On the Defensive side of the house: we need something like C-RAM, Pantsir, coprehensive Defense in Depth soutuions to provide rapid response to high speed projectiles and of course cost effective solutions that we can produce in house, even through ToT. Build more depth and dentity around our ADS systems, and more invesment in in EW and jammers for soft kills. Microwave-based drone air defense systems that'd use high-power microwave (HPM) technology to disable drones, effectively neutralizing them without resorting to physical destruction.
