The Defence Research and Development Organisation confirmed completion of final development trials of the Universally Compatible Laser Guided Missile Version 3, a domestically developed air-to-ground and air-to-air missile system.

• Dual-channel HD seeker: the guidance head uses two independent channels for laser tracking, improving target lock accuracy and reducing the risk of decoy countermeasures defeating the guidance.
• Two-way data link: allows the launch platform to update targeting parameters after the missile is in flight and to receive data from the missile, enabling mid-course corrections.
• Warhead options: the missile can be fitted with an anti-armour warhead, a penetration-cum-blast warhead for hardened structures, or a pre-fragmentation warhead for soft targets and personnel. Modularity reduces the need for separate weapon programmes.
• Modes: air-to-ground primary role; the air-to-air mode gives UAV operators a self-defence capability, which is unusual for laser-guided missiles in this class.
• Developed by Research Centre Imarat: RCI is DRDO's premier missile research laboratory based in Hyderabad. It is responsible for guidance and control technology across India's missile inventory, including seekers for BrahMos and Astra.
• Platform: integrated on Newspace UAVs, reflecting DRDO's push to arm indigenous drone platforms with precision weapons.

Research Centre Imarat also announced the maiden flight trial of TARA (Tactical Autonomous Rifle-launched Aerial munition, or as publicly named, a tactical glide weapon), a modular kit that converts unguided warheads into precision-guided munitions.

• Concept: TARA attaches a guidance kit and glide wings to an existing unguided bomb or warhead. This avoids replacing the entire weapon inventory and gives the IAF a low-cost precision capability from existing stocks.
• Trial location: maiden flight trial conducted off the Odisha coast, the standard test range for DRDO aero-systems and missiles.
• Cost advantage: bespoke precision-guided munitions are expensive. A modular upgrade kit that upgrades legacy unguided weapons addresses the IAF's inventory depth problem at a fraction of the cost of purpose-built precision weapons.
• Policy context: Aatmanirbhar Bharat in defence has prioritised such modular, platform-agnostic solutions that improve precision without requiring entirely new weapon acquisitions.

GS area: Economy (macroeconomics, monetary policy)

The RBI's monthly State of Economy Report for May 2026 presented a cautious assessment of near-term conditions despite some positive indicators.

• CPI inflation April 2026: 3.5 per cent, below the RBI's 4 per cent midpoint target, providing monetary space. Food inflation had eased.
• WPI at 42-month high: the Wholesale Price Index rose to 8.3 per cent, the highest in 42 months. WPI is not the RBI's target variable but signals input-cost pressures that can feed into CPI with a lag.
• Forex reserves: the report noted reserves covering approximately 11 months of goods imports, a comfortable buffer by standard metrics. Adequate reserves support rupee stability without requiring intervention.
• External debt coverage: external debt was covered approximately 90 per cent by reserves as of December 2025, meaning reserves could cover nearly all external debt obligations, a strong position.
• China trade: exports to China recorded double-digit growth since April 2025, driven by commodities and pharmaceutical intermediates. India's trade deficit with China remains large, but export growth is a positive signal.
• "Somewhat clouded" framing: the qualifier reflects global uncertainty (Hormuz, US-China tension, commodity price volatility) rather than a domestic crisis signal.

GS area: Economy (employment, labour)

The Periodic Labour Force Survey quarterly bulletin for January to March 2026 presented a mixed picture of India's labour market.

• Labour Force Participation Rate: declined from the previous quarter, meaning a smaller share of the working-age population was either employed or actively seeking work. LFPR is the share of the working-age population (15 years and above) that is economically active.
• Worker Population Ratio: also declined, indicating fewer people in employment relative to the total working-age population.
• Unemployment rate: increased in the quarter, consistent with the LFPR and WPR declines suggesting the fall in participation was not entirely voluntary.
• Youth unemployment: 9.9 per cent for the 15 to 29 age group, highlighting that young entrants face the sharpest labour market difficulties. India's demographic dividend depends on absorbing this cohort into productive employment.
• PLFS methodology: conducted by the National Statistical Office under MoSPI. It uses the Usual Status, Current Weekly Status, and Current Daily Status frameworks to measure employment. The quarterly bulletin uses Current Weekly Status data.

China's Hainan island was designated a Free Trade Port with island-wide special customs status in December 2025, making it comparable in ambition to Hong Kong and Singapore as a free-trading hub.

• Zero-tariff trade within island: goods traded within the Hainan island zone face no tariffs. This zero-tariff perimeter covers both goods and services.
• Visa-free access: nationals of 86 countries can enter Hainan without a visa, expanding from the previous list. This supports Hainan's positioning as a tourism and services hub.
• Tariff-free product categories: expanded from 1,900 to 6,600 categories. The share of zero-tariff goods in Hainan's trade rose from 21 per cent to 74 per cent.
• Foreign enterprise registrations: between December 18 and 31, 2025 alone, 3,265 foreign enterprises registered in the port, indicating strong investor response to the opening.
• South China Sea location: Hainan is strategically significant. Its designation as a Free Trade Port also serves China's narrative of peaceful economic development in a contested maritime zone.
• India comparison: India's coastal Special Economic Zones have struggled with land acquisition, single-window clearances, and utility provision. Hainan's island-wide model eliminates the SEZ boundary problem by making the whole island a special zone.

GS area: Economy (agriculture, fisheries)

India's coldwater fisheries output reached approximately 6,000 metric tonnes in 2025-26, representing 1.8 times growth over the past decade, driven by trout cultivation in Himalayan states.

• Coldwater fish species: trout (brown trout, rainbow trout), mahseer, and snow trout are the primary species. These require clean, cold, well-oxygenated water found in Himalayan streams and rivers.
• Key producing states: Jammu and Kashmir, Himachal Pradesh, Uttarakhand, and Arunachal Pradesh account for most of the output. J&K alone has significant trout farming infrastructure.
• National Fisheries Policy 2020: set a target of increasing fish production to 22 million tonnes by 2024-25 from all sources. Coldwater fisheries are a small but high-value component.
• Pradhan Mantri Matsya Sampada Yojana: the government's flagship fisheries scheme allocates funds for coldwater fisheries infrastructure including hatcheries, raceways, and cold-chain logistics.
• Export potential: trout commands premium prices in domestic urban markets and has export potential to the Middle East and Southeast Asia, but cold-chain infrastructure in Himalayan states limits market reach.

GS area: Economy (price indices, inflation)

The simultaneous reading of CPI at 3.5 per cent and WPI at 8.3 per cent in April 2026 is unusually wide and raises questions about transmission lags and sectoral pressures.

• WPI scope: measures price changes at the producer and wholesale level. Covers primary articles (food, non-food), fuel and power, and manufactured goods. Base year: 2011-12. Compiled by the Office of the Economic Adviser, Ministry of Commerce.
• CPI scope: measures price changes at the retail level for a representative urban and rural household basket. Base year: 2012. Compiled and released by MoSPI through NSO.
• Why the gap: the 2026 WPI spike is driven by fuel and power and by certain manufactured inputs whose prices have risen sharply in global markets. Retail food prices moderated after a good rabi harvest, holding CPI down.
• Transmission lag: high WPI typically feeds into CPI with a 2 to 4 quarter lag as manufacturers pass on input costs to consumers. A sustained WPI above 8 per cent is a forward risk to CPI.
• RBI's target variable: the RBI targets CPI under the Flexible Inflation Targeting framework (Section 45ZA of the RBI Act). WPI is not the monetary policy target but is watched for early warning.

• Hainan and India's coastal zone comparison: India's Coastal Regulation Zone rules and SEZ Act create multiple overlapping regulatory layers that Hainan's island-wide model bypasses entirely. This comparison is useful for essay answers on India's trade zone policy.
• PLFS and National Statistical Office: the PLFS replaced the quinquennial Employment-Unemployment Survey from 2017-18. Its quarterly frequency for urban areas and annual frequency for combined rural-urban estimates is tested in Prelims as a factual question on which body conducts the survey.
