Came across this while dealing with the Generic German U-boat listing in the CWDB
Missing U Boat guns. Below from Wikipedia...
Type VIIC. 1 × 8.8 cm SK C/35 naval gun[3] with 220 rounds, various antiaircraft weaponry (2 cm (0.79 in)anti-aircraft guns.
"The Type VIIC was the workhorse of the German U-boat force, with 568 commissioned from 1940 to 1945.
The first VIIC boat commissioned was the U-69 in 1940. The Type VIIC was an effective fighting machine and
was seen almost everywhere U-boats operated, although its range of only 6,500 nautical miles was not as great as that of the
larger Type IX (11,000 nautical miles), severely limiting the time it could spend in the far reaches of the western and southern
Atlantic without refueling from a tender or U-boat tanker. The VIIC came into service toward the end of the "First Happy Time"
near the beginning of the war and was still the most numerous type in service when Allied anti-submarine efforts finally defeated the
U-boat campaign in late 1943 and 1944.
Type VIIC differed from the VIIB only in the addition of an active sonar and a few minor mechanical improvements, making it 2 feet longer and 8 tons heavier.
Speed and range were essentially the same. Many of these boats were fitted with snorkels in 1944 and 1945.
They had the same torpedo tube arrangement as their predecessors, except for U-72, U-78, U-80, U-554, and U-555,
which had only two bow tubes, and for U-203, U-331, U-351, U-401, U-431, and U-651, which had no stern tube.
On the surface the boats (except for U-88, U-90 and U-132 to U-136 which used MAN M6V40/46s) were propelled
by two supercharged Germaniawerft, 6 cylinder, 4-stroke M6V 40/46 diesels totaling 2,800 to 3,200 hp (2,100 to 2,400 kW)
at 470 to 490 rpm.
For submerged propulsion, several different electric motors were used. Early models used the VIIB configuration of two
AEG GU 460/8-276 electric motors, totaling 750 hp (560 kW) with a max rpm of 296, while newer boats used two BBC GG UB 720/8,
two GL (Garbe, Lahmeyer & Co.) RP 137/c electric motors or two Siemens-Schuckert-Werke (SSW) GU 343/38-8 electric motors
with the same power output as the AEG motors.
Perhaps the most famous VIIC boat was U-96, featured in the movie Das Boot."
"Type IXB.
10.5 cm (4.1 in) SK L/45 deck gun with 180 rounds on a Utof mount.
The last piece of armament that the Type IXB submarines were equipped with were the standard 2 cm (0.79 in)
anti-aircraft guns.
All Type IXB submarines had 1,000 hp (746 kW) while submerged and 4,400 hp (3,281 kW) when surfaced. As a result they could travel at
18.2 kn (33.7 km/h; 20.9 mph) while surfaced and 7.3 knots (13.5 km/h) submerged. The Type IXB submarines had a range of 12,000 nmi
(22,000 km) at 10 knots (19 km/h; 12 mph) while on the surface and 64 nmi (119 km) at 4 kn (7.4 km/h; 4.6 mph) while submerged.
They had 6 torpedo tubes (4 in the bow, 2 in the stern) and carried a total of 22 53.3 cm (21 in) torpedoes. Unlike the earlier Type IXAs,
the Type IXB submarines were equipped with 44 TMA mines as well. The Type IXB submarines were equipped with a 10.5 cm (4.1 in) SK L/45 deck gun
with 180 rounds on a Utof mount. The last piece of armament that the Type IXB submarines were equipped with were the standard 2 cm (0.79 in)
anti-aircraft guns. All Type IXB submarines could hold up to 56 crew members at any given time though that number was usually around
45–48 crew members. After being commissioned and deployed, all of the Type IXB submarines built prior to the fall of France were stationed
in the German port city of Wilhelmshaven while those who were commissioned following the capture of numerous French ports during the Battle
of France were stationed in Lorient."
