Other, more conventional competitors in the Army's Armed Scout requirement
** EADS is offering a AAS-72X+ for the same competition. Build in Columbus, Mississippi and backed by LM
** A re-engined Bell OH-58F Block II
** A stretched Boeing AH-6S Little Bird
The OH-68F Block would offer the best commonality with the current Kiowa's and maybe be the cheapest (?)
EADS US Columbus shocked the DoD/Army by delivering the UH-72 Lakota's on spec, on price and slightly ahead of schedule and the pilots seem to like it. So they might have a chance.
The Boeing AH-6S Little Bird, while a capable aircraft seems small to me, limited for future derivatives and moving people (inside).
