Sorry - I was talking fighter squadrons - my mistake
Delivery of the final Tranche 3 aircraft brings to an end a production run of 160 Typhoons for the RAF that began in 2003. The RAF fields eight Typhoon units with 1 (Fighter), 2 (Army Cooperation), 6, and 9 (Bomber) squadrons based at RAF Lossiemouth in Scotland; and 3 (Fighter), 11 (Fighter), and 12 (Bomber) squadrons based at RAF Coningsby in England. There is also a permanent detachment (1435 Flight) located on the Falkland Island
With the F-35 only 617 is stood up and in action and it has about 6 -8 aircraft - a pretty small squadron IMHO and the rate of new deliveries is ... "measured"
