Thanks once again for your valide input Greg (GTX)!
I like the SARH / IR combo, very sensible, very Soviet.
But alas, the information we've sorted in the past in relation to the AIM-9C SARH, with the Vought F-8 Crusader, clearly indicated 'unreliability'. On top of that, as you'll see and appreciate in the backstory of the ship this missile/launcher is to be placed on, the Chaparral/Sea Chaparall doesn't have the necessary range envelop, which is needed; again hence the Sea Sparrow preference mate.
Interesting that you should post the 4-cell and-based launcher Greg, I personally like its light-weight nature and incorporated sensors, in terms of its lrospect of ndividuality of operation!! A marinzed derivative might be workable!!
[I even found a 6-cell derivative]
Regarding Sea Dart box launchers, I have to excuse it, as Sea Dart is not operated by the RAN in my 'Alternative ADF ORBAT'; and the associated Sea Dart radar/fire-control systems are way to big, heavy and complex for the ship it's intended to arm.
M.A.D
