F-22A Raptor. What does A stand for?

A is the abbreviation of the English word attack, which means attack. The next-generation main aircraft of the U.S. military, with a small number of production, has higher stealth capability and better maneuverability than other third-generation tactical aircraft, so it has another name of battlefield-oriented tactical aircraft. The design concept of head-mounted camera is similar to the compound eye of insects, and it is one of the few models that incorporate tactical aircraft into its main function. Invisibility, host performance and maneuverability are the best tactical machines at present. Because the current tactical aircraft of the U.S. military focuses on firepower projection in cooperation with G-bombs, like other older generation aircraft of the U.S. military, it does not attach importance to the strengthening of melee capability (the U.S. tactical aircraft only have short knives, while China and Japan have long knives). In the 12.5 competition, we fought against the elite rebels who mainly attacked the earthquake with fire, and achieved the exchange record of 7: 0 1, showing the advantages of the body performance. However, due to the overwhelming disadvantage in number and the gap in driving proficiency, many of them were hit by the main rebel forces led by Captain Wu Sha.
