Is that something like 40% of all carrier groups?

This site shows 6 carriers at sea, 3 in port and 2 in the shipyard for maintenance.
Interesting. Navy/USMC air together is roughly the size of the entire Russian Aid Force. US Army air is larger. The USAF alone easily dwarfs Russia. China not even close to Russia.
Underway is not the same as deployed. GW is currently conducting “Carrier Quals” for pilots based at NAS Oceana, as well as various other training, certs and quals.
If it were not for the US Navy, the world would look very different for Americans.
