The announcement was made during an annual speech to the French Armed Forces.
Speaking aboard the nuclear-powered vessel on Wednesday, Hollande said the deadly attack on French satirical magazine Charlie Hebdo last week "justifies the presence of our aircraft carrier."
"Thanks to the Charles de Gaulle we will have intelligence," said Hollande, adding that "we may also conduct operations in Iraq."
Any such airstrikes would be undertaken under Operation Chammal, the French contribution to the U.S.-led multinational Operation Inherent Resolve.
The Charles de Gaulle is expected to be deployed until at least May.
