India and the United Kingdom are reportedly close to finalizing an expanded procurement agreement for the Lightweight Multirole Missile (LMM), commonly known as the Martlet, manufactured by Thales Air Defence in Belfast.
According to British officials who spoke to the Indian media, the updated contract is anticipated shortly.
Once signed, this acquisition will position India as the second-biggest operator of the Martlet worldwide, trailing only Ukraine, which has received thousands of these missiles to counter ongoing threats.
This impending international purchase naturally sparks a crucial question: Why is the Indian Army opting to import the Martlet from Britain when the Defence Research and Development Organisation (DRDO) has already successfully created the indigenous Very Short Range Air Defence System (VSHORADS) for its forward-deployed forces?
The primary reason is that while both munitions target low-flying aerial dangers, they rely on distinctly different technologies and deliver varying battlefield advantages.
DRDO's VSHORADS was purposefully built as a dedicated close-quarter air-defence shield for active combat formations.
It features an imaging infrared seeker and is powered by a dual-thrust solid-propellant rocket motor, delivering a highly portable defence mechanism against close-range aircraft, helicopters, and unmanned aerial vehicles.
Conversely, the Martlet operates on an entirely different design philosophy.
Weighing just 13 kilograms and capable of reaching speeds of Mach 1.5 with a range exceeding six kilometres, it is a versatile weapon built to strike both airborne and specific ground or maritime targets.
A major technological distinction lies in its guidance system, which relies on laser beam-riding rather than infrared homing.
This contrast in targeting methods is becoming increasingly vital in modern warfare, where swarms of cheap drones and advanced electronic warfare tactics are fundamentally changing the battlefield landscape.
Utilizing lower-cost weapons like the Martlet—estimated at around £50,000 per unit—prevents militaries from wasting million-dollar interceptors on inexpensive loitering munitions.
An infrared-guided weapon like the VSHORADS tracks the heat signature emitted by a target to steer itself to the point of impact. Once fired, the operator does not need to continuously paint the target, granting significant tactical flexibility.
This "fire-and-forget" capability is extremely beneficial for infantry soldiers stationed in vulnerable, forward-facing posts, allowing them to take cover immediately after launch.
The Martlet's laser-beam-riding technology requires a different execution. The firing unit or operator must maintain a laser beam directly on the target throughout the flight, and the missile simply rides this beam to its destination.
This provides the military with a robust alternative guidance architecture, which is highly effective against modern aircraft or drones that deploy thermal flares or other countermeasures to confuse conventional infrared-guided missiles.
Consequently, rather than competing for the same role, the two missile systems are perfectly suited to complement one another on the battlefield.
When deployed in flat terrain, the indigenous VSHORADS can establish a protective air-defence canopy over advancing army units, artillery stations, command centres, and vital logistical supply chains.
The British-made Martlet can then augment this network, contributing an extra layer of firepower with a completely different targeting mechanism to ensure no single countermeasure can defeat the entire defence grid.
This dual-layered strategy becomes even more compelling when applied to high-altitude border regions.
Operating in mountainous environments introduces severe challenges for military hardware, including thin air density, freezing temperatures, harsh landscapes, and difficult supply routes, all of which can degrade battery life, sensor accuracy, and propulsion.
Fortunately, DRDO engineers specifically tailored the VSHORADS to function reliably at extreme elevations, making it an ideal asset for securing India’s challenging northern borders.
The Martlet could introduce an additional tactical layer for troops navigating these steep terrains, as its exceptionally light weight and versatile launch platforms offer tremendous mobility.
However, its true combat effectiveness in extreme Himalayan conditions will ultimately rely on rigorous environmental testing, operational trials, and the specific deployment configurations chosen by military planners.
Beyond environmental adaptability, the decision to import the Martlet alongside an existing domestic system is driven by two core principles of modern military strategy: securing adequate stockpile numbers and ensuring technological diversification.
Contemporary air defence networks can no longer rely on a single type of interceptor.
As armed forces face a growing array of low-altitude threats like loitering munitions, quadcopters, and attack helicopters, commanders heavily benefit from possessing an arsenal equipped with varied engagement profiles and distinct tracking technologies.
By fielding both weapons, the Indian Army secures a reliable, home-grown, heat-seeking shield through the VSHORADS, while the Martlet contributes a highly adaptable, laser-guided countermeasure.
This dual approach ensures that the military's short-range defence grid is not vulnerable to a single point of technological failure or a specific type of enemy jamming.
Therefore, the anticipated procurement of the British missile should not be misinterpreted as a lack of confidence in DRDO's VSHORADS project.
Rather, the acquisition highlights the Army's strategic foresight in building a comprehensive, multi-layered, and highly diversified short-range air-defence architecture capable of adapting to modern aerial warfare.
