The police helicopter base in Sheffield is to be axed next year.
National Police Air Service bosses have confirmed plans to close 10 bases to save cash.
Since April 2013 South Yorkshire has been served by a helicopter based at Sheffield for 10 hours a day.
For the remaining 14 hours a day the county is served by aircraft from neighbouring NPAS bases in West Yorkshire, Humberside and Derbyshire.
The Sheffield base is due to close on February 1, 2016.
Temporary Chief Superintendent Adrian Moran, of South Yorkshire Police, said: “We have only just been made aware of the decision taken by the NPAS strategic board.
“Their plan to close the Sheffield base in February 2016 gives us 12 months to work closely with NPAS to ensure that they maintain an effective air service for South Yorkshire.”
