The Mistel ("Mistletoe"; also called Vater und Sohn, "Father and Son") was a German composite weapon system pairing an unmanned Junkers Ju 88 bomber (carrying explosives) with a piloted Bf 109 or Fw 190 fighter mounted on top of it. The pilot in the fighter steered the entire combination to the target area + then detached, leaving the Ju 88 to fly remaining distance under autopilot before crashing into the target. About 250 Mistel composites were built between 1943 and 1945 at Junkers + several Luftwaffe depots. The system saw in-service combat use 1944-1945.

The Mistel S1 (Ju 88A-4 + Bf 109F-4) carried 3,500 kg of explosive (replacing the Ju 88's normal crew + bomb load with a hollow-charge warhead in the nose). Maximum speed limited by Ju 88's performance (~430 km/h). Range ~1,800 km. The Mistel S2 (later variants with Ju 88G + Fw 190) carried up to 8,500 kg of explosive. The combination was used as an unmanned guided missile — the fighter pilot acted as the guidance system + then escaped to fly home.

Mistel combat use was concentrated 1944-1945 against Allied targets. Operations included attacks on bridges across the Oder + Vistula rivers (Eastern Front 1945), against Allied invasion shipping in the English Channel (June 1944 — coordinated with the V-1 + V-2 campaigns), and against Allied airfields in France. Mistel operations were tactically successful when targets were stationary + lightly-defended but ineffective against mobile or well-defended targets. Allied air superiority by late 1944 made Mistel sorties extremely costly to the Luftwaffe. About 0 complete Mistel composites survive; individual Ju 88 + Bf 109 components survive separately.

For Kids — a shorter, friendlier version

The Mistel was a strange German weapon from World War II. The German word means 'Mistletoe.' The Mistel was actually two planes joined together — a small fighter on top of a big bomber filled with explosives.

The bomber was usually a Junkers Ju 88. Its crew was removed and the bomb bay was replaced with a huge explosive charge in the nose. A fighter plane like a Bf 109 or Fw 190 was mounted on struts above the bomber. The fighter pilot would fly the whole stack toward the target.

When the pilot got close enough, the fighter would unhook from the bomber. Then the bomber would fly the rest of the way on autopilot and crash into the target. The fighter pilot would fly home safely.

About 250 Mistel pairs were built between 1943 and 1945. Each Mistel carried 3,500 kg of explosives — heavier than three small cars combined. The Mistel was about as long as a city bus. The Germans tried to use Mistels against Allied bridges and ships, but the system was complicated and most missions failed.

Fun Facts

Most Mistel missions failed because the system was so complicated.

Kids’ Questions

Why did the Germans build the Mistel?

By 1943, Germany had many old Ju 88 bombers and a shortage of trained crews. The Mistel idea let them turn an old bomber into a one-use giant bomb without needing a bomber crew. One fighter pilot could steer the entire stack, drop off the bomber, and fly home.

Did the Mistel work?

Not really. The fighter pilot had to steer the bomber's weight and his own plane at the same time, which was very hard. Many Mistels crashed during takeoff or were caught by Allied fighters. A few hit their targets — like bridges over the Oder River in 1945 — but the system was just too complicated to be useful.

Variants

Mistel S1 (Ju 88A + Bf 109F): Original variant. 3,500 kg explosive. About 100 built.
Mistel S2 (Ju 88G + Fw 190): Improved variant. Up to 8,500 kg explosive. About 150 built.
Mistel S3 (proposed Ju 287 + Me 262): Late-war proposal pairing jet bomber + jet fighter. Not built before war's end.

Notable Operators

Luftwaffe Kampfgeschwader 200 (KG 200): Principal user. Specialised composite-aircraft operations 1944-1945.

Frequently Asked Questions

How did the Mistel work?

The pilot in the upper Bf 109 or Fw 190 fighter started both aircraft, controlled both engines, took off, climbed to altitude, and steered the combination toward the target. At a release point (~5 km from target), the pilot armed the Ju 88's autopilot, separated the fighter from the Ju 88 (using explosive release mechanisms), and flew the fighter back to base. The unmanned Ju 88 continued under autopilot toward the target + detonated on impact.

Was the Mistel effective?

Mixed. Against stationary lightly-defended targets (bridges, fixed installations) the Mistel could deliver large explosive payloads accurately. Against mobile or well-defended targets the system was vulnerable to Allied fighters (the slow Ju 88 carrier was easily intercepted before reaching the target). Eastern Front bridge attacks 1945 were tactically successful but did not affect overall war outcomes. The 1944 attempted use against Allied invasion shipping in the English Channel was largely a failure.
