DESCRIPTIONS OF VARIOUS B-66 VERSIONS

B-66B (Conventional and Nuclear Bomber)
The bomber was stationed at Hurlburt Field (Eglin #9), FL, and RAF Sculthorpe, England. First delivery of the B-66B was to Hurlburt Field during February 1956. It had a HF isolation strip on the vertical stabilizer, i.e., a "long wire" was attached from the top of the vertical stabilizer to the fuselage. (Like WW-II style communications). Also, In the bombay area, you would find large bombs in a large bombay area. The MD-1 fire control system was installed at the rear of the fuselage.

EB-66B (Brown Cradle)
Thirteen (13) B-66B's were converted to "Brown Cradle" ECM jammer configuration during 1958 - 1959. These models were known as the EB-66B:

RB-66B (Day/Night photo reconnaissance)
What would normally be a bombay area, had high resolution cameras and, to the rear of them, 48 photoflash bombs. The vertical stabilizer has an HF radio isolation strip. (The tip of the vertical stabilizer is "Isolated" from the rest of the aircraft and is the HF antenna.) The MD-1 fire control system was installed at the rear of the fuselage. Later, the bomb bay area was "Gutted" and ECM jammers installed to make it an EB-66E. This became one of the most powerful electronic jamming platforms in the AF inventory.

RB-66C (Electronic Reconnnaisance/Electronic Counter Measures (ECM)
There were four(4) crew member seats in a mid-fuselage EWO compartment, APD-4 wing tip pods, and a canoe radome of the lower/bottom fuselage containing electronic intercept antennae. RB-66C's also had Chaff-Dispensing/ECM tail cones, instead of the MD-1 fire control system.

WB-66D (Weather Reconnaisance)
The last airplane of the Douglas RB-66B/WB-66D production contract that was delivered to the Air Force from the Douglas-Tulsa facility. Instead of a four crew member seats in mid-fuselage, as in the RB-66C, the WB-66D had a two (2) crew member seating arrangement (No. 1 and No. 2 positions). There was weather measuring equipment in the area normally noted as crew station No. 3 and No. 4.
