India is taking a major step toward upgrading its artillery by planning to purchase an additional 200 K-9 Vajra tracked self-propelled howitzers.
This new order will eventually double the Indian Army's current active fleet to 400 units, establishing one of the largest K-9 forces in the world.
The first batch of 100 guns, built by Larsen & Toubro (L&T) in partnership with South Korea's Hanwha Aerospace, featured roughly 50 percent local components and was completely delivered ahead of schedule in 2021.
A second contract for another 100 units, valued at over ₹7,600 crore, was finalised in late 2024 with indigenous parts increased to 60 percent.
Government officials now indicate that this upcoming third phase will push domestic manufacturing even higher to 70 percent, highlighting India's accelerating commitment to self-reliance in the defence sector.
The K-9 Vajra is an Indian adaptation of the South Korean K9 Thunder, a formidable 155mm, 52-calibre artillery system.
While the initial batch was specifically designed for the hot, sandy deserts of Rajasthan, the 50-tonne weapon system has proven highly adaptable.
Recent versions have been heavily modified for mountain warfare in high-altitude regions like Ladakh and Sikkim.
These mountain-ready guns are fitted with special winterisation kits, which include advanced heating systems, modified lubricants that resist freezing at -20 degrees Celsius, and specialised auxiliary power units (APUs).
These critical upgrades allow the howitzer to operate smoothly in freezing conditions, transforming it from a desert-optimised weapon into an all-weather, all-terrain military asset.
The planned procurement of these 200 guns is part of broader "Phase-3" diplomatic and military discussions between New Delhi and Seoul. These advanced negotiations are focused on extensive technology transfer rather than simple direct purchases.
Future collaboration is expected to cover complex subsystems like advanced fire control mechanisms, heavy-duty electronics, and specialised armour materials.
Statements from the Ministry of External Affairs suggest that this partnership may expand beyond artillery, potentially paving the way for joint development of anti-aircraft systems and next-generation missile platforms.
By integrating Indian manufacturers deeply into the supply chain, India aims to build a robust domestic defence industry while maintaining complete control over its military operations.
The true capabilities of the K-9 Vajra were put to the test and proven during Operation Sindoor in May 2025.
During a critical 25-minute strike window on May 7, the Indian Army used the tracked K-9s alongside lightweight M777 towed howitzers to create a layered and devastating wall of artillery fire.
By firing GPS-guided M982 Excalibur shells, the K-9 was able to accurately hit targets at its maximum extended range of nearly 50 kilometres.
This long-reach firepower enabled Indian forces to safely destroy hostile launch pads and supply bases located deep inside enemy territory without exposing their own troops to frontline dangers.
The heavy artillery system proved its battlefield worth again on May 12, 2025, when Pakistan attempted retaliatory strikes against Indian logistics hubs and airbases, including Nur Khan and Rahimyar Khan.
The K-9 units successfully executed rapid counter-attacks while ensuring their own survival.
Utilizing a "shoot-and-scoot" strategy—which allows the howitzer to stop, fire, and move to a new location in under a minute—the K-9 crews easily evaded enemy precision weapons and loitering drones.
Supported by a powerful 1,000-horsepower engine, the tracked vehicle navigated the steep, rugged mountain terrain with surprising agility, proving that heavy self-propelled guns can be highly effective in mountain environments traditionally dominated by towed artillery.
Ultimately, the events of Operation Sindoor permanently shifted how the Indian military views the K-9 Vajra. Instead of seeing it just as a heavily armoured gun platform, the Army now recognizes it as a highly accurate, networked strike weapon capable of delivering fast and survivable firepower.
The military has applied lessons from this conflict to the design of the newer batches. Future units will feature highly indigenised communication suites and digital Fire Control Systems that support Multiple Rounds Simultaneous Impact (MRSI) capabilities.
These advanced electronics will allow the K-9 to connect seamlessly with India's broader military networks, ensuring instant data sharing, real-time targeting, and coordinated attacks across the battlefield.
