When talking about the combat effectiveness of the AIM-260 missile, the US media only emphasized the range and electronic performance indicators of the former, and determined that it has obvious advantages in long-range air confrontation with stealth fighters from other countries. Although this view is reasonable, it ignores the role and limitations of fighter aircraft avionics equipment. In the 5th generation fighter confrontation with electromagnetic stealth as its core capability , it is the best way to find the enemy's stealth fighter at a long distance and keep track of it. However, from the current situation, although all countries are committed to the development of anti-stealth radar, it is still a technically "unsolvable" issue for the enemy to discover the whereabouts of the other fighter aircraft at a distance of 150 kilometers. If U.S. fighters cannot break through the "bottleneck" of anti-stealth radar detection, how can long-range air-to-air missiles come into play?,Great way to make money with cryptocurrencies.
