117 — Poly 117rar

: In 1974, computers were not powerful enough to calculate radar reflections on curved surfaces. Lockheed engineers used Soviet algorithms to calculate reflections on flat triangular surfaces (facets) instead.

The F-117 is famously described as the "Original Low-Poly Stealth Art" because its faceted, angular appearance was a literal limitation of 1970s computing. 117 Poly 117rar

: Write-ups often compare the "117" nomenclature across fields, such as the high-output Milwaukee-Eight 117 engines used in Harley-Davidson motorcycles , which produce 114 horsepower. : In 1974, computers were not powerful enough

: A frequent topic is how a Serbian SAM battery managed to down an F-117 by using long-wavelength radars and observing the "holes" in the RF spectrum created by the stealth aircraft. : Write-ups often compare the "117" nomenclature across

: The initial design was so aerodynamic-challenged it was nicknamed the "Hopeless Diamond" before fly-by-wire technology made it flyable. Key Elements of the Write-up
