A very expensive and heavy scout , for sure in the AH-64A/D/E airframe.
However a couple of things come to mind, what have other countries such as Australia and Japan done in the last decade or so? The Tiger being a dedicated AH has taken over the recon / observation role of the Bell 206B Kiowa in the former while the two seat OH-1 in. JGSDF has replaced the OH-6J (I'm not counting the AH-64J slowly replacing the AH-1J) ....
Must confess, haven't read into the plans of replacing the Kiowa fleet but wonder if Boeing will tailor / modify the Apache / Longbow airframe to the scout role, make it lighter, more nimble, agile, flexible platform, perhaps ( and no I wasn't talking about removing the Hellfires)
Cheers
