How expensive was it? As listed on PDF page #131 the average cost of a AIM-9X Block 1 AUR (1289 AUR produced) in 2017 dollars was ~$282,000 across all produced lots + excised options for the USN between ~2003~2017.
The Block II (“-9-2”) are ~400k per AUR, and “Block II+”(“-9-3”) had not entered full scale production so were not yet spun up at the time.
Don’t read French; but (source) claims that 840 (370 EM + 470 IR) AUR were ?produced / planned? for 1,815,000,000 Euro; so 1,815,000,000/840 = 2,160,714 2005 Euro’s, the exchange rate was 1.19 USD to 1 Euro ( 0.84 Euro cents to a USD), so 2005 USD it’s 1,814,999 per AUR, account for inflation from 2005~2017 it’s 2,277,995 2017 USD.
So a unit cost of between ~2.3 and 1.8 Million 2017 USD (2,277,995 ~ $1,795,337, depending on the exchange rate); so it was somewhere between 6 & 7 times more expensive per AUR (sort of).
"Le coût total de ce programme est évalué à 1,815 milliard d’euros, en
diminution en raison des ajustements intervenus ; le projet de loi de finances pour
2005 ouvre pour ce programme 58,87 millions d’euros en crédits de paiement et
138,3 millions d’euros en autorisations de programme. "

I wouldn’t exactly say that that’s close
