, eight F-15E fighters and two KC-135 air tankers will arrive at emali air force base. In order to participate in the code named "Baltic Trident" military exercises, U.S. aircraft will stay here. Nowadays, with the development of various countries, military strength has become a rigid indicator to measure a country's comprehensive strength. Many countries are also making unremitting efforts to enhance their military strength. After years of development, many emerging countries have quietly risen and become prominent in the field of military development. As for the military strength of all countries in the world, a retired general of the United States said frankly that there are only three countries with top-notch combat power in the world, and the rest are not worth mentioning.

Only the United States, the Soviet Union and China have the strongest military power in the world, said the general, Matthew bunker Richway. Among them, the United States occupies the first position in the world. No matter in terms of Navy or air force strength, the United States has crushed other countries, and 11 nuclear powered aircraft carriers and advanced five generation aircraft have laid the foundation for the development of US military strength.

The second is the Soviet Union. After the collapse of the Soviet Union, Russia has become the largest successor to its military legacy. In the face of repeated provocations from the United States, Russia has always taken a tough stance. Even though its economic development is slow, its military investment and research and development have never been interrupted. It has even overtaken the United States in developing various types of hypersonic weapons, and its strength can not be underestimated. In addition to the "zircon", "dagger" and other weapons, as well as the blessing of nuclear arsenals, Russia has always stood firm in the face of frequent US provocations.

Finally, as a rising star in the field of military development, China's military industrial system and scientific and technological strength are constantly rising through unremitting efforts. In addition, China has become the second largest economy in the world, and is also in a leading position in many fields in the world. In particular, the development of laser weapons and electromagnetic guns also occupies more and more discourse power in the world.
