The Indian Air Force operates a single Gulfstream III SRA , registered as VT-ENR, for ELINT duties. The aircraft is usually based at Palam Air Force Station and is targeted almost exclusively against Pakistan.
A regular visitor to the site sent me the following photos and asked if I knew which country operated this mysterious Gulfstream III. The aircraft is devoid of national markings (probably digitally removed) and is fitted with what appears to be a LOROP camera pointing out of a window in the front part of the starboard fuselage and possibly other cameras looking out of the bottom of the fuselage.
I suspect that the aircraft is actually operated by India, as they operate at least one other Gulfstream III for ELINT operations painted in a very similar colour scheme, so using another for photo reconnaissance makes sense. However, there are a number of other possibilities and I am keen to hear from anyone who can positively identify who operates this unique reconnaissance aircraft.
