從 B - 2 到 B - 21，再到 NGAD 未來戰機計劃，美軍多款軍機采用無尾翼設計，這種設計究竟有什麼優勢？水平尾翼與垂直尾翼的消失，給飛機性能帶來怎樣的改變？
雖然這種設計在增強戰機隱身、減輕重量等方面優勢顯著，卻也在飛行穩定與起降等方面面臨挑戰。
From B-2 to B-21, and then to the NGAD future fighter program, many US military aircraft adopt tailless design. What are the advantages of this design? What changes will the disappearance of horizontal tail and vertical tail bring to aircraft performance?
Although this design has significant advantages in enhancing stealth and reducing weight, it also faces challenges in flight stability and take-off and landing.
