I have a very poor microfilm blueprint scan of the Blohm und Voss P.173.02 long range bomber.

From what I can make out it is a six engined bomber that shares the wings and tail of the BV 238 seaplane.

Does anyone have any good drawings or information on this project?

I'll try to make as clean of a scan as I can at work and post the image I have soon.

Hello

Thank you for sharing: great find !
The only info I have is : "Long range bomber ,six BMW 801"
It seems to have got the BV 238 wings , but it's only a personal guess ...

The P.173.02 looks very very similar to the BV 250 (infact appears to be a terrestial version of the BV 238)

PM me for the original page scans

Google translated from Chronik Eines Flugzeugwerkes 1932-1945 - Blohm & Voss Hamburg, Hamburger Flugzeugbau GMBH by Hermann Pohlmann. Published by Motorbuch Verlag Stuttgart, 1982. ISBN 3-87943-624-X (pages 147, 148, 149)

BV 250
Greater transporter
- Bomber - reconnaissance fighter bomber

Long before the first flight of the BV 238 V-1 had the design office deals with a country version of the BV 238th
On a related project study P 161 was created in March 1942 a detailed construction details »BV 238-land ', later official-type Term "BV 250«.

For various uses could be achieved the following benefits:

1. Under normal transport routes about 2000 km was over 40 tons Load will be charged, for example, two to three 10 tons of heavy armored vehicles. With a relatively small increase of the loading area would be even the transport of a 35 to 40 tons heavy tank have been possible.
2. As a bomber with a flight distance of 7000 km were 20 tons of bombs be carried.
3. As a long-range bomber 4 AQUA tons of bombs was a flight distance of 10,000 km to reach
4. As a long-range reconnaissance of such 14000 km.

From the above in use. Jngszwecken would most notably the large transporters have been of interest because of Normal transporter of the German Air Force The Junkers Ju 52, was for some Transport tasks much too small.

From the flying boat BV 238 has been in the design Build everything except the underwater hull adopted, namely in the dimensions and weights of the BV 238:

DATA TABLE

The main difference to the flying boat lay in the transformation of the underwater vessel to the recording room for the retracted wheelsets of Zentralfahrwerks, the nose wheel and dropping loads large caliber. Since the body only a width of 3.5 m had was the gauge of the undercarriage a row of six in three rows arranged Doppelradsätzen (total twelve o'clock wheels) is not large enough for a sufficiently high roll stability. These could only be achieved through two Supporting wheels, articulated the aspirations of the in the outer wing retractable supporting swimmers.

The total package of Combination was about six meters, a rather daring design. The effort, from the terms Design and manufacture complete BV 238 flying boat with as little Redesign, a new, multi - to-use and fast lieferbares Make land plane, forced to Compromises, for what should be a long-range bomber or long-range reconnaissance with the large Cargo space? And for the heavy-truck 150 soldiers with full equipment or two or three 10-ton tanks for relatively short flights
- Was actually the entire top deck with recreation area, kitchen, etc. superfluous.

Engine plant, equipment and weapons

BV has been taken over by the 238th The redesign of the hull bottom and the re-development of the chassis have been carried out, the manufacturing was not started.

I do not know if buy the BV 250 relationship to the P.173. I have Horst Lommel's brand new book on the BV 238. There is a detailed drawing of the BV 250.
Different body style and different engines. Wings mounted mid-fuselage on the P.173, not flush to the top of the fuselage as on the BV 250. No mention of the P.173.

The only relationship I find is the tail, wings, and outer wing gun pods, which were also slated to go on the BV 238

Here is my tracing from the original.

I also did an overlay of the BV 238 (Same shape as the BV 250) as a comparison. Not that this is an entirely different design then the BV 250.

There is another project that share some similar design features - BV 187. This is mentioned in "Secret German Aircraft Projects of 1945 - Based on British Air Intelligence Reports" by Toros Publications (page 34). It is a land version of the BV 222 - 6 X BMW 801E. Let me know if you want the 3-view scan.

Hope this helps :)

Could be manned but could they also be remote controlled?

I’m just talking about the overall aircraft any specs or more drawings, sorry for only mentioning the gunner positions, thanks
