Raptor Vs Super Hornet

I'm a big supporter of warfare off-the shelf. Why not buy new models of old weapons and team them with new precision wepons which are being constantly produced, much faster than the Cold War style tanks, carriers, and fighters. Here's an article supporting my point:

*The Raptor program divided and distributed the work equally among three contractor teams, whereas the Super Hornet team was focused mostly on one.

*The Raptor program allowed concurrent technology development, whereas the Super Hornet managers sought incremental improvements to reduce risk.

*Super Hornet managers set up a larger management cash reserve for development problems than the Raptor leaders.
