On the top of the fuselage of the JU88, there is a clear round window...it looks like it houses a "fan"?

What the heck is it?

In the game it's modelled, but just looks like it's painted on.

Amy ideas?

Navagation dome so the Nav can use his sextant to take a reading on stars? The American bombers had them

Yeah, I also wondered. It looks like some kind of compressor wheel but, I don't think it is that.

It is a radio direction finding antenna. Metal foils in starshape under plexiglass dome.

Thanks! I was wondering that myself. I could never get a good look at it, and every sim I have seen make it look like a surpercharger turbine like on the P-38. It was so odd that I never assumed to know it was. Thanks for clearing it up. I new it was not a supercharger duct or a nav dome. #1, no engine in the middle, #2, no crew behind the cockpit. I had also seen this on other German aircraft (219 UHU? or Do-17? One of those).

How many luftwaffa aircraft have you seen with a real gun turrete? None that I can think of. They liked gunports, but no true electric turretes. They went from gun-port to remote barbettes. No wonder they could not get them to work properly. They skipped the turrete phase! Japan was also like this. No real turretes. The Allied bombers loved electric turretes.

Didn't the FW-200 have a turret?

Just because most people haven't seen any doesn't mean they didn't exist/i/smilies/16x16_smiley-wink.gif The Germans started to install turrents on some of their bombers toward the latter part of the war. Zyzbot is correct in pointing out the the Condor had one. At least in the later versions. If you go to the Focke-Wulf site, you can see a picture of a Fw 200 C-3/U1 with a dorsel turret.

The last bomber variant of the He 111, the H-21 produced in 1944 had a 13mm MG 131 in an electrically operated dorsel turret.

The Dornier Do 217 E series also had the same type of turret in the dorsel position.

Later versions of the Ju 188 had a combination of two 13mm MG 131's in the dorsel position. One was fixed and manually operated and the other was in a turret. I'm not sure if this was electrically operated or not. Unfortunetly I've never seen actual photographs of these varients. All I have are drawings and descriptions from some old books of mine.

You're right in that other planes had remote barbettes. How well they actually worked I could not say. Some were pretty interesting though, like the ones on the Me-210 or 410. Either way, the bombers were usually too small with not enough guns, turrets or not, to make much of a difference I think.

By the way, it's not luftwaffa, it's Luftwaffe/i/smilies/16x16_smiley-wink.gif I'm not trying to sound like an English teacher or in this case a German teacher, nor am I trying to be condesending/i/smilies/16x16_smiley-happy.gif Just trying to make a correction. I'm very impressed with your technical and historical knowledge. I've been enjoying your jousting with other posters over the flying wing debate.

As a note to the original question, I always thought the device on the dorsel part of the Ju 88 was a supercharger of some sort. I could be wrong of course. I do have some good drawings of the construction of a Ju 88 in one of my books. Unfortunetly I loaned it to my brother, so I don't have access to it right now. Sorry.

Condescending, not condesending. Turret, not turrent. Dorsel is technically correct, but dorsal is more commonly used.

Sorry, couldn't resist.

I hate you/i/smilies/16x16_smiley-wink.gif Thanks for correcting me. I was afraid this would happen. Is there a way I can spell check my posts or do I need to whip out a dictionary everytime I'm not sure of the spelling?

Cool! I learn something new every day! I myself LOVE turretes and I think the US had the best. The Brits were BIG with small guns. That one looks very sleek, but only uses 1 gun and has an iron/ring gunsight. Mg 151? Not very effictive for late war.

The late war German remote turretes were a lot better like on the Ju-288 (C5?) but from what I heard, not many of the barbettes on the Me-210/410 worked very well. Too complicated. The US also got into the remote turrete with the P-61 and B-29. Did the brits get into them? I dont remember any aircraft with remote turretes on the British side.

It is the prototype for the Jumo 10088 anti-matter chamber. The Ju-88 was secretly used as a test bed for warp drive, but the Germans never figured out that warp nacells needed to extend away from the hull of the aircraft to produce flight beyond the speed of light. The plans were destroyed in early Allied bomb runs, so the hatch was converted to a cooling fan to keep the overclocked AMD XP3200 chip from overheating. The crews in Africa modified it for creature comfort on their long flights, as they only ran the whimpy Intel chips in their planes. Later it was converted into a vector thrust engine to give the Ju-88 vertical take-off ability.

Actually, I never knew what the heck the thing was, now I do...

Paste it into a "Word" doc, make the corrections and paste it back into your post. Or write it all in Word first.
