The Monitor (representing the North), and the Merrimack (representing the South) battled on March 8, 1862. Although there was no winner, the Monitor was a better ship. This was the first time that ships were fitted with armour for battle. The battle between the Monitor and the Merrimack would cause the building of more ships for battles and wars in the future.
Convoys were used to destroy any U-boats that were in their way.
Ships and navigation improved in the 1400 and 1500's. Ships got rudders and moveable sails. With these they were able to move better and catch winds rather than just sitting waiting for wind. Tools for navigation improved as well. The astrolabe was invented to allow the use of longitude and latitude settings. Ships were also bigger.
Aircraft yes. Ships no.

Unlike later ships of the Age of Sail, Viking longboats had many oars, as did the earlier ships of the Roman Empire. (see the drawing in the link below)
The ships were powered by oars or by the wind, and had one large, square sail, most probably made from wool. leather strips criss-crossed the wool to keep its shape when it was wet. Viking ships also had oars. A steering oar or 'steerboard' was used to steer the ships. it was fastened to the right-hand side of the ship at the stern (back)
Viking ships were 15 to 35 meters long.

A longship was a ship the Vikings used to raid villages. The ships were long and narrow and were designed for speed and war. The ships were about 23 metres long, 5 metres wide and 12 metres high.
The sail was invented long ago and provided a way to harness the wind to power ships. Gas turbine engines came along in modern times and is used today to power ships.
Because these ships were used mostly in battles.
