1. Priority Risk Register
| ID | Risk | Likelihood | Impact | Primary mitigation | Accountable lead | Decision gate |
|---|---|---|---|---|---|---|
| R-01 | Requirements expand faster than design maturity. | High | Critical | Mission-priority lock, design margins, and no capability change after production award; enhancements move to the next hull, lot, flight, or scheduled refit. | Program executive / requirements authority | Requirements baseline and each flight authorization |
| R-02 | Three new hull designs create excessive simultaneous design workload. | High | Critical | Stagger design releases, common standards, independent design reviews, land-based integration, mature design before construction. | NAVSEA design authority | Preliminary and critical design reviews |
| R-03 | New technologies drive concurrency and rework. | High | Critical | Three-new-technologies-per-flight rule, proven fallbacks, off-ship test, interface control, certification before insertion. | Chief engineer / test authority | Technology readiness and flight insertion review |
| R-04 | Weight, stability, power, cooling, or data margins erode. | High | Critical | Service-life margin policy, continuous weight report, configuration control, class-specific loading limits. | Chief naval architect | Each design review and module certification |
| R-05 | Odyssey pods do not meet shock, acoustic, efficiency, or survivability needs. | Medium | Critical | Full-scale land and water test, representative mount, damage trials, shaft/rudder fallback for early hulls. | Propulsion system program manager | Pod certification before ship insertion |
| R-06 | PRIME package cannot meet energy, safety, mass, or flight-deck constraints. | High | Critical | Define MWh duty, chemistry trade, fire testing, crash and shock analysis, smaller modular fallback. | Electrical and battery safety authority | Battery preliminary design and abuse-test review |
| R-07 | Mk 57 PVLS missile inventory and qualification do not support the desired loadout. | Medium | Critical | Missile-by-missile certification plan, canister strategy, Mk 41 VLS stopgap IWM, no automatic compatibility assumptions. | Weapons integration authority | Launcher and combat-system certification |
| R-08 | Trinion development fails cost, accuracy, barrel-life, ammunition, or schedule goals. | High | Major | Independent gun program, land firing, Mk 45 Mod 4 fallback, no ship delay tied to Trinion. | Naval guns program manager | Weapon qualification before IWM insertion |
| R-09 | Open architecture remains vendor-dependent in implementation. | High | Major | Government-owned interfaces and data, modular contracting, reference implementation, conformance test, competition rights. | Digital engineering / contracting authority | Software and interface acceptance |
| R-10 | Cyberattack or software faults propagate across common systems. | High | Critical | Segmentation, safety partitioning, zero-trust controls, local modes, red-team test, signed updates, recovery baselines. | Cyber authority | Cyber risk assessment and operational test |
| R-11 | Yard construction and environmental cleanup delay production. | High | Critical | Parallel site studies, phased work packages, lawful cleanup/construction sequencing, alternate sites, independent schedule reserve. | Industrial-base and environmental leads | Site acquisition and construction authorization |
| R-12 | Workforce growth cannot match yard and module demand. | High | Critical | Regional training pipelines, apprenticeships, housing/transport support, trainers, retention metrics, realistic ramp rates. | Workforce director | Annual capacity and build-start review |
| R-13 | Suppliers cannot meet material, propulsion, electronics, or munition demand. | High | Critical | DLA demand signal, second sources, strategic inventory, long-lead buys, qualification capacity, supplier health monitoring. | DLA / supply-chain director | Material readiness review before each start |
| R-14 | Production schedule exceeds realistic yard throughput. | High | Critical | Integrated master schedule, lane loading model, design-complete gates, risk-adjusted starts, independent schedule assessment. | Production director | Annual ship-start authorization |
| R-15 | Standard refits exceed the planned availability. | Medium | Major | Pre-staged exchange inventory, condition data, advance planning, representative pilot refit, critical-path tracking. | Lifecycle and maintenance director | First-class refit demonstration |
| R-16 | Cost and ROI assumptions do not survive independent review. | High | Critical | Independent cost estimate, base-year discipline, sensitivity cases, risk reserve, separate appropriations and lease-recovery accounting. | Cost assessment authority | Milestone and multiyear funding decision |
| R-17 | Crew size, training, or maintenance workload is understated. | Medium | Critical | Task analysis, watchbill modeling, maintainability demonstrations, training pipeline and shore-support model. | Fleet manpower authority | Human-systems integration review |
| R-18 | Threat requirements outpace the five-year upgrade path. | Medium | Major | Software releases, ISO mission changes, urgent alteration path, reserved margins, annual threat review. | Requirements and fleet modernization leads | Annual threat-to-capability review |
| R-19 | SCUTUM position density creates conflicting firing arcs, topweight, aviation restrictions, sensor interference, or excessive watchstanding demand. | Medium | Major | Reserve foundations early, validate class-specific locations, cap unused positions, automate where justified, and approve payload mixes through weapons-safety and human-systems reviews. | Weapons integration and naval-architecture authorities | Topside arrangement and representative adapter certification |
| R-20 | Legacy vendors decline rights terms or use background IP to preserve sole-source control. | High | Major | Audit existing government rights case by case; buy or license only when it is better lifecycle value than replacement; continue the legacy product while a government-controlled successor is competed, tested, accepted, supported, and stocked. | Acquisition executive / intellectual-property counsel | Legacy-system transition gate before each source or replacement decision |
| R-21 | The government lacks enough acquisition, engineering, DLA, legal, test, inspection, cyber, and configuration-control personnel to govern the expanded program. | High | Critical | Fund the government program office and DLA expansion as explicit program elements; phase workload to staffed capacity; use independent technical authorities and measurable acceptance gates. | Program executive / DLA / service acquisition executive | Staffing certification before each design, yard, campus, and production expansion wave |
| R-22 | Stakeholder-directed changes after award cause delay, rework, and cost growth. | High | Critical | Freeze the awarded configuration. Route capability improvements to the next hull, lot, flight, or 60-month refit. Current-production action is limited to verified defect, safety, cybersecurity, physical or information security, legal or regulatory compliance, or unavailable-part form-fit-function correction, and the exception cannot add capability. | Configuration-control authority | Award baseline and every proposed corrective-action decision |
| R-23 | Annual funding instability breaks economic production rates, supplier investment, cleanup, training, or yard ROI before the program can demonstrate value. | High | Critical | Maintain an independently verified minimum viable Navy request; use authorized multiyear, block-buy, advance-procurement, and economic-order-quantity tools for mature work; require an interruption-impact and replacement certification before a proposed pause or material rate reduction. | Service acquisition executive / Navy comptroller / program executive | Annual budget certification and each multiyear or interruption decision |
| R-24 | The final approved hull differs materially from the concept arrangement. | High | Major | Keep technology standards, interfaces, data, test methods, logistics, and insertion ladders hull-independent while performing complete class-specific integration and certification on the final design. | NAVSEA design authority / chief engineer | Requirements baseline, preliminary design review, and critical design review |
| R-25 | A developmental technology becomes a hidden prerequisite for ship construction or fleet acceptance. | High | Critical | Require a funded fielded baseline, explicit development ladder, off-ship test, certification gate, and retained fallback until the successor is accepted, producible, supported, and stocked. | Chief engineer / test authority / DLA | Technology insertion and production-start authorization |
2. Risk Acceptance Rules
- A critical risk cannot be hidden inside optimistic cost or schedule assumptions.
- A fallback reduces program consequence only if it is funded, designed, and testable.
- Modularity reduces redesign scope; it does not eliminate integration, shock, safety, software, or certification work.
- No developmental system may delay the first steel cut when an approved mature fallback exists.
- Risk closure requires evidence. A meeting, promise, or contractor forecast does not close a technical risk.
