Artillery shells produced by Indian arms manufacturers have been diverted by European buyers to Ukraine, and despite Moscow's protests, New Delhi has not intervened to halt the trade, according to Indian and European officials and a Reuters analysis of customs data.

The transfer of munitions to support Ukraine's defense against Russia has occurred for more than a year, according to the sources and customs data. Indian arms export regulations limit the use of weaponry to the declared purchaser, who risks future sales being terminated if unauthorized transfers occur.

The Kremlin has raised the issue on at least two occasions, including during a July meeting between Russian Foreign Minister Sergei Lavrov and his Indian counterpart, three Indian officials said.

Details of the ammunition transfers are reported by Reuters for the first time.

The foreign and defense ministries of Russia and India did not respond to questions. In January, Indian Foreign Ministry spokesperson Randhir Jaiswal told a news conference that India had not sent or sold artillery shells to Ukraine.

Two Indian government and two defense industry sources told Reuters that Delhi produced only a very small amount of the ammunition being used by Ukraine, with one official estimating that it was under 1% of the total arms imported by Kyiv since the war. The news agency couldn't determine if the munitions were resold or donated to Kyiv by European customers.

Among the European countries sending Indian munitions to Ukraine are Italy and the Czech Republic, which is leading an initiative to supply Kyiv with artillery shells from outside the European Union, according to a Spanish and a senior Indian official, as well as a former top executive at Yantra India, a state-owned company whose munitions are being used by Ukraine.

The Indian official said that Delhi was monitoring the situation. But, along with a defense industry executive with direct knowledge of the transfers, he said India had not taken any action to throttle the supply to Europe. Like most of the 20 people interviewed by Reuters, they spoke on condition of anonymity due to the sensitivity of the matter.

The Ukrainian, Italian, Spanish and Czech defense ministries did not respond to requests for comment.

Delhi and Washington, Ukraine's main security backer, have recently strengthened defense and diplomatic cooperation against the backdrop of a rising China, which both regard as their main rival.

India also has warm ties with Russia, its primary arms supplier for decades, and Prime Minister Narendra Modi has refused to join the Western-led sanctions regime against Moscow.

But Delhi, long the world's largest weapons importer, also sees the lengthy war in Europe as an opportunity to develop its nascent arms export sector, according to six Indian sources familiar with official thinking.

Ukraine, which is battling to contain a Russian offensive toward the eastern logistics hub of Pokrovsk, has a dire shortage of artillery ammunition.

The White House declined to comment and the U.S. State Department referred questions on Delhi's arms exports to the Indian government.

India exported just over $3 billion of arms between 2018 and 2023, according to data compiled by the Stockholm International Peace Research Institute think-tank.

Commercially available customs records show that in the two years before the February 2022 invasion, three major Indian ammunition makers – Yantra, Munitions India and Kalyani Strategic Systems – exported just $2.8 million in munitions components to Italy and the Czech Republic, as well as Spain and Slovenia, where defence contractors have invested heavily in supply chains for Ukraine.

Between February 2022 and July 2024, the figure had increased to $135.25 million, the data show, including completed munitions, which India began exporting to the four nations.

Friendly fire

Russia, which supplies more than 60% of Delhi's arms imports, is a valued partner for India. In July, Modi chose Moscow for his first bilateral international trip since being elected to a third term.

At another meeting that month in Kazakhstan between top Indian diplomat Subrahmanyam Jaishankar and Lavrov, the Russian minister pressed his counterpart about Indian munitions being used by Ukrainians and complained that some were made by state-owned Indian companies, according to an Indian official with direct knowledge of the encounter.

The official did not share Jaishankar's response.

Walter Ladwig, a South Asia security expert at King's College London, said the diversion of a relatively small amount of ammunition was geopolitically useful for Delhi. "It allows India to show partners in the West that it is not 'on Russia's side' in the Russia-Ukraine conflict," he said, adding that Moscow held little leverage over Delhi's decisions.
