What it is Filled
The Curtiss A-12 Shrike was an American two-seat, single-engine, low-wing attack monoplane with fixed landing gear, developed from the Curtiss A-8 and operated during the 1930s.
In scope
- A-12 designation, manufacturer identity and boundaries within the Curtiss Shrike lineage
- Airframe recognition, crew arrangement and configuration-dependent dimensions
- Radial-engine installation, propeller compatibility and documented performance conditions
- Historical attack equipment and its effects on aircraft configuration
- Service attribution, technical-document applicability and preservation assessment
Out of scope
- Independent models of the Curtiss A-8 and YA-10 predecessors
- Other aircraft bearing A-12 or Shrike names
- Generic piston-engine aircraft principles
- Individual airframe ownership, maintenance logs and flight authorization records
- Standalone engines, weapons and ammunition as separately registered things
- Scale models, replicas and photographs as collection objects
Why it exists Filled
Enable an agent to identify the Curtiss A-12 Shrike aircraft type, assess evidence about its configurations and condition, and determine appropriate documentation or preservation actions.
Distinguishing features Filled
- Require Curtiss manufacturer attribution and the A-12 designation together; neither A-12 nor Shrike alone establishes identity.
- Check the single radial-engine nose against the inline-engine A-8 configuration; establish engine subtype from applicable documentation rather than silhouette alone.
- Use the combined low-wing monoplane layout, fixed main landing gear and tandem crew positions as recognition evidence, not as a unique identifier.
- Distinguish production A-12 attribution from the radial-engined YA-10 predecessor through designation, serial evidence and cockpit-layout documentation.
- Separate full-size aircraft from representations: Smithsonian object A19840127000 is explicitly a 1/16-scale exhibit model. [Smithsonian collection record](https://www.si.edu/object/model-static-curtiss-12-shrike%3Anasm_A19840127000)
What robots and AI may and may not do Filled

Only with a human decision
- Restoration or loan of a surviving airframe.
May
- Identify photographs or a surviving airframe as this attack monoplane type.
