Product description

 

The Lockheed "Hopeless Diamond" was a computer-generated and later 10-foot wooden model created by Lockheed's Skunk Works in the mid-1970s to test and demonstrate their concepts for stealth aircraftThis faceted, tail-less design was intended to minimize an aircraft's radar signature, with a small model achieving a radar reflection "as small as an eagle's eyeball". While not a flyable aircraft, the lessons learned from the Hopeless Diamond's development were incorporated into the subsequent Have Blue program and the resulting F-117 Nighthawk stealth fighter. 
 
Purpose and Design
  • Stealth Technology:
    The Hopeless Diamond was a conceptual design for a stealth aircraft, and its primary goal was to prove the effectiveness of faceting the exterior of an aircraft to reduce its radar signature. 
     
  • Early Stealth Research:
    It was developed as part of the Defense Advanced Research Projects Agency's (DARPA) investigations into minimizing radar signatures, with a computer-generated shape being the starting point. 
     
  • Radar Test Model:
    A 10-foot wooden model of the design was built and subjected to radar tests, demonstrating the potential of the faceted design. 
     
  • Influence:
    The research and development from the Hopeless Diamond concept were crucial to the evolution of stealth aircraft, eventually leading to the first prototype, Have Blue, and the operational F-117 Nighthawk stealth fighter.
