Hello again after a little break
I have learned about what SAPAN is and the actual name of the quadpack missile
First off, SAPAN is a programme to develop naval air defence missiles (Covers anything for MİDLAS you can think of)
Our awaited missile isn't named HİSAR-D Block 2 or something similar, it is named
G/M-1 and the difference isn't only in the quadpack capability. It will also have an AESA seeker and new guidance algorithms to more reliably counter supersonic and low-observable anti-ship missiles.
