Also, in line with realistic modelling aims GW has reduced the
damage potential of the deck guns which is explained below.

Armor piercing rounds have been removed from the GW mod as our
research indicates that typically the only type of round
carried by the U-boats was "HE" or "High-Explosive."

Furthermore, the crew when ordered to the deck gun takes time
to load the first shell... instead of the instant BANG you got
in stock SH3.

A little compromise we made too was including 20 starshell
lumination rounds per boat and extended the range of the
starshell closer to the range of a standard HE round. In real
life you can shoot one just as far as the other... I've done
it.

With all of the discussion about AP rounds in Uboats, here's something I found at Uboataces.com under deck gun attacks:

Although intended primarily as a defensive weapon, the deck gun however could be used against stragglers and unescorted merchants, and some ships, particularly tankers could be sunk at leisure, even in daylight. It was also useful in conserving the limited torpedo supply and to finish off the kill of a ship crippled by a torpedo.

A small watertight locker stowed near the gun held a few more rounds ready for use, providing an advantage during the first few vital seconds of engagements. This also meant that crash dives took longer than usual, as the gun had to be secured and crew rushed below deck. There were no range finders, so engagements had to be done at close range. With an experienced crew, the rate of fire was between 15 to 18 rounds per minute. Three types of ammunition could be fired; armor piercing, high explosive and star burst (flare).

An attack could be aimed at the target’s bridge, waterline or weapon systems. Attacking the bridge will hinder the victim’s steering ability, while attacking at the hull’s waterline would quickly sink the ship. Attacking the weapon’s systems will hinder the victim’s ability to fire back, but it takes just one unlucky shell to penetrate the U-boat’s hull which will make diving impossible. Armor piercing shells are better suited to hull attacks, while high explosive could be used against other targets.
