Douglas F5D-1 Skylancer

[overscan (PaulMM)]

Sparrow I and Sparrow II were both given as armament options for the Skylancer. Sparrow III would have required a CW illuminator and probably a larger radar antenna, not feasible really given its size.

Makes a lot of sense;: SARH is the most demanding guidance for the radar, and Phantom APQ antenna grew from 24 inch to 32 inch on the prototypes.
Sparrow I guidance was pretty dumb, Sparrow II was mostly autonomous - when it worked..

Interesting that these drawings depict a very different windscreen and canopy than actually built. In fact, I don't think I have seen it in any other drawings or models. It is very similar to the very early A4D canopy...
