Executive Summary
This thesis investigates density as a cost driver in naval submarine design and procurement, proposing it as an alternative to weight or size reduction for achieving lower costs. It argues that traditional weight-reduction policies often increase costs and that unnecessarily dense designs lead to higher cost, schedule, and performance risks. The research introduces new measures, Arc-permeability and Internal Density, to quantify how tightly systems are placed, identifying density as a significant, previously underemphasized factor in submarine cost growth.
Why It Matters
This document is crucial for defense and geopolitical analysts as it redefines cost drivers in naval submarine acquisition, impacting future fleet capabilities and strategic budgeting. Understanding density's role in submarine design directly influences procurement strategies and the long-term affordability of critical naval assets.
Key Takeaways
- Weight-reduction policies in submarine design often lead to increased costs, contrary to common assumptions.
- Unnecessarily dense submarine designs introduce higher cost, schedule, and performance risks.
- New metrics, Arc-permeability and Internal Density, can better explain historic submarine cost growth than traditional weight-based analyses. This allows for better cost estimation and design choices.
Strategic Relevance
This research offers a novel perspective on submarine acquisition costs, challenging conventional wisdom that links cost directly to weight or size. By identifying density as a key cost driver, it provides a framework for designing more affordable and flexible submarines, which is strategically vital for maintaining naval superiority and managing defense budgets effectively.
