A sampling of antiquated components used aboard the Seattle-based Coast Guard Cutter Polar sit on a workbench in the cutter’s engine control room while the cutter undergoes depot-level maintenance in a dry dock facility in Vallejo, Calif., April 16, 2018. The Coast Guard faces challenges with repairing components on the cutter, commissioned more than 40-years ago, due to the inability to locate and replace the aging and obsolete parts.
