Through prime federal contract awards, Mare Island Dry Dock has executed numerous high-value contracts across multiple agencies.

The most substantial is a $119.6 million single-award IDV with the U.S. Coast Guard for the Polar Star Service Life Extension Program, running from January 2021 through January 2026.
