Royal Air Force
In short
The Royal Air Force (RAF) is the air and space warfare force of the United Kingdom, its overseas territories, and Crown Dependencies.
In plain words
It is the part of the British military that handles fighting in the air and in space. It was created in 1918 by joining together the army's air unit and the navy's air unit.
A simple example
An RAF pilot might fly a Typhoon fighter jet to patrol British airspace or deliver supplies to remote areas.
Why it matters
It protects the United Kingdom from aerial threats and supports global military operations. It also plays a key role in search and rescue missions.
Easy to mix up
Do not confuse it with the Royal Navy, which focuses on sea warfare, or the British Army, which focuses on land warfare.
