This is a Saab 105, Sk 60C, the variant with the long
camera nose, here shown with its armament alternatives:
30 mm Aden gun pod or rockets.
A Saab J 35F2 Draken, as you can see from the IR seeker
under the nose (there were no J 35Js at this time).
Under the left wing is a semi-active Rb 27 Falcon missile, under the right a IR homing Rb 28 Falcon.
This is a Saab S 35E Draken. On the left under fuselage
station can be seen a night photo pod with cameras and
electronic IR flashes.
This photo shows off the armament options of a Saab AJ 37 Viggen.
From right to left:
135 mm rocket pods, 30 mm Aden gun pod,
Saab Rb 04E anti-ship missile, Saab Rb 05 general purpose missile
and on the bomb racks on the aircraft bombs, in this case
I think illumination flares.
The green colour denotes they are dummies.
