Operation Safed Sagar: What are photo recce missions shown in Netflix show, why are they crucial?

Operation Safed Sagar is a Netflix series that portrays the aerial operations conducted by the Indian Air Force (IAF) during the 1999 Kargil war. A key aspect of these operations was the photo reconnaissance (photo-recce) missions executed by various IAF fighter squadrons, particularly the No. 17 'Golden Arrows' squadron which flew MiG-21 aircraft.

These missions, carried out by multiple IAF fighter squadrons, were crucial in determining the extent of the Pakistani incursion along the Line of Control. Photo-recce missions involve fighter or fighter-derived aircraft capturing imagery of an area, installation, or activity for intelligence purposes, rather than engaging the target.

This is distinct from strike and air defense missions, which aim to destroy a specific target and locate and engage enemy forces, respectively. Photo-recce missions are used for mapping enemy positions, identifying targets for future strike missions, assessing damage after air strikes, monitoring military activity, and updating intelligence on enemy deployments and defensive positions.

They can also be utilized to conduct terrain or route reconnaissance, particularly in challenging or contested areas, assist in battle-damage assessment, and provide imagery for mission planning. Historically, photo-recce missions relied on older cameras with photographic film, which were later developed into high-resolution images.

During the Kargil war, the MiG-21s used the Vinten 751 camera, a British camera installed in a Russian fuel tank, allowing for low-level photography. Air Chief Marshal B S Dhanoa, then the Commanding Officer of the No. 17 'Golden Arrows' squadron, noted that this camera's shorter focal length provided a wider field of view, enabling the aircraft to capture images from lower altitudes.

As technology advanced, photo-recce missions evolved with the advent of drones and satellites. Today, fighter jets like the Jaguars and Su-30s perform photo reconnaissance missions, but they are increasingly complemented by real-time imagery relayed from ground stations via light pods and targeting pods. While satellites and drones provide real-time ground imagery, fighter photo-recce missions remain essential during wartime, as they offer immediate, high-speed photography capabilities that satellites and drones cannot match.
