I agree the $24k doesn't sound right, Aussies costed it at $21k @ 200 hrs per year for 30 years.
USA has a higher SDD cost, is that included in cost per flight hour which may explain why the usaf is more, as costed by USAF and CAPE
NOTE.. it isn't a LM or JPO price
he did clarify that the $85ish mil was a then price and $75m in todays dollars and yes it includes an engine
Bogdan confirmed figures from Lockheed Martin that a device that Netherlands is possible to buy in 2020 will cost. Approximately $ 85 million. That's about 75 million dollars if you convert to this day, he added. "That is the maximum that I would pay for it. Aircraft" He expects the cost of the unit will go even further down.
