Available U-Boats
For the performance differences between the various U-Boat types, please see the table in Submarines.
In addition to the Renown Cost for each U-Boat type, there are also restrictions according the flotilla; that is, only certain U-Boat types are available to certain flotillas.

Available Torpedoes
I'm not sure what the difference is between the prototype dates and the regular dates. Maybe something with accuracy or effectiveness.

Component Upgrades
Deck Guns
Some U-Boats may be fitted with a deck gun. This weapon was used for sinking ships (or finishing off ships crippled by a torpedo, but still afloat) while the U-Boat was surfaced. Deck guns may only be used in calm weather. (Wind speed 6 metres per second or less.)
The type of deck gun that is fitted depends on the U-Boat type and the type of conning tower fitted to that U-Boat. See the Conning Tower section, to see which calibre deck gun is permitted for a given configuration.
Different types of ammunition are stowed for the deck gun at the beginning of each mission. These are:
AP - Armor Piercing
HE - High Explosive
SS - Star Shell
Ammo
Name AP HE SS Date Renown Cost
8.8cm SK C/35 40 160 40 January 1939 0
10.5cm SK C/32 40 60 20 January 1939 0
Flak Guns
Flak guns (Fliegerabwehrkanonen) are anti-aircraft guns. While their primary purpose is to fell enemy aircraft, they may also be used against very small surface targets (for example fishing trawlers). However, be warned that this is extremely ineffective and will require a lot of ammunition.
The type of Flak gun that may be fitted depends on the type of conning tower used. Each gun is classified as "light" or "heavy" and requires an appropriate mounting platform. See the Conning Tower section to see how many Flak guns of each type may be installed. Note that the 2cm FK C/38 Flakzwilling XXI may only be used on Type XXI U-Boats.
Flak guns may use one or two different types of ammunition:
AP - Armor Piercing
AA - Anti-Air
The quantity of ammunition stowed for each Flak gun type is indicated below.

Conning Towers
The different types of U-Boats may be fitted with different superstructures. Each conning tower may only fitted on the type of U-Boat indicated in the name. For example, a IID/2 tower may only be fitted on a Type II-D U-Boat. The choice of tower affects the number of deck gun and Flak installations that are fitted. Fitting a new tower may take up to two weeks.

Note that the VIIC/4 tower is the so called "U-Flak" configuration.
Also note that the Type XXI U-Boats may only use the Type XXI Flak guns as listed in the Flak Guns section.
