Indian Armed Forces Likely to Exclude TAPAS-BH-201 from 97 MALE Drone Order Amid Failed Altitude and Endurance Benchmarks

The Indian Armed Forces are reportedly moving toward excluding the indigenous TAPAS-BH-201 from a major procurement plan for 97 Medium Altitude Long Endurance (MALE) unmanned aerial vehicles (UAVs).

Despite years of development by the Defence Research and Development Organisation (DRDO), the platform has struggled to meet the stringent operational requirements set by the military, signaling a shift in focus toward more advanced domestic and international alternatives.

Performance Gaps and Operational Realities​

The TAPAS-BH-201, developed by the Aeronautical Development Establishment (ADE), was designed to provide India with a home-grown solution for long-range surveillance.

However, flight testing revealed that the platform could not consistently hit its target benchmarks.

While the armed forces required a service ceiling of 30,000 feet and an endurance of 24 hours, the TAPAS prototype reportedly reached only 28,000 feet with an airborne limit of approximately 18 hours.

Because of these shortfalls, military leadership now views TAPAS primarily as a "technology demonstrator"—a stepping stone for research—rather than a combat-ready system fit for active deployment.

Transition to Archer-NG​

The technical expertise gained from the TAPAS project is not being abandoned. Instead, the core technologies—including autonomous flight software, ground control stations, and sensor suites—are being integrated into the next-generation Archer-NG (Next Generation) program.

The Archer-NG features a Single Engine Twin Boom (SETB) configuration. This specific design is preferred for modern UAVs because it provides:

• Structural Efficiency: A lighter, stronger frame for long-distance flight.
• Stability: Improved flight characteristics during sensitive reconnaissance missions.
• Payload Integration: Better placement for high-resolution cameras and electronic warfare equipment.

Competitive Landscape for the 97-Drone Tender​

India’s plan to acquire 97 MALE-class drones represents one of the world's largest unmanned aviation contracts.

Approximately 24 companies, both domestic and international, have expressed interest. This massive procurement aims to bolster the surveillance capabilities of the Army, Navy, and Air Force simultaneously.

While there was initial hope that the Indian Navy might adopt TAPAS for maritime patrol due to its ability to use shorter runways in island territories, the Navy has reportedly declined.

Current naval interests have shifted toward the Hermes 900, a proven platform being manufactured in India through a partnership with Adani Defence & Aerospace.

Technological Legacy and Indigenous Powerplants​

Despite the TAPAS-BH-201's likely exclusion from the frontline, the program has successfully catalysed the domestic defence ecosystem.

A significant spin-off includes the development of a home-grown 2.2-litre turbocharged engine intended to replace foreign powerplants.

This engine is a collaborative effort between the Vehicles Research and Development Establishment (VRDE) and Jayem Automotives.

Open-source data suggests that India is also fast-tracking the acquisition of MQ-9B SkyGuardian/SeaGuardian drones from the United States to fill immediate high-altitude gaps, while the Archer-NG is groomed to fulfill long-term sovereign requirements.

I really don't understand. Whether the army wants only foreign products by citing certain lacunae or the indigenous idiots don't meet out the requirements

Yes , looks like it!
Probably for kickbacks as corruption seeps so deep in our country.

Whose against bringing pvt players in their sane mind .
We are just saying dont kill peacock to raise snakes.
We don't want to see a day when PSUs are no more and PVT defence giants arm twisting India Inc making policy decisions like gheu do in USA or western world.
If they want share improve capabilities and work on it and compete on merit not favours . Specially if they are so good as you imply! Don't just do assembly work and foreign copies.

PSU designed AMCA and nove HAL which made entire Airplanes for 80+ years is barred from even participation.
Meanwhile we see aseembly workers and newbies are favoured.
Reliance defence was 10 days old when it got Rafale offset with special favours, It can't even design an airframe after these years of assembly. So is the merit.

I would say, lets open the field for both PSU and prvt players...lets see who will win the battle.

The biggest gripe everyone has with PSUs is that they're extremely slow in decision making and delivery. Plus, even their workmanship is of shoddy calibre as we have seen in the crashes with Tejas, Su30MKi or our Mig21. HAL was the reason the OG MMRCA deal went through cracks as Dassault wasn't ready to take ownership of HAL made jets...

Kalyani Group is a pioneer in pvt players. PSUs are even not able to properly Forge an artillery gun "please read about sharang fiasco".

Unless PSUs are not heavily fined for their mistakes, they will never improve. This govt job syndrome has made them atleast 2 decades behind from the current modern warfare.
