I like the Comanche - Hokum cockpit thrown in for good measure.

Nice chopper, they fixed the issues then $6B down the drain, another Army success story.

A recent donation include a tube with this poster nicely protected in it....

Had to chuckle at "Light Helicopter" though!

Enjoy the Day! Mark

Indeed the original specification was for an aircraft that weighed only slightly more than the OH-58A/C that it was to replace.
I imagine that did not last past the first reading of the proposed specification. U.S. Army Aviation has a bad habit of ignoring physics when writing requirements.

Several Rockwell HIDE 'stealth' engineers went to Sikorsky on loan....

When the Rockwell crew arrived in Connecticut in 1991, Sikorsky had recently won a large Army contract. Sikorsky was in the very early phases of the RAH-66 Comanche helicopter design. The Comanche helicopter was being designed as the first low observable helicopter. Sikorsky, a world leader in helicopter design, had little or no experience in low observables. They must have benefitted greatly from the experience of the Tulsa engineers. Glen Hilderbrand recalled that the Sikorsky team was in some disarray at the beginning of the program, and the Rockwell team was often unsure what they were supposed to be doing.

Honestly makes sense. If someone needs to either analyze their in-house design or get the in-house engineers up to speed, the fastest way would be to hire one of the companies that has solid stealth experience.

And while it's off-topic here, I'm starting to wonder if a modern graphics program could estimate an aircraft's return in real time. ... Unreal3 to name a current and affordable one, Lightwave if you've got money.
