The Indian Super Sukhoi program has run into a problem that cannot be solved by simply replacing the radar: the modernized Su-30MKI must simultaneously process data from multiple sensors, aircraft, and ground systems. The more information the fighter receives, the higher the demands not only on the computing system but also on communications and power supply. The IDRW publication drew attention to this problem.
According to the publication, the main shift is that the Su-30MKI is transforming from an aircraft with a set of individual sensors into a node of a distributed information system.
The new architecture must integrate information from the onboard radar, infrared search and track system, radiation warning equipment, AWACS aircraft, ground radars, drones, and other fighters into a single picture. The same object can be detected simultaneously by several sources, so the onboard computer will not just have to collect more data, but also recognize coincidences and form a single tactical track from multiple marks.
The problem extends beyond computational power. The more the Su-30MKI depends on data exchange with external sources, the more dangerous jamming, information spoofing, and loss of communication channels become. The aircraft must maintain combat capability even after disconnecting from the external network, simultaneously processing its own sensors and signals from electronic warfare systems.
Additional load also arises at the physical level: a powerful AESA radar, a new electronic warfare complex, computing equipment, communication tools, and displays will require more electricity and more efficient heat dissipation. The large airframe of the Su-30MKI gives India a margin for accommodating electronics, antennas, cooling systems, and additional equipment.
As a result, the Super Sukhoi faces the paradox of modern combat aviation: an increase in the number of sensors enhances crew awareness, but simultaneously turns information processing and protection into a separate critical task.
