What weapon platforms can we make out of the weapon platforms that we already have? I have a few in mind: Astra-1 can evolve into a VSHORAD SAM or MANPADS with 10-15km range. Astra-2 can evolve into a QR-SRSAM with 20-25km range which can be used for Army AD, Naval CIWS or IAF Point Defence systems. AAD can evolve into our home grown MR-SAM in the 40-60km range. ("Ashwin" probably planned) PDV can evolve into our own ER-SAM with 150+km range. Pragati can evolve into MR coastal defence system with the incorporation of seekers and control surfaces with 150km range. Short range Nirbhay with transonic propulsion can give us cheap long range coastal defence system with 500km range. Same could be used as a land attack cruise missile to bridge the gap between Brahmos and Nirbhay. (LFRJ-LRCM?) Pinaka in a 122mm version with 20-30km range and 40 tube launcher which can be mounted on tracked/wheeled FICV and be part of Mechanized Infantry.
