You Don't See That Very Often

Lets assume the official site is telling the truth.

Ships Underway

Carriers:

USS Enterprise (CVN 65) - 5th Fleet
USS Nimitz (CVN 68) - Pacific Ocean
USS Dwight D. Eisenhower (CVN 69) - Atlantic Ocean
USS Abraham Lincoln (CVN 72) - Pacific Ocean
USS George Washington (CVN 73) - Atlantic Ocean
USS Harry S. Truman (CVN 75) - Atlantic Ocean

Amphibious Warfare Ships:
USS Nassau (LHA 4) - Atlantic Ocean
USS Peleliu (LHA 5) - Pacific Ocean
USS Wasp (LHD 1) - 5th Fleet
USS Essex (LHD 2) - South China Sea
USS Kearsarge (LHD 3) - 5th Fleet
USS Boxer (LHD 4) - Pacific Ocean
USS Bohomme Richard (LHD 6) - Pacific Ocean
USS Iwo Jima (LHD 7) - Atlantic Ocean
USS Denver (LPD 9) - Pacific Ocean
USS Juneau (LPD 10) - South China Sea
USS Tortuga (LSD 46) - South China Sea
USS Rushmore (LSD 47) - Pacific Ocean

That would mean the Stennis, Roosevelt, and Vinson, all three of which are either in dry dock or under nuclear conversion, and the Bataan which is in dry dock, are the only CVNs, LHAs, or LHDs not at sea. The only LHA not listed in the Tarawa, and it deploys today.

In other words, according to the official Navy website, over 75% of the carriers, 90% of the LHA/LHDs, and 66% of the nations submarines are at sea. You don't see that very often.
