Flagship · Hybrid VTOL Fixed‑WingSHOURYA
MK4
Takes off like a drone. Flies like an aircraft.
Shourya Mk4 is a 3‑metre hybrid VTOL fixed‑wing UAV — designed, engineered and manufactured at Sarus Aerospace with 97% indigenous components under the Make in India / Atmanirbhar Bharat initiative.
Four vertical‑lift motors get it off the ground from any unprepared terrain; a rear pusher motor carries it on efficient fixed‑wing cruise for up to 90 minutes with a full 5 kg payload. No runway, no launcher catapult, no recovery net needed.
Built from high‑strength carbon fibre composite, Kevlar and aerospace‑grade aluminium, it packs into a single compact transport box (1420 × 430 × 470 mm) and is flight‑ready in 10 minutes by a crew of one — completely tool‑less.
Value proposition
Engineered for the field: hard to detect, hard to jam, easy to carry and quick to deploy — across civil and defence missions.
Indigenous components
Designed and built in India — Atmanirbhar Bharat platform.
Max altitude (MSL)
High‑altitude and mountainous terrain operational capability.
Max payload
EO/IR gimbals, delivery pods or mission modules.
Endurance @ 5 kg
Long loiter and wide mission radius under full load.
Wingspan
High-efficiency aerodynamic carbon composite wing.
Max speed
18–25 m/s efficient fixed-wing cruise speed.
Assembly
Set up and fly in 10 minutes, single crew member.
Compact transport
Single rugged 1420 × 430 × 470 mm transport box.
GPS jamming / spoofing
Frequency hopping and robust GPS‑denied navigation.
Radar detection
Anti‑radar coating significantly reduces radar cross-section.
Operating temperature
From high Himalayan passes to extreme desert heat.
Wind resistance
Stable in turbulent gusty, real‑world operational conditions.
Parachute recovery
Emergency recovery parachute for asset and payload protection.
Multi‑application
Surveillance, Delivery, Kamikaze, DOOAF and Training roles.
