[ARC5] SB2C at National Museum of Naval Aviation

[Edward Greeley]

There is an interesting article about the "Helldiver" on Wikipedia. That 
article says the SB2C-3 and SB2C-5 were equipped with AN/APS-4 radar. 
The APS-4 was the "cute" little X-band set that was entirely housed 
(except for the indicator and control box) in a sort of bomb-shaped pod 
that was carried under the fuselage or a wing. Always wanted one of 
those suckers, but by the time I had $$$ to spend on such things they 
had all disappeared from the surplus market...

These 3 units are hanging by their cables so may have been mounted in shock mounts over the wing.   What appears to be an ASB power control box is on the port side of the gunner's cockpit.  Also, above this area are the two ASB antenna control  levers which appear to be handy to the gunner's left hand while at his right hand are the CRT display front panel controls.

As the aircraft was ditched into the lake dead stick, it was moving at 100 knots or more, so I expect to not find the radar antennas still under the wings (not yet unloaded) nor any other antennas under the wings.
