Naval Ship Lifecycle Cost Calculator
Build a fleet-level lifecycle cost profile from acquisition through decades of operating and support spending, planned depot availabilities, modernization waves, digital sustainment and end-of-service costs. Simple mode gives a fast program screen. Advanced mode creates a year-by-year lifecycle schedule, present-value cost stack, availability burden, stress cases and cost-driver sensitivity.

Financial & Tempo Assumptions
Recurring Operating & Support Register
Annual per-ship cost by category. Each row can use its own escalation assumption. The register separates sustainment drivers that are often hidden inside a single O&S number.
| Use | Cost category | Annual cost / ship | Escalation %/yr |
|---|
Depot, Modernization & Lifecycle Events
Schedule major events explicitly. Costs are per ship and can carry their own escalation and planned downtime. A zero interval creates a one-time event at the first-year entry.
| Use | Event type | Cost / ship | First year | Interval yrs | Downtime days | Escalation %/yr |
|---|
Program Stress Cases
Stress acquisition, recurring O&S and lifecycle-event costs without altering the base case. Use custom rows for independent cost-growth cases.
| Use | Case | Acquisition % | Recurring O&S % | Lifecycle events % |
