RAH-66 COMANCHE STEALTH HELICOPTER
Boeing Sikorsky RAH-66 Comanche is the world's most advanced
helicopter and the cornerstone of the U.S. Army's Force XXI
aviation modernization plan. The Comanche makes use of the latest
advancements in aerospace technology, including stealth which
has until now been confined to airplanes.
The sophisticated design of the Comanche helicopter allows it
to dash to a speed of 175 knots, then cruise at a steady 165.
The futuristic propulsion and navigation design also allows
the helicopter to execute snap turns in 4.5 seconds and fly
sideways or backwards at an incredible 70 mph! With a tremendous
power output of 1,432 horsepower from each of it's turboshafts,
the Comanche climbs at a rate of 1,418 feet per minute.
The Comanche can go to war with up to 14 "Fire and Forget" Hellfire
anti-tank missiles, which, once fired, are programmed to control
their own flight to their targets. The helicopter can also deploy
up to 56 rockets (70mm), or 28 Stinger air-to-air missiles,
to attack fixed and rotary-wing targets.
Alternatively, it can carry two 430-gallon ferry tanks to self-deploy
over 1,260 nm, or crashworthy 230-gallon tanks for more than
four hours of combat endurance.
Adding to its already immense firepower, the Comanche also stows
a three-barreled, 20 mm turreted nose mini-gun that can shoot
1500 rounds per minute.
To maintain its low "stealth" profile, the Comanche features a
fully retractable missile armament system, enabling it to hide
missiles and rockets in I-RAMS (Integrated Retractable Munitions
using computer databases, Comanche redefines the helicopter in
terms of power, maneuverability, technological sophistication,
and materials engineering. Twin LHTEC-800-LHT-801 turboshaft engines
drive an advanced five-blade, bearingless main rotor which further
enhances high performance and agility in air-to-air combat. Its
FANTAIL anti-torque tail rotor system lets Comanche execute amazing
maneuvers near impossible for other helicopters.
Comanche also features reconfigurable, fault-tolerant digital
missions electronics and on-board diagnostics, Longbow fire-control
radar, triple-redundant fly-by-wire flight control and simple,

symbology with sensor images to
allow aggressive flight maneuvering at night.

addition, the RAH-66's Hands On Grips controls literally let pilots
fly and perform mission tasks with one hand - a first-ever achievement
in a helicopter.
The Comanche also breaks new ground in the use of high technology
composites to satisfy both Low Observable Technology requirements
and aggressive weight and cost specifications.
Warrior in the Digital Battlefield
Its on-board computing capability enables Comanche to acquire,
process, analyze and disseminate an amount of information unsurpassed
by today's helicopters. Comanche's low radar signature, high technology
composites, special acoustics design, and a buried exhaust system,
make it less observable than today's premier attack and armed
Add to this new generation of passive long-range, high-resolution
battlefield sensors, digital interconnectivity, to share data
with other members of the combined arms team, produces a completely
integrated targeting, and communications weapon system, facilitating
the delivery of quick, coordinated responses to tactical situations
with minimal work for the pilot.
