US Navy Sea Cadets march out of the room after posting the colors for the start of the Navy's 250th birthday celebration at the Puget Sound Navy Museum on Friday, Sept. 26, 2025.

The U.S. Navy and Marine Corps are celebrating their 250th anniversary with a lineup of events beginning this week and continuing throughout October and November.

A group of volunteers with ties to the Navy and Marines, called Homecoming 250, is putting on anniversary celebrations.

The Homecoming 250 events will be held in the Delaware Valley area at locations across Pennsylvania, Delaware and New Jersey. The festivities will kick off with an opening ceremony on Oct. 9.

The majority of events for Homecoming 250 will take place between Oct. 9 and Oct. 25, but several gatherings for the Marine Corps will also be held in November.

The celebrations come months after an extravagant festival and parade for the U.S. Army's 250th anniversary in June. Those events coincided with President Donald Trump's birthday and were put on by the Army. There are no similar White House-backed parades planned for the Navy and Marines. However, Trump spoke at a Navy birthday celebration in Virginia on Oct. 5.
