One of my favorite aircraft of World War II is the German Junkers Ju-88. It saw service on every front where the Germans were engaged and was used in a number of roles.
The Junkers Ju 88 was a German World War II Luftwaffe twin-engined multi role combat aircraft. Designed by Junkers Flugzeug- und Motorenwerke (JFM) in the mid-1930s to be a so-called Schnellbomber ("fast bomber") which would be too fast for any of the fighters of its era to intercept, it suffered from a number of technical problems during the later stages of its development and early operational roles, but became one of the most versatile combat aircraft of the war. Affectionately known as the "Maid of All (Work)" (Mädchen für Alles), the Ju 88 proved to be suited to almost any role. Like a number of other Luftwaffe bombers, it was used successfully as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and even, during the closing stages of the conflict in Europe, as a flying bomb.

Despite its protracted development, the aircraft became one of the Luftwaffe's most important assets. The assembly line ran constantly from 1936 to 1945, and more than 16,000 Ju 88s were built in dozens of variants, more than any other twin-engine German aircraft of the period. Throughout the production, the basic structure of the aircraft remained unchanged. - Wikipedia
And yes, I did have at least one model of a Ju-88 as a boy.

As you can see by these photos, the Ju-88 provided rather cramped working quarters for the crew. You might also notice that all four crewmen are together in the cockpit area, unlike the more spread out layout of an American or British bomber of the time. This was intentional, the Germans did this for morale reasons.

Spitfire and Hurricane pilots liked this layout during the Battle of Britain. One sustained burst into the cockpit area (all that glass!) and you've probably killed or disabled the entire crew. I wonder what the Ju-88 crew's morale was like after such an event.

You can clearly see in this how all four crewmen are bunched together.

The Ju-88's closest counterparts on the Allied side were the Mosquito and the Beaufighter. All three were extremely versatile and useful aircraft.

The Ju 88 was certainly an excellent aircraft. It was easy to fly, gentle, responsive, and manoeuverable, without vices. These were the characteristics which also made it an excellent nightfighter. A point of criticism for allied test pilots was the cockpit. The extensive framing of the many panels resulted in a fairly restricted view. In the bomber versions it was also rather cramped and inefficient, although the close grouping of the crew made communication easier. (Source)
Ju-88 Variants
  • Ju-88 A-series: Main bomber type with Jumo 211 engines.
  • Ju-88 A-0: Pre-production aircraft.
  • Ju-88 A-1: Initial production variant. 895 kW (1,200 hp) Jumo 211B-1 engines
  • Ju-88 A-2: Jumo 211 G-1 engines.
  • Ju-88 A-3: Conversion trainer. Dual controls.
  • Ju-88 A-4: Improved variant. Longer span wings, due to rounded wingtips. Modified with new bomb dropping equipment to produce a A-15 "special" bomber variant. The Ministry of Aviation refused to authorise mass production of the A-15, as the wooden bomb bay "bulge" caused too much drag and a thus a reduction in speed.

  • Ju-88 G-1: BMW 801 radial engines with 1700 PS, FuG 220 Lichtenstein SN-2 radar
  • Ju-88 G-6: Junkers Jumo 213A inverted V12 engines with 1750 PS, used either FuG 220 Lichtenstein SN-2 90 MHz or FuG 218 Neptun 158/187 MHz frequency radar, either with the usual Hirschgeweih eight-dipole aerial setup or experimentally with the more aerodynamic Morgernstern tripled crossed-dipole aerials. Some very-late-war aircraft equipped with experimental FuG 240 Berlin cavity magnetron based 3 GHz radar, with dish antenna in bulbous solid nose. Optional with Schräge Musik upward firing guns with two 20 mm or 30 mm guns.
Night fighter version. The "antlers" sticking out of the nose are actually the radar antennae.
  • Ju-88 G-7: Identical to G-6, but with Jumo 213E high-altitude engines, planned for use with FuG 218/220 with Morgenstern array or FuG 240. The G-7 was also to be installed with wings from the Junkers Ju 188.
  • Ju-88 G-3, 4 and 8 not produced.

Yes, quite a few variants off of the same basic airframe. There is a museum in the UK which I need to visit someday, they have the nose of a KG-54 Ju-88 on display. The Shoreham Aircraft Museum in Shoreham Village, Sevenoaks, Kent.

One of the oddest uses for the Ju-88 was in the Mistel project.
Mistel (German for "mistletoe"), was the larger, unmanned component of a composite aircraft configuration developed in Germany during the later stages of World War II. The composite comprised a small piloted control aircraft mounted above a large explosives-carrying drone, the Mistel, and as a whole was referred to as the Huckepack ("Pick-a-back" in British English, "piggyback" in American English), also known as the Beethoven-Gerät ("Beethoven Device") and Vati und Sohn ("Daddy and Son").

The most successful of these used a modified Junkers Ju 88 bomber as the Mistel, with the entire nose-located crew compartment replaced by a specially designed nose filled with a large load of explosives. The upper component was a fighter aircraft, joined to the Mistel by struts. The combination would be flown to its target by a pilot in the fighter; then the unmanned bomber was released to hit its target and explode, leaving the fighter free to return to base. The first such composite aircraft flew in July 1943 and was promising enough to begin a programme by Luftwaffe test unit KG 200, code-named "Beethoven", eventually entering operational service. - Wikipedia

A very versatile aircraft, one of the Sarge's favorites. Of course, I have so many favorites, expect to see all of them here on the blog, eventually...

This film ends abruptly as it's part of a longer program, but it's interesting. (Somewhat better than one I found on a Japanese website which goes from discussing the Ju-88 to the Fw-200 Condor practically in mid-sentence! Gave me a headache it did.)

Tank Buster!


  1. Interesting!
    Regarding "Fighter aircraft are awesome, but bombers need love too..." I was always prepared to give (bad guy) bombers a little love....6000 times a minute!

  2. Another great post. The engines were liquid cooled, but I don't see where the radiators were located. Google, at least with my skills, isn't much help.

    1. The radiators were just behind the propellers and just forward of the engines.

      From Wikipedia
      The choice of annular radiators for engine cooling on the Ju 88, which placed these radiators immediately forward of each engine and directly behind each propeller, allowed the cooling lines for the engine coolant and oil-cooling radiators (integrated within the annular design) to be just about as short as possible. The concept may have led to a number of other German military aircraft designs adopting the same solution, such as the Arado Ar 240, Heinkel He 177, Heinkel He 219, the inline powered developments of the Focke-Wulf Fw 190 and the twin-engined Focke-Wulf Ta 154.

      Search for radiator on that Wiki page. There's a picture of a wrecked Ju-88 which shows the radiator pretty clearly.

  3. Thank you. Makes sense; wonder why Allied designers didn't use them.

  4. Great report! Thanks. Have a 3 volume set of history of the FW-190 and variants, much like what you reported. Curious your thoughts on the UHU night fighter...;)

    1. Expect to see the Uhu in a future post. One of my favorites, first operational aircraft to have ejection seats!


Just be polite... that's all I ask. (For Buck)
Can't be nice, go somewhere else...
