Eager spectators took to social media to post photos of the "Parade of Ships." If you're stuck indoors, you can watch ships pass the Statue of Liberty on Fleet Week's Earth Cam.

Some of the best shots came from people on the ships.
The U.S. Air Force posted their own photos on Twitter.
The ships will remain in the city over Memorial Day Weekend. Activities include parades, tours of the ships and military demonstrations. A complete list of events is available at Fleet Week's website.
