this is hard question... because i dont know nothing anout roland but...
OSA missile speed is aprox 2.5 mach and roland missile speed around 1.5 ! this is big point ! and maybe osa target calculator parameters is so faster than roland.. and the other side ... OSA SOC have longest detect range than roland at the end ... OSA armed with 6 missiles silo and roland i think that maximum overload is 4 missiles as mdore@ wrote : these 2 using one method ! CLOS !
It is not so complex.
Just maths.You have the range of both systems.
Well,why 1 OSA =~4 ROLANDs ?
I think your implication is that the range is 2x, and area 4x... but I'm not sure that ADA works quite like that... I'd assume more of a barrier than an areal coverage... so the effectiveness would be only a little better than 2x. For a point defense ~ it may even be less significant than that if the attacking aircraft can be engaged successfully before they reach weapon release point, and there is no difference against stand-off weapons that can be launched from outside the coverage of the larger system which are aimed at the 'protected' main target...
