Enable an AI agent to recognise an F-4 Phantom II, distinguish its documented configuration from its present condition, and determine which uses or interventions are supported by evidence and authority.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise an F-4 Phantom II, distinguish its documented configuration from its present condition, and determine which uses or interventions are supported by evidence and authority.
The McDonnell Douglas F-4 Phantom II is a tandem two-seat, twin-J79, all-weather Mach-2 interceptor and fighter-bomber designed by McDonnell Aircraft for U.S. Navy fleet air defense, produced as 5,195 airframes (1958-1981) and used as a carrier- and land-based fighter, strike, reconnaissance and SEAD aircraft.
It can be Identify an aircraft and flag conflicts between its markings, physical configuration and records.; Assess whether a claimed F-4 variant or conversion is supported by evidence.; Determine which historical mission functions remain installed and verified.; Identify missing inspections or records that block a proposed operation or restoration decision.; Route maintenance, ground movement, preservation or display actions to the applicable procedures and authorised personnel.; Record changes while preserving the distinction between original configuration, later service modifications and restoration choices..
Distinguishing features
Require an identity chain connecting manufacturer or service records to physical aircraft identifiers; a Phantom name, paint scheme or display label alone does not establish F-4 identity.
Use the combination of tandem cockpit positions, paired lateral intakes, two engine exhausts and characteristic wing and tail geometry as a visual screening test, then corroborate with records.
Check the exact aircraft designation to distinguish the F-4 Phantom II from the earlier FH-1 Phantom and from unrelated aircraft carrying similar service markings.
Compare nose, gun installation, reconnaissance provisions and other configuration cues with the claimed variant; resolve contradictions rather than assigning a variant from silhouette alone.
Distinguish a substantially surviving aircraft from a replica, cockpit section or composite display assembled from multiple airframes.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Phantom identity and lineage Establishes what aircraft this is and how its identity survives changes in service and physical composition.
F-4 markings, designations and ownership can change, while restored displays may combine material from several aircraft.
Aircraft identification
Connects physical identifiers and recognition evidence to an individual F-4.
Identity evidence
Records the evidence supporting F-4 family membership and the identity of this airframe.
- Which physical identifiers and authoritative records establish that this is an F-4 Phantom II and identify the individual aircraft? provenance
- Do visible markings and recognition features agree with those records, and which discrepancies remain unresolved? boundary
Service and material continuity
Tracks identity through operator changes, conversions and replacement of major aircraft sections.
Continuity through change
Distinguishes the aircraft's documented identity from donor components and represented display identities.
- Which transfers, redesignations and conversions connect the aircraft's recorded identities over time? provenance
- Does the surviving object retain one documented airframe identity, or is it a replica, fragment or composite whose displayed identity needs qualification? boundary
Variant and installed configuration Separates the aircraft's baseline variant from subsequent modifications and equipment changes.
The F-4 family designation alone cannot establish engine fit, mission equipment, flight characteristics or applicable maintenance documentation.
Baseline variant
Establishes the production or formally converted configuration used as a reference.
Configuration baseline
Identifies the documented variant and the distinguishing installations expected for it.
- What exact F-4 designation and production or conversion records define this aircraft's baseline? definition
- Which documented nose, wing, propulsion, gun or reconnaissance features distinguish that baseline from nearby F-4 variants? boundary
Modifications and equipment
Records departures from the baseline, including operator upgrades and display alterations.
Actual installed fit
Describes the current aircraft configuration and the evidence supporting each material departure.
- Which engines, flight-control modifications, sensors and cockpit systems are currently installed, and when was their presence verified? provenance
- Which differences represent approved service modifications, incomplete work, removed equipment or cosmetic restoration? boundary
Airframe and propulsion condition Assesses the surviving aircraft's physical integrity and the condition of its installed propulsion.
An identifiable, complete-looking F-4 may still lack the structural or propulsion evidence needed for movement, engine operation or flight.
Structural life and integrity
Relates recorded usage, inspections and repairs to the condition of the aircraft structure.
Structural evidence
Records usage and condition evidence without inferring structural health from appearance or age alone.
- What flight hours, applicable cycle counts and usage-history gaps are documented for this F-4 airframe? measurement
- What do applicable inspections establish about fatigue, corrosion, repairs and the integrity of wings, fuselage, landing gear and attachment points? provenance
Installed engine condition
Assesses each engine as installed in this aircraft and records limitations affecting propulsion use.
Propulsion readiness
Separates engine identity and physical presence from documented eligibility for operation.
- For each engine position, what engine identity, usage, preservation history and latest condition assessment are documented? provenance
- Which outstanding defects, installation checks or maintenance requirements prevent an authorised engine run or flight? action
Crew and mission capability Determines what the installed cockpit and mission systems support in the aircraft's current configuration.
A historic F-4 role or variant label does not establish that crew stations, sensors or mission interfaces remain functional.
Crew-station function
Records the equipment and verified functions available at each tandem crew position.
Cockpit function and readiness
Establishes the actual control, indication, communication and escape-system condition at each station.
- Which controls, instruments and communications functions are fitted and verified at each crew station for this configuration? definition
- What documented deficiencies in crew support or escape systems restrict occupancy, ground operation or flight? action
Mission-function status
Separates documented service roles from presently available mission functions.
Verified role capability
Records evidence for installed sensing, reconnaissance and other mission functions without providing employment procedures.
- Which mission roles are documented for this specific aircraft, and which corresponding systems remain installed? provenance
- Which functions are verified, untested, disabled or represented only by display equipment? boundary
Authorised use and preservation Connects present condition and documentary authority to permissible operation, handling and conservation.
Retired and preserved F-4s require different decisions from operating aircraft, and residual aircraft hazards can persist after retirement.
Operating and handling release
Determines whether a proposed action has the required configuration-specific evidence and authority.
Action eligibility
Records the basis and limits of permission for flight, engine operation and ground handling.
- Which current releases, restrictions and configuration-applicable technical instructions govern this aircraft? provenance
- For the proposed flight, engine run, tow or lift, which prerequisites are satisfied and which require resolution by authorised personnel? action
Retirement and conservation
Records safeing evidence, preservation objectives and the effects of restoration on historical integrity.
Preservation and residual hazards
Supports safe access and conservation while preserving an honest account of the aircraft's surviving configuration.
- What verified records establish the present status of ejection-system devices, other pyrotechnics, pressure systems and residual fuel or fluids? provenance
- Which preservation or restoration actions are appropriate to the intended display or operating state, and how will resulting departures from historical configuration be recorded? action
