RAF Woodbridge Open House 7th August 1976.

To add to MikeH’s comments the two boxes under the wings were combat documentation cameras, cine cameras that would record bombing footage. They were standard on F-4Es from Block 45 (69-7579) and retrofitted to about fifty earlier ones, mostly in PACAF. About 80 F-4Ds had them too, all retrofitted.

Another poster commented that the F-4Es looked new. They were exactly that.

Thank you Herbert!
