KNDS-HAL sign contract for 126 THL20 Gun Turrets for LCH Prachand: Hindustan Aeronautics Limited (HAL) has signed a contract with European defence company KNDS for 126 THL20 gun turrets for India’s Light Combat Helicopter (LCH) Prachand, adding a new layer of firepower to a platform designed for some of the country’s most demanding operating environments.

The agreement was formally signed on 17 September 2026 and will provide newly manufactured THL20 turrets built around the 20M621 20mm cannon. The weapon uses NATO-standard 20×102mm ammunition and is designed to be integrated with the Prachand’s existing sighting and fire-control systems.

The deal is significant because the Prachand has been developed specifically as a combat helicopter capable of operating in high-altitude areas, where weight, stability, weapon performance and reliability are particularly important.

The addition of the THL20 is intended to give pilots another flexible weapon option for close combat and anti-armour missions, complementing the helicopter’s existing missile and rocket systems.

What is the THL20 turret?

The THL20 is a lightweight, compact gun turret designed specifically for integration with helicopters.

At its centre is the 20M621 cannon, which fires 20mm ammunition. Unlike a fixed gun mounted directly on an aircraft structure, a turret can provide greater flexibility in how the weapon is positioned and aimed.

For a combat helicopter, this can be useful during close-support missions where targets may not always be directly in front of the aircraft.

The THL20 has been designed with a low-recoil system, an important characteristic for a helicopter-mounted weapon. Recoil can affect an aircraft’s stability, particularly when firing repeated bursts. Managing that force helps maintain the platform’s handling characteristics and supports more accurate engagement.

The turret is also designed to work with the helicopter’s sighting and fire-control architecture. This means the weapon is not being treated as an isolated component but as part of the wider combat system.

Why the Prachand needs multiple weapons

The Prachand is designed to perform a range of combat missions, particularly in challenging terrain.

Its existing weapons include Dhruvastra anti-tank guided missiles, Mistral-2 air-to-air missiles, 70mm rockets and a chin-mounted cannon.

Each weapon provides a different capability.

Anti-tank guided missiles are intended for engaging armoured targets at greater distances, while air-to-air missiles provide protection and engagement capability against airborne threats. Rockets can be used against a variety of ground targets.

A gun turret adds another option, particularly for engagements where pilots require a weapon that can be fired repeatedly and precisely at relatively close range.

This combination gives the Prachand greater flexibility rather than relying on a single weapon system for different battlefield situations.

For operations in mountainous and high-altitude areas, where engagement distances and terrain can vary considerably, that flexibility can be important.

A system with an established Indian connection

KNDS is not new to India’s helicopter fleet.

The company has previously supplied 136 THL20 turrets for the Advanced Light Helicopter. That earlier programme provides an existing reference point for the integration and support of the weapon on Indian rotary-wing platforms.

The THL20 also has a wider combat aviation pedigree. Its design is derived from the THL30 turret, which is already used on Tiger attack helicopters.

For HAL, this existing experience can potentially reduce some of the uncertainties associated with introducing an entirely new weapon system.

The new contract also strengthens KNDS’s position within India’s broader defence ecosystem.

How the deal fits into Make in India

The THL20 turrets themselves are being imported, meaning the contract does not represent a fully indigenous development.

However, the relationship between KNDS and Indian industry has expanded beyond the supply of finished defence equipment.

The company has developed partnerships with Indian firms, including SMPP for ammunition production. KNDS also supplies other equipment to India, including 30mm 30M791 guns for Rafale aircraft and precision-guided munitions.

These industrial links form part of the wider effort to build domestic manufacturing capabilities while continuing to procure selected technologies from international suppliers.

For India, this represents a balance between developing indigenous systems and acquiring established technologies where they can be integrated into domestic platforms.

The trade-off: capability versus foreign dependence

The contract also highlights one of the challenges facing India’s defence modernisation programme.

While importing a proven system can provide access to mature technology, it can also leave the user dependent on an overseas supplier for some spares, maintenance support, upgrades and future modifications.

Those dependencies can have financial and logistical implications over the lifetime of a weapon system.

An indigenous turret would potentially provide India with greater control over development and sustainment, but developing such a system from scratch would require time, investment and extensive testing.

For the Prachand programme, the THL20 therefore represents a pragmatic route to adding a mature weapon capability while India’s domestic defence industry continues to expand its ability to design and manufacture complex systems.

Timing will be crucial

The integration of the turrets will also have to match HAL’s production and delivery schedule for the Prachand.

The Ministry of Defence has signed contracts covering 156 Prachand helicopters, with deliveries scheduled to begin in 2028. The contracts are reportedly worth around ₹62,700 crore.

That makes the timing of the THL20 programme important. The turrets need to be delivered, integrated, tested and supported in line with the helicopter production schedule.

Any delays in one part of the supply chain could potentially affect the broader process of delivering fully equipped helicopters to the armed forces.

What the contract means for the Prachand

The 126-turret agreement does not transform the Prachand into a new helicopter, but it strengthens one of the platform’s most important attributes: its ability to deliver accurate firepower in difficult operating conditions.

The THL20’s compact design, low-recoil characteristics and integration with the helicopter’s fire-control systems are intended to give pilots another precise and flexible weapon option.

For HAL, the contract represents another step in building the Prachand into a mature combat platform. For KNDS, it expands an established relationship with India’s military aviation sector.

More broadly, the deal illustrates the path India is taking in defence modernisation: developing major platforms domestically while selectively incorporating foreign technologies where they can provide established capabilities.

As the Prachand fleet grows, the integration of the THL20 will be closely watched not only for the additional firepower it provides, but also for how effectively India manages the balance between immediate capability, domestic industrial development and long-term control over critical defence technologies.
