Did U-boats have to surface to fire?

And it must have done so on the surface of the water, where it was able to travel at a faster speed than the ships it pursued. By approaching from astern, where the lookouts rarely checked, the U-boat would be able to slip inside the convoy undetected, fire at close range, then submerge in order to get away.

Why did U-boats have to surface to fire torpedoes?

U-Boat Surfaced Torpedo Attacks. The greatest advantage of a surfaced attack is speed. A surfaced U-boat is highly maneuverable and faster than many escorts. The U-boat can use its speed to run ahead of the convoy in order to setup an attack position.

Why do U-boats have to surface?

One U-boat would shadow a convoy and summon others by radio, and then the group would attack, generally on the surface at night. These tactics succeeded until radar came to the aid of the escorts and until convoys could be given continuous sea and air escort all the way across the Atlantic in both directions.

How were torpedoes fired from U-boats?

a) After taking the position up, the U-Boat cruises slowly on a course opposite the target's course. When the U-Boat gets closer to the target, it turns 90º and launches torpedoes when the target appears in the crosshairs of the periscope, which was set to the deflection angle determined by the torpedo director.

Did U-boats travel on the surface?

While U-boats were faster on the surface than submerged, the opposite is generally true of modern submarines. The most common U-boat attack during the early years of the war was conducted on the surface and at night.
