Alao, in case of the stinger, ypu talk about compatability issies woth a myriad of other systems, oldy really old and new. After all, it can be fired as aanpad, from air vehicles, ground vehicles and from sea. The existing design is guaranteed to work with all platforms it can currently be fired from. Changing the design means loosing that guarantee, and would require a tremendous amount of testing. So, there is a kernel of truth in saying it will expensive to recreate production tech to build current spec stingers. Also true that this kernel of truth is great opportunity to get more funding.
