Learning from Europe’s FMLA: Can the HTT-40 Become India’s Counter-Drone Platform?

The European Commission (EC) has taken the lead in developing a manned light combat aircraft optimised for hunting drones. Called the Future Multirole Light Aircraft (FMLA), the concept aircraft is intended to be an affordable, versatile platform for a variety of missions.

The EC has reportedly allocated €15 million for the first phase of development under the European Defence Fund (EDF) programme for 2026.

Besides intercepting drones, the FMLA would be able to undertake close air support, reconnaissance, and target designation missions. In addition to combat missions, it would be capable of conducting border patrols and participating in search and rescue operations.

The FMLA is conceived as a turboprop aircraft with a maximum take-off weight of around 7.5 tonnes, capable of short take-offs and landings on shortened runways. It will feature lightweight composite materials to reduce radar signature and will be equipped with advanced radar, sensors, and other electronic equipment.

The aim is to develop a cost-effective aircraft with advanced technology and mission flexibility.

The Need for Specialised Counter-Drone Operations

Ukraine and Russia are both using light sport/trainer aircraft and combat helicopters for counter-drone operations.

Russia employs platforms such as the Mi-28N and Ka-52 attack helicopters, as well as light sport aircraft retrofitted with machine guns and man-portable air defence systems (MANPADS), to patrol low-altitude airspace around critical infrastructure.

Ukraine similarly uses Mi-24 and Mi-8 helicopters, L-39 trainer jets equipped with gun pods, and even modified agricultural aircraft for night operations.

These platforms operate at low altitudes and slow speeds along likely drone ingress routes, particularly during nighttime raids. Pilots rely on visual detection using night-vision systems and tactical intelligence to identify and engage hostile drones.

Drones Fight Back

The use of manned combat helicopters and light aircraft in counter-drone operations has inevitably led to the development of drones capable of shooting down these manned threats.

Air-Combat-Capable Drones

Russian forces have recently (in the past month) deployed an interceptor variant of the Geran drone capable of launching R-60 air-to-air missiles. The Soviet-era short-range missile is mounted on a launcher on top of the drone. After launch, the heat-seeking missile can autonomously home in on its target.

The interceptor variant of the Geran drone operates as part of a swarm that includes other Geran drones configured for electronic warfare, photo reconnaissance, ELINT, communications relay, and decoy missions.

When launched from a fast-flying fighter aircraft, the R-60 has a range of 7–10 km. When launched from a slow-flying drone, its effective range would be significantly lower.

First Manned Aircraft Shootdown by a Drone

A Russian Geran-2 drone may have scored its first air-to-air kill recently, potentially creating aviation history. The supporting evidence, however, remains largely circumstantial.

A Ukrainian Mi-24 helicopter from the 12th Separate Army Aviation Brigade was lost in combat on December 17, 2025.

The specific location or area of operation has not been publicly disclosed. However, in recent months, Ukrainian combat helicopters have not been operating near the front, making it unlikely that the loss resulted from a ground-launched missile.

In fact, Ukrainian combat helicopters have been largely repurposed for counter-drone operations, increasing the likelihood that the loss occurred during such a mission.

Official Ukrainian sources have acknowledged the downing as a combat loss. While it is possible that the helicopter was brought down by a Geran-2 drone—either by ramming or through the use of an air-to-air missile—other possibilities exist, including controlled flight into terrain (CFIT) while manoeuvring to engage a drone.

MANPADS Armed Drones

On January 4, 2026, a photograph of a Geran-2 drone armed with an Igla-S man-portable air defence system (MANPADS) appeared on social media.

Ukraine’s Unmanned Systems Forces reported that Ukrainian forces had intercepted a Geran-2 drone armed with the MANPADS.

The drone is claimed to have crashed in the Chernihiv region.

R-60 vs Igla-S

Upgraded variants of the Geran-2 drone are capable of carrying a tandem warhead weighing about 100 kg. Geran-2 interceptor variants replace the warhead with an air-to-air missile and its launch system.

The Igla-S missile weighs approximately 10.8 kg; with its launch system, the total weight is around 18 kg. In contrast, the R-60 air-to-air missile has a launch weight of 44 kg, while the pylon and ejector mechanism used to launch it likely weighs an additional 20–40 kg. As such, it is highly likely that the switch to the Igla-S missile is intended to significantly lighten the load on the Geran-2 drone, allowing it to operate at longer ranges.

The Igla-S missile is tube-launched, unlike the R-60, which is launched using a pylon-ejector combination.

Like the R-60, the Igla-S features an infrared homing seeker, but it is resistant to countermeasures such as flares. The missile has a range of up to 6 km.

Geran-2 drone variants capable of carrying air-to-air missiles and MANPADS feature two cameras: a forward-facing camera positioned ahead of the missile and a rear-facing camera mounted behind it.

Need for More Agile Drone Hunters with Better Missile Countermeasures

The current evolutionary trajectory of one-way attack drones and loitering munitions points to a rapidly emerging need for manned platforms capable of quickly locating and engaging drones, while also being able to evade attacks by missile-armed drone interceptors.

India’s Options

At this point in time, based on current threat perceptions and limited resources, it may not be feasible for India to develop a specialised counter-drone platform. However, India should explore the possibility of modifying the HTT-40 trainer variant into a credible counter-drone platform. I have discussed this subject in an earlier analysis for The Eurasian Times.

The Engine Delay Euphemism: HAL’s Go-To Explanation for Missed Deadlines

 


The HT, quoting PTI, reported on December 12, 2025, that HAL has revised the delivery schedule for the LCA Mk-1A and HTT-40. It now aims to deliver 5 LCA Mk-1A jets and 3 HTT-40 trainers by March 2026.

HAL had earlier committed to deliver 10 LCA Mk-1A fighters and 12 HTT-40 trainers by March 2026.

HAL attributes the timeline revision for the LCA Mk-1A to delays in the completion of weapons trials and the delivery of GE F404 engines, and for the HTT-40 to delays in delivery of the Honeywell TPE331-12B turboprop engine.

LCA Mk-1A Orders

A total of 180 Tejas Mk-1A fighters are on order with HAL — 83 against an initial order placed in February 2021 and 97 under a follow-up order placed in September 2025.

HAL has created three production lines for the aircraft.

GE-F404-IN20 Delivery

Based on the initial LCA Mk-1A order, HAL placed an order for 99 GE F404 engines with General Electric (GE) Aerospace on August 17, 2021.

Ironically, when HAL placed this order, GE Aerospace had already shut down the F404-IN20 production line after fulfilling prior commitments by delivering 65 engines for the Tejas LCA by 2016, with no further orders anticipated at that time.

HAL’s August 2021 order for an additional 99 engines required reactivation of the dormant line and vendor supply chain after a five-year hiatus. The reactivation faced further challenges because of the COVID-19 pandemic. As a result, there was a significant delay, and the first engine arrived only in March 2025.

Having resumed production in 2024, GE is now producing just a few F404 engines per month.

HAL likes to attribute LCA Mk-1A delivery timeline slippages entirely to “supply chain constraints” in the production of GE F404 engines. In reality, the slippages are largely attributable to delays in developing the Tejas Mk-1A, which led to the shutdown of the GE F404 production line. The truth is, HAL is still not ready to deliver LCA Mk-1A aircraft because of pending weapons trials.

Additional Order

The MoD, on September 26, 2025, signed a ₹62,370 crore contract with HAL for the procurement of 97 LCA Mk-1A aircraft for the Indian Air Force (IAF), including 68 fighters and 29 twin-seaters, along with associated equipment.

Delivery of these aircraft will commence during 2027–28 and be completed over a period of six years. The aircraft will have an indigenous content of over 64%, with 67 additional items incorporated over and above the previous LCA Mk-1A contract.

To fulfil the additional order, HAL announced on November 7, 2025, that it had signed a deal with GE Aerospace for 113 F404-IN20 engines. The deal, estimated to be worth $1 billion, includes a support package for execution of the programme.

The engine deliveries will take place between 2027 and 2032, HAL said in a statement on X.

According to the HT report, HAL is confident of making good on the timeline slippages in the years ahead.



HTT-40 Orders

During DefExpo 2022, HAL and the IAF signed an agreement for the supply of 70 HTT-40 trainers to the IAF for basic training.

The Ministry of Defence, on March 7, 2023, signed a contract with HAL for the supply of 70 HTT-40 Basic Trainer Aircraft.

Reportedly, HAL was to deliver the first trainer by September 2025 and a total of 12 trainers by March 2026. Supply of all 70 aircraft on order was to be completed over a period of six years.

TPE331-12B Engines

In July 2022, HAL signed a $100 million contract with Honeywell for 88 engines to power the HTT-40. Under the contract, Honeywell would deliver 32 engines, with the rest to be built at HAL through technology transfer.

Notably, HAL placed the order on Honeywell based on its DefExpo 2022 agreement with the IAF, without waiting for a formal contract from the MoD.

According to the HT report, the first engine is expected to arrive in January 2026, another four by March 31, and the rest at the rate of two per month.

HT also reports that two series-production HTT-40s are already flying with “Category B” (used) TPE331-12B engines, earlier fitted on prototype aircraft.
