This super-stealthy light attack helicopter, bristling with advanced sensors and communication gear, was going to perform loads of armed reconnaissance and surveillance missions. The initial design had weak directional stability and was determined to be not acceptable. The Next Generation of Aircraft Technology. Reconnaissance and attack helicopter. Split Torque main gearbox.

Split Torque main gearbox. This included a search-on-the-move function; moving target detection; and automatic multitarget prioritization, comanchs, weapons selection and fire control. Williams, James W Army Comanche unit was projected to be operationally equipped in No extreme rolling required.
Navigation and tactical overlays were provided on a digital map for tactical awareness and easier, more thorough mission planning. What might we learn from Comanche? Production quantity was reduced from 1, towith a peak annual build rate of 60 aircraft per year.
In the spring of the Lockheed Martin Night Vision Pilotage System was delivered for integration into the aircraft. Despite the challenges the development and flight test programs were generally successful. This was named Shadow. For a full Hellfire loadout an external stores rack was installed which could hold eight additional Hellfires.
Boeing / Sikorsky RAH Comanche Reconnaissance / Light Attack Helicopter – United States
The smooth composite fuselage exterior was designed to not deteriorate when decontamination cleaners were used. Flight testing took only six weeks, and included a full maneuver envelope. Both the radar and IR signatures were well below the Army specifications.
The flight controls were fly-by-wire with a right sidearm controller for pitch, roll, and yaw control. There were three main 30kw generators; two driven by the main gearbox and one by the SPU. Retrieved 8 July Archived on 22 July Retrieved 18 July When the pressure is reduced, the gas is released, or desorbed.
Ballistic tolerance was projected to be 50 times better than existing helicopters. Archived from the original PDF on 28 August The system was designed to be highly fault tolerant, reliable and survivable.
Symbology for heads-up and eyes-out operation was included. Its primary mission was scouting using its advanced sensors, in particular locating and designating targets for attack helicopters, such as the AH Apache, to strike.
Sikorsky Product History
As cokanche program progressed this schedule was delayed many times as a result of the Army reducing the yearly funding and adding additional requirements. This strongly affects the rotor control power and dynamic characteristics.
From the 16th Comanche onwards, deliveries would have been made to the Block II standard, which was to have all of the planned capabilities included.
The RAH was the world’s first purpose-built stealth attack helicopter complete with fully-powered internal bays housing anti-armor and anti-air comance and promoted heavy use of stealth materials to help conceal its approach from enemy radar. Specifically, the Army also had plans to reuse the funds allocated to the Comanche program to speed up development of unmanned aerial vehicles UAVs comancbe, which could also perform the scouting role intended for the vehicle.

Boeing–Sikorsky RAH-66 Comanche
But a funny thing happened with Comanche, making it worth a look. It included the helmet displays, commercial processors, and functional cockpit displays. Perhaps the lesson is that military tech programs should exercise design restraint, establish strict budget and schedule constraints, and rely on proven technologies to deliver necessary capabilities on operationally relevant timelines.
