Purpose and description
Enable an AI agent to recognise the Northrop B-2 Spirit aircraft type, interpret evidence about individual aircraft states, and identify appropriate records, constraints and authorised next actions.
The Northrop B-2 Spirit is a United States long-range, subsonic, low-observable strategic bomber aircraft type with a flying-wing configuration, four turbofan engines and a two-person crew, designed to deliver conventional and nuclear weapons.
It can be Resolve B-2 names, images and aircraft identifiers against authoritative type and instance records.; Compare a recorded configuration with the baseline supported by a technical or historical source.; Flag missing, stale or conflicting evidence for airworthiness and maintenance review.; Check published dimensions and support requirements against a proposed facility record.; Separate documented role compatibility from current readiness and operational authorisation.; Route condition and configuration questions to the responsible maintenance, engineering or operating authority..
Distinguishing features
Require an authoritative designation linking the candidate to B-2 Spirit; a flying-wing silhouette alone does not establish identity.
Check for the characteristic tailless flying-wing airframe and absence of a conventional vertical tail, using these as supporting recognition evidence.
Distinguish the B-2 type from B-21 Raider and other flying-wing aircraft through documented designation and configuration evidence.
Separate the aircraft type from a named or numbered airframe: a tail identifier identifies an instance, not a new aircraft type.
Distinguish an operational aircraft from a mock-up, scale model or simulation even when its external appearance reproduces the B-2.
Scope
+ B-2 aircraft-type identity, naming, configuration boundaries and distinguishing airframe features
+ Relationships between the aircraft type, individual airframes and documented modification baselines
+ Publicly documented propulsion, flight-control, crew and support requirements
+ Evidence needed to assess airworthiness, maintenance condition and low-observable configuration
+ High-level mission-role compatibility and restrictions on aircraft use
- Individual airframes as independent registry concepts, including their complete event histories
- Generic aerodynamics, turbine engines and military-aircraft principles owned by broader models
- Detailed weapon design, arming procedures, targeting and strike planning
- Methods for defeating detection systems or exploiting aircraft vulnerabilities
- The manufacturer, operating organisations, air bases and acquisition programme as separate things
Characteristics
- Designation and identity evidence
- Canonical designation, aliases, issuing authority and source date Prevents visual resemblance, naming variation or historical attribution from creating duplicate concepts.
- Airframe-to-type relationship
- Individual aircraft identifier → vr.tr.northrop-b-2-spirit Keeps type-wide knowledge separate from the condition and history of a particular aircraft.
- Configuration baseline
- Documented modification or equipment baseline; unknown when unsupported Capabilities and support requirements must be tied to the configuration to which they apply.
- Airframe dimensions
- Wingspan, length and height in m, with source and configuration applicability Supports recognition and assessment of facility and handling compatibility.
- Mass and loading limits
- kg, with explicit distinction between empty mass, operating mass and published limits Prevents values defined under different loading assumptions from being treated as interchangeable.
- Published range and endurance basis
- km and h, qualified by loading assumptions and refuelling basis Keeps public performance figures attached to their stated conditions.
- Propulsion configuration
- Aircraft baseline → documented engine type and installation count Links performance and maintenance evidence to the applicable propulsion installation.
- Flight-control release status
- Released, restricted, withheld or unknown, with authority and timestamp Physical appearance does not establish that the aircraft's control systems are fit for flight.
- Low-observable condition evidence
- Documented assessment, restrictions, evidence date and access classification Separates the type's design intent from evidence about an individual aircraft's maintained condition.
- Airworthiness and maintenance disposition
- Released, restricted, under maintenance, withdrawn or unknown Determines whether an agent may recommend administrative progression or must defer to authorised review.
- Mission-role approval
- Configuration → documented role approval and approving authority Prevents a type-level mission description from being mistaken for an individual aircraft's current authorisation.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
B-2 identity and boundary Establishes what counts as the registered aircraft type and how related records attach to it.
The B-2 name can refer to a type, a particular aircraft or a representation; these require different evidence and ownership.
Designation and recognition
Combines documented identity with supporting recognition features.
Authoritative B-2 identification
Record designation evidence before using silhouette or descriptive labels to establish type membership.
- Which authoritative record identifies this subject as B-2 Spirit? provenance
- What evidence distinguishes it from B-21, another flying-wing aircraft or a B-2 representation? boundary
Type, instance and baseline
Separates the registered type from aircraft identities and changes within the type.
Airframe and modification membership
Attach individual airframes and documented configuration baselines without creating duplicate type concepts.
- Does the record describe the B-2 type, an individual airframe or a modification baseline? boundary
- Which dated record establishes the airframe's applicable configuration? provenance
Flying-wing flight system Captures the B-2's airframe, propulsion and control-system assessment requirements.
Its flying-wing form makes geometry, installed systems and flight-control evidence central to recognition and condition assessment.
Geometry and propulsion
Records configuration-qualified physical and propulsion characteristics.
Installed airframe envelope
Use documented B-2 dimensions, mass definitions and engine installation records with explicit applicability.
- What dimensions and mass limits are published, and which definitions and configuration do they use? measurement
- Which source establishes the engine type and installation count for this baseline? provenance
Control and flight release
Relates flight-control configuration to authorised assessment of flight condition.
Control-system status evidence
Represent control-system readiness through approved records rather than inference from power-on state or exterior condition.
- Which approved record establishes the applicable flight-control configuration and outstanding restrictions? provenance
- What authorised review is required when control-system release evidence is missing or inconsistent? action
Low-observable integrity Separates low-observable design identity from maintained condition and evidence limitations.
A B-2 remains the same aircraft type even when its surface condition or maintenance disposition changes; identity does not prove signature performance.
Design and evidence limits
Defines how public low-observable descriptions may be interpreted.
Qualified signature claims
Keep qualitative design descriptions separate from measured performance and unsupported numerical claims.
- What does the cited source mean by low observable in its description of the B-2? definition
- Does the source establish design intent, a measured result or only an unverified performance claim? provenance
Surface condition and restoration
Records authorised condition assessments following inspection or maintenance.
Maintained low-observable condition
Track assessment status and unresolved restrictions without encoding sensitive signature details or repair procedures.
- Which current authorised assessment establishes the aircraft's low-observable maintenance disposition? provenance
- Who must review the aircraft after a recorded surface repair or configuration change before the relevant restriction can be cleared? action
Mission role and operating envelope Organises public role descriptions, conditional performance figures and approval boundaries.
B-2 mission capability, aircraft readiness and permission to conduct an operation are separate determinations.
Role and configuration approval
Links high-level mission roles to documented configuration applicability.
Role compatibility boundary
Record public conventional and nuclear role descriptions only at the level supported by authoritative sources.
- Which source establishes each stated B-2 role and its configuration applicability? provenance
- What additional authority determines whether a particular aircraft is currently approved for that role? boundary
Conditional performance
Keeps published performance values attached to their assumptions.
Range, loading and refuelling basis
Treat range, endurance and loading figures as qualified reference values rather than universal operating guarantees.
- What loading and refuelling assumptions accompany each published range or endurance figure? measurement
- Which values are descriptive public specifications, and which are limits established by an applicable approved document? boundary
Sustainment and authorised use Connects B-2 support dependencies, maintenance evidence and release authority.
Aircraft availability depends on suitable facilities, qualified support and documented release, including requirements particular to its configuration.
Facilities and support dependencies
Identifies documented requirements for housing, handling and maintaining the aircraft.
B-2 support compatibility
Assess facility and support suitability using published requirements and authorised engineering records.
- Which documented B-2 requirements govern facility clearance, environmental conditions and ground-support compatibility? provenance
- What review is required before accepting a facility or support-equipment record as compatible? action
Maintenance and release authority
Distinguishes recorded technical condition from permission to operate.
Traceable disposition and release
Require dated maintenance disposition, applicable restrictions and responsible authority for any readiness conclusion.
- Which B-2 maintenance and military airworthiness documents govern this aircraft, and who issues them? provenance
- What may an agent record or refer for review when release evidence is expired, absent or contradicted by an unresolved defect? action
