What changes when it is defence & aerospace

Orqent Labs builds LLM applications for teams that have outgrown the prototype and need something their compliance function will actually sign off on.

In defence & aerospace, systems must run fully air-gapped, on open weights, with no external dependency whatsoever. That single fact reshapes how llm application development has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is document intelligence on classified material, usually integrated against simulation platforms. We start from the constraint, not the capability, what the system must never do, who signs off, and what happens when it is wrong.

Deployed across regulated and unregulated sectors, with audit trails where the regulator expects them. Six weeks to something running in production, not six quarters to a strategy document.

Questions from this sector

Can it work fully offline?

Yes, open-weight models on local infrastructure, with no external API calls at any point in the pipeline.

What about indigenous requirements?

Open-weight models deployed on Indian infrastructure with source-available components satisfy most indigenous content criteria; we structure builds accordingly.

Which model should we use?

It depends on the task, not on the leaderboard. We benchmark your actual workload across providers and usually end up routing, a strong model for reasoning, a cheaper one for classification and extraction.

How do you control the token cost?

Caching, routing, prompt compression and hard budget ceilings, with per-feature cost monitoring so a runaway loop shows up in hours rather than on the monthly invoice.

Can you work with our existing codebase?

Yes. Most of our LLM work lands inside an existing product rather than as a greenfield app, and we match the conventions already in your repository.

LLM Application Development for defence & aerospace, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
