The Comanche II is a upgraded version of the original -66 that went into production in 2005, this new model has upgrades that
the following text will explain. The Comanche is equipped with a suite of passive sensors which provide a target identification
range 2 times greater than provided on current generation helicopters. To enhance the survivability, a computer aided mission
planning system is provided. The on board computer systems carry out sensor data fusion, high speed analysis and correlation
of the sensor data. The analysed target and battlefield situation data is presented to the crew in the cockpit displays or
transmitted to other elements of the force, providing direct relay of near real time intelligence.
The Comanche is equipped with a stowable three-barrel 20 millimetre Gatling gun from General Electric. The gun, with up to
500 rounds of ammunition, is mounted on a Giat turret under the nose of the helicopter. The Gatling gun is capable of firing 750
or 1,500 rounds per minute. The fairing permits aiming coverage of the gun from +15° to -45° in elevation and ± 120° in
azimuth; the unit may also be stowed at 2° elevation and 180° azimuth to reduce radar signature.
The Comanche carries its weapons internally and has a weapons bay on each side of the fuselage. The missiles are mounted on
the weapon bay doors which open sideways. The missiles fire within three seconds of the bay doors opening. The number of
missiles on each door mounting varies according to the size of the missile system, for example eachdoor will hold three Hellfire
or six Stinger missiles. The helicopter can be reconfigured with optional stub wings fitted with multiple weapon pylons which
carry an additional four Hellfire II or eight MRAAM missiles. The nose of the helicopter houses an infra-red piloting sensor
incorporating a low visibility image intensifier. The long range second generation forward looking infra-red (FLIR) system and
television targeting sensor is also located in the nose. The Comanche will be fitted with a fire control radar which may be the
Longbow fire control radar from Northrop Grumman, currently used on the Aztechology Augular, and Max Tek Pegasus
(Which Replaced the Apache Longbow). The helicopter is equipped with a laser warner, radar warner and radar and infrared
jammers.
The Comanche has two identical cockpits in a stepped configuration for the pilot and the co-pilot. The cockpits are sealed and
have a positive pressure air system for protection against chemical and biological warfare. The crash resistant crew seats are
rated to resist a 40 feet per second vertical landing. The cockpit is fitted with a night vision pilotage system from Lockheed
Martin. The targets are designated and the weapons fired from collective and sidestick control push buttons. Each integrated
cockpit has flat screen liquid crystal displays, a colour display for a moving map, tactical situation and night operation display.
The digital map system is an upgraded version of the systeminstalled on the F-120. The avionics is based on three redundant
databuses, a current generation Military Standard 1553B bus, a high speed and a very high speed fibre optic bus for signal
data. The helicopter is equipped with an identification friend or foe (IFF) interrogator and a dual jam resistant VHF-FM /
UHF-AM Have Quick tactical communications system. The helicopter has a global positioning system, a radar altimeter and an
attitude heading reference system, AHRS, from Litton. The internal fuel capacity of the helicopter is 1,142 litres. In field
conditions three soldiers can refuel and rearm the Comanche in less than 15 minutes.
The small cross-section and the all-composite airframe construction of the Comanche provides very low detectability. The
airframe is crashworthy and ballistically tolerant to 23 mm gunfire. In the event of impact the Comanche's separate redundant
systems help assure safe return. The helicopter systems are hardened against electromagnetic interference. The radar cross
section has been minimised, primarily by the precisely shaped fuselage and internal weapons configuration. A low acoustic
signature is achieved by an advanced rotor design. The helicopter has a five-bladed bearingless main rotor and a fantail
anti-torque system. The rear rotor is able to withstand impact by 12.7 mm rounds and operates for 30 minutes with one blade
missing. The rear rotor provides a 180 degree turn in 4.7 seconds in hover mode and an 80 knot snap-turn-to-target in 4.5
seconds. Cooled engine exhaust and cool aircraft skin provide low detectability by hostile infra-red sensors.
