What it is Filled
Ground Master 400 is a family of transportable, ground-based, three-dimensional air-surveillance radars developed by Thales, using an active electronically scanned array to detect and track aerial targets for air defence.
In scope
- GM400 product identity, manufacturer documentation and configuration lineage
- Three-dimensional air-surveillance function and configuration-specific performance evidence
- Radar equipment boundary, deployment configuration and supporting services
- Surveillance outputs and integration dependencies
- Readiness, maintenance evidence and operating authorisation
Out of scope
- The complete Ground Master radar portfolio
- Individual radar asset histories except as linked instance evidence
- National air-defence networks and command organisations
- Weapon engagement decisions and fire-control procedures
- Tactical deployment optimisation or countermeasure techniques
Why it exists Filled
Enable an agent to recognise the Ground Master 400 radar product, interpret configuration-specific capability and condition evidence, and determine whether inspection, maintenance or authorised surveillance use is supported.
Distinguishing features Filled
- Require manufacturer or procurement evidence explicitly identifying Ground Master 400 or GM400; a generic Ground Master designation is insufficient.
- Identify the product as a ground-based long-range three-dimensional air-surveillance radar, rather than a complete air-defence system.
- Distinguish the original GM400 configuration from GM400 Alpha: Thales describes Alpha as an evolution with upgraded processing and extended range. [Thales launch announcement](https://www.thalesgroup.com/en/print/pdf/node/10101)
- Separate product identity from serial-numbered equipment and from the wider installation supplying power, communications and operator facilities.
What robots and AI may and may not do Filled
Must not
- Help locate, jam, spoof or attack such radars or their crews.
- Disclose non-public technical, operational or deployment details.
- Help export or transfer such systems outside arms control rules.
Only with a human decision
- Any request touching on military use, procurement or transfer of the system.
May
- Describe this radar family from public, official and manufacturer-neutral sources.
- Report publicly announced deployments and capabilities without speculation.
Moral aspects Filled
- Air-surveillance radar protects airspace and is also a military target.
- Arms transfers can fuel conflict and abuse.
Who is affected
- Operating forces and crews
- Civilians in conflict areas
- Air traffic users
Owners Filled
Steward
The operating air force or defence ministry that holds each unit.
