The Birth of the Atlas Rocket Program

The Atlas rocket program started in the early days of the cold war. In 1945, the U.S. Armed Forces asked the aerospace industry to come up with ideas for long-range missiles. Convair, a top aerospace company, got a contract in 1946 to work on two main ideas: a sub-sonic jet system and a supersonic rocket design.

Karel "Charlie" Bossart, a famous engineer, led Convair's work on the Atlas rocket. Bossart's team created a new idea called the "pressure stabilized hull." This made the rocket lighter and more efficient. This innovation was key to the Atlas program's success.

Cold War Origins

In 1955, President Eisenhower made the Atlas rocket a top priority for national security. This was two years after Convair got a new contract to focus on the rocket idea.

Year	Event
1945	U.S. Armed Forces request long-range missile concepts
1946	Convair granted contract to develop Atlas rocket
1955	Atlas program designated top priority for national security

Innovative Engineering Solutions

The first Atlas rockets were 74 feet long and 10 feet wide. They could go 600 miles without a special section and only 60 miles with a warhead. Despite these limits, the pressure stabilized hull design by Bossart and his team at Convair was a big step forward for the Atlas program.

"The pressure stabilized hull was a game-changer for the Atlas rocket. It allowed us to create a lighter, more efficient vehicle that would eventually open the door to space exploration." - Karel "Charlie" Bossart

From Weapon to Space Explorer

The Atlas rocket's growth caught NASA's eye for space travel. The Atlas B rocket could reach orbit, perfect for launching satellites and other space payloads.
