As has been correctly pointed out elsewhere, the illuminators on this class have a
three-bar support for the front reflector, not four (like SPG-60), with one support near the bottom of the dish. The
dark spots near the four corners of the SPY-1F are much less prominent than indicated on the drawing, and these radar arrays are 8ft x 8ft (yours are 19px high). There is some indication of a border around the radar face proper, so I would probably make them 18px high (13px wide when shown at a 45deg angle).
Otherwise a great drawing.
