Consider this, the engine is the most maintenance demanding piece of equipment on a jet. Single-engine will cut the biggest maintenance item on your cost list by about 50%.
The Mirage 2000 production line has been closed or will be closed soon. So if you want something new from France, you have to cough up for the Rafale.
The fact that the MIIIs are so old is exactly why an interim purchase is likely. New ones have more lead-time. Russia delivers fast, true, but you'll still to bridge a gap of at least 5 years before they are fully operational. However, the Skyhawk force may be deemed sufficient for that?
True, the Chile contract (they bought 18 though, count another 4 single and 2 duos) is my inspiration behind my last post. However I don't think it will happen until maybe they get some US surplus or new F-16s first. Just because they are old and high-houred, they are only interesting to existing F-16 operators who need an interim solution until they can buy more new ones, or just need more two-seaters (Jordan). The problem with a non-F-16 operator buying them before the arrival of new F-16s with US support, is that older aircraft require more maintenance/engineering and spare parts support, so they probably will be too costly if you don't already have your F-16 logistics in place.
If I recall it correctly, Chile paid $180 Million for 18 jets, upgraded to MLU standard 3 and/or 4, including engineering training/support. They are Block 15s built between 1982-1988, updated in 1997-2003 to Block 20 MLU standard, and were M2 software standard, but I believe the US DOD requirement was to upgrade them to the latest MLU status before delivery, I think that brought them to M3 status as M4 consists of software updates for equipment not used by Chile? HMD, Link-16 for example? At least a $7.5 million contract with LM was needed before the sale could continue. And the US required the RNLAF to overhaul them before delivery. They have about 3,000 hours per airframe. Despite, the houred airframes, I still think it's pretty cheap. I actually haven't seen many cheaper second-hand jet deals with upgrade/overhaul included at this capability level.
But enough about F-16s and MiG-29s, latest news in the aviation press seem to suggest ex-AdlA Mirage 2000Cs again.
