US Navy High Performance Observation Reconnaissance competition (1955)

[Stargazer]

This little-known competition found in the Spangenberg Index apparently produced no winner:

• Bell D-179
• Bell D-220 Convertiplane
• Cessna (designation unknown)
• Doak 15A
• Fairchild M-229
• Goodyear (designation unknown)
• Hiller (designation unknown)
• North American ESO-7607
• Piasecki PR-107
• Temco (designation unknown)

Note that the Bell D-220 Convertiplane is not the XV-3 (Model 200), although it is probably a related design. Any other details about this competition and/or its contenders is most welcome!

My dear Stargazer,

the Bell D-220 was observation-recce version of XV-3 powered
by two General Electric T58 turbine engines.
