The current generation USS Nimitz supercarriers (the largest ever built) require a crew of about 3200 sailors, and an aircrew of about 2500.

The next-generation Ford-class supercarriers reduce this number through automation by almost 20%, to roughly 4700 crew total.

For comparison, the prototypical WW2 aircraft carrier, the USS Essex class, had a total crew of 2600.
