Nightfighter in its Mk.I and II (Merlin-powered) versions, fighter-bomber and anti-shipping strike fighter in later years - so no F3.

I am unable to link to another thread on this subject where I posted a picture from the pilots seat. F3 is just about a must when you look back. Also take into consideration that this aircraft will most likely be used in all arenas if we get a couple of models so how will you know if some one is behind you?
You can't see back at all. For your purpose based off your post it maybe valid in scenarios but it won't last 2 minutes in the main arena with out f3 mode.
