I'm sorry, but when it comes to Comanche you don't know what the hell you're
talking about. Given that you can't even spell Comanche properly, I
shouldn't be surprised.

The Comanche radar is not "taken from the LONGBOW" as Ron says. Nor does it
have "many common parts with the AH-64 longbow" There are zero common
parts. Comanche radar is a total rehosting and regeneration of the basic
longbow system on a completely digital platform. The only thing in common
is the idea of a mast-mounted targeting radar. Neither our antenna nor our
radar controls are common with Longbow. As a matter of fact, one of the HTI
efforts from Comanche leftovers is to take our digital Radar Electronics
Unit (REU) and our low Radar Cross Section radar antenna (both of which are
much lighter than the longbow system) and put them in the next generation
AH-64.

Full Fly-by-wire is planned for the AH-64, again based on Comanche
technology. The idea is to have a common FBW software set for the AH-64 and
UH-60, with an overlay for the specific aircraft.

As for the antitorque system, I'd dearly love to hear about this mysterious
new technology - I'm an aerodynamicist by trade, and I'm not aware of any
new antitorque technologies within the last 40 years or so.

Thanks Ron, The AH-64 is an live and evolving system, the improvements I

mention
are for new units, and some exist only in study as the landing gear, the

tail
rotor, and the Full FlyByWire, on the tail rotor, I think that exist better
solutions than the fenestron or the Piascecki ducted fan or the Notar, But

is
classified material, you know that in some circumstances a research team

for a
system don't have access to the work of other teams, unless the system

being
developed have common elements, the commanche's radar is more compact and

has
less radar section, and have many common parts with the AH-64 longbow, the
improvements to the rotor system are for new units and for a limited number

of
old units, I don't know its current stage, but surely prior 2010 will not

enter
in service, as the "New" AH-64X.

I'm not a pilot, I'm a systems engineer, we put the ideas, the crews the
