Autonomous warfare in Operation Sindoor
For Preliminary Examination: Current events of national and international significance
For Mains Examination: GS III - India's defence sector and acquisition
Context:
Launched in early May, in retaliation to the April 22 Pahalgam terror attack, Operation Sindoor marks a historic milestone, in which Unmanned Aerial Systems (UAS) played a primary role in direct military combat between two nuclear-armed neighbours, signalling an uncharted era of drone-centric warfare in South Asia
Read about:
Unmanned Aerial Systems (UAS)
Medium-Altitude Long-Endurance (MALE)
Key takeaways:
- In the 48 hours leading up to Operation Sindoor, Israeli Heron MK-II drones and India’s indigenously developed TAPAS-BH-201/Rustom-II Medium-Altitude Long-Endurance (MALE) Intelligence, Surveillance, and Reconnaissance (ISR) UAVs reportedly penetrated deep into Pakistani airspace. Their mission was to collect electronic and signals intelligence, as well as thermal data from suspected Islamist terror camps.
- Following the Indian Air Force's (IAF) strikes on nine targets inside Pakistan from May 7 onwards, both India and Pakistan deployed a wide range of unmanned aerial systems (UAS).
- These included ISR UAVs, armed drones, kamikaze loitering munitions, electronic decoys, and quadcopters, which served dual roles in real-time intelligence gathering and precision strikes. As the drone warfare escalated, both nations aimed to dominate the battlefield through continuous aerial surveillance, mapping enemy air defenses, missile sites, command centers, troop formations, and supply points.
- Decoy drones were frequently used to confuse radar systems, bait air defenses, and exhaust interceptor missiles, thereby reducing risks to manned aircraft. This intense drone conflict continued until a ceasefire was declared on May 10.
- During this period, India claimed to have shot down approximately 600 Pakistani drones, releasing intercepted videos and wreckage to substantiate its claims amid a high-stakes information war that paralleled physical confrontations.
- Pakistan countered by alleging that 300 to 400 Indian drones attempted strikes on its military and strategic assets but were intercepted before causing damage. India has neither confirmed nor denied these reports, citing the ongoing nature of Operation Sindoor.
- Open-source intelligence and drone tracking data revealed that India’s offensive utilized a diverse range of UAS, led by domestically developed loitering munitions such as the GPS-guided Nagastra-1 and Israeli-origin Harop drones, capable of autonomously targeting enemy radar systems.
- To overwhelm Pakistani defenses, India also deployed swarm drone formations co-developed by the Defence Research and Development Organisation (DRDO) and private companies.
- These swarms created radar clutter, provoked premature defensive reactions, and saturated surveillance networks. Priority targets included ammunition depots, Surface-to-Air Missile (SAM) sites, radar installations, and forward operating bases.
- The drone strikes were executed in well-planned waves. Initial sorties deployed decoy drones and electronic warfare systems to saturate radar coverage and provoke early, ineffective SAM launches.
- These were followed by precision loitering munitions and armed UAVs, guided in real time by Heron MK IIs and TAPAS-BH-201/Rustom-IIs. Quadcopters and micro-UAVs played a crucial role in providing live ISR feeds and target data through the Army’s Integrated Battle Management System (IBMS) to frontline units, enabling dynamic targeting and rapid response.
- Media reports suggested that India’s drone strikes caused disruption at a cricket match in Rawalpindi, forcing an evacuation due to air defense alerts. Another notable strike by a Harop drone reportedly destroyed a Chinese-supplied HQ-9 air defense system near Lahore, inflicting both psychological and strategic damage to Pakistan’s layered air defense network.
- Military analysts observed that India’s extensive use of diverse UAS to conduct calibrated cross-border strikes without risking manned aircraft represents a new regional model of deterrence. It also highlights India’s growing capabilities in autonomous, cost-effective, networked warfare, signaling a shift in aerial power dynamics in South Asia
Pakistan’s Response
- In retaliation, Pakistan launched Operation Bunyan-um-Marsoos (“Wall of Lead”), deploying various UAS including domestically developed Shahpar-II MALE UAVs, armed Burraq drones, Turkish Bayraktar TB2s, and Chinese CH-4 and Wing Loong II platforms.
- These were supplemented by Chinese CH-901 and WS-43 loitering munitions and indigenous kamikaze drones, striking multiple targets across a 1,500-kilometer stretch from Kashmir to Bhuj.
- The Shahpar-IIs, TB2s, and Wing Loong IIs mainly carried out ISR missions, streaming real-time imagery of Indian troop deployments, artillery, and logistics hubs. Meanwhile, Pakistan’s loitering munitions targeted radar sites, forward bases, and key Indian Army and Air Force command centers in northern and western sectors.
- However, these strikes were largely neutralized by India’s robust, multi-tiered air defense system, causing minimal damage.
- Strategic military and urban hubs such as Jammu, Pathankot, Amritsar, Bikaner, Jaisalmer, and Bhuj were frequently targeted. Despite the high intensity of these attacks, India’s integrated air defense network—which combines layered radar systems, SAM batteries, automated threat response, and upgraded legacy platforms—successfully mitigated damage and prevented significant disruption
India’s Multi-layered Air Defense
- Pakistan repeatedly attempted to overwhelm India’s Integrated Air Command and Control System (IACCS)—the nerve center of India’s air defense—by deploying drones along varied routes, altitudes, and timings to disrupt communications and forward command centers. However, these efforts largely failed.
- The IACCS integrates surveillance data from ground radars, airborne early warning aircraft, satellites, and other sensors into a centralized yet distributed command network.
- It coordinates with SAM systems and fighter jets to quickly detect, track, and intercept low-altitude threats, including drones. The system’s architecture allows it to maintain operations even if some nodes are damaged or jammed, by switching to alternate links and mobile radar units.
- Officials confirmed the IACCS remained largely intact throughout the conflict, with rapid recovery from any temporary disruptions. Its “mesh” design allowed seamless failovers, supported by satellite uplinks and mobile platforms maintaining continuous situational awareness.
- The system also demonstrated its Directed Energy Weapons (DEWs) capability, employing high-powered lasers or microwaves to detect, track, and neutralize airborne threats such as drones in real time.
- At the tactical level, the Akashteer (Sky Arrow) air defense control and reporting system, developed by Bharat Electronics Limited, provided a digital command interface for Army Air Defense units. It facilitated coordination between sensors and weapons, enabling rapid engagement of low-level threats like UAVs, even under electronic warfare conditions.
The Layered Defense Architecture
- India’s air defense architecture combined upgraded legacy Low-Level Air Defense (LLAD) systems with modern missile platforms, showcasing remarkable military innovation.
- Cold War-era systems such as the Pechora and OSA-AK SAMs, ZSU-23-4 Shilka, ZU-23-2 twin 23mm anti-aircraft guns, and L/70 Bofors 40mm guns were retrofitted with radar-directed targeting and electro-optical sights for close-in drone defense. Army and Border Security Force snipers also contributed by shooting down incoming drones in Jammu, Punjab, and Rajasthan.
- These older systems were supported by the Israeli SPYDER short- and medium-range missile system, employing Python-5 and Derby missiles for point defense against UAVs, cruise missiles, and aircraft.
- India’s indigenous Akash and Akash-NG (New Generation) missile systems provided medium-range defense, while the long-range Barak-8 missile system, developed jointly with Israel, protected high-value assets against aircraft, drones, and ballistic or cruise missiles.
- These systems were further backed by Russia’s advanced Almaz-Antey S-400 ‘Triumf’ surface-to-air missile system—renamed Sudarshan Chakra in India—with five units acquired for $5.5 billion since 2018, of which three have been delivered.
- All these assets were integrated through the IACCS, allowing coordinated, real-time response and comprehensive aerial threat management

A bow echo is a distinctive radar signature that appears as a curved or bow-shaped line of thunderstorms on weather radar displays. The name comes from its characteristic crescent or arc shape that resembles an archer's bow when viewed from above.
Key Characteristics
Radar Appearance The bow echo shows up on Doppler radar as a curved line of intense precipitation, typically 50-400 kilometers (30-250 miles) long. The center of the bow often shows weaker reflectivity due to strong downdrafts, while the edges maintain intense precipitation cores.
Structure Components
- Bookend vortices: Rotating circulations at each end of the bow
- Rear inflow jet: Strong winds flowing into the back of the storm system
- Weak echo region: An area of reduced precipitation in the center caused by downdrafts
- Forward flank downdraft: Descending air that creates surface wind damage
Formation Process
Bow echoes typically form when:
- A line of thunderstorms (squall line) develops asymmetric downdrafts
- Strong rear-to-front winds accelerate the center of the line forward
- The line bows outward, creating the characteristic curved shape
- Bookend vortices develop at the tips, helping maintain the structure
Meteorological Significance
Wind Production Bow echoes are primarily known for producing damaging straight-line winds at the surface, often reaching 60-100+ mph. These winds result from strong downdrafts that hit the ground and spread outward horizontally.
Storm Evolution They represent an intermediate stage between ordinary squall lines and more complex mesoscale convective systems. Some bow echoes can evolve into derechos when they persist and produce widespread wind damage over hundreds of miles.
Forecasting Importance The bow echo signature on radar is a critical warning sign for meteorologists, indicating that damaging winds are likely occurring or imminent, prompting the issuance of severe thunderstorm warnings.
1.Consider the following statements regarding Bow Echo:
- It appears as a curved or bow-shaped line of thunderstorms on weather radar displays.
- Bow echoes are primarily associated with rotating supercell thunderstorms that produce tornadoes.

The idea of Minimum Support Price (MSP) was initially introduced in the 1960s. At present, the government announces MSPs for 23 crops during every agricultural season. MSP represents the rate at which the government commits to purchasing a crop from farmers when its market price drops below a specified level. This ensures that farmers receive a guaranteed minimum income to cover their production costs and possibly earn a reasonable profit. MSPs also serve a strategic function by encouraging the growth of targeted crops, thereby maintaining a steady supply of essential food items across the country.
-
MSPs play a crucial role in influencing the broader pricing trends in agriculture, extending their impact beyond the specific crops for which they are officially set. While MSP decisions are made by the central government, they are primarily based on the recommendations of the Commission for Agricultural Costs and Prices (CACP).
-
The CACP considers several factors while advising on MSPs, including:
-
Demand and supply dynamics;
-
Production costs;
-
Price trends in domestic and global markets;
-
Price relationships among various crops;
-
The comparative value between the agricultural and non-agricultural sectors (i.e., input vs output prices);
-
A minimum profit margin of 50% over production costs;
-
And the potential impact of MSP on consumers.

In percentage terms, ragi witnessed the highest MSP increase of 13.89%, rising to ₹4,886 per quintal for the 2025–26 Kharif season, compared to ₹4,290 in the previous year. Similarly, jowar, another millet crop, also experienced an almost double-digit rise in its MSP.
-
The MSP for jowar (hybrid) has been fixed at ₹3,699 per quintal and ₹3,749 per quintal for jowar (Maldandi), reflecting an increase of around 10% from the previous season. Meanwhile, bajra’s MSP has gone up to ₹2,775 per quintal, a 5.71% hike over last season’s ₹2,625.
-
Recently, the government has emphasized the cultivation of millets, such as ragi and jowar, officially recognising them as ‘Shree Anna’. Although ragi accounts for a mere 0.51% of the nation’s gross cropped area, it is primarily grown in Karnataka, Tamil Nadu, and Maharashtra. Key producers of jowar include Maharashtra, Karnataka, Rajasthan, Tamil Nadu, and Uttar Pradesh.
-
The moong crop, a type of pulse, saw the smallest MSP increase of just 0.99%, going from ₹8,682 to ₹8,768 per quintal in the 2025–26 season. It is cultivated in Rajasthan, Maharashtra, Madhya Pradesh, and Karnataka.
-
Paddy, similar to moong, recorded a modest MSP hike. The MSP for paddy (common) has been set at ₹2,369 per quintal, and ₹2,389 per quintal for paddy (Grade A) — a 3% increase over the previous season. This limited rise is attributed to the surplus stock of rice already available in the Central Pool

Poverty refers to a situation where individuals or households lack sufficient financial means to secure a basic standard of living. Economists and policymakers typically measure absolute poverty as the gap between actual consumption levels and a defined threshold known as the poverty line. This line represents the minimum expenditure needed to acquire essential items included in the Poverty Line Basket (PLB). The extent of poverty is often expressed through the headcount ratio—the proportion of people living below this line. Meanwhile, the intensity or depth of poverty reflects how far individuals fall below the established threshold.
-
Over the years, six official panels have attempted to estimate poverty levels in India: the 1962 Working Group; V N Dandekar and N Rath in 1971; Y K Alagh in 1979; D T Lakdawala in 1993; Suresh Tendulkar in 2009; and C Rangarajan in 2014. However, the government has not officially adopted the Rangarajan Committee’s recommendations.
-
Recently, data from the Household Consumption Expenditure Surveys of 2022–23 and 2023–24 by the National Statistics Office (NSO) has enabled a new analysis of poverty and inequality. While several researchers have analysed data from the 2022–23 survey, few have yet used the 2023–24 data. These datasets allow observation of trends in poverty incidence, poverty depth, and income inequality from 2011–12 through 2023–24.
-
According to the Rangarajan methodology, the monthly poverty line (per capita consumption) in rural India was ₹972 in 2011–12, increasing to ₹1,837 in 2022–23 and ₹1,940 in 2023–24. For urban areas, the figures were ₹1,407 in 2011–12, ₹2,603 in 2022–23, and ₹2,736 in 2023–24. This translates to ₹13,680 per month for a five-member urban household in 2023–24. The combined poverty rate fell from 29.5% in 2011–12 to 9.5% in 2022–23, and further to 4.9% in 2023–24, marking a steady decline of around 2.05 percentage points per year—slightly lower than the 2.2-point annual reduction observed between 2004–05 and 2011–12.
-
A World Bank report titled Poverty & Equity Brief, covering over 100 developing countries, highlights that India has made substantial progress in reducing poverty. The share of the population living below the extreme poverty line (under $2.15/day at PPP) dropped from 16.2% in 2011–12 to 2.3% in 2022–23. This means more than 170 million people have escaped extreme poverty. Using the lower-middle-income threshold of $3.65/day, the poverty rate fell from 61.8% to 28.1% in the same timeframe.
-
A noticeable decline in poverty occurred between 2022–23 and 2023–24, from 9.5% to 4.9% in just one year. This sharp drop can be linked to multiple factors, including economic growth, inflation trends, and social safety net programs. India's GDP growth rose from 7.6% in 2022–23 to 9.2% in 2023–24, a 1.6 percentage point increase.
-
While the headcount ratio is a common metric, it is often critiqued for not reflecting the severity of poverty. Analysis shows that over half of the poor population lives within the third to fourth quartile of the poverty line, both in 2011–12 and 2022–23. Specifically, in 2022–23, 56% of the rural and overall poor belonged to this group. Likewise, many individuals categorized as non-poor are only slightly above the poverty threshold, falling within 115–125% of it
(a) poverty rates vary from State to State
(b) price levels vary from State to State
(c) Gross State Product varies from State to State
(d) quality of public distribution varies from State to State
|
Answer (b)
The official poverty line in India is determined based on the consumption expenditure required to meet minimum calorie intake and basic non-food needs. Since prices of goods and services vary across states, the amount of money needed to purchase the same "poverty line basket" of goods differs. Therefore, poverty lines are adjusted for inter-state price differences, resulting in higher poverty lines in states where cost of living is higher. Other options, though related to economic conditions, do not directly influence the calculation of the poverty line:

Overview of the POCSO Act and a Controversial Judicial Development
- The Protection of Children from Sexual Offences (POCSO) Act, enacted in December 2012, criminalizes both penetrative and non-penetrative forms of sexual assault, sexual harassment, and child pornography.
- As a gender-neutral statute, it considers all individuals below 18 years as legally incapable of providing consent. The law mandates child-sensitive procedures, including the establishment of special courts, closed-door trials, and the use of video-recorded statements.
- With provisions for stringent punishment, a presumption of guilt against the accused, and time-bound trials, the Act was intended to address significant gaps in child protection legislation and ensure prompt, victim-centered justice.
The West Bengal Case
- In a case from rural West Bengal, a 13-year-old girl was reported missing by her mother in May 2018. She was later discovered to have been living with and married to a 25-year-old man, with whom she had a child.
- Despite her mother’s attempts to rescue her, the girl remained with the man. Following an FIR filed by her mother, a special court in September 2022 convicted the accused under various provisions of the POCSO Act and the Indian Penal Code—specifically Sections 363 (kidnapping), 366 (abduction to compel marriage), 376(2)(n) (repeated rape of the same woman), and 376(3) (rape of a girl under 16)—sentencing him to 20 years in prison.
Calcutta High Court's Intervention
- However, the Calcutta High Court overturned the conviction using its inherent authority under Section 482 of the Criminal Procedure Code. This decision conflicted with POCSO's clear stance that sexual acts involving minors cannot be considered consensual.
- The High Court even suggested that consensual relationships involving adolescents should be excluded from POCSO’s scope.
- It delved into the topic of adolescent sexuality, attributing it to factors such as early puberty, changing diets, climate change, and increased exposure to social media and pornography.
- This line of reasoning, lacking empirical support, ignored broader societal and structural issues while reinforcing regressive gender roles.
Supreme Court’s Response
- On August 20, 2024, the Supreme Court, acting suo motu, nullified the High Court’s judgment. It reaffirmed that the POCSO Act does not validate consensual sexual relationships involving minors, and warned against diluting its core objective.
- The apex court also criticized the High Court for straying from legal analysis and engaging in speculative social commentary.
- Nevertheless, it postponed sentencing, seeking an expert report from a three-member panel that met the victim and assessed her situation.
Findings and Recommendations
- The expert committee reported that the girl now lives in poverty, in temporary housing, and remains emotionally attached to the accused. She faces intense societal and legal challenges in her efforts to secure his release.
- The report described the implementation of POCSO in this case as a systemic failure and recommended that, for the child’s well-being, the family unit should be preserved. It also called for coordinated support—legal, financial, and educational—for the victim.
- Quoting the report, the Supreme Court noted, “Society judged her, the legal system failed her, and her own family abandoned her.”
- Exercising its extraordinary powers under Article 142 of the Constitution, the Court withheld sentencing and directed the West Bengal government to ensure her rehabilitation and welfare.
Broader Implications
- This case highlights a dangerous departure from the principles of child protection enshrined in the POCSO Act.
- The Supreme Court emphasised that such deviations should not set a legal precedent, warning that they could undermine the law’s primary goal of safeguarding children from sexual abuse.
- Allowing exceptions in the name of family preservation may create loopholes for offenders to exploit vulnerable minors.
- The case also underscores the urgent need for age-appropriate sex education and a curriculum free of stigma and moral judgment
|
Answer (A)
The Protection of Children from Sexual Offences (POCSO) Act, 2012 was enacted to provide a robust legal framework for the protection of children (below 18 years) from sexual abuse, sexual harassment, and pornography. It is a gender-neutral law and incorporates child-friendly procedures to ensure the child’s safety during judicial proceedings. |
