A RAF fighter squadron in Lincolnshire is disbanding several months earlier than planned.
The Jaguar has been flying with the RAF for 33 years
Number 6 squadron at RAF Coningsby will be taken out of operational service early next month.
The closure marks the end of the Jaguar fighter's career. Many of the 300 staff will move to the Eurofighter squadron.
The commanding officer called an emergency meeting at the base to inform the staff of the Ministry of Defence announcement.
The closure of the squadron has been expected for some time as the Jaguars are being replaced by a new squadron of Eurofighters.
The Number 6 squadron is made up of 10 Jaguars and about 150 personnel including pilots, engineers and ground crew.
The MOD said no redundancies were expected with most of the current squadron moving over to work with the new Eurofighters.
Any other personnel would be moved to elsewhere within the RAF.
Former commander Jerry Connolly said it will still be a turbulent time for staff.
"It may bring a little bit of anxiety and instability for some people who thought they would be here until September. It will cause a bit of disruption.
"But these things happen in the military and they are handled and dealt with."
The Jaguars have been flying with the RAF for the more than 30 years.
A flypast event is expected to take place at the base on 25 May.
