Operation Sindoor: The weapons that gave India the edge
Written by Arindam Goswami and Vikrant Shinde
Operations Sindoor and Bunyan Marsoos constituted a sharp and intense three-day engagement and yielded significant lessons on the infusion of technology into warfighting. The contest played out across multiple domains: diplomacy, economy, military, and information. The military aspect spanned non-kinetic, kinetic, contact, and non-contact engagements.
India and Pakistan appear to have drawn lessons from the Balakot strikes (India) and Operation Swift Retort (Pakistan), as well as from ongoing wars in West Asia and Eastern Europe. Both armed forces, equipped with inventories from opposing blocs — India with Russian, French, US, and indigenous platforms, and Pakistan with Chinese, US, and Turkish systems — have grappled with the challenges of restricted cross-platform integration going into this engagement.
Both air forces were acutely aware of the challenges of employing air power in a contested air defence (AD) environment. The nature of the conflict did not allow the luxury of time to shape the air situation through dedicated Suppression of Enemy Air Defences (SEAD) or Destruction of Enemy Air Defences (DEAD). Consequently, both air forces sought to operate outside each other's AD bubbles using a variety of beyond-visual-range (BVR) air-to-air missiles (AAMs), such as the US-made AMRAAM and Chinese PL-15 (by the PAF), and the Meteor (by the IAF), alongside air-to-ground munitions such as air-launched cruise missiles (ALCMs) including SCALP and HAMMER employed by the IAF.
The employment of kinetic strikes deep into Pakistan, dominated by air power from the outset, had the potential to escalate rapidly and uncontrollably. India's reliance on precision targeting facilitated escalation control by minimising collateral damage, thereby providing Pakistan with an off-ramp.
Active electronically scanned array (AESA) radar technology was another important factor in modern air combat capability. Unlike older passive electronically scanned array (PESA) systems, AESA radars offer superior target detection and tracking, as well as enhanced resistance to jamming. The ability to simultaneously track multiple targets while maintaining a low probability of interception provides a significant combat advantage. This combination affords aircraft equipped with AESA systems a decisive edge in air-to-air engagements.
India currently faces a modest capability gap in this domain. It possesses only around 30–40 AESA-equipped aircraft, primarily Rafales and a limited number of Su-30MKIs with upgraded AESA radars. In contrast, Pakistan fields over 70 AESA-equipped aircraft, including approximately 20 J-10CEs and around 45–50 JF-17 Block III jets fitted with the KLJ-7A AESA radar. These JF-17 Block III fighters are integrated with advanced PL-15 air-to-air missiles, significantly enhancing their BVR combat effectiveness. Similarly, the J-10C aircraft are also equipped with PL-15 missiles. This technological disparity creates a potential vulnerability in India's air defence posture.
However, India has made notable strides in addressing this imbalance. The acquisition of Rafale fighters has been particularly impactful. These aircraft can track over 40 targets and engage multiple threats simultaneously — a capability that far exceeds that of the Su-30MKI's PESA N011M Bars radar, which can track approximately 15 targets and engage up to four. Thus, the Rafale jets, equipped with the RBE2 AESA radar and Meteor missiles (with ranges exceeding 150 km), provide a distinct advantage in radar capability, missile range, and electronic warfare over Pakistan's JF-17s and J-10CEs.
The most significant enhancement to India's air defence capability, however, came through the 'Akashteer' AD management system and the IAF's Integrated Air Command and Control System (IACCS). The legacy systems included IGLA Man-Portable Air Defence Systems (MANPADS), and Bofors L-70 guns — both of which have been significantly upgraded with radar, electro-optical sensors, and auto-tracking systems, including the Soviet-origin Schilka. The advanced AD systems fielded included the indigenous Akash (SRSAM), the Barak (MRSAM) developed jointly with Israel, and the S-400 (LRSAM), one of the most advanced AD systems in the world.
India also deployed indigenous Counter-Unmanned Aerial Systems (C-UAS), developed by BEL and private industry, capable of both soft-kill electronic warfare techniques (such as jamming and spoofing) and hard-kill options using directed energy weapons like lasers. These systems were extensively used to counter incursions by surveillance and combat drones.
Drones were deployed extensively by both sides to saturate the airspace and test air defence systems. The use of HAROP loitering munitions to target radars created potential gaps in AD coverage during the early stages. These munitions combine the features of UAVs and missiles, equipped with electro-optical (EO), infrared (IR), forward-looking infrared (FLIR) sensors, colour CCD cameras, and anti-radiation homing capabilities. HAROPs can loiter in a designated area for up to nine hours. Due to their immunity to GNSS jamming, they are largely resistant to electronic warfare attacks. Their relatively low cost and expendability make them likely candidates as weapons of choice in future 'no-war, no-peace' scenarios.

Allahabad HC dismisses Rahul Gandhi's plea against summons for remark about Army
The Allahabad High Court on Thursday dismissed a petition filed by Congress leader Rahul Gandhi challenging the summons issued by a Lucknow court in a defamation case related to his remarks about the Indian Army in 2022, Bar and Bench reported. The leader of the Opposition in the Lok Sabha had challenged the summons issued by Additional Chief Judicial Magistrate Alok Verma in February and the complaint filed against him on the grounds that it was motivated and lodged in a mala fide manner, The Times of India reported. Justice Subhash Vidyarthi on Thursday rejected the plea on merits, according to Bar and Bench. The detailed order of the judgement will be released on June 2, the Hindustan Times reported. Gandhi made the comments on December 16, 2022, about a clash between the Indian and Chinese armies along the Line of Actual Control in Arunachal Pradesh's Tawang. The two sides had confronted each other with melee weapons on December 9, 2022, leading to injuries in both sides. Gandhi's remarks about the violence were made during the Congress' Bharat Jodo Yatra, a march from Kanyakumari to Kashmir against the allegedly divisive policies of the ruling Bharatiya Janata Party. A former director of the Border Roads Organisation, Uday Shankar Srivastava, filed a defamation complaint against Gandhi. His lawyer claimed that the Congress leader's statements were derogatory and defamed the Indian Army.

Laura Loomer Calls For Xi Jinping's Daughter's Deportation From US Amid Student Visa Row
Last Updated: Spotlight turned to Xi Mingze, the daughter of Jinping after Loomer claimed that she is living in Massachusetts under heavy security. American far-right MAGA activist Laura Loomer has called for the deportation of Chinese President Xi Jinping's daughter following US Secretary of State Marco Rubio's announcement that the United States will begin 'aggressively" revoking visas of Chinese students. 'The US will begin revoking visas of Chinese students, including those with connections to the Chinese Communist Party or studying in critical fields," Rubio said in a post on X. Rubio added that the State Department will revise visa criteria to impose stricter scrutiny on all future applications from China and Hong Kong. Spotlight turned to Xi Mingze, the daughter of Jinping after Loomer claimed that she is living in Massachusetts under heavy security. 'LET'S GO! DEPORT XI JINPING'S DAUGHTER! She lives in Massachusetts and went to Harvard! Sources tell me PLA guards from the CCP provide her with private security on US soil in Massachusetts!" she said on X. Loomer declared that she intended to question Xi Mingze about her father's policies, saying, 'Communists don't belong in our country." Xi Mingze has remained intensely private, with most details of her life shrouded in secrecy. She studied under a false name at Harvard University from 2010 to 2014, majoring in psychology, after previously attending Zhejiang University and the Hangzhou Foreign Language School. Who Is Laura Loomer? The 31-year-old Loomer first shot to the limelight through her far-right activism, putting forth her controversial views on Islam and her incendiary statements. According to Firstpost, Loomer ran for US Congress in Florida's 21st district in 2020, winning the Republican primary. However, she lost the general election to Democrat Lois Frankel and her subsequent bid in 2022 too was unsuccessful. China swiftly condemned the US government's visa crackdown as Foreign Ministry spokesperson Mao Ning labeled the move 'politically motivated" and accused Washington of weaponizing ideology under the guise of national security. 'The US decision to revoke visas is entirely groundless. It harms the legitimate rights of Chinese students and damages educational and cultural exchanges. China firmly opposes this move and has lodged an official protest," Mao Ning said. International students – India and China together accounting for 54% of them – contributed more than $50 billion to the US economy in 2023, according to the US Department of Commerce. The Trump administration has broadened social media screening for foreign students and is pushing to increase deportations and revoke student visas as part of its broader hardline immigration strategy.

Chinese students rattled by Trump plan to 'aggressively' revoke visas
Students said the latest move had upended their plans and intensified their fears NYT By Robert Chiarito, Sharon Otterman, Jill Cowan, Shawn Hubler and Felicia Mello It had been all figured out, Cici Wang said. Summer at home in China, then back to get her master's degree in Chicago. After that, if she was lucky, a job in the United States. Now all of that is up in the air, she said, a potential casualty of a crackdown that has upended the future for more than 277,000 Chinese nationals studying in this country. 'Hopefully, I'll be fine,' said Ms. Wang, a 22-year-old aspiring computer scientist, sitting with her parents in the stately main quad of the University of Chicago on Thursday. 'But I'm not sure.' Across the country, Chinese students reeled Thursday from Secretary of State Marco Rubio's announcement that the Trump administration would begin 'aggressively' revoking visas for Chinese students studying in the United States. More than two dozen students studying in the United States, most of whom did not want their names published for fear of retaliation, told The New York Times that they worried they could lose their academic opportunities in an instant, with little explanation. In a statement late Wednesday, the State Department announced it was focusing on those who were studying in 'critical fields' or who had ties to the Chinese Communist Party and was revising visa criteria to 'enhance scrutiny' of all future applications from China, including Hong Kong. The vague parameters had a chilling effect on Thursday as students wondered how broadly the Trump administration would apply its new criteria. Mr. Rubio did not define 'critical fields,' but science students felt particularly vulnerable because American officials have expressed concerns about the recruiting of US-trained scientists by China. Nor was it clear how American officials would determine which students had ties to the Communist Party. The news came amid heightened tensions with China, a broad push to slash the number of immigrants in the United States and major headwinds in court for the Trump administration on global tariffs. China is a top target in President Trump's trade war. Student visas offer a potent tool for the Trump administration, if the courts allow it. Roughly a quarter of the nation's total international student population is from China, a cohort larger than any except Indian students, according to a report published last year by the State Department and the Institute of International Education, a nonprofit group. Professors and laboratories depend on the students' skill as teaching assistants and researchers. At public colleges, university administrators rely on the full tuition Chinese students typically pay to help subsidize the education of in-state students. At campuses large and small, Chinese students are an American fixture. At the University of Southern California, where international students have for decades been crucial to the campus's academic and business model, Chinese students make up about an eighth of the 47,000-member student body. 'Our international students are vital members of our Trojan family and have been since our founding in 1880,' USC.'s president, Carol Folt, said in a statement on Thursday. 'This is a confusing time.' From New York to the Midwest to California, students called the decision worse than confusing. At Columbia University, where about 6,500 Chinese students were enrolled last year, several Chinese students asked to be referred to only by their English first names, fearing retaliation from the US authorities. Caroline, 22, who just graduated with a bachelor's degree in art history, said that she was leaving next month for Canada, where she had gone to high school. 'I'm looking forward to it,' she said. 'This place doesn't feel welcoming anymore.' Her friend, Jack, 22, had just earned a bachelor's degree in computer science and was going to stay to work for one year as a full-time research assistant. However, he was rethinking his plans to apply to doctoral programs because they require a five-year commitment, and he worried that his visa status could be threatened during those years. Instead, he said, he might look at Canada, Europe or Hong Kong. The two had just been talking about Mr. Rubio's comments and trying to figure out what they meant. 'That word 'aggressively' is really horrible,' he said. At the University of North Carolina in Chapel Hill, where Chinese students have long made up the largest share of the international student population, Elle, 24, a master's degree candidate who had been planning to apply in the fall to a Ph.D. program, said that she couldn't stop looking over her shoulder. 'People are worried about liking the wrong thing on social media or even getting a speeding ticket because it might mean the end of all their hard work and time in America,' she said. 'In April and March, six students had their visas revoked at my university. Who's to say I'm not next?' In Pennsylvania, Taylor, 23, a physics major, had just graduated from a liberal arts college so small she asked that it not be named because officials might identify her. Though Chinese students there make up the largest cohort of international students, there are fewer than 100 or so. Her mother had told her that 'it's safer to be silent,' she said, 'but I think it's also important for the American public to know that it's just unreasonable to make international Chinese students an imagined enemy.' She said she had planned to visit her family in China this summer but had decided against it after friends and professors advised her not to leave the country. The concern implied by the Trump administration that Chinese students might be here to conduct espionage or to work for the Chinese Communist Party baffled her. 'The majority of students are unrelated to all political matters,' she said. 'Most of us are from the Chinese middle class.' At the University of California, Berkeley, where more than 2,500 Chinese students are enrolled on student visas, Hongxian Zhang, a sophomore from Shanghai, said he had come to the United States because it had the world's best education system. His parents gave him some advice. 'Just follow the rules, be yourself, be a good person, don't offend any laws, and you'll be fine,' said Mr. Zhang, who is enrolled in global studies courses this summer. But the administration's announcement this week reminded him, unsettlingly, of the period during the Covid-19 pandemic when he lived in China and couldn't get access to websites from other countries because the Chinese government had blocked them. 'I can't say Trump is doing something bad, because he's looking out for his own country,' he said. 'I can understand that. But a country needs some interaction with the people outside your country, some international communication.' He said his previous impression of the country had been that 'America always accepts everything.' Watching the crackdown on international students unfold has been 'so weird,' he said. 'It's not like the US' At the University of California, Los Angeles, Tony, 19, a freshman who declined to share his last name because he feared retaliation, agreed. Sitting outside at a dining commons, the jacarandas like purple lace in the spring sunshine, he said that he had been drawn by the effortless beauty of Southern California and a professor he had met during a summer session. It had seemed a reward, he said, for the brutal intensity with which he had studied in China. But since his arrival, he said, the unpredictability of his status under the Trump administration has been a constant source of anxiety. 'I'm a person who worries about everything,' he said, 'and I can't stop thinking about it.' He said he had avoided talking about his visa fears with his parents, 'normal people' who don't have the same access to news that he does. But he can't escape the sense, he said, that he is now a bargaining chip in some larger negotiation. 'It seems like when they finished with the tariff thing, they turned to students,' he said. 'It's like a strategy.' Asked what he would tell Secretary Rubio or Mr. Trump, the teenager laughed wearily as students chattered around him, hearts light, minds sharp, plates overflowing with pizza and salad. 'First of all,' he said, 'I'm not a spy.'
