Finding A Niche

India’s procurement of an estimated five squadrons of s-400 Triumf Sam Systems from Russia has evoked the ire of the united states which has threatened sanctions over the deal. Whether or not this comes to pass, the threat has soured the heretofore positive defence relationship between India and the United States.

India’s Ground-Based Air Defences

The Indian Air Defence Ground Environment System (ADGES) employs a three-tier detection network. While this system is currently in the process of a major modernisation programme, the basic structure of the ADGES network will remain unchanged. The first layer, rather surprisingly, consists of Mobile Observation Posts (MOP). These remain among the most reliable of the early-warning mechanisms available to the Indian Air Force. The MOPs consists of two-man teams equipped with a HF/VHF radio set and field glasses. The personnel in the MOP are well versed in the visual identification of aircraft as well as their general direction of flight. The MOPs are scattered along the borders at random intervals, ranging between 25 and 45 kilometres. The MOPs usually give the first warning of airborne intrusion, the general direction of the attack and, mo
