Celebrating the 250th Birthdays of the Navy and Marine Corps at their Birthplace

As the United States prepares to celebrate the 250th anniversary – the Semiquincentennial – of its Declaration of Independence in 2026, we should celebrate in 2025 the creation of the military services that enabled and defend our independence. Homecoming 250 Navy Marine Corps is a non-profit created by numerous individuals and organizations to host the main 250th celebrations of the Navy and the Marine Corps in their birthplace: Philadelphia and the Delaware River.

Our “Launching the Semiquincentennial” plan has generated great enthusiasm in the Navy, the Marine Corps, the Delaware Valley and beyond. It is endorsed the Governors and Legislatures of Pennsylvania and New Jersey, the Mayors and Councils of Philadelphia and Camden, the Congressional delegations of Pennsylvania, New Jersey, and Delaware, and by fourteen Secretaries of the Navy. America 250 has made us a National Partnership Program.

The 250th anniversary of the Navy’s founding on October 13, 1775, will be celebrated in October 2025 by assembling for touring on both banks of the Delaware historical, replica, and active-duty ships representing every major war which the Navy has fought: the American Revolution, the War of 1812, the Civil War, the Spanish-American War, World War I, World War II, the Korean War, the Vietnam War, the Cold War, and subsequent conflicts in the Middle East. This unprecedented and spectacular exhibition of Navy history will include ships from the age of sail to the most sophisticated Navy vessels of today, with ships sailing in to join the unique and historic USS Olympia and USS New Jersey, the most decorated Navy ship afloat.


The USS Niagara at the Battle of Lake Erie on September 10, 1813. The Niagara will be one of the ships representing the sailing Navy during the commemorations.


The battle between the USS Monitor and CSS Virginia, also called the Merrimack, on March 9, 1862. A replica of the Monitor is planned to represent the Civil War Navy.


USS Olympia, Admiral Dewey’s flagship at Manila Bay, will represent the Navy of the Spanish-American War and World War I.


USS New Jersey firing a Harpoon anti-ship missile on March 23, 1983. New Jersey will be one of the ships representing the Navy of World War II, Korea, Vietnam, and the Cold War.

The 250th anniversary of the Marine Corps’ founding on November 10, 1775, will be celebrated in November 2025 by assembling on both banks of the Delaware ships with a special connection to the Marines, including amphibious and aircraft-carrying vessels. Most importantly, the Marines’ 250th will be celebrated at the recreated Tun Tavern, the Philadelphia waterfront tavern that was the birthplace of the Marine Corps. Tun Tavern will be recreated for the celebrations, will be operated by a charity, and will serve as a gathering place for decades to come.

Both celebrations will feature ceremonies, parades, aerial demonstrations, reenactments, and related historical, art, and science exhibits at Philadelphia’s historic sites and museums and on both sides of the Delaware.


The Navy’s Blue Angels, flying F-18s, will also participate in the commemorations.


These impressive 250th celebrations in October and November 2025 will provide exciting opening events for the Semiquincentennial, focus national attention on the 250-year history of the Navy and Marine Corps in their historic Delaware Valley birthplace, and celebrate those who have served our Country for 250 years.
