Seafire isn't a spitfire. It has Sea instead of spit so it doesn't count.

The spitfire is an RAF aircraft, the seafire is in the Fleet Air Arm.
Compleeeeeeetely different aircraft.

Ok you got me, i was trying to make the spit varients look smaller.
But it can't be helped to have so many different variations of the spitfire. It served as the Uk's (and commonwealth) frontline fighter from the outbreak (well there were more hurri's at the outbreak) of the war until the end and it was constantly improved upon as a consequence.
Soooooo...add more spitfires!:D
