Someone should tell them SLAM uses one style of wing. I wonder if someone saw a SLAM / SLAM-ER comparison drawing and slavishly copied it when making the mock-up.
I'm curious, why does it need another set of dorsal fin. Some form of "fix" for aerodynamics imbalance or maybe an attempt to allow skid to turn steering ?
So the missile could use rapid response skid steering on terminal while for cruise it will use more efficient Bank To Turn to assure best possible airflow for the inlet.
Faired antennas ?
