Stunner is actually triple pulse missile with no warhead. It's direct hit to kill. Thus even in that small size, it packs quite a punch. Astra 2 won't be able to match it, IMO.We already got that with the S-400.
Depends on the booster. I'd actually say the Astra Mk2 will be superior to Barak 8. We see the same thing with David's Sling, the missile is smaller than the AMRAAM and uses the MRSAM's radar.
You can see both side by side here.
Our overall SAM and BMD development have very closely followed Israel's. Both of us are using target-specific interceptors. So they have Iron Dome against rockets and artillery, SPYDER and MRSAM/LRSAM against air targets or as CIWS, David's Sling as long range AD and then Arrow series as BMD. We have no need for Iron Dome, but we use SPYDER, Akash and MRSAM for local defense and plan to use XRSAM for wide area defense.
With that said, I won't be surprised if we end up using David's Sling too, but you can see that it's simply better for us to use our own missile instead.
Yeah, but there's no reason why it cannot be XRSAM, Barak 8 has a very similar design after all.
