Objective
Develop a rapidly deployable logistic system
that provides vital fuel supplies to forces
ashore during the early stage of an assault.
Sea Cache

• Payoffs
• Enhance flexibility of logistic strategy
• Reduce beach support requirements
• Increase standoff distance of a seabase

• Summary
• Fits the culture of Seabasing concept
• Enhances fuel throughputs during early stage of
  amphibious assaults
• High sea state capable
• Technical feasible in design, production,
  operation, support, and dispose
• Cost justifiable
• Operation compatible with current logistic
  practice

• Recommendation
• Verify concept with large scale models
