Uncrewed aerial system
NEMESIS
A family of uncrewed aircraft for surveillance and precision strike. Nemesis gives a small team eyes above the ground and, in its loitering munition configuration, a precise way to act on what they see, with a trained operator making every decision.
Illustrative model. Drag to rotate
One aircraft family, two jobs.
Nemesis shares one airframe, flight software and ground control across its configurations, so units train once and maintain one system.
Surveillance
Live video above patrol routes, borders and convoy routes, shared with every unit on the network. It watches, reports and returns.
Loitering munition
Holds over an area for as long as the mission needs, finds and tracks targets, and engages only when an operator confirms. Until then it keeps watching.
Performance figures are not published. Endurance, range, payload, datalink and launch details are shared only with authorised government and defence buyers, under NDA, in a briefing.
How a mission runs.
Step through a Nemesis mission. The aircraft does the flying, searching and tracking. People make the decisions.
Launch
A small team launches Nemesis from the field. It climbs and flies itself to the area of interest the operator has chosen.
Decided by: Operator
Search
It loiters over the area and streams live video to the operator. Through Sentinel OS, ground units and command see the same picture.
Done by: Aircraft, watched by the operator
Track
When the operator marks something of interest, Nemesis keeps it in view as it moves, so nothing is lost while people assess it.
Selected by: Operator
Human decision
Nothing happens until a trained operator positively identifies the target and gives an explicit command. Nemesis does not choose targets on its own.
Decided by: Operator, every time
Act or call off
The surveillance configuration keeps watching and reports. The loitering munition configuration engages only on the operator's command, and is designed so the operator can call it off and send it back to watching.
Decided by: Operator
Simplified for illustration. Real missions follow each unit's rules of engagement.
IllustrativeA person decides. Every time.
Nemesis automates the flying and the watching. The decision to act stays with a trained operator, by design.
Positive identification
Operators see live video and confirm what they are looking at before any decision is made.
Explicit command
Engagement needs a deliberate operator command. There is no automatic engagement mode.
Call it off
Designed so the operator can stop an engagement and return the aircraft to watching.
Operator roles
Separate access for commanders, operators and observers through Sentinel OS.
One shared picture
What Nemesis sees is shared with ground units and command, so everyone works from the same view.
Made in India
Airframe, electronics and flight software are developed in-house at our Kerala facility.
Eyes above, wheels below.
Nemesis runs on DRL Sentinel OS, the same operating system as STRYKER. Air and ground units share data directly and can be planned and watched from one place.
- Overwatch for ground patrols
- Nemesis flies ahead of STRYKER and spots what the rover cannot see from the ground.
- One plan, two domains
- Plan air and ground routes together and follow both on one map.
- Works without the cloud
- Units keep sharing data directly when networks are jammed or absent.
- Same software, less training
- One operating system across every drubelabs system.
Where it flies.
Nemesis is designed for small units that need to see further and act precisely without putting people in the open.
Overwatch for patrols
Surveillance configuration, live video, Sentinel OS
Flies ahead of a patrol or convoy and warns them of what is waiting before they get there.
Border and perimeter surveillance
Surveillance configuration, long loiter
Watches remote stretches of border or the perimeter of a base, day and night, from above.
Precision engagement
Loitering munition configuration, operator command
Engages confirmed military targets on an operator's command, with far less risk to people and property nearby than larger weapons.
Force protection
Both configurations, shared picture with STRYKER
Gives a forward post its own air picture, working alongside STRYKER on the ground.
Responsible by design.
Nemesis is a weapon system in its strike configuration. We build and sell it with that responsibility in mind.
Authorised buyers only
Available only to government, defence and security agencies. We do not sell to individuals or private groups.
End-use checks
Every sale follows Indian export and end-use regulations, including end-user documentation.
Human control
Built around meaningful human control over every engagement decision.
Where Nemesis is today.
Nemesis is in active development at drubelabs, Kerala Startup Mission, Kalamassery.
- DevelopmentAirframe, flight software and Sentinel OS integration.
- Flight testingControlled trials of both configurations.
- EvaluationTrials with authorised partner units.
- ProductionBuilds for approved customers.
