1 · What happened

Hours before the opening of the St. Petersburg International Economic Forum (SPIEF) 2026, often called “Putin’s Davos”, Ukrainian drones struck the St. Petersburg Oil Terminal and the Kronstadt naval base on an island near the city. The strike damaged the Russian Baltic Fleet corvette Boiky (Project 20380, Steregushchiy-class) at the Veleshchynskyi dry dock.

Russia said 59 drones were shot down over Leningrad region (population over 5 million). Kronstadt sits about 1,100 km from Ukraine’s border — a distance previously thought safe. President Volodymyr Zelenskyy, speaking alongside NATO Secretary-General Mark Rutte, said such deep strikes let Kyiv negotiate “on an equal footing” with Moscow.

2 · Asymmetric Drone Warfare: the new combat geometry

Asymmetric warfare: A weaker party uses unconventional, low-cost tools to neutralise a stronger adversary’s expensive platforms. Long-range loitering drones now deliver that asymmetry — a few thousand dollars in airframe can disable a multi-million-dollar warship or refinery.

The Strategic Logic
Economic attrition + leverage
Kyiv targets Russian fossil-fuel sites to choke Moscow’s war funding and force a stronger negotiating posture. Strikes timed with SPIEF to deter foreign investors.
India’s Way Forward
Indigenous shield + iDEX
Project Kusha for long-range AD, Mission Sudarshan Chakra (2035) as a networked grid, and iDEX for startup-led counter-drone (C-UAS) and swarm capabilities.
The Cost Mechanism
Radical cost asymmetry
Firing a million-dollar SAM at a few-thousand-dollar drone is economically unviable. Defenders are pivoting to electronic warfare, GPS spoofing and Directed Energy Weapons (DEWs).
India-Specific Risk
Discount crude squeeze + escalation
Damage to Russian export terminals threatens India’s discounted-crude supply, spiking global fuel and freight prices. Escalation also blurs civilian/military distinctions under IHL.

  • “Dual-use” targets: Under International Humanitarian Law (IHL), refineries that fund and fuel a war effort are often classified as dual-use — legally contested but routinely struck. Geneva Conventions require strict separation of military from civilian objects.
  • India’s posture: Balances historic Russian defence ties with growing Western partnerships — emphasising strategic autonomy, dialogue and cessation of hostilities.
  • Energy buffer: India must accelerate Strategic Petroleum Reserves (SPR) expansion and diversify suppliers (Gulf, US, Africa) to absorb a Russian-supply shock.

UPSC Value Box
SPIEF St. Petersburg International Economic Forum — annual investment showcase chaired by the Russian President; often called “Putin’s Davos”.
Kronstadt Naval base on Kotlin Island near St. Petersburg; historic seat of Russia’s Baltic Fleet.
Asymmetric Warfare Conflict between unequal forces where the weaker side uses unconventional means (drones, EW, insurgency, cyber) to offset the stronger side’s superior firepower.
Counter-UAS (C-UAS) Counter-Unmanned Aerial Systems — tech to detect, track and neutralise hostile drones via jamming, spoofing, kinetic kills or DEWs.
iDEX Innovations for Defence Excellence — Ministry of Defence initiative (2018) operating under the Defence Innovation Organisation; funds startups, MSMEs and innovators in defence R&D.
Strategic Petroleum Reserves (SPR) Underground crude storage at Vishakhapatnam, Mangalore and Padur. Managed by Indian Strategic Petroleum Reserves Ltd (ISPRL), a CPSE under the Ministry of Petroleum & Natural Gas.
Directed Energy Weapons (DEWs) Lasers, microwaves and particle beams that disable targets at the speed of light with negligible cost per shot — emerging answer to swarm drones.
IHL & Geneva Conventions International Humanitarian Law mandates distinction (between civilians and combatants), proportionality, and military necessity; oil refineries straddle the “dual-use” grey zone.

MCQ Practice Question
Q. With reference to India’s defence and energy architecture, consider the following statements:

  1. iDEX (Innovations for Defence Excellence) is an initiative of the Ministry of Defence aimed at involving startups, MSMEs and individual innovators in defence research and development.
  2. India’s Strategic Petroleum Reserves (SPR) at Vishakhapatnam, Mangalore and Padur are managed by Indian Strategic Petroleum Reserves Limited, which functions as a subsidiary of NITI Aayog.
  3. Under International Humanitarian Law, oil refineries and energy infrastructure that directly sustain an opposing military are often categorised as “dual-use” objects, making the legality of striking them contested.

Which of the statements given above is/are correct?
(a) 1 and 2 only    (b) 2 and 3 only    (c) 1 and 3 only    (d) 1, 2 and 3

Answer: (c) 1 and 3 only

  • Statement 1 — Correct: iDEX, launched in 2018, sits within the Department of Defence Production under the Ministry of Defence, operated through the Defence Innovation Organisation. It funds startups and MSMEs for swarm drones, C-UAS and other emerging defence tech.
  • Statement 2 — Incorrect (the trap): ISPRL is a subsidiary of Engineers India Limited and works under the administrative control of the Ministry of Petroleum & Natural Gas — not NITI Aayog. NITI Aayog is a policy think-tank; it does not own or run Central Public Sector Enterprises.
  • Statement 3 — Correct: Energy infrastructure that fuels and finances a war effort sits in a legal grey zone under IHL. The Geneva Conventions require the principles of distinction, proportionality and military necessity, but “dual-use” objects routinely trigger disputed engagement decisions.
