Spending a whopping $50.6 billion on defence in 2016, India has become one of the world's top-five defence spenders.

Eclipsing Saudi Arabia and Russia, India now has the world's fourth-largest defence budget, according to the 2016 Jane’s Defence Budgets Report, released by research firm IHS Markit on December 12.

Why is India the world's top arms buyer?

While the United States, China and the United Kingdom secured the top three spots respectively, the report suggested that India was likely to surpass the UK by 2018 to become the world's third-largest defence spender.

“Procurement spending has been constrained in India over the last three years as personnel costs have increased,” IHS Jane’s principal analyst Craig Caffrey said in a statement. “However, what we expect to see from 2017 onwards is a military focused on modernisation. India needs new equipment. Over the next three years, India will re-emerge as a key growth market for defence suppliers.”

While Saudi Arabia secured fifth spot, Russia slipped to sixth. This year, total global defence spending increased to $1.57 trillion.

According to the Stockholm International Peace Research Institute (SIPRI), India remained the biggest importer of major arms, spending $3.078 billion accounting for 14% of the total, as compared to Pakistan, whose arms imports in 2015 declined, accounting for 3.3% of global arms imports at $735 million.
