The U.S. Air Force currently has the shortest basic training, lasting 7.5 weeks.
Here's a breakdown of basic training lengths across different branches:
- U.S. Air Force: 7.5 weeks
- U.S. Space Force: Personnel are drawn from the Air Force and have already completed Air Force BMT. Therefore, they don't have their own separate basic training.
It's important to note that these lengths can sometimes fluctuate slightly based on specific circumstances or training requirements.
