British U class submarine
Overview
 
The British U class submarines (officially "War Emergency 1940 and 1941 programmes, short hull ") were a class of 49 small submarines built just before and during the Second World War. The class is sometimes known as the Undine class, after the first submarine built.
These small submarines, of around 630 tons, were originally intended as unarmed training vessels to replace the ageing H class, to be used as practice targets in anti-submarine training exercises.

s. Apart from Undine and Unity, all boats were also equipped with a three-inch (76 mm) gun, although they lacked a hatch for the gun crew, who had instead to use the main conning tower hatch.

). The external tubes were dropped from later vessels because they generated a large bow wave
Bow wave
A bow wave is the wave that forms at the bow of a ship when it moves through the water. As the bow wave spreads out, it defines the outer limits of a ship's wake. A large bow wave slows the ship down, poses a risk to smaller boats, and in a harbor can cause damage to shore facilities and moored ships...

Unity was the first British submarine to have a propeller designed for best submerged performance rather than surfaced performance. It was thought this might reduce propeller noise.

Group two boats

The second group of the U-class consisted of twelve submarines, of a similar design to the original three, but most were modified to improve depth keeping. This group included a number of submarines that would go on to become particularly famous. Urchin was transferred to the Polish Navy

In her 16 month operational career in the Mediterranean, before she was sunk in April 1942, Upholder carried out 24 patrols and sank around 119,000 tons of Axis ships – 3 U-boats, one destroyer, 15 transport ships and possibly a cruiser and a destroyer. Losses in this group were high, however. Only three out of the twelve survived the war.

Group three boats

These formed the largest group of 'U' class submarines, comprising 34 vessels ordered in three batches. Losses continued to be high. In June 1940 the decision was taken, in view of the anticipated high number of submarines to be ordered, to drop the practice of naming submarines, so these vessels were initially labelled P.31 to P.39, P.41 to P.49, etc, instead of receiving names. At the end of 1942 Churchill personally ordered that all submarines were to receive names, but eight ships were lost whilst in service with the Royal Navy, before they could have their names officially assigned. In addition, a number were assigned to allied navies, both before and after the war. One assigned to the Norwegian navy, HNoMS Uredd, was also lost after hitting a mine. The last surviving U-class boats were scrapped in the 1950s.
