At significant costs for crew retention.

Even if it's for an extended period, the carriers can be relieved one at time within the normal rotation cycle of the carriers.
I'm sure they can, but with 7 of 10 deployed, at some point you're going to run out of carriers to cycle through the rotation even if you extend deployments. Not to mention the current issues within the USN* regarding the sustainability of their Op Tempo.
Put it another way, if they could keep 7 out of 10 carriers at sea without any impact, why don't the USN do it all the time?

*Not that other navies don't have that problem either.

Because we don’t have the extreme instability that exists at the present time?

Or had that completely past you by?

Not at all, but as with most navies the USN appears to work on a 3 for 1 ratio of hulls, i.e. you need 3 to have 1 at sea. So one in refit, one in work-up, and one deployed. Unless there's a ridiculous amount of slack in that system I can't see how 7 from 10 works for anything longer than about 9 months, at which point you've run the sailors, ships, and aircraft ragged.
Still easy way to find out, wait until this time next year and see how many carriers are deployed.

.... maybe that's the NK plan, over extend the US capabilities by ramping up pressure continually....?

Really.. the only country able to put together a proper global enforcement task force.. and the best put down is can they keep it up for than afew months.. well I’m guessing if they needed to the yanks could.. more importantly they would..
Good to see at least one country on the planet is maintaining a decent navy..

Hmm you made sense with the not at all.

All after that however indicated that it had.

In spite of all the above mirth merriment and general jokes it should perhaps also be realised that with 7 carrier strike groups presently deployed the USN has at sea more ships and power than many country's Navies combined.

They also have about a century of carrier operations under their belt, and, at the present time just happen to be keeping the UK’s seedcorn carrier personnel trained and with the ability to man QE and the Prince of Wales in due course.
A joke: Leads the listener to expect a certain outcome, and at the last minute, another outcome is substituted.

Aah, one worthy of the BBC.

For 10 hulls, your ratio implies 3 in refit, 3 on work-up, 3 deployed and 1 somewhere in between. How is this significantly different from the status quo with 3 in refit (BUSH, VINSON, WASHINGTON), 4 on post-refit trials/work-up (STENNIS, TRUMAN, EISENHOWER, LINCOLN) and 3 deployed (REAGAN, NIMITZ, ROOSEVELT), not to mention FORD on acceptance trials and the new KENNEDY in build (link).

Don't confuse 'at sea' with 'deployed'. USS ROOSEVELT holds the record for the longest continuous period at sea by a nuclear-powered carrier (159 days) eclipsed only by the conventionally-powered HMS INVINCIBLE (166 days). However, foreign deployments can last up to 10 months overall and this doesn't include time away from the wall for post-refit trials & pre-deployment work-up.

Starting in November, Gortney said Wednesday at a Navy symposium in Washington, carrier strike groups will deploy once every 36 months on cruises that will be scheduled to last eight months. The longer maintenance cycle should allow for more consistency at home, Gortney said...

Last fall, the aircraft carrier Nimitz was ordered to extend its deployment and remain on station in the Red Sea as President Barack Obama contemplated a possible missile strike in Syria. That deployment ended up lasting nearly 10 months. Those sorts of extensions will probably still happen under the new deployment cycle, but they should be less common, said retired Vice Adm. Pete Daly, director of the U.S. Naval Institute and former Fleet Forces deputy commander and chief of staff.
