Tanks were created for travel across battlefields
They prevented soldiers from being caught by barbed wire or gunfire. Cars were unsuitable because they could not get across the muddy ground.

The first-ever tank design was called 'Little Willie'
It weighed 18 tons and held a crew of two plus four gunners. It was the first completed tank in history but it never went out to war.

Design continued and a better tank was sent to the front line
The British Mark I tank was used in September 1916. It held ten men and reached speeds of almost four miles per hour.

Warships were ships with guns for fighting sea battles
Battleships were the largest warships and had very big guns. A Destroyer was a small, fast warship which fired guns and torpedoes.

Submarines were smaller but could destroy powerful warships
They sailed to places ordinary ships could not get to and stopped enemy ships from getting too close to Britain. The British Royal Navy had the world's largest submarine service when war broke out.

Bigger aircraft carried bombs to drop on troops
This was originally done by either the pilot or co-pilot dropping a bomb over the side of the plane.

German Zeppelin airships weighed 12 tonnes
Zeppelins carried around 2000 kilograms of bombs and carried out raids on England. However they were slow and eventually the British realised they could be shot and set on fire.

The Gotha bomber caused more damage than the Zeppelins
The Gotha had a 24 metre wingspan, the length of two buses. It could fly for 500 miles and carried 500 kilograms of bombs to drop on Britain.

The Giant bomber was even more powerful
It had a 42 metre wingspan, almost as wide as a football pitch. It could carry 2000 kilograms of bombs, four times as many as the Gotha. Not one Giant bomber was shot down during the war.

What inventions changed our world?

Cameras, telephones, microphones and radios are used by people today.

Until 1916 taking photographs on the front line was banned
This was in case it helped the enemy to find out secrets. After 1916 official photographers took pictures and films for the army. Some new cameras were small enough for personal use.

Cameras attached to planes were used to take pictures
Photographs allowed the army to spy on the Germans and make maps of the trenches and front line. With these maps they planned where and how to attack.
Image caption,
New microphones were used to identify enemies and dangers
The hot-wire microphone helped troops to work out where shells had been fired from. The hydrophone was used to hear sounds under water and locate U-boats (submarines).

Telephones picked up and sent Morse code between trenches
This allowed important messages to be delivered so soldiers across the front knew the plans for defence and attack. Wireless radio was also used, mainly at sea and by aircraft.
