Hi, Llamaman! I was making also a Bolivian Armed Forces, but with a different approach: soviet, czech and chinese hardware. And the riverine navy (main force and base over the amazon basin instead over Lake Titicaca) with a mixed breed (american and russian) muscle. But certainly, your composition is much more realistic. Cheers.
Let your imagination run wild, reytuerto my good chap! I'm only doing this Bolivian stuff as part of a much larger South American AU. I'm keeping most countries largely similar as IRL but have some major changes planned for Chile, Brazil and Argentina.
But back to Bolivia. The FAB carried out a limited modernisation of its F-5 fleet in the late-90s. Dubbed the F-5M by Bolivian forces, it incorporated an Elettronica RWR on the fin and replaced the radar with APG-69. No other changes were made, save integration of the Matra R550 Magic II in place of the AIM-9D.
Although loved by its pilots, the ageing airframes and lack of J65 spares dictated the need for an A-4B replacement by 1998. Eighteen AMX attack aircraft were ordered from Brazil, being armed with M39 20mm cannons in the nose, bombs, rockets, Magic II missiles and a modified version of the Argentine Martin Pescador ASM equipped with IR guidance.
