Egyptian shipping sources said US aircraft carrier USS Enterprise crossed the Suez Canal on Friday coming from the Red Sea en route to the Mediterranean.
They added that the ship, which is the US Navy's oldest and longest aircraft carrier, was accompanied by a guided missile destroyer and a supply ship.
Shipping sources said Egyptian authorities tightened security measures on both sides of the canal to secure the ship.
The USS Enterprise carried 60 aircraft, weighing about 93,000 tons, according to the same sources.
It was not made clear whether the aircraft carrier was on its way to the Libyan coast to participate in NATO air strikes against Colonel Muammar Gaddafi's forces.
