This flag is the US First Navy Jack: (a copy is purchasable here)
The history of the Navy Jack is narrated here. The Navy Jack is displayed when the ship is in port, and on special occasions. On May 22, 2002, all US Navy ships were ordered to fly the Navy Jack in lieu of the Union Jack for the duration of the Global War on Terrorism (GWOT).
This is the Union Jack (from here:)
The Navy Jack seems to me a very apt warning to al Qaeda and its allies.
It may also be a means of knowing when the end of the GWOT is official.
