What it is Filled
The P-15 radar is a Soviet mobile, two-dimensional air-surveillance radar designed primarily to detect low-flying aircraft and report their range and azimuth for air-defence operations.
In scope
- P-15 designation evidence and boundaries between original configurations and documented modifications
- Radar sensing principle, measured coordinates and limits of its surveillance role
- Antenna, radar electronics, carrier and power-supply configuration
- Evidence needed to assess completeness, serviceability and preservation state
- Interfaces, maintenance documentation and conditions for authorized handling
Out of scope
- P-19 and other successor radar types as independent designs
- Complete missile batteries, command networks and engagement doctrine
- Individual radar ownership, serial-number histories and location records except as assessment evidence
- Carrier vehicle design and roadworthiness beyond its relationship to the radar installation
- Tactical deployment, targeting, electronic attack and methods for defeating surveillance
Why it exists Filled
Enable an AI agent to identify the registered P-15 radar type, distinguish its configurations and assess documented condition and permissible handling of associated equipment.
Distinguishing features Filled
- Require designation evidence consistent with P-15 / Flat Face A; a generic 'Flat Face' label is insufficient because P-19 uses Flat Face B. [U.S. Army ODIN](https://odin.t2com.army.mil/WEG/Asset/db59831e51a23c79fce1e3eec3890b93)
- Check that the identified equipment is a mobile two-dimensional UHF radar, rather than a height-finding or three-dimensional radar. [U.S. Army ODIN](https://odin.t2com.army.mil/WEG/Asset/db59831e51a23c79fce1e3eec3890b93)
- Do not identify P-15 solely from paired elliptical reflectors: P-19 has a similar antenna arrangement, so documentary and equipment-level corroboration is required. [U.S. Army ODIN: P-19](https://odin.t2com.army.mil/WEG/Asset/P-19_%28Flat_Face_B%29_Russian_Mobile_2D_UHF_Radar)
- Require evidence identifying the radar assembly itself; a compatible truck, detached antenna or association with a missile system does not establish a complete P-15 set.
What robots and AI may and may not do Filled
Must not
- Help operate, repair or integrate it into an air-defence system.
- Provide guidance on evading or defeating air-defence radars.
- Transmit with it or any radar outside a licensed spectrum allocation.

Only with a human decision
- Any decision on demilitarising, exporting or displaying preserved equipment.
May
- Describe the radar's purpose, history and general capabilities from public sources.
- Support museums and historians in cataloguing preserved equipment.
Moral aspects Filled
- Air-defence systems are tied to war and civilian air safety; misuse can bring down aircraft.
Who is affected
- Civil aviation passengers and crews
- Military personnel
- Communities in conflict zones
Owners Filled
Steward
The armed forces or museum that holds a unit; national export control authorities regulate transfers.
