Fleet availability depends on maintenance systems and supply chains as much as acquisition quantities.
Timeline
Development, procurement, fielding, modernization and sustainment overlap for major fleets.
A nominal fleet count does not show how many aircraft are available for assigned missions.
Watch audited readiness definitions, sustainment costs and corrective-action milestones.
What happened?
Oversight reports regularly examine mission capability, maintenance delays, spare parts and program support costs.
Why it matters
