The body design of heavy armor attaches importance to armor and durability. Representative airframe: F-4, F-5 and their derivative models (such as Sniper 8, Ruihe, etc.). ). The second generation

Summarizing the experience and lessons of the Battle of Vaglio, Europe (the first human hive attack, the tactical aircraft troops were completely destroyed within a few hours after entering the underground structure), the development of the second generation shifted the proportion to mobility, and the use of heat-resistant bulletproof composite armor was limited to key parts, and the mobility was improved by lightening the body and strengthening electronic equipment. Representative airframes: F- 15, Su -27 and 10.

third generation

The second generation design idea will be further developed. New materials and composite materials are adopted to further reduce the weight of the airframe, the miniaturization of main components makes the airframe slim, and the data link is improved to make it high-speed and large-capacity, further improving the maneuverability and cooperative combat capability. The third generation has not only greatly improved its mobility, task flexibility and quick response ability. In addition, considering the possible war between human beings after expelling Beta, the United States increased its stealth capability when developing the third-generation tactical aircraft F-22. Of course, this ability is useless for BETA operations, but it has overwhelming combat power for tactical aircraft. Representative models: F-22, fire of ignorance, gust (gust).
