I would imagine that Harvest Hawk went into the same "rejected" tray as arming the Nimrod at Basra. Couldn't possibly do it as it would risk future funding for FJ if we could prove, albeit in a permissive air environment, that it would be cheaper and more effective to have large war-loaded ac loitering over contacts for several hours than keeping multiple flights of FJ on the go with associated tanker support...
Perhaps just a bit too cynical...?
