US Stealth And ATTACK Helicopter ⚔️ Boeing-Sikorsky RAH-66 Comanche [Review]

September 8, 2019


The Boeing–Sikorsky RAH-66 Comanche is an
advanced five-blade armed reconnaissance and attack helicopter designed for the United
States Army. Program cancellation
On 23 February 2004, the U.S. Army announced that they had decided to terminate all work
on the Comanche program. At the time, it was stated that the Army had
determined – a number of upgrades would be necessary for the RAH-66 to be capable of
surviving on the battlefield in the face of current anti-aircraft threats; however, the
Army had instead decided to re-direct the bulk of its funding for rotary development
toward the renovation of its existing helicopter fleet of attack, utility, and reconnaissance
aircraft. Specifically, the Army also had plans to reuse
the funds allocated to the Comanche program to speed up development of unmanned aerial
vehicles (UAVs), which could also perform the scouting role intended for the vehicle. Interesting to know
The Boeing–Sikorsky RAH-66 Comanche would have functioned as a stealth helicopter, incorporating
a number of different techniques and technologies in order to reduce its radar cross-section
(RCS) along with other areas of visibility and detectability. It was specifically tailored to the role of
armed scout to replace the U.S. Army’s OH-58D Kiowa Warrior, which is an upgraded version
of a Vietnam War-era observation helicopter. The RAH-66 was powered by a pair of LHTEC
T800 turboshaft engines, each capable of generating up to 1,563 hp of power. The RAH-66’s fuselage was 43 feet long and
composed of composite materials; it was designed to be capable of fitting more readily onto
transport ships, enabling the Comanche to be more rapidly deployed to flash points and
other rapidly-developing situations. However, in the event of strategic transport
assets not being available, the rotorcraft’s ferry range of 1,200 nmi would have allowed
it to fly itself to battlefields overseas on its own. The Comanche was to be equipped with sophisticated
avionics, including navigation and detection systems, which would have enabled operations
during nighttime and within challenging weather conditions. Its primary mission was to scout around using
its advanced sensors, attempting to find and designate targets for attack helicopters,
such as the AH-64 Apache, to strike. The Comanche was furnished with a digital
fly-by-wire flight control system. Each of the two crew members were to be provided
with a pair of LCD multi-functional displays which would have functioned in addition to
the Helmet-Integrated Display and Sight System (HIDSS) worn by the crew. General characteristics

  1. RAH-66 Has to be one of the most Aesthetically satisfying helicopters built to date, to me personally it's such an inspiring design that was quite fittingly emblematic of US technological expertise in military aviation (especially at that point in time). Great video as always, keep up the good work.

  2. They need to bring this babe back. Retrofit the engine to a methane turbine for greater fuel capacity and add some thermal camouflage to those retroflector panels to decrease lock on cross section 😎😎

  3. "Was"…and "Had"…..That says it all!… Stupid … Sorry folks…. your going to have to just make do with outdated equipment instead… after all.. the guys who decided to cancel these projects won't have to worry because it's not their asses that would be shot down! Stupid idiots!!

  4. Insider info may have or may not have said the money was redirected to antigravity systems. This can't be confirmed or denied

  5. а где вооружение,?на подвесе нельзя т.к теряется невидимость..пулемёт и пара гранат.?ну это не серьёзно..похоже на дорогую игрушку.

  6. The Army is a no-nonsense service branch. Unlike the Air Force, who has a near fetiche obsession with expensive high-tech gear just for the sake of being high-tech.
    cough F-35 cough

  7. I think this should’ve been the replacement to the Apache not the Sikorsky design. The Sikorsky one reminds me of the attempt on the Huey in Vietnam.

  8. THE RAH-66 CHOPPER AND THE AH-64 IN TANDEM WHAT A LETHAL COMBINATION ! THEY NEED TO PUT THIS CHOPPER IN PRODUCTION.

  9. I seriously doubt this helicopter was canceled. It was just too good! In fact, I bet this bird was suddenly classified and placed into a secret unit, like the f117.

  10. THE YF-23 AIRCRAFT AND THE COMANCHE DESIGN I WOULD KEEP ON THE BACK BURNER FOR FUTURE DEVELOPMENTS .BOTH SEEM TO HAVE POTENTIAL
