Military officials unveiled a plan to split 12 overdue and over-budget fighter-jet squadrons between Marine Corps Air Station Miramar and a base in Arizona.

The announcement came at a public meeting Tuesday night at the Mira Mesa Library, which was attended by military representatives and residents.

Five potential alternatives within the plan would designate as few as two or as many as 10 F-35 Joint Strike Fighter squadrons to Miramar, starting in 2012. Whatever was left of the 12 squadrons would then go to Marine Corps Air Station Yuma in Arizona.

The number of aircraft in a squadron varies. At Miramar, the new F-35s would replace six squadrons of F/A-18 Hornets, which equals about 90 aircraft.

Some residents expressed concerns about safety, following the recent jet crash in University City.  The F-35 is a single engine jet and some people felt it might still be too experimental. 

Others had more every day concerns, like noise and air pollution.  An environmental impact report still needs to be completed. 

The Marine Corps will accept public comment through February 17th.
