Does anyone have anymore data on the specifications of this design? Crew, displacement, range, etc.

Looking at the deck plans the armament would be:

Projekt 50

Torpedo Armament: 10 50cm torpedo tubes (all submerged when surfaced) with 28 torpedos; four bow (four reloads), two (trainable) angled to either port bow or starboard bow (six reloads), one each angled to port aft and starboard aft and two aft (eight reloads, including for aft angled tubes)

Gun Armament: 4 15cm U-Boat guns with ~2,500 15cm rounds

IIRC,

    The approximate displacement was 3800 tons surfaced, 4300 tons submerged. Speed was estimated as 25 knots surfaced, 9.5 knots submerged. The problem with UD-1 ( Projekt 50 ) is that for many years all orginal info was thought to be destroyed. The Dreadnought Project drawing was captured by the Russians and was not returned to Germany until the early 90's.

Thus some of the published material concerning torpedo tubes and the number of guns are incorrect. The Projekt 50 drawing is very detailed and one would assume the design was at least nearly finalized.

Anybody have some more pictures of that model?

This was a WWI project?

EDIT: I wonder if work on this design led to Project 50/UD-1 (also referred to in some sources as Type 44).

Thanks moin1900! You found a couple of very interesting projects indeed.

The rear tower seems to be two smokestacks.  Was this steam powered?  Was this design related to the German cargo submarines?
