So, waiting for the surprise B) , an illustration of the BT 1400 riddle.

1. Most common representation, continuously being repeated by scale plan authors and model makers. Very close to an enlarged BT 700, while warhead dimensions are completely different from available data, e.g. the conical section is too long.
2. OP-1666 - interesting representation of the fins, while the warhead is far too slim.
3. A 1963 drawing from Der Flieger, presented above. Even more interesting tail section. :)
4. Original German drawing of the Ar 234 armed with BT 1400. I am sadly unable to interpret details of the the tail section, which seems to be surprisingly complex in shape. Warhead dimensions and fin span are perfectly accurate, though. Also the suspension lug placement matches centre of mass location.
5. My own proposition based on OP-1666 and Ar 234 drawings.

Hello,

today Polish Navy Museum in Gdynia organised recovery of 2 Bombentorpedoes type BT1000 from ex-Torpedowaffenplatz Gotenhafen Hexengrund (today Gdynia Babie-Doły).
So far it looks that these pieces are the only one existing till now.
2 BTs were without engine which was recovered earlier. It has solid propellant. There was no fins attached to the main body.
We hope some new items to be found in future  ;)

I'm somewhat surprised that the Soviets overlooked them.

It was covered by earth. Due to the fact it was inside gorge where the ground still is unstable it poped-up itself.
I think some could be abonded by German and later captured by Soviets but there are not good sources on this subject.

Here are close-ups on second survived engine from BT.
It seems that it's peeled off external skin.

Any inference to the squall (Skvall ?) rocket torpedo?

None.
The engine was intended for increasing velocity after release from an aircraft, thus flight distance.

Yes, it is. What a shame.

And a kind of rough reconstruction, made years before the BTs were recovered. :)

Fw 190 F-8/U2 (renamed into Fw-190 F-8/R15 in the end of 1944) had to carry two BT 400 under the wings. A handful of these aircraft was actiually delivered to III./KG 200 till April 1945.
Ar 234 B-2 was also considered in the summer of 1944 for carrying two BT 400 under the nacelles (plus Magirusbombe gun pod under the fuselage).
