Your chart
in this case well done !
You confirm ? 12 F-35B for a Sqn coz in theory Typhoons Sqns front line ofc have 13 whose 1 two-seater in fact 11 to 15 and Tornados 16 in fact 12 i have
But a little curious different number for F-35B maybe in relation with 48 ordered... also USN going to use Sqns with 10 C then Super Hornets units have 12 but surely for price reason.
The preferred sqn size for UK F-35Bs has been set at 12 for over ten years now. There are no twin seat Lightnings, training will be conducted on simulators,- both QECs will have two simulators aboard ship linked to a flyco simulator so sorties can be practiced before taking off. Similarly there will be simulators at the Lightning's home base at RAF Marham to compensate for the lack of two-seaters. 12 aircraft sqns have been calculated as necessary to provide a round the clock two aircraft CAP for air defence as well as a standby small anti ship strike package and one or two aircraft in maintenance at any given time. As a basic force protection and limited strike capability a single sqn of 12 packs a hefty punch, which is why most Naval Harrier operators go with it as the model.
In the Sea Harrier days the RN originally went with 5 aircraft sqns (two CAPs alternating between high readiness deck alert and 30 minute readiness as back up and a fifth aircraft as a spare). Five aircraft was seen as the minimum needed to provide a credible 'Hack the Shad' capability (interception of a shadowing Russian Bomber in the North Atlantic) without arousing the suspicion of the RAF that the RN was getting back into the carrier game properly, but the plan was always to boost the numbers of SHARs in the frontline sqns in time of war using pilots crews and airframes from the headquarters sqn (899NAS), which always had 12 aircraft on strength and more pilots than planes (the frontline sqns had five aircraft each but about 8 or pilots so airframes could spend more time in the air after a given pilot had reached his maximum hours for the day). This plan was carried out in 82 when 899 gave up seven aircraft and pilots to 800NAS aboard Hermes and three more to 801 aboard Invincible. The remaining four aircraft plus four more drawn from storage were used to stand up a third frontline sqn, 809NAS which flew down to the Task Force a few weeks later and on arrival reinforced the other two sqns, four each to 800 and 801. After the war plans were announced to increase sqn size in peacetime to 8 aircraft each but this was done incrementally over a couple of years. Other Harrier operators such as Spain and Italy went with the twelve aircraft sqn size from the start to get maximum 'bang for buck', mainly because they didn't have historic opposition from their Air Force to deal with.
