Technologies that helped the Allies win World War 2

New Technologies in World War 2

The ‘joystick’ helped control airplanes in battle

The new radar device was used to detect enemy planes ahead of time

Searchlights were used for the first time to guide and search for planes at night

New larger machine guns were developed to fire at airplanes.

The German ‘doodlebug’ missile was a long-range weapon

Germany developed the Panzer-a SUPER heavy tank!

World War II planes were much improved over WWI models.

Large ships that carried aircraft were used

Lots and lots of airplanes!!!!

BIG bomber planes were used to drop bombs in enemy targets

NOTICE THE OPEN HATCH?

This was a ‘fragmentation’ bomb and would splinter and cause huge damage to enemy

troops

New boats would carry men from the ships to the shore

These new water and land vehicles ‘tanks’ could travel across both with

ease!

The Japanese military used poison gases on the Chinese during World

War 2! Thousands died!

Because so many were fearful of poison gas from the first world war, both sides refused to use it

against enemy troops. They knew if they used it, it would be used back on them.

The world’s first computers were developed in World War 2.

They were huge!

Some technologies were not new. Here a Japanese soldier is about to behead an

Australian prisoner of war with a sword!

The most dangerous technology in World War 2 was a new

unbelievable new bomb being developed.

The ‘atom’ bomb was being worked on by scientists on both sides. Whoever got it perfected first had a huge advantage.

Atom bombs create a HUGE amount of energy when they

explode! • Atom bombs split the basic unit of matter-

the atom.

Albert Einstein was a famous scientist from Germany who happened to be a Jew who

escaped to the U.S.

Einstein met with Roosevelt and told him the Germans were working on an

atom bomb!

The U.S. hurried to get top scientists to develop an atom

bomb!The U.S. super SECRET effort to build the

atom bomb was code-named the ‘Manhattan Project’.

They blew the first one up in New Mexico in the middle of the desert.

The atom bomb exploding in the desert where no one lived! It was a success! The United States now had the world’s most powerful weapon!

The U.S. sent secret messages in American Navajo Indian language. Why

this language? (p. 357)

A WOL-LA-CHEE =ANT

A BE-LA-SANA =APPLE

A TSE-NILL=AXE

NE-ZHONI= PRETTY

GLOE-IH =WEASEL

The Navajo Indian code talkers helped America win the war!
