NATO's Defence Spending Surge: What a Future Summit Could Mean for India

The Ankara Summit Scenario: A 5% Defence Pledge

A hypothetical future NATO summit in Ankara could formalise a monumental shift in European security policy. In this scenario, the 32 allies, building on their 2023 Vilnius Summit pledge, would endorse a new “Hague defence commitment” to allocate a minimum of five per cent of their Gross Domestic Product (GDP) to defence by 2035. This represents a more than twofold increase from the 2% target that many members struggled to meet for years. Such a commitment would be coupled with an “ironclad” reaffirmation of collective defence under Article 5 and, most consequentially for the global market, a vow to build a high-capacity, pan-European Defence Industrial Base (DIB) to support this military expansion.

Why Europe is Prioritising Defence Industrialisation

The primary driver for this strategic re-evaluation is the altered security landscape in Europe following Russia's 2022 invasion of Ukraine. The conflict exposed critical vulnerabilities in European defence production, particularly in munitions. According to analysis in The Hindu, European defence firms like MBDA and Rheinmetall have publicly warned of production shortfalls in artillery shells and air defence missiles. This industrial revitalisation is also aimed at reducing the continent's dependency on the United States for its security. Data indicates that between 2022 and 2024, half of Europe’s defence spending was sourced from the U.S., a sharp rise from 28% in the 2019-2021 period. As per U.S. government data, Foreign Military Sales notifications to Congress for European customers quadrupled from 2008 levels, reaching $76 billion in 2024. Without a robust domestic DIB, a 5% spending pledge would primarily result in more purchases from the U.S., deepening this strategic dependency.

How a Revived NATO DIB Impacts the Global Arms Market

A massive, coordinated surge in European demand would fundamentally alter the international arms market. According to defence analyst Ajai Shukla, the market is already shifting from a “buyers’ market,” where major importers like India could leverage competition among suppliers, to a “sellers’ market,” where producers dictate terms and prioritise clients. In this new environment, NATO and European nations become the priority customers. The first signs of this shift are reportedly visible. The source material highlights a potential delay by U.S. firm General Electric Aerospace in supplying F-404 fighter jet engines, which are critical for the Indian Air Force’s Tejas Light Combat Aircraft (LCA) programme. The strain on production capacity is a global phenomenon, illustrated by the high expenditure rates of munitions in modern conflicts. For example, a hypothetical U.S. campaign expending over 850 Tomahawk cruise missiles would take a decade to replenish at the current U.S. production rate of just 85 missiles per year, demonstrating how quickly inventories can be exhausted.
