Rah-66
Comanche
The U.S. Army's aviation modernization
plan has as its centerpiece the Boeing-Sikorsky RAH-66
Comanche armed reconnaissance helicopter.
The aviation plan reflects the Army's new post-Cold War
strategy to react to regional conflicts
by using fewer personnel and long-range, self-deployable aircraft based
in the continental United States.
The Comanche
is a twin-turbine, two-seat (tandem) armed reconnaissance helicopte with
projected missions of armed reconnaissance, light attack and air combat.
Initial operating capability is set for the year 2006.
It will
replace obsolete AH-1 and OH-58 attack and observation helicopters. The
Comanch has capabilities demanded of a smaller force structure, such as:
improved mobility, increased survivability and dramatically reduced operation
and support costs. Initial operating capability is set for the year 2006.
Program
Emphasis
of the demonstration/validation program is to prove all critical components.
These include mission equipment avionics and a growth version of the Comanche’s
T800 engine. Two prototype
aircraft are being built. The Defense
Department’s Defense Acquisition Board has approved an early
operational capability program
that will provide for six additional aircraft, manufactured in 2001, for
U.S.
Army operational testing.
