Purpose and description
Enable an AI agent to recognise the F-35 Lightning II aircraft family, distinguish its configurations, and identify the evidence required to assess an associated aircraft's condition and permitted use.
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, low-observable multirole combat aircraft developed through the Joint Strike Fighter program, with variants for conventional runways, short takeoff and vertical landing, and aircraft-carrier operations.
It can be Classify a documented aircraft against the F-35 family and its variant boundaries.; Compare variant specifications while retaining units, conditions and source dates.; Check whether a capability claim applies to an installed and approved configuration.; Identify missing maintenance, inspection or approval evidence before assessing readiness.; Match a variant to documented infrastructure and support-interface requirements.; Route unresolved configuration or permission questions to the responsible technical authority..
Distinguishing features
Require documented F-35 family and variant identification; a Lightning name, silhouette or manufacturer association alone does not establish membership.
Distinguish F-35A conventional takeoff and landing, F-35B short takeoff and vertical landing, and F-35C carrier operation. [Lockheed Martin variant overview](https://www.lockheedmartin.com/f35/news-and-features/The-ABCs-of-F-35.html)
Use the F-35B lift fan and swivelling propulsion nozzle as architectural checks, and F-35C wing folding and strengthened carrier landing arrangement as separate checks.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Family and variant identity Defines the registered family and the distinctions needed to classify its members.
The registry names one aircraft family, while many consequential characteristics depend on the variant.
Family boundary
Separates the F-35 family from related programmes, demonstrators and individual airframes.
Designation and membership
Require authoritative designation evidence before accepting an object or record as an F-35 family member.
- What designation and provenance establish membership in the production F-35 family? definition
- Does this record describe the aircraft family, a variant, an individual airframe or a developmental predecessor? boundary
Variant discrimination
Uses variant identification and corroborating architecture to select the applicable model branches.
Variant evidence
Treat A, B and C as branches within this registered thing; record national designations as mappings unless evidence requires a different boundary.
- Which A, B or C designation is documented, and which airframe features corroborate it? provenance
- Does a national designation identify a configuration of an existing variant or a separately defined aircraft type? boundary
Airframe, propulsion and envelopes Organises physical differences and their configuration-dependent limits.
F-35 variants cannot share unqualified dimensions, mass figures or propulsion-interface assumptions.
Physical configuration
Connects geometry and propulsion architecture to the identified variant.
Geometry and installed propulsion
Record dimensions, engine installation and any variant-specific lift or folding systems with their measurement state.
- What are the documented dimensions for this variant, including folded and unfolded spans where applicable? measurement
- Which engine and variant-specific lift-system configuration does the applicable technical record identify? provenance
Qualified performance
Keeps mass, fuel and performance figures attached to explicit definitions and conditions.
Limits and comparison basis
Distinguish published specifications, demonstrated performance and approved operating limits.
- Which variant, load state and test conditions qualify each mass, speed or range figure? measurement
- Is the cited figure an approved limit, a test result, a planning assumption or a manufacturer summary? provenance
Digital baselines and integration Qualifies aircraft capabilities through installed systems, software and interface approval.
The F-35 name alone is insufficient evidence for a particular sensor, communications or integration capability.
Hardware and software applicability
Separates announced upgrades from installed, tested and released configurations.
Capability baseline
Attach each capability assertion to the hardware, software and modification evidence needed to support it.
- Which installed hardware and software baseline supports the claimed capability? provenance
- Is that capability planned, demonstrated, installed or approved for this operator and configuration? boundary
External system interfaces
Records compatibility with approved communications, support and carried-system interfaces.
Integration and data dependencies
Treat physical fit, software integration, data currency and approval as separate requirements.
- Which configuration-specific evidence establishes compatibility with the named external system? provenance
- What authorised data or software update must be verified before declaring the interface available? action
Basing and operating authority Connects variant architecture to infrastructure requirements and permission evidence.
Conventional runway, vertical landing and catapult-and-arrestment operations require different applicability checks.
Infrastructure compatibility
Identifies the approved runway, landing-site, carrier and servicing interfaces relevant to each variant.
Site and support qualification
Require documented site compatibility instead of inferring suitability from the variant label.
- Which authority has qualified the proposed runway, vertical-landing site or carrier interface for this variant? provenance
- Which documented clearance, surface and ground-support requirements must be checked for the proposed activity? action
Permission and restrictions
Determines which military airworthiness and operator releases govern the requested activity.

- Which airworthiness authority and operator documents govern this aircraft configuration? provenance
- Does the current release permit the requested activity, and which restrictions or missing evidence prevent a decision? action
Sustainment and condition evidence Defines how linked maintenance records support assessments of an F-35 aircraft's condition.
Propulsion, variant-specific mechanisms, digital systems and low-observable maintenance can impose distinct restrictions.
Subsystem condition
Preserves subsystem-level evidence behind any overall serviceability assessment.
Fault and inspection applicability
Record faults and inspection outcomes against the applicable propulsion, lift, carrier, avionics or surface-maintenance configuration.
- Which applicable inspections or fault records establish the current condition of each relevant subsystem? provenance
- Which maintenance criteria support the recorded low-observable surface condition, and when was it assessed? measurement
Maintenance and return to service
Connects support dependencies and completed maintenance to authorised release evidence.
Support and release completeness
Check configuration-appropriate parts, consumables, support records and required sign-offs before changing a linked aircraft's serviceability assessment.
- Which approved parts, consumables, support equipment and maintenance instructions apply to this configuration? provenance
- What outstanding inspections, safety-system checks or authorised sign-offs must be resolved before return to service? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
