Need to extend surveillance envelope: Air Marshal Dixit
New Delhi, Modern warfare has "fundamentally altered" the relationship between distance and vulnerability, and there is a need to "extend our surveillance envelope" to detect potential threats much before they approach the border, a top military officer said on Wednesday.
In his address at an event held at Subroto Park, Chief of Integrated Defence Staff, Air Marshal Ashutosh Dixit also asserted that Operation Sindoor demonstrated that indigenous innovation, when properly harnessed, can "match and even exceed" international benchmarks.
The domain of surveillance and EO system has evolved. It was a "force enhancer", now it is slowly becoming a foundation upon which modern military operations will take place, he said.
"I have witnessed this transformation first-hand throughout my career. And, today, we stand at a cusp of a revolution that will define how we perceive, process and project power, in the 21st century," Air Marshal Dixit said.
He emphasised that the recent months have provided "compelling evidence" of the same.
In his address, he laid stress on the critical importance of "deep surveillance" in contemporary warfare.
The lessons of Operation Sindoor, what military strategist have perhaps not fully appreciated until now is that "modern warfare thanks to technology has fundamentally altered the relationship between distance and vulnerability," the officer said.
It has given a new meaning to simultaneity and non-linearity. Earlier, the horizon marked the limit of immediate threat. Today, precision-guided munitions, like SCALP, BrahMos, etc, have "rendered geographical barriers almost meaningless", as strikes with air-to-air missiles and supersonic air-to-ground missiles have become commonplace, he said.
India used long-range weapon systems and platforms to strike deep within the Pakistan territory to destroy terror infrastructure during Operation Sindoor.
Air Marshal Dixit said when weapons can strike targets hundreds of kilometres away with pin-point accuracy, "the traditional concepts of front, rear, and flanks, combat zones, depth areas, all become irrelevant. What we call the front and the theatre, merge into one".
He emphasised that this "new reality" demands that "we extend our surveillance envelope far beyond what previous generations could have even imagined".
"We must detect, identify and track potential threats not when they approach our border, but when they are still in their staging areas, airfields, bases and deep within their own territory," the top officer said.
This existed as a concept earlier, but today "we have the means" to realise it, he added.
Compressed timelines of modern warfare, amplify this need.
"When hypersonic missiles can traverse hundreds of kilometres in mere minutes and drone swarms can reach their targets before traditional decision-making processes can respond, real-time or near real-time surveillance becomes not just advantageous but essentially for surviving," he said.
The speed of modern weapons has fundamentally altered the OODA loop, compressing it from hours to minutes, and sometimes even seconds, the officer said.
This new reality is being shaped by small satellite constellations that are revolutionising battlefield awareness. The fusion of electro-optical, and other capabilities now enable a "24x7 dynamic persistence and predictive mosaic" of the battlefield.
"We no longer merely observe, we anticipate, predict and pre-empt," he said.
The precision that defines modern weapon systems, however, comes with its own challenges, the officer cautioned.
"While it offers an unprecedented capability to strike with minimal collateral damage, it also demands intelligence in equal precision. Outdated or inaccurate data doesn't merely reduce effectiveness, it can lead to mission failures, unintended casualties and strategic setbacks that reverberate far beyond the immediate battlefield," he said.
In his address, he also referred to China's military space programme, which he said has expanded from "operating just 36 satellites in 2010 to over a thousand by 2024, with more than 360 dedicated to ISR missions".
ISR refers to intelligence, surveillance and reconnaissance.
"As we contemplate our own surveillance capabilities, we must understand the rapidly evolving threat landscape, particularly the remarkable advances made by our neighbours to the north," he said.
The officer said Chinese satellites have recently demonstrated "sophisticated dog-fighting manoeuvres" in lower earth orbits.
"They have evolved from a kill chain to a kill mesh, an integrated network that seamlessly interweaves ISR satellites with weapon systems," he added.
The top officer also cited cases of conflicts that have occurred in the recent years, from Armenia-Ajerbaijan conflict to Russia-Ukraine war, Israel-Hamas, and Indian's own experience in the recent Operation Sindoor.
"What truth emerges with crystal clarity, the side that sees first, sees farthest, and sees most accurately prevails," he underlined.
This axiom has guided military thinking for centuries and has has become even relevant in the current precision warfare and multi-domain operations, the officer said.
The tri-Services officer was speaking at a seminar on 'Surveillance and Electro-optics' hosted by think-tank CS and Indian Military Reviews .

Shashi Tharoor Calls PM Modi "Prime Asset For India" In New Provocation For Congress
New Delhi: Congress MP Shashi Tharoor - who led the ruling BJP's anti-terrorism diplomatic outreach to the United States, Brazil, and three other nations last month, after Operation Sindoor - has called for more support for Prime Minister Narendra Modi's "energy, dynamism and willingness to engage (with other countries)" and labelled it "a prime asset for India on the global stage". In an article published by The Hindu (paywalled) Monday morning, Mr Tharoor said the outreach - seven cross-party MP delegations visited 32 countries, including the US, the European Union and member nations, Saudi Arabia, and Russia - was "a moment of national resolve and effective communication (and) affirmed that India, when united, can project its voice with clarity and conviction..." He said the delegations explained the "calibrated and measured" nature of India's military response to the Pahalgam terror attack, underscored Pakistan's continued links to terrorism. He specifically referenced the crossover of Indian and Pak delegations in the US and said, "Even as a Pakistani delegation was simultaneously present, we found US representatives... echoing our concerns and urging decisive action against terror groups... our arguments, grounded in facts and consistent advocacy, were reinforcing the legitimacy of India's position." "We consistently highlighted the severity of the threat from across our borders, aiming to build global consensus to hold perpetrators accountable," he wrote, calling the outreach a success. Mr Tharoor was one a dozen opposition leaders who were part of these delegations; the list included high-profile figures like Mr Tharoor and others from the Congress, as well as AIMIM chief Asaduddin Owaisi, the Shiv Sena (UBT)'s Priyanka Chaturvedi, the DMK's Kanimozhi. The Thiruvananthapuram MP's selection increased friction between himself and his party; the two already have a frosty relationship over several issues, including continuing positive words for the PM. That friction has led to talk of a blockbuster political switch, i.e., the four-time Lok Sabha MP, who was also a former top United Nations official and a former External Affairs Minister, was preparing to jump from the Congress to Mr Modi's side. In fact, after news of his appointment to lead the US-bound delegation, arguably the most important of the seven, sections of the Congress called him a 'super spokesperson' for the BJP's 'publicity stunts' and accused of flattering Prime Minister Modi. However, Mr Tharoor has repeatedly dismissed talk of a switch, insisting he could not swap the Congress for the BJP. Speaking to NDTV last week he again played down any friction with the party, calling such incidents "differences of opinion... with only some elements of leadership". When NDTV asked him how he would define his relationship with the Congress today, Mr Tharoor pointed out he had been loyal to the party and its ideology for the last 16 years.

Shashi Tharoor calls for 'greater backing' of PM Modi's energy, dynamism: ‘Prime asset'
Congress leader Shashi Tharoor has heaped big praise on Prime Minister Narendra Modi, calling his energy and dynamism an asset for India. His remarks came days after the Operation Sindoor delegations, one of which Tharoor led, came back after representing India overseas. Prime Minister Narendra Modi greets Congress MP Shashi Tharoor as he meets members of the seven multi-party delegations at his residence in Delhi on Tuesday. (PTI)(HT_PRINT) In a news article with an English daily, Tharoor wrote at length about his takeaways from leading such a delegation, representing India's stance against terrorism. "Prime Minister Narendra Modi's energy, dynamism and willingness to engage remains a prime asset for India on the global stage, but deserves greater backing," he wrote in The Hindu article. Tharoor, who led the Indian delegation to the United States, Panama, Guyana, Colombia, and Brazil, termed Operation Sindoor "a moment of national resolve". He also emphasised the value of unity as a nation and of public diplomacy. He also highlighted his engagement in the Washington DC and said that US officials recognised India's concerns, even in the presence of Pakistani representatives. "Even as a Pakistani delegation was simultaneously present, we found US representatives, including those who met the Pakistani officials, echoing our concerns and urging decisive action against terror groups such as the Lashkar-e-Taiba and Jaish-e-Mohammed," Tharoor wrote. As part of the Operation Sindoor outreach, members cutting across party lines travelled to 32 countries to put forth India's resolve to tackle terrorism amid tensions with Pakistan following the April 22 Pahalgam terror attack. Shashi Tharoor had drawn criticism from Congress after being chosen to lead the Operation Sindoor delegation, as he was not among the names formally recommended by the party to be included in the delegations. 'BJP's super spokesperson' After Tharoor praised the 2015 Uri strike during his Panama leg and said that India never crossed the Line of Control before that, Congress leader Udit Raj termed him "BJP's super spokesperson", further escalating Congress's internal rift. "My dear Shashi Tharoor, Alas! I could prevail upon PM Modi to declare you as super spokesperson of BJP, even declaring (you) as foreign minister before landing in India. How could you denigrate the golden history of Congress by saying that before PM Modi, India never crossed LoC and International border." This post by Udit Raj was also reshared by Congress MP Jairam Ramesh on X. Reacting to the controversy, Shashi Tharoor had said he cannot dwell on the criticism. "'Undoubtedly, in a thriving democracy, there are bound to be comments, criticisms. But I think at this point, we can't afford to dwell on it, when we get back to India, no doubt we have a chance to speak to our colleagues, critics, and media there," Tharoor had said.

Defence Stocks Fire Up On Escalating West Asia Tensions; Paras Defence, BEL Gain Up To 5%
Last Updated: Defence Stocks Rally: Shares of defence companies surged on June 23 after the US launched strikes on key Iranian nuclear facilities Defence Stocks Rally: Shares of defence companies surged on June 23 after the US launched strikes on key Iranian nuclear facilities, heightening tensions in the Middle East and fuelling expectations of increased defence spending globally. The Nifty Defence index rose nearly 1.7% to hover around 9,037 in morning trade. Zen Technologies and Paras Defence were the top performers, rising up to 5% and trading at around Rs 1,995 and Rs 1,718, respectively. Zen Tech was locked in its upper circuit. Other notable gainers included Astra Microwave, Bharat Electronics (BEL), Garden Reach Shipbuilders (GRSE), and Data Patterns — each gaining over 2%. Mazagon Dock rose nearly 2%, while Cochin Shipyard and DCX India added over 1.5% each. BEL also emerged as the top gainer on the Sensex. Hindustan Aeronautics (HAL), Bharat Dynamics (BDL), and BEML traded with modest gains, while Solar Industries bucked the trend with marginal losses. Meanwhile, drone-tech firm IdeaForge hit the upper circuit with a 10% rally to Rs 631.05. The rally came after former US President Donald Trump announced a successful strike on three of Iran's main nuclear enrichment sites. In a televised address, Trump claimed the facilities had been 'completely obliterated" using bunker-buster bombs and Tomahawk missiles, while also warning Iran of further action if a peace deal is not reached. Israeli Prime Minister Benjamin Netanyahu hailed the move, calling it a 'bold decision" to deny nuclear weapons to a dangerous regime. Though US officials clarified that Washington is not at war with Tehran, the heightened rhetoric added to global market volatility. Indian defence stocks have already been in focus in recent months. In May, India carried out cross-border strikes under 'Operation Sindoor' against terror outfits in Pakistan, boosting investor interest in the sector. The ongoing Russia-Ukraine war has further supported sentiment toward defence plays. However, analysts remain divided. While some expect strong order inflows to continue, others caution that current valuations in the sector may be running ahead of fundamentals. 'Defence stocks have been highly volatile lately, rallying strongly after Operation Sindoor, then seeing profit booking, and now rising again amid Middle East tensions. This reflects a mix of short-term momentum and long-term optimism. Geopolitical risks and a stronger push for domestic defence manufacturing have boosted investor confidence. With India's defence spending at just 1.9% of GDP, there's significant room for long-term growth," said Ajit Mishra, SVP, Research, Religare Broking. 'However, the sharp rally has brought valuation concerns, making near-term volatility likely. Investors should remain selective, focusing on companies with robust order books, sound financials, and strong execution. While the momentum may fluctuate, the long-term outlook for India's defence sector remains structurally attractive in an increasingly uncertain global landscape," he added. Sankhanath Bandyopadhyay, Economist at Infomerics Valuation and Ratings, meanwhile, said, 'Defence stocks look promising due to the ongoing geopolitical tussle between Iran and Israel. Moreover, the Indian government is likely to enhance defence spending from the current ~2 per cent of GDP to 3–4 per cent over the next decade. Further, the government has targeted Rs 25,000 crore in defence exports by 2025–26." He added, 'Investors can focus on export-driven defence stocks with long-term potential. In the current scenario, geopolitical tensions will likely be lingering between different countries, especially as being reflected in rising tensions in the Middle East. Investors should carefully assess the financials and outlook of such stocks before investing, and there should be a judicious mix so that a healthy dividend can also be earned."
