I don't know about sank, but the types of aircraft used in detection of the U boats in the Atlantic include: Liberator, Catalina, Sunderland, Walrus, Hudson, Anson & Beaufighter.

During World War I, German submarines were primarily referred to as "U-boats," short for "Unterseeboot," which translates to "undersea boat." The most notable classes of U-boats included the U-boat Type U-1, U-boot Type U-19, and the larger U-boat Type U-35. These submarines were instrumental in Germany's naval strategy, particularly in unrestricted submarine warfare, targeting Allied shipping to disrupt supply lines.
Not anymore. In both world wars submarines were equipped with anti-aircraft weapons for defending themselves while surfaced, but they made the subs slower while submerged, and enemy aircraft usually stayed out of their range while calling in a destroyer by radio. After World War 2 submarines became streamlined to improve their speed, and their AA guns were removed. The prevailing school of thought is that a submarine has a better chance of survival underwater than trying to fight on the surface. The British Navy experimented with a missile launched from submarines to shoot down aircraft, but even still the aircraft holds most of the advantages, and the submarine is probably more apt to survive by hiding under the waves.
The sinking of the Lusitania and German submarines in American waters
The Battle of the Atlantic was ongoing throughout most of World War II. It referred to the campaign by German submarines to attack and sink Allied shipping bringing supplies from the US and Canada to Britain to keep the country fighting and to stop the people from starving.
What is called the Battle of the Bulge in the United States was part of the German Ardennes Offensive of 1944. It was a last-gasp effort by the German Army to stave off defeat in the Western European Theater - its primary goal was the Belgian city of Antwerp, the major port from which Allied supplies were flooding onto the continent. It was hoped by that re-taking Antwerp, the Allied forces in Western Europe could be contained long enough to possibly negotiate a peace (or, alternately, allow for more time for Hitler's Superweapons (the various V-rockets and jet aircraft) to play a significant role). While initially successful, mostly due to failures of Allied tactical planners to appreciate that a major German offensive was in the making, the German attack ultimately stalled due to lack of fuel. As the weather cleared a week or so after the battle began, Allied tactical aircraft ravaged stalled German units, and prevented the furthest penetrating German units from resupplying. In the end, the offensive was a German failure, and a strategic Allied victory, as the German army lost most of its remaining quality units, and the Luftwaffe effectively ceased to exist. The Battle of the Bulge was the last significant German offensive of WW2.
USA has the most nuclear submarines
Depends on what it is armed with, if it is an f15, it would most definitely be a real threat to an enemy aircraft, but if it was a nuclear armed b52, it would be deadly to whole nations. Probably the most deadly would be the navy's nuclear armed submarines
Most warships, including submarines were recycled (melted down/scrapped) after the war.
During World War 2 the major supply line of the Allies was the supply line created by cargo ships crossing the Atlantic Ocean with war supplies headed to England. The most common threat was from German submarines.
The Navy conducts most of its missions at sea, utilizing its fleet of ships, submarines, and aircraft to operate in international waters and coastal regions. This allows for a strategic presence in key areas around the world, including chokepoints and maritime trade routes. Additionally, the Navy engages in joint operations with allied forces and often participates in humanitarian missions and disaster relief efforts.
Mostly any of the Allied forces fought with the French. Often if allied aircraft crashed in a German occupied land, the French forces known as the "Maquis" would assist them in escape, so the French were accepted as a valuable ally to most all the "good guys" UK forces seemed to most often work with Frech forces.
