Several days ago we reported on the news that the USS Nimitz and Carrier Strike Group 11 (CSG-11) were ordered to return home to San Diego after finishing a seven-month deployment. Because of restrictions regarding COVID-19, to ensure crew readiness prior to deployment, the crew had been isolated from their families since April. The Nimitz CSG was operating off Somalia with the Makin Island Amphibious Ready Group (ARG). According to the Navy, their mission was to support the repositioning of some 700 U.S. troops from Somalia to other countries in East Africa.

After that mission was accomplished, the Nimitz and her escorting vessels, the Guided Missile Cruiser USS Princeton (CG-59), the Guided Missile Destroyers USS Ralph Johnson (DDG-114), USS Sterett (DDG-104), USS John Paul Jones (DDG-53) and one or more nuclear attack submarines, were detached and slated to return to their various homeports in Hawaii and the West Coast.

That all changed when Acting Secretary of Defense Chris Miller issued a statement on January 3, 2021. The terse statement was comprised entirely of this.

“Due to the recent threats issued by Iranian leaders against President Trump and other U.S. government officials, I have ordered the USS Nimitz to halt its routine redeployment. The USS Nimitz will now remain on station in the U.S. Central Command area of operations. No one should doubt the resolve of the United States of America.”

Of course, this means Nimitz and Carrier Strike Group 11 will come about and return to a patrol area in the Gulf of Oman or the Persian Gulf. Pundits were quick to announce that this move amounted to nothing more than saber-rattling or was a vanity move by President Trump. A few took an even more shrill tone claiming (without any real basis in facts) that President Trump intended to start a war with Iran to hobble the incoming Biden Administration. Some even made more outlandish claims about the U.S. starting a war with Iran to get Saudi Arabia to pay off private debts owed by President Trump.

While we do not know the precise nature of the threat referenced by Secretary Miller in his above statement, we doubt very seriously that it involves saber-rattling or any bluff and bluster on President Trump’s part. You see, cranking a Carrier Strike Group around 180 degrees and sending it back to the Persian Gulf is not something you do on a mere whim. Not after it’s been at sea for seven months. This order by Miller has significant second, third, and fourth-order effects. Such decisions are not made lightly.

The carrier and its escorts have to be supplied with fuel, food, and other materials to remain on station. This will mean tankers and replenishment vessels will have lengthened deployments and have to make quick turnarounds themselves wherever they return to port, resupply, and get back out to the Nimitz. Such supplies will have to be flown from the U.S. to the base of supply of the sustainment vessels responsible for the carrier group.

Sustained carrier operations are pretty hard on the 60 plus aircraft aboard the Nimitz. When Nimitz’s Carrier Air Wing 17 returns to shore, its planes are subjected to a rigorous inspection and rework routine on engines and airframes. This can be done at sea but it is not easy. Furthermore, delays brought about by flight operations increase the risk of losing aircraft and crews lost to a mishap.
