The Red Arrows, the RAF's renowned aerobatic display team, are the subject of a defence investigation following allegations of what the service calls "unacceptable" behaviour.
The air force confirmed it has commissioned a "far-reaching" inquiry.
It comes amid a report from The Times detailing alleged accounts of misogyny, bullying and sexual harassment.
Defence minister James Heappey said "nobody is above" the values and standards of the Armed Forces.
He explained that some members have been removed from the display team for this season, while investigations are carried out.
The Armed Forces Minister told Forces News: "In the meantime, there is a very visible demonstration of the Royal Air Force's commitment to having the right culture for its people.
"That world-famous nine-plane formation that you see year in year out for the Red Arrows is currently only seven."
An RAF spokeswoman said: "The RAF has a zero-tolerance approach to unacceptable behaviour and takes action wherever wrongdoing is proven.
"Following allegations of unacceptable behaviour within the Red Arrows, the RAF commissioned a thorough and far-reaching investigation.
"We will not be commenting further on the individual circumstances of specific personnel moves, which have been made without prejudice and are the result of both personal and professional reasons."
The spokesperson continued that "allegations of Red Arrows pilots flying while intoxicated are unfounded" and that "all RAF pilots, in the Red Arrows or otherwise, are subject to strict regulations on alcohol consumption before conducting any flying".
"Safety remains paramount and any pilot found to have breached those regulations would simply not be permitted to fly, and would face disciplinary action."
