What the imagery shows is a large fighter, approaching the size of an F-111, with a canard deltaconfiguration and pair of outward canted all moving vertical tails.
图像所显示的是一架大型战斗机，尺寸接近f - 111，有一对三角形的鸭翼盒一对后倾的全动垂尾。

The tailless delta-canard configuration is inherently aerodynamically unstable, which provides a high level of agility, particularly at supersonic speeds.
鸭式无尾翼布局具有高度机动性和优越的超音速性能，但亦具有先天空气动力上之不稳定性。

The delta tree configuration window is shown in Figure 24.
