WHAT IS A BUNKER BUSTER?
A 'bunker buster' missile is a specialised weapon designed to penetrate and destroy heavily fortified underground targets such as military bunkers, command centers, missile silos, and storage facilities.advertisementUnlike conventional warheads that explode on or near the surface, bunker busters are engineered to burrow deep into the ground or through reinforced concrete before detonating, maximising their destructive effect against hardened or subterranean structures.HOW DO BUNKER BUSTER MISSILES WORK?Bunker buster missiles achieve penetration through a combination of high mass, hardened casings, and advanced guidance systems.Upon impact, the missile's hardened nose and dense construction allow it to pierce several meters of reinforced concrete or earth. Once it reaches the desired depth, a delayed-action fuse triggers the warhead, creating a shockwave that collapses the target from within. The new variant of India's Agni-5 missile, under development by the DRDO, is reported to carry a massive 7,500-kilogram conventional warhead — one of the largest bunker-buster payloads globally. This gives it the capability to destroy even the most deeply buried and heavily protected enemy assets.COMBAT ROLE AND STRATEGIC IMPORTANCEBunker buster missiles play a crucial role in modern warfare, especially in scenarios where adversaries rely on underground facilities for protection and command.Their primary combat roles include:Neutralising Command and Control Centers: Disabling enemy leadership and communication hubs hidden underground.Destroying Missile Silos: Preventing the launch of ballistic or cruise missiles by targeting their protected launch sites.Eliminating Weapons Storage: Striking underground depots containing ammunition, fuel, or chemical/biological weapons.Suppressing Air Defense Systems: Targeting deeply buried radar and control facilities that support enemy air defenses.POTENTIAL APPLICATIONS FOR INDIAadvertisementIndia faces unique security challenges along its borders with both Pakistan and China, where adversaries have invested heavily in underground bunkers, missile silos, and command posts.

The Agni-5 bunker buster variant could serve several strategic and tactical purposes:Targeting Hardened Military Installations: Both Pakistan and China maintain fortified command centers and ammunition depots near the border. The missile could neutralise these assets in a conflict.Counterforce Operations: In the event of hostilities, India could use bunker busters to preemptively destroy enemy missile silos or nuclear storage sites, reducing the risk of retaliation.Deterring Underground Infrastructure: The mere possession of such a capability could deter adversaries from relying on underground facilities, shifting the strategic balance.Mountain Warfare: In the Himalayas, where terrain favours tunnelling and underground bunkers, such missiles would give India a decisive advantage.- EndsTune InMust Watch

Institution of Dalai Lama to continue, Tibetan trust to decide successor
Reaffirming that the 600-year-old institution of the Dalai Lama will continue, the exiled Tibetan spiritual leader on Wednesday announced that the Gaden Phodrang Trust would decide on his successor. Tibetan spiritual leader the Dalai Lama speaks in a video broadcast at the start of the 15th Tibetan Religious Conference, a meeting of religious leaders in McLeodganj, near Dharamsala on Wednesday. Exiled Tibetan spiritual leader the Dalai Lama said on July 2, that the 600-year-old institution will continue after his death, a decision that will have profound impact on his Buddhist followers. (AFP Photo) The 14th Dalai Lama made the significant announcement of his successor at the 15th Tibetan religious conference that began at McLeodganj near Dharamshala in Himachal Pradesh ahead of his 90th birthday on July 6. The conference is being attended by leaders and representatives of all major Tibetan Buddhist traditions. The spiritual leader reiterated that the responsibility for recognising the 15th Dalai Lama would rest exclusively with the Trust. 'Though I have had no public discussions on this issue over the last 14 years, leaders of Tibet's spiritual traditions, members of the Tibetan Parliament in Exile, participants in a special general body meeting, members of the Central Tibetan Administration, NGOs, Buddhists from the Himalayan region, Mongolia, Buddhist republics of the Russian Federation and Buddhists in Asia, including mainland China, have written to me with reasons, earnestly requesting that the institution of the Dalai Lama continue. In particular, I have received messages through various channels from Tibetans in Tibet making the same appeal. In accordance with all these requests, I am affirming that the institution of the Dalai Lama will continue,' the Dalai Lama said in his statement. The spiritual leader, who was recognised as the reincarnation of his predecessor at the age of two and has been living in exile in Dharamshala for 66 years, had in 2011 said that he would speak on the matter (reincarnation) when he reached the age of 90. He said, 'The process by which a future Dalai Lama is to be recognised has been clearly established in the September 24, 2011, statement which states that responsibility for doing so will rest exclusively with members of the Gaden Phodrang Trust, the office of His Holiness the Dalai Lama. They should consult the various heads of the Tibetan Buddhist traditions and the reliable oath-bound Dharma Protectors who are linked inseparably to the lineage of the Dalai Lamas. They should accordingly carry out the procedures of search and recognition in accordance with past tradition.' Rejecting any interference by China in naming the next Dalai Lama, he said: 'I hereby reiterate that the Gaden Phodrang Trust has sole authority to recognise the future reincarnation; no one else has any such authority to interfere in this matter.' The process of recognising the reincarnations of lamas in Tibetan Buddhism is solely and uniquely a Tibetan religious tradition. In contrast, China maintains that the process of selecting his successor must adhere to Chinese law, asserting its control over Tibetan Buddhism and rejecting any succession beyond its authority. In 1959, the Dalai Lama, then 23-year-old Tenzin Gyatso, fled to Dharamshala with thousands of Tibetans following a failed uprising against Mao Zedong's Communist rule, which gained control of Tibet in 1950.

China can't choose: Dalai Lama plans to reincarnate - will be reborn abroad
NEW DELHI: Exiled the said on Wednesday that the 600-year-old institution will continue after his death, a move likely to deeply influence his global Buddhist followers. Speaking during prayer celebrations ahead of his 90th birthday, the Dalai Lama reaffirmed that the institution he leads will endure beyond his lifetime. Tired of too many ads? go ad free now In a recorded message, the Nobel Peace Prize-winning spiritual head of Tibetan Buddhism said his successor should be identified in keeping with centuries-old Buddhist traditions. Tibetan Buddhists believe that the Dalai Lama chooses the body into which he is reincarnated, a process that has occurred 14 times since the institution's founding in 1587. The Dalai Lama said that responsibility for identifying the 15th Dalai Lama "will rest exclusively" with the India-based Gaden Phodrang Trust, the office of the Dalai Lama, according to news agency AFP. "I hereby reiterate that the Gaden Phodrang Trust has sole authority to recognise the future reincarnation; no one else has any such authority to interfere in this matter," he added. Tenzin Gyatso was recognised as the 14th Dalai Lama in 1940. He fled Tibet in 1959 after Chinese forces crushed an uprising in Lhasa and has lived in exile in Dharamshala, India, ever since. The Dalai Lama has long maintained that his successor will be born outside of China, a stance that directly challenges Beijing's claim that it alone has the authority to appoint the next Dalai Lama. China considers him a separatist and rejects any religious process outside its control. Reaffirming his position, the Dalai Lama said, 'The institution of the Dalai Lama will continue,' and stated that the search for his reincarnation must follow 'past tradition.' Most Tibetan Buddhists, both inside Tibet and in exile, strongly oppose China's efforts to control Tibetan religious affairs.

India needs foreign parts for Tejas. Defence atmanirbharta can't become a weakness
India's pursuit of self-reliance in defence aviation, especially in the field of domestic jet fighter production, is a saga of ambition and innovation. It is also a tale of bureaucratic bungling, lack of accountability, and the absence of inter-department coordination. We tend to make the same mistakes over and over again. Surprisingly, the A tmanirbharta Ayatollahs of social media, otherwise quick to assign monikers like 'Import Bahadur' to any veteran or journalist who makes the case for importing necessary tech until we can make it domestically, have been silent on the decision. Hindustan Aeronautics Limited's decision not to equip the Tejas Mk1A aircraft with the indigenous Uttam AESA radar and Swayam Raksha Kavach electronic warfare suite—made by the Defence Research and Development Organisation—preferring instead the Israeli ELTA systems, has sparked significant debate. For the domestic defence industry, the template remains unchanged: overpromise, underdeliver, blame the delays on external factors, and then accuse the forces of not being supportive of domestic programmes. Different aircraft, same story India was the first Asian country to domestically design and produce a modern jet fighter aircraft. On 24 June 1961, HF-24 Marut undertook its first flight; barely five years after the programme approval and only 14 years after Independence. It was a tremendous achievement. However, what could have been a stupendous base for the development of India's domestic defence aviation industry fizzled out in a damp squib. In 2025, we find ourselves at the cusp of greatness again, in the form of the Light Combat Aircraft (LCA) Tejas programme. The challenges remain the same: financial, technological, institutional, and political. And we're repeating some of the old mistakes. Both HF-24 Marut and the Tejas—its modern successor—aimed to equip the Indian Air Force (IAF) with homegrown combat aircraft. Despite great potential, the former failed to deliver, and the latter is muddling along. Also read: Pakistan suffers violence of its own making. West's refusal to learn is even more tragic Marut vs Tejas The HF-24 Marut, developed by Hindustan Aeronautics Limited (HAL), was a pivotal achievement. A relatively poor Asian country had pulled off an engineering miracle. Led by German designer Kurt Tank and later Dr Raj Mahindra, it was an ambitious programme. Incidentally, Tank was the lead designer of the legendary Focke-Wulf 190, the German single-engine fighter of World War 2. India's recruitment of Tank in the 1950s was a strategic effort driven by Prime Minister Nehru and shepherded by defence minister VK Krishna Menon. At the time, Tank was working on the design of the FMA IAe 33 Pulqui II, one of Latin America's first jet fighters. But political instability and economic challenges under Juan Perón's regime made Tank consider other opportunities. India capitalised on the development, offering him a stable job and an ambitious project. The IAF's air staff quality requirements (ASQR) were ambitious too. It wanted Marut to achieve 1.5 Mach initially and 2 Mach eventually. It was intended to be a supersonic, multi-role fighter for ground attack as well as air superiority roles, with a combat radius of at least 500 miles. The programme tasted initial success, and the first production aircraft was delivered to the IAF on 1 April 1967. The first challenge was also felt early on, as it was observed that the aircraft was grossly underpowered. The Bristol Siddeley Orpheus 703 engine could provide only 4,850 lbs of thrust, barely adequate to reach 0.95 Mach, well below the intended target. The aircraft could not achieve supersonic speed. This deficiency in the engine was well known, but it happened to be the only one readily available. Orpheus 703 was also used in the British aircraft Folland Gnat and was being license-produced by HAL in India. Tank was not happy with this selection and reluctantly agreed to its use as an interim solution due to India's limited technological and financial resources. Tank wanted an uprated Bristol BOr12 Orpheus afterburning turbojet engine that could produce 8,150 lbs of thrust, to power his twin-engine, swept-wing fighter. Unfortunately, New Delhi was unwilling to invest £13 million in the customised engine. Alternatives were few and far between. Engine options from Russia, the US, Britain, and even Egypt were considered, but the geopolitical situation for India at the time was precarious. The recent war with China, disappointment from the Non-Alignment Movement (NAM), increasing differences with the US, and growing closeness to the USSR—all these developments played a role. The options were unsuitable either financially, technically or geopolitically. Eventually, IAF was forced to make do with a non-afterburning Orpheus 703 engine on the HF 24. By the time it entered service in 1967, Marut was considered close to obsolescence. It could not keep up with supersonic fighters of that era—Indian MiG-21s or Pakistani F-104 Starfighters. The IAF shelved plans for upgrading Marut with radar and air-to-air missile capabilities, and relegated the jet to ground attack roles. Proposals for advanced variants like the HF-71 and HF-72 were abandoned, and the programme ended in the 1980s after producing only 147 aircraft. In comparison, the LCA Tejas has had a long timeline from conception to deployment. Initiated in 1983, the programme achieved its first flight only in January 2001. It took another 18 years to achieve Final Operational Clearance (FOC). The first squadron was raised on 27 May 2020 with only four serial production FOC aircraft. So far, 38 aircraft have been delivered to the IAF, out of the 83 on order. Plans for an additional 97 Mk1A/B and nearly 200 LCA Mk2 are at various stages of approvals. The first batch of LCA Mk1A was to be delivered to the IAF in March 2024; none has been delivered to date. Also read: Trump has driven up NATO's defence spending. Why that's good for India Achilles' heel Like the Marut, the aeroengine is proving to be the Achilles' heel for LCA. For the Marut, several engine options were explored by HAL. Besides evaluating the Soviet-made Klimov K-7 and RD-9F engines, the option to collaborate with Egypt on the development of the EL-300 engine was also considered. The Soviet engines were found incompatible with the Marut's airframe, and Egypt gave up on EL-300 after the 1967 Arab-Israeli War. The proposal from Rolls-Royce to further develop the Orpheus for the Marut was rejected by the Indian government, likely due to cost and political considerations. The Gas Turbine Research Establishment (GTRE), a lab under India's Defence Research and Development Organisation, was also tasked with enhancing the performance of the Orpheus 703 engine. The GTRE attempted to build an afterburning (reheated) version of the Orpheus 703. However, the programme failed to deliver the desired outcomes. On similar lines, the Tejas was intended to be powered by the indigenous Kaveri engine, but its development faced setbacks. Unable to meet performance targets of weight and thrust, the Kaveri was sidelined in favour of imported engines. The GE F404 engine, meant only as a stopgap arrangement for the early variants, has now become the mainstay. At the moment, India is incapable of avoiding reliance on foreign engines. Supply delays from GE are causing inordinate delays in the production of LCA Mk1A. Hopefully, lessons will be learned and HAL will secure the supplies of GE 404 and GE 414 engines in sufficient numbers for the upcoming production targets. Another issue that raises questions on our ability to absorb technology has been in the field of engine manufacturing. Despite license-producing various jet engines such as Orpheus 703, Tumansky R-25, Rolls-Royce Adour, AL-31FP, and AL-55I, we have not been able to master the technology adequately enough to fix the flaws in Kaveri. Also read: Chinese J-20 isn't just a fighter jet—it's a signal to US, Japan and India Operational performance Despite bad programme management, both Tejas and Marut turned out to be reasonably good in operations. The HF-24 Marut was operational in three IAF squadrons in 1971: Number 10 (Winged Daggers), 31 (Lions), and 220 (Desert Tigers). These squadrons saw significant action during the 1971 India-Pakistan War, flying about 200 missions. Three aircraft were lost in the air, and one was lost on the ground. Squadron Leader KK Bakshi, while flying a Marut, shot down a Pakistani F-86 Sabre on 7 December. Marut was much liked by the pilots, as it had a spacious and well-laid-out cockpit, and was easy to handle at low levels. Since it was built tough, it could survive several hits from ground fire. On account of two engines with redundant systems, it also had better survivability against bird ingestion and system failure. The details of LCA's performance in Operation Sindoor are not available in the open domain. However, Tejas has consistently performed well in air exercises like Gagan Shakti, fire power demonstrations, Akraman, Trishul, and so on. The most stellar thing about LCA Tejas has been its flight safety record in the development phase. It did not suffer even a single catastrophic failure in the testing and development phase, which is unheard of in the case of a single-engine fighter programme anywhere in the world. Also read: Asim Munir is playing good jihadi-bad jihadi game. Suicide bombing shows he's failing IAF's role The IAF is often accused of lacking enthusiasm for domestic programmes and placing greater reliance on imported equipment. This presumption stems from ignorance about how the IAF draws out its ASQRs and how the defence ministry sanctions capital procurements. The IAF lists out quality requirements (QRs) based on existing and evolving aerial threats. On the other hand, the decision about whether to procure particular equipment (or not) is made by the government. Whether to source this equipment from the local market or procure it globally is another decision the government makes. It has the final say on ASQRs as well, and has the right to modify QRs to enable domestic industry participation. Once the equipment and vendor are finalised, the quantity and the delivery dates are inked in the contract. The threats are not static, and the enemy has a vote. As the delivery timelines slip by, the threats evolve on account of the emergence of new technology and new acquisitions by the adversary. The IAF would want the equipment to be the latest on the day it is fielded in an operational unit and not on the day it was ordered. The threat is not static—the ASQR shouldn't be either. The Marut faced deficiencies in operational performance due to engine issues, while the Tejas took nearly 20 years from first flight to the FOC. For the Marut, the IAF's initial excitement waned due to its subsonic performance and engine limitations, leading to a preference for the Jaguar. Tejas faces similar IAF scepticism, with concerns about its performance, delivery delays, and the reliance on foreign components. There is also a growing concern that with China making great progress in the field of aeroengines, aerial weapons, and fighter aircraft development, future variants of Tejas could be obsolete even before they enter squadron service. China, the primary adversary for India, has fielded two variants of fifth-generation fighters, J-20 and J-35. It also has reportedly fast-tracked sixth-generation fighters such as J-36 and J-50. There are reports that Pakistan will soon be receiving J-35 fighters from China. In that environment, Tejas Mk1A and Tejas Mk2, which are 4.5 generation aircraft and are yet to enter squadron service in the IAF, would find it difficult to hold ground in an aerial encounter. The threats are evolving rapidly, so the demands from the services would evolve too. It would be foolhardy to assume that the IAF would not revise ASQRs as the deliveries are delayed and newer, more potent threats emerge. The bottom line remains unchanged. The onus of equipping the IAF and other services is on the government. Delays cause capability degradation, therefore the government must seek accountability from weapon suppliers, whether foreign or domestic.
