Royal Air Force personnel will be allowed to grow beards for the first time in 101 years.
The change in the RAF facial hair policy will take effect from 1 September.
It will bring the RAF into line with the Royal Navy. The Army does not allow beards unless for religious or medical reasons. It has no plans to change, the Ministry of Defence said.
However, the beards will need to be "neatly-trimmed" and cover the entire jawline.
A spokesperson said:
"This change allows serving members of the RAF to wear a smart, neatly-trimmed, full set beard whilst maintaining high standards of appearance."
According to the RAF, this move will help broaden the recruitment pool, promote inclusivity and help retain skilled personnel.
