Thanks
This last one is the best model to put in the game
as its historic performance figures are already good enough for patrol use in short range operations, i.e. the North Sea or Western Approaches departing from Norweguean bases in 1944/45
It also was equipped with a schnorkel
that allows saving hydrogen peroxide for the attacks and evasions.
The relevant figures for modelling this uboat:
Dimensions:
Length: 41,45 metres
Width: 4,5 metres
Depth under waterline: 4,3 metres
Propulsion:
1 (8 cylinder) supercharged diesel engine 230CV@1390 rpm
1 AEG electric engine 78CV@170 rpm
2 Walter turbines 2x2500CV@14500 rpm
Single Screw with 3 blades, 1,75 metres diametre
Speed:
Surfaced (diesel): 8.8 knots
Submerged (electric): 5 knots
Sumerged (Walter turbine): 25 knots
Endurance:
Surfaced (diesel): 3000 miles@8knots
Submerged (electric): 76 miles@2knots
Sumerged (Walter turbine): 123 miles@20knots / 163 miles@15knots
Weapons:
2xTorpedo tubes. 1 reload per tube (4 torpedos in total, 2 in tubes, 2 stored)
Diving depth:
Standard: 80 metres
Crush Depth: 150 metres
Periscopes:
2
Crew:
16 men
Constructed boats:
12 were ordered (U-1405 to U-1406) to Blohm & Voss and 3 were actually completed, but they did finally not enter war service:
U-1405 Dec 1944
U-1406 Feb 1945
U-1407 March 1945
According to those numbers, the only departure from historical reality would be to actually conduct a war patrol with them. But at least one was ready for combat in Dec 1944
even if due to shakedown and training, as well as the need to construct hydrogen peroxide storage facilities in the flotillas bases prevented them from actually making it to the front.
