The United States Army has moved forward in its artillery modernisation drive by selecting Hanwha Defence USA to advance in the Mobile Tactical Cannon program, Times of India reported.
The South Korean firm will deliver up to eighteen prototypes of its wheeled K9 Mobile Howitzer for testing and soldier trials over the next four years.
This limited procurement is intended to explore replacing the long‑serving M777 towed howitzers with a more mobile, longer‑range system.
The Indian Army also operates the M777 ultra‑light howitzer in limited numbers, but the American decision highlights a broader shift towards mobility and precision.
The K9 Mobile Howitzer is derived from Hanwha’s tracked K9 gun, which is already in service with South Korea, India, Poland and several other nations.
The tracked K9 has become one of South Korea’s most successful defence exports. Both the tracked and wheeled versions mount a 52‑calibre 155mm cannon, capable of ranges up to sixty kilometres, nearly double that of the M777.
Wheeled systems provide advantages in mobility and rapid deployment, though tracked designs remain superior in off‑road performance and protection. The US Army has been studying this shift since 2019, and while Hanwha’s selection is significant, it does not guarantee adoption.
India is already well underway on a similar journey under the Field Artillery Rationalisation Plan. This plan aims to replace legacy 105mm Indian Field Guns with modern 155mm systems across the gun‑based units of the Regiment of Artillery.
Indigenous projects such as the Advanced Towed Artillery Gun System, Dhanush and the Pinaka rocket launcher are central to this effort. The K‑9 Vajra‑T, a variant of Hanwha’s design, has been indigenised with substantial local content and has proven its worth in Ladakh. A mobile gun system based on ATAGS is also under development, reflecting India’s emphasis on mobility and precision.
Private industry has joined the push, with the Kalyani Group’s Bharat‑52 and MaRG 39 guns complementing Tata and Larsen & Toubro’s contributions. Together, these efforts highlight a synergy between public and private sectors in building a self‑reliant artillery ecosystem.
However, India’s current focus has leaned more towards wheeled systems, while the Americans are now evaluating tracked mobility as a replacement for the M777. This is where India must take note.
Tracked howitzers such as the K9 Vajra offer superior off‑road mobility, protection and survivability in high‑intensity combat environments. They can manoeuvre across rugged terrain, sustain operations in deserts, plains and mountains, and withstand counter‑battery fire through rapid shoot‑and‑scoot tactics.
Wheeled systems are lighter and faster on roads, but they lack the resilience and protection of tracked platforms in contested zones. For India, which faces diverse operational theatres ranging from the high Himalayas to desert expanses, tracked artillery provides a more versatile solution.
The American decision to test the K9 Mobile Howitzer should serve as a reminder that modern artillery must combine range, mobility and precision firepower to remain decisive.
India has already demonstrated the effectiveness of the tracked Vajra in Ladakh, where its deployment after the Galwan clashes proved critical in extreme cold weather conditions.
Expanding the tracked fleet would ensure that India’s artillery arm remains capable of rapid manoeuvre, sustained firepower and survivability against technologically advanced adversaries.
While wheeled systems have their place in rapid deployment and road‑based mobility, India should adopt the same policy as the Americans by prioritising tracked howitzers for its future artillery requirements.
This would provide the Indian Army with a balanced mix of systems, ensuring that its artillery remains effective across all terrains and operational scenarios. The synergy between indigenous development and proven foreign designs like the Vajra offers India a pathway to strengthen its artillery arm while maintaining self‑reliance.
