Resolve manufacturer and naval designations at their documented scope.
Designation equivalence
Record evidence for each name relationship without assuming that 1MT and every more specific designation have identical scope.
- Which contemporary record connects 1MT, 1MT1N and the Japanese naval service designation? provenance
- Does 1MT1N identify the complete registered type or a particular configuration within it? boundary
Visual attribution
Use the aircraft's configuration together with documentary provenance.
Recognition evidence
Assess the conjunction of wing arrangement, cockpit, engine installation and payload accommodation rather than trusting a caption alone.
- Which visible features and archival identifiers jointly support attribution to the 1MT? definition
- Could the image instead show a reconstruction, a modified airframe or another aircraft carrying a Type 10 label? boundary
Airframe and propulsion Describe the configuration needed to interpret 1MT dimensions and performance.
Triplane geometry
Establish dimensional and construction evidence for the three-wing arrangement.
Geometry and construction basis
Record configuration-specific dimensions, structural materials and drawing provenance; leave unsupported construction details unresolved.

- Which drawings or inspection records establish wing bracing, materials and structural differences between examples? provenance
Powerplant and controls
Connect the installed engine and pilot controls to documented operating evidence.
Installation-specific evidence
Require installation evidence for engine ratings, cooling, fuel, lubrication and controls instead of importing generic engine specifications.

Torpedo load and carrier use Separate torpedo accommodation, loaded performance and carrier suitability.
Payload compatibility
Establish what carriage evidence actually demonstrates.
Documented torpedo fit
Distinguish a photographed installation, an approved load and a tested load; keep torpedo internals in a neighbouring model.

- Does each cited record demonstrate static fit, flight carriage or formally accepted compatibility? boundary
Carrier performance evidence
Evaluate claims about operating from Hōshō under explicitly stated loading and test conditions.

Service evidence and material legacy Establish the type's historical status and the evidential value of surviving records or objects.
Development and acceptance
Separate milestones and procurement decisions from operational claims.
Service status and limitations
Record dates, quantities and reported handling problems with their source basis; identify the actual historical acceptance authority rather than assuming modern certification.
- Which dated records establish first flight, naval acceptance, production totals and withdrawal? provenance
- Which naval requirements or trial reports document handling deficiencies and their effect on acceptance or employment? provenance
Survival and authenticity
Determine whether material attributed to the 1MT is original, reconstructed or merely illustrative.
Material attribution and use
Link alleged survivors, components and replicas to the type through provenance while leaving object-specific condition and permissions to individual records.
- What chain of custody or original marking supports attribution of any surviving component or airframe to the 1MT? provenance
- What additional evidence is needed before attributed material can support reconstruction or conservation decisions? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
The Mitsubishi 1MT was a Japanese single-seat, single-engine triplane torpedo-bomber type developed for the Imperial Japanese Navy in the early 1920s.
In scope
- Designation relationships among Mitsubishi 1MT, 1MT1N and Navy Type 10 torpedo-aircraft names
- Recognition of its single-seat triplane torpedo-aircraft configuration
- Configuration-dependent dimensions, propulsion, loading and performance
- Evidence separating intended carrier employment from demonstrated capability
- Development, acceptance, withdrawal and surviving-material provenance
Out of scope
- Individual airframes' maintenance logs, ownership and current condition
- The general theory and operation of torpedo bombers
- Internal design and operation of the carried torpedo
- Hōshō's ship design and operational history
- Other Mitsubishi aircraft sharing Type 10 terminology
- Replica construction instructions and authorization to fly
Why it exists Filled
Enable an agent to identify the Mitsubishi 1MT aircraft type, assess evidence about its configurations and service limitations, and distinguish historical capability from intended use.
Distinguishing features Filled
- Test for the combined identity of Mitsubishi manufacture, three main wing planes, one pilot and a torpedo-aircraft role; matching only the manufacturer or wing count is insufficient. [Mitsubishi 1MT overview](https://en.wikipedia.org/wiki/Mitsubishi_1MT)
- Require designation evidence connecting 1MT or 1MT1N to the torpedo aircraft; a Type 10 label alone leaves the aircraft's identity unresolved. [Designation listing](https://commons.wikimedia.org/wiki/Category:Mitsubishi_1MT)
- Check that the record describes an aircraft type, rather than a photographed airframe, replica or scale model. [Type classification](https://commons.wikimedia.org/wiki/Category:Mitsubishi_1MT)
- Treat a carrier-role label as intended employment requiring separate capability evidence; the consulted overview reports restrictions when carrying a torpedo. [Service account](https://en.wikipedia.org/wiki/Mitsubishi_1MT)
What robots and AI may and may not do Filled
Must not
- Present a model, replica or a related design as an original airframe.
- Invent specifications or service history where records are missing.
- Misuse its military history to glorify war or for propaganda.
Only with a human decision
- Attributing found remains or artefacts to this type.
May
- Identify photographs, drawings or remains as this naval triplane type from documented features.
- Describe its development and short service from historical sources, noting gaps in the record.
Moral aspects Filled
- Early carrier aircraft history touches on the people who flew and built them in a militarized era.
- Fabricated details pollute the historical record others depend on.
Who is affected
- Historians and museums
- Descendants of aircrew
- Readers
Owners Filled
Steward
The museum or owner of any surviving example or remains; the state for items in public collections.
