Brahmastra Corps Chinook training under Eastern Command has demonstrated the rapid air mobility of an Ultra Light Howitzer Regiment, with the artillery unit's guns lifted underslung beneath Indian Air Force Chinook heavy lift helicopters. Eastern Command said the drill showed the corps could move potent artillery firepower into operational areas at short notice, pairing air mobility with the reach and punch of towed guns.

What the Brahmastra Corps Chinook training involved

The exercise centred on underslung loading, in which a howitzer is hooked beneath a helicopter's fuselage and flown to a landing zone rather than moved by road or rail. Eastern Command described the outcome as swift induction of combat power into operational areas, with gains in reach, agility and preparedness in terrain it called demanding and challenging.

Photographs released with the announcement show a twin rotor Chinook carrying a towed gun on twin slings, the barrel and split trail visible beneath the airframe as the aircraft climbs away from a grass strip. A second image shows ground crew steadying the same gun during hook up, moments before lift off, wheels still touching the grass as the rotor wash flattens the field around them.

The Ultra Light Howitzer's terrain problem

The Ultra Light Howitzer designation refers to the M777, the towed 155mm gun India ordered from the United States specifically because it can be broken down and moved by helicopter into terrain that rules out road-mobile artillery. The Indian Army has fielded the type along the northern and eastern borders since deliveries began in 2018, prizing its light weight over the heavier towed guns such as the indigenous Advanced Towed Artillery Gun System that now equip units built for the plains and moderate terrain rather than airlift.

A gun that can only reach a position by road loses its value the moment the road runs out. Underslung lift by Chinook removes that constraint, letting a battery leapfrog into high altitude or forested ground that has no route fit for a gun tractor.

Why the Chinook carries the load

The IAF's CH-47F Chinooks, inducted from 2019, are the only helicopters in Indian service with the underslung capacity for a 155mm howitzer and its associated load, a capacity margin the older Mi-17 fleet was never built to carry. That makes the Chinook fleet the practical bottleneck and the enabler at once for any artillery formation that wants this option in its playbook, since training slots and airframe availability now gate how many regiments can rehearse the drill in a given season.

Brahmastra Corps and its mountain strike role

Brahmastra Corps is the Indian Army's XVII Corps, raised in 2013 as the country's first dedicated Mountain Strike Corps and headquartered at Panagarh in West Bengal under Eastern Command. Its charter combines infantry, artillery, armour and an aviation wing built for rapid offensive and counter offensive action along contested high altitude terrain, part of the wider modernisation the Ministry of Defence has pushed across mountain formations.

Training an organic Ultra Light Howitzer Regiment to work with Chinooks fits that charter directly.

A joint Army-Air Force training package

Eastern Command framed the exercise as a joint effort, crediting the integration of aerial capability with artillery firepower rather than either service acting alone. The formation's own summary line for the drill, issued in both English and Hindi across its official social media channels, was blunt: rapid, agile, decisive.

No fresh deployment or tasking was announced alongside it.
