Navy 2025 Shipbuilding Plan Summary

• Fleet Expansion: The plan aims to grow the navy fleet from 295 ships in 2024 to 390 by 2054, though it projects a temporary decline to 283 ships in 2027 due to retirements exceeding commissions.
• Cost Increases: Annual shipbuilding costs average $40 billion (inflation-adjusted), marking a 46% increase compared to average appropriations from the past five years. CBO estimates total costs at $40 billion annually, while the Navy’s estimates are $30 billion.
• Operational Readiness: The fleet's firepower will decrease in the near term but increase thereafter. However, maintenance delays may limit deployment readiness unless addressed.
• Ship Types: The plan emphasizes building more smaller ships, unmanned vessels, and Virginia-class submarines. It also involves additional funding for Columbia-class ballistic missile submarines.
• Industrial Base Challenges: Current delays and workforce shortages strain shipbuilders. Costs for programs like carriers and submarines exceed estimates, necessitating investments to maintain production schedules.
• Budget Implications: A larger fleet requires a $2.5 billion increase in the Navy's budget by 2054, potentially lifting total funding to $340 billion annually from $255 billion today.
