As the Coast Guard's participation in homeland defense gains momentum, the service will need new and more powerful capabilities to fulfill its vital role in helping to ensure U.S. security. A model improvement program for enhancing the capabilities of the Coast Guard's Hamilton (WFMC-715)-class cutters is the addition of newly upgraded electronic support measures (ESM) systems to detect a wide range of hostile threats to U.S. citizens, vessels, and property.
Threats to our interests are neither new nor novel. What is relatively new by military standards—and has gained prominence in the past 20 years—is the concept of an unseen and sometimes unknown enemy that cannot be identified with organized governments. In light of today's dangerous and confusing geopolitical situation, the Coast Guard's motto, Semper Paratus, has never been more relevant.
