Boeing Sikorsky Rah 66 Comanche Stealth Helicopter Overview

The Boeing-Sikorsky RAH-66 Comanche was a cutting-edge, stealth-capable, reconnaissance and attack helicopter designed to provide the United States Army with a next-generation, multi-mission aircraft. Developed in the 1990s and early 2000s, the Comanche was envisioned as a key component of the Army's Future Combat Systems (FCS) program.

The Comanche program was a collaborative effort between Boeing and Sikorsky, two of the world's leading aircraft manufacturers. The program aimed to create a highly advanced, fifth-generation helicopter that could perform a wide range of missions, including reconnaissance, surveillance, attack, and transport.

Design and Features

The RAH-66 Comanche was designed to be a highly agile and maneuverable aircraft, with a unique, angular fuselage that provided reduced radar cross-section (RCS) and infrared (IR) signatures. The helicopter's airframe was made primarily of composite materials, which helped to reduce its weight and increase its strength.

The Comanche was powered by two LHTEC T800-LHT-801 turboshaft engines, each producing 1,563 horsepower. The helicopter had a top speed of over 175 knots (200 mph) and a range of approximately 200 nautical miles (370 km). The Comanche's advanced avionics system included a advanced flight control system, a tactical mission system, and a comprehensive communication suite.

Stealth Capabilities

One of the Comanche's most distinctive features was its stealth capabilities. The helicopter's angular design and radar-absorbent materials (RAMs) helped to reduce its RCS, making it more difficult to detect by enemy radar systems. The Comanche's IR signature was also reduced through the use of advanced materials and design features, such as the helicopter's cooled exhaust system.

Armament and Payload

The Comanche was designed to carry a variety of armaments and payloads, including missiles, rockets, and guns. The helicopter had a total of six external hardpoints, which could be used to carry up to 1,000 pounds (450 kg) of payload. The Comanche's advanced avionics system allowed it to accurately deliver precision-guided munitions, such as the AGM-114 Hellfire missile.

Avionics and Electronics

The Comanche's advanced avionics system was one of its most impressive features. The helicopter had a highly integrated cockpit, which included a large, flat-panel display and a pilot's control and display unit (PCDU). The Comanche's avionics system also included a advanced navigation system, a communication suite, and a tactical mission system.

Program Cancellation

Despite its advanced features and capabilities, the RAH-66 Comanche program was canceled in 2004 due to rising development costs and delays. The program was initially estimated to cost $34 billion, but the final cost was estimated to be over $50 billion. The cancellation of the Comanche program was a significant setback for the U.S. Army's Future Combat Systems (FCS) program.

Legacy

Although the RAH-66 Comanche program was canceled, the helicopter's advanced design and features have influenced the development of future aircraft. The Comanche's stealth capabilities, advanced avionics, and precision-guided munitions have set a new standard for military helicopters.
