The first version had a circular cross-section fuselage, with a small round window in the nose for the pilot's vision. Overall, the entire fuselage was protected by a 5mm armored shell. The pilot lay in a prone position, and the cockpit was very cramped. A removable 140mm (5.5 inch) armored glass screen was mounted in front of the pilot. Two small bulges were located on the fuselage sides for the pilot's elbows. Alongside the pilot's legs were two C-Stoff (one component of the rocket fuel) fuel tanks and by his feet a single T-Stoff fuel tank. The wings were straight and mounted midfuselage, with a stepped bulge above the wings which held the single MK 108 30mm cannon with 60 rounds. The rocket engine exhausted beneath the tail unit which featured a twin fin and rudder setup. A retractable skid could be lowered for landing and a drag parachute (ejected from a hatch on the top rear fuselage) was also to be used upon landing. The aircraft could only be entered from a hatch above the cockpit, so the pilot had to enter the E.381 before the aircraft could be attached to the carrier Ar 234C-2 and had no way to escape in case of emergency.

第一个版本有一个圆形截面的机身，在机头有一个小的圆形窗口供飞行员观看。总的来说，整个机身由一枚5毫米的装甲炮弹保护。飞行员俯卧着，驾驶舱非常狭窄。一个可移动的140毫米(5.5英寸)装甲玻璃屏幕安装在飞行员前面。机身两侧有两个小凸起，是飞行员肘的地方。在飞行员的腿旁边有两个C-Stoff(火箭燃料的一个组成部分)燃料箱，在他的脚旁有一个T-Stoff燃料箱。机翼是直的并安装在机身中部，在机翼上方有一个阶梯式凸起，携带单管MK 108 30毫米炮和60发炮弹。火箭发动机在具有双鳍和方向舵设置的尾部单元下方耗尽能量。一个可伸缩的滑块可以降低用于着陆，一个拖拽降落伞(从机身后部顶部的一个舱口弹出)也将在着陆时使用。飞机只能从驾驶舱上方的舱口进入，因此飞行员必须先进入E.381，飞机才能与航母Ar 234C-2连接，在紧急情况下无法逃生。

The second version was very similar to the first version of the Ar E.381. The overall dimensions were enlarged slightly, but the basic layout remained the same. The front canopy was enlarged, giving the prone lying pilot better vision out of the still cramped cockpit. A slight step still remained aft of the entry hatch atop of the forward fuselage, and a single MK 108 30mm cannon (45 rounds) was still mounted here, firing over the cockpit. The tail unit was similar, with the fins being slightly smaller and rounder. Landing was accomplished by means of a built-in landing skid and the same drag parachute, and the same means of entering and exiting the second version of the E.381 (via a hatch on top of the fuselage) remained from the first version.

With the third E.381 design, the overall dimensions were again enlarged slightly. The fuselage shape was designed as a triangular cross-section now, which presented an even smaller front cross-section. The step above the fuselage was eliminated, and the wing was now a shoulder mount design. Also, the wing tips were turned downwards, to act as skids once the plane landed and tipped from side to side. Instead of a single MK 108 30mm cannon, the third version was armed with six RZ65 or 73 spin-stabilized rockets fired from the wing leading edges. The tail unit was redesigned to sit slightly higher than the fuselage and the fin and rudders changed to a simpler rectangular shape. Landing was the same as the first two versions, via a retractable landing skid and drag parachute. The problem of entering or exiting the E.381 was solved by adding a side-opening hatch on the starboard side of the forward fuselage.

在E.381第三个设计中，整体尺寸再次略有放大。机身形状设计为三角形截面，现在呈现更小的前截面。机身上方的台阶被取消了，机翼现在是肩扛式设计。此外，机翼尖端向下转动，在飞机着陆时起到打滑的作用，并从一边倾斜到另一边。而不是一门单MK 108 30毫米炮，第三种版本装备六枚RZ65或73枚自旋稳定火箭从机翼前缘发射。尾翼被重新设计，比机身略高，尾翼和方向舵也改成了更简单的矩形。着陆和前两个版本一样，通过一个可伸缩的着陆滑块和拖拽降落伞。通过在前机身的右舷增加一个侧开的舱口解决了E.381的进出问题。
