The Canadian Maritime Forces (MARCOM) currently operates 4 Victoria-class Diesel-Electric submarines. However, noting (like every other major power has already) the limitations and expense of maintaining diesel boats, it has undergone a new program of developing nuclear powered boats. It's estimated the first will be ready within the next 2 or 3 years.
During WW2 the US Navy built 126 submarines.
At the beginning of 1917 the German navy had 111 submarines. This was a large increase from 1916 when they had only 68.
There were no "Islanders" in the fight against German U- boats. This fight was carried by the Canadian Navy, Royal Navy and British , Canadian and US Air forces.

Nope - "HMS" stands for "Her Majesty's Ship" (or His, depending on the ruler of the moment), and U.S. submarines, like all U.S. Navy commissioned warships, use "USS", or "United States Ship". "HMS" is only used on ships or submarines within the realm of British Monarch (currently Queen Elizabeth II), primarily used by the British Royal Navy. It would also include navies from any country her realm, though they add their own country abbreviation within the acronym. Countries that include the acronym that have submarines are: Canada: Her Majesty's Canadian Ship (HMCS) - Royal Canadian Navy Australia: Her Majesty's Australian Ship (HMAS) - Royal Australian Navy
the military and navy use it for war and combat. Many submarines are made for launching missels and taking down ships and other subs.
