Vritra / Hunter-Killer UAV

Indigenous aerospace.
Engineered
in India.

Taiyo Aerospace is building a man-portable, jet-powered, AI-piloted strike platform — designed and manufactured in India to close the sensor-to-shooter gap in under sixty seconds.

Our charter

Bootstrapped
Why we exist

Modern conflict moves in minutes. India's frontline units deserve indigenous aerial combat systems — not legacy imports retrofitted for a battlespace they were never designed for.

Taiyo Aerospace was founded in 2024 to develop sovereign aerospace capabilities for India. Our first product, Vritra, is a jet-powered, AI-piloted, man-portable platform built from the ground up for tactical response and time-sensitive strike. We design our airframes, write our flight code, and intend to build our own engines.

02 / Problem

The sensor-to-shooter gap

Time-sensitive targets

Mobile threats — rocket artillery, air defence, command vehicles — shoot and scoot in minutes. Today, infantry units find them with slow drones, then call for separate strike support. The result is a 30–45 minute lag that lets high-value targets escape.

Tactical Drones
< 150 km/h

Too slow and easily detected by radar. Can observe but cannot engage — forced to wait for fire support.

Strategic UAVs
SCARCE

MALE/HALE platforms are high-value assets. Cannot be risked at low altitude and rarely available on demand.

Manned Aircraft
30–45 MIN

Too expensive for hunting small, fleeting targets. In denied airspace or remote terrain, arrival can take over thirty minutes.

VRITRA

Find. Fix. Finish.

A man-portable, jet-powered kill chain. Two ruggedized cases fit in an SUV. Ten minutes from case-open to launch. Onboard AI compresses target acquisition, decision, and engagement into a single autonomous loop — even when comms are denied.

04 / Capabilities

One airframe. Three missions.

15kg modular bay
CONFIG / A

Precision Strike

Two miniaturised loitering munitions or laser-guided rockets on internal hardpoints. Optimised for hard targets — armour, artillery, transporter-erector launchers.

CONFIG / B

COIN Support

Specialised, dampened mount for a 7.62mm gun pod. Highly cost-effective for counter-insurgency operations with multiple re-engagement passes.

CONFIG / C

ISR & Overwatch

Additional fuel bladders for extended endurance. Enhanced ELINT/SIGINT sensors for long-duration intelligence gathering and persistent overwatch.

Setup
<10 min

Case-open to ready-to-launch by a 2-person crew.

Assembly
Tool-less

Click-lock joints with screw-lock MIL connectors.

Fuel
Multi-fuel

Standard Jet-A1 or military-grade diesel.

Turnaround
<10 min

Hot-pit refuel for high-tempo surge operations.

Where we are

Ground testing
70% Scale Prototype · Validated Vritra prototype

Aerodynamics validated. Carbon-fibre monocoque in manufacturing.

We designed, built, and flew a 70% scale prototype to validate our aerodynamic design. Yaw response, climb performance, pitch authority, and surface drag all met or exceeded targets.

The full-scale carbon-fibre monocoque airframe is now in manufacturing. JetCat P-250 procurement is underway. Overmier AI integration is planned for the production airframe upon completion.

Incremental de-risking
PHASE / 01 CURRENT

Electric Ducted Fan

Prototype validation of airframe, avionics, and AI systems at reduced speed. Low-risk flight envelope exploration.

PHASE / 03 FUTURE

Indigenous Turbine

Indian-developed and manufactured engine for strategic independence, optimised thrust, and supply-chain sovereignty.

08 / Team

The founders

UIUC · Bengaluru

Engineers from the University of Illinois at Urbana-Champaign with hands-on experience building fixed-wing, quadcopter, and hybrid UAVs — from airframe design through autonomous systems and jet propulsion.

We built our initial capabilities through the SUAS Competition, delivering mission-specific drones under tight timelines. We bootstrapped both the 70% scale and full production prototypes — covering all design, fabrication, and testing costs independently.
