Emergence of submarines and military aircraft – fighter and bomber planes.

1. First introduced in 1915, submarines were used a lot during WW1 and 2; U-boats were German submarines that were very effective, able to sink five British cruisers within 10 weeks and were responsible for the loss of 11 million tonnes of allied shipping during the War. Submarine warfare developed significantly during WW2, with the Allies having to adapt to Germany's effective strategies; the Germans used wolf-pack tactics (attacking in big groups) and the U-boats remained successful during early WW2, until.
2. WW1 introduced the first time that aircraft had been used on a large scale. Germany employed Zeppelins for strategic raids over England and the Eastern Front. Aircraft was even more decisive in WW2, with the introduction of Blitzkrieg tactics during the Invasion of Poland and Battle of France, where aircraft worked as flying artillery to quickly disrupt defensive formations.
