Pictures of the Argentine Air Force’s Learjet 35A were released earlier this month, depicting an aircraft modified specifically for countering electronic warfare.
Argentina has not has such an aircraft since retiring the Boeing 707 VR-21.
The Air Force acquired the 35A in 2013 and contracted Avcon Industries to make the necessary modifications to allow installation of a Thales Vigile 200 electronic support system.
Other modifications include tanks on the wingtips so antennas could be fitted, compartments and new wiring for antennas, a radome on the tail, and structural changes for delta wings to achieve better stability and efficiency.
I am not sure if the pictures are of the mentioned plane! But it is definitely not a standard Learjet
