"Third, like I said, not modern air force is ignoring IRST."

Eurofighter and Superhornet first flew in mid 90's. Eurofighter has been shipped with PIRATE IRST since 2007. At the same time dudes started thinking about equipping Super Hornet with short range IRST. That option will be available some time this year. Maybe, or it will be delayed by two years.

U.S. is not ignoring IR spectrum completely. But it's pretty low priority compared to other players.
