🇺🇸 HAPPY 251st BIRTHDAY TO THE UNITED STATES MERCHANT MARINE! ⚓
Today, June 12, 2026, we celebrate 251 years of service, sacrifice, and maritime excellence by America’s Merchant Mariners.
The origins of the U.S. Merchant Marine trace back to June 12, 1775, when merchant seamen played a vital role in the struggle for American independence. During the Battle of the Margaretta near Machias, Maine, local patriots led by Jeremiah O’Brien captured the British armed schooner HMS Margaretta, proving that American merchant mariners were ready to fight for liberty long before the nation itself was born.
From the American Revolution to the present day, Merchant Mariners have transported troops, ammunition, fuel, food, and supplies wherever and whenever America has called. Their service has been indispensable in times of war, national emergency, and peace.
During World War II, President Franklin D. Roosevelt famously recognized the Merchant Marine as America’s “Fourth Arm of Defense,” acknowledging its critical role in sustaining military operations around the globe.
For 251 years, America’s Merchant Mariners have remained the lifeline of our nation—supporting commerce, strengthening national security, and answering the call without hesitation.
Fair winds and following seas to all who have sailed before us, those serving today, and the generations yet to come.
⚓ “The Merchant Marine has always delivered.”
