The German Navy did use its surface ships, but the U-boats were able to attack without being seen.
The surface navy is the surface ships that make up a strong portion of the navy.
The Navy it selves refuse to give vessels to the German Army. To ensure this would not happen, the Danish navy desided to sink their own ships while in habor. A battle broke out with german soldiers, however the opperation was a success and no ships where granted to the enemy of Denmark
England had the most powerful surface fleet of ships, while Germany had the most powerful submarine fleet. England's surface fleet won out over German submarines.
Because the German navy was not a strong navy, they had to rely on submarines to attack merchant ships...Guerre de Course (Commerce Raiding).
I think they were all U boats. U followed by the number. I don't think they had names, not official ones like surface ships. ADDED: They were just numbered, as you say. I believe the Federal German Navy still uses the same system ('U-boat' is only the Anglicised abbreviation for 'Untersee Boot', which means... 'undersea boat'). The Royal Navy names its submarines as it does for surface ships, but all RN vessels are also given fleet numbers.
Your teacher is probably referring to the "Convoy System" that was developed by the British Royal Navy & used by the Allies. It meant that merchant ships with the same cruising speeds traveled together in a group or "convoy". The group may be escorted by Navy warships that were capable of protecting the merchants from German U-boats, Q-ships, or surface raiders. Ships that were very slow, or fast would not travel in a convoy.
i think it has 5 navy ships.
Of course, navy aircraft are military aircraft.
Ships of the Royal Navy was created in 1969.
I presume you mean armed ships disguised to look harmless. Such ships used by the British in World War I were known as Q ships. Those used by the German Navy in World War II were known as "Auxiliary cruisers" -- I think the German word is "Hilfskreuzer".
A "navy" is the branch of a nation's armed forces principally used for naval and amphibious warfare ie. travelling and fighting on water in a fleet of surface or underwater vessels/ships.
No, no army has more ships than its navy.
