Canadians in the Air and Sea

• • At first unarmed airplanes were used just to locate the enemy positions
  • Sometimes they would throw bricks or links of rusty chain at the propellers of opposing planes
  • Germany made gas filled balloons called Zeppelins
• germans - Also developed a superior plane called the Fokker, armed with a machine gun with a firing mechanism timed so the bullets didn’t hit their own propeller

  The Brits copied it and named it the Royal Aircraft Factory S.E.S
• • The Fokker triplanes had 3 wings and the top speed was 140km/h. 
• Dogfight: an Aerial battle between fighter aircrafts in close combat
• • Billy Bishop was considered Canada’s finest ace since he shot down 72 planes during WW1
  • Awarded the Victoria Cross
• • Manfred von Richthofen also known as the Red Baron was the German ace, he shot down 80 enemy planes
• Ace: a pilot who shot down five enemy planes
• • The German submarines or U-boats had been used since the start of the war in 1914
  • Germany’s most deadly weapon
• • In early May 1915 the British luxury liner, Lusitania, was crossing the Atlantic Ocean. The Unarmored ship carried 1962 passengers, sunk by a German torpedo. Approximately 1201 passengers drowned, sinking it upset the United States because half of the passengers were American
• • Prompted the Allied nations to develop sonar equipment to pick up the sound of subs’ engines underwater
  • They used underwater echoes to find the position of the submarines the dropped depth charges (hedgehogs) to destroy them
  • Oldest anti-submarine weapons and the “hedgehog” threw 24 small projectiles several hundred feet, exploding on contact
  • Only partially effective because in the end 274 German submarines sunk 6596 boats
