At the center stands the <strong>Virupaksha Radar<\/strong>, an advanced AESA radar developed by DRDO\u2019s LRDE. This radar uses state-of-the-art technology to improve situational awareness, targeting precision, and mission reliability. Through this system, India ensures its air superiority amid evolving aerial threats.<\/p>\n\n\n\n<p>LRDE designed the Virupaksha Radar to meet current and future combat demands. It boosts the Su-30 MKI\u2019s capability in electronic warfare, tracking, and engagement. By using indigenous technology, India reduces dependency on foreign systems and strengthens defense self-reliance.<\/p>\n\n\n\n<p><strong>Virupaksha: The Beast in Making <\/strong><\/p>\n\n\n\n<p>The Virupaksha Radar will feature a GAN-based Active Electronically Scanned Array (AESA) architecture, offering superior thermal efficiency and power density over traditional GaAs systems. With 2,400 Transmit-Receive Modules (TRMs) almost twice the count of the Rafale&#8217;s RBE2-AA and significantly more than any radar in India\u2019s inventory, it promises exceptional target detection and tracking performance. The radar will deliver high peak power, extended range, and faster beam steering capabilities. Notably, it will incorporate electronic steering, similar to the Captor-E radar on the Eurofighter Typhoon, allowing wide azimuth coverage and agile beam control essential for modern aerial combat.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-1024x576.jpeg\" alt=\"\" class=\"wp-image-1408\" srcset=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-1024x576.jpeg 1024w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-300x169.jpeg 300w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-768x432.jpeg 768w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-1536x864.jpeg 1536w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-1320x743.jpeg 1320w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1-600x338.jpeg 600w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/Template.007-1.jpeg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><strong>How Virupaksha Radar Enhances Fighter Capability<\/strong><\/p>\n\n\n\n<p>The Virupaksha Radar includes eight Line Replaceable Units (LRUs) that together deliver unmatched performance. These include the Active Array Antenna Unit, Exciter Unit, and Radar Receiver Unit. Additional units such as the Antenna Positioner, Radar Processing Unit, and Cooling Unit form the radar\u2019s backbone.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-1024x1024.png\" alt=\"\" class=\"wp-image-1407\" srcset=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-1024x1024.png 1024w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-300x300.png 300w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-150x150.png 150w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-768x768.png 768w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-600x600.png 600w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46-100x100.png 100w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-46.png 1152w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Each component plays a key role in radar accuracy, range, and power management. The Radome and Antenna Power Supply round out the system. DRDO leads the design and development, while a Development cum Production Partner (DCPP) integrates it into IAF platforms.<\/p>\n\n\n\n<p><strong>DCPP Holds the Key to Program Execution<\/strong><\/p>\n\n\n\n<p>The DCPP must deliver not just components but a complete support ecosystem. It must possess skilled manpower, advanced infrastructure, and certified quality systems. Once selected, the DCPP oversees integration, flight validation, and large-scale production.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"767\" src=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-1024x767.png\" alt=\"\" class=\"wp-image-1409\" srcset=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-1024x767.png 1024w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-300x225.png 300w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-768x576.png 768w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-1536x1151.png 1536w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-1320x989.png 1320w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47-600x450.png 600w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-47.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Importantly, the DCPP must offer post-deployment support for at least 20 years. This includes spares, upgrades, training modules, and on-aircraft servicing. During this phase, LRDE will reduce involvement, shifting the core responsibility to the partner.<\/p>\n\n\n\n<p><strong>Four Phases Drive the Project Timeline<\/strong><\/p>\n\n\n\n<p>The program unfolds in four clear phases. First, the DCPP supports radar hardware realization while designing Ground Support and Automated Test Equipment. This lasts 16 months.<\/p>\n\n\n\n<p>Next, integration work begins and spans 15 months. During this period, engineers ensure seamless compatibility between aircraft and radar. Simultaneously, radar flight trials run for 9 months to verify in-air performance.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"767\" src=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-1024x767.png\" alt=\"\" class=\"wp-image-1410\" srcset=\"https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-1024x767.png 1024w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-300x225.png 300w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-768x576.png 768w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-1536x1151.png 1536w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-1320x989.png 1320w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48-600x450.png 600w, https:\/\/alphadefense.in\/wp-content\/uploads\/2025\/07\/image-48.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>The final stage grants production clearance. This two-month window allows full-scale manufacturing to begin without delays. Throughout, the DCPP must remain agile, as project scope may evolve with IAF needs.<\/p>\n\n\n\n<p><strong>Rights, Risks, and Future Orders<\/strong><\/p>\n\n\n\n<p>DRDO retains all design and intellectual rights for the Virupaksha Radar. However, after successful trials, the DCPP receives a non-exclusive production license. This enables it to produce and support the radar for the IAF.<\/p>\n\n\n\n<p>LRDE will initially deliver three radars for evaluation. After performance reviews, the IAF may order around 50 systems over 10\u201315 years. Although no number is guaranteed, the expectation is significant.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Indian Air Force (IAF) has launched a major upgrade for its Su-30 MKI fleet.
