The system was known as the Escorted Convoy System, and was used to great effect by the Allies to counter the early successes of the U-boat fleet. The convoy system, in concert with advances in ASW techniques and long-range bomber support, eventually pushed U-boat losses to over 70% for the Germans.
It was necessary because then every convoy could be escorted by destroyers to protect them from German U-boats. The destroyers were armed with sonar and depth charges to find and destroy German Subs.
At the beginning of 1917 the German navy had 111 submarines. This was a large increase from 1916 when they had only 68.
The role of submarines during the second world war was primarily the destruction of enemy commerce, and occasionally heavy naval units such as battleships, cruisers, and aircraft carriers. Since the battle of the atlantic was fought primarily against German Submarines which were targeting Allied merchant vessels, there would have been very little point to using submarines.
They had no weapons.
The dreadnaughts and the cruisers were held well back to insure a counter strike ability. It was the destroyers (DD), destroyer escorts (DE) and motor torpedo boats (MTB) that provided the front line defense against a breakout by the German Fleet.
This would be a convoy. They were limited to the speed of the slowest ship. They used a zig zag pattern to make it difficult for the submarines to get a firing solution against them.
Destroyers, aircraft, and the convoy system.
Early in the war, merchant ships carrying supplies to both Russia and Britain were targeted heavily by German U-Boats(submarines). Since there were not enough destroyers and destroyer escorts to protect each individual ship, convoys were formed. In these convoys, merchant ships were grouped together and protected by a small number of escort vessels
Unterseeboot, known as 'U Boats'
A group of German submarines is called a Wolfpak.

Merchant ships and escorts formed a convoy to improve security on the high seas.
With the concentrated use of anti-submarine ships and aircraft.
