Ah, so they consider the Bushmaster for LAND 19 Phase 7 but Raytheon and Kongsberg were able to integrate Enhanced NASAMS onto the lighter Hawkei instead. Meanwhile, Kongsberg and Thales are aiming this StrikeMaster - Block 1A NSM on Bushmaster ute - for Land 4100 Phase 2 with the connection between the two being the FDC.
Presumably, the NSM launch canisters were simply too big/heavy for the Hawkei?
