Overhaul Delays for USS George Washington, USS John C. Stennis Partially Due to Unknown Steam Turbine Damage
USNI News ^ | 07/08/2024 | SAM LAGRONE

Posted on 07/09/2024 3:05:27 PM PDT by DFG

Extensive delays to the mid-life refueling and complex overhauls of two nuclear-powered aircraft carriers were due to damage to the steam turbines that power the ship, USNI News has learned. According to Naval Sea Systems Command, “significant damage” to the generators aboard both USS George Washington (CVN-73) and USS John C. Stennis (CVN-74) added unplanned work that was discovered after both carriers arrived at HII’s Newport News Shipbuilding for maintenance.

Every mid-life refueling and overhaul, “work package has planned inspections and routine refurbishment of the eight [turbine generators]; however, inspections for both George Washington and John C. Stennis revealed one generator on each ship with significant damage that resulted in unplanned growth work, which contributed to schedule extensions on both ships,” reads the statement from NAVSEA.

The Nimitz-class carriers mid-life overhauls are scheduled for four years, but Washington took almost six years while Stennis is set to take five and a half, USNI News reported last month.

Based on Fiscal Year 2025 budget documents, the Navy estimated the work would take an extra 14 months to complete the mid-life overhaul on Stennis due to the additional work.

In a statement to USNI News, HII said “the change in redelivery schedule for [Stennis] is primarily a reflection of growth work discovered after the ship arrived to NNS and subsequent challenges within the supply base … We are applying lessons learned from both George Washington and John C. Stennis to what we are doing to prepare USS Harry S. Truman (CVN-75) for RCOH.”

Steam is HOT.

Contributes to Climate Change.

Make those Nuke ships run on ice cubes.

DEI in the military is all good and fine during peacetime, but when you have a bunch of Hormone-Crazed Women running around trying to start World War 3 with Iran, Russia, and China, that crap is VERY COSTLY and may well drive the outcome of the war(s) they’re trying to start.

Those things are high maintainence. Are they worth it now that they can be harder to defend? I was thinking of how Russia’s navy in the Black Sea is doing.

Slow down there shipfitters. No need to rush the repairs.

Tell those gobs to quit emptying their bong water into the turbines.

Since we have aircraft that can reach around the world, could do more with non-nuclear missiles, carriers seem less valuable, floating targets.

Imagine how many unmanned aircraft we could fly, with pilots flying 9-5 almost literally from home in the US, to carry out the same missions?

They are worth it. The navy will adapt their tactics to defend them. Armed forces are constantly adapting and integrating new tsctics and weapons.

and worse

bad training makes it easy to damage those huge steam turbines...

complex lengthy exact series of events to both shut then down and start them back up

Sabotage is always possible. Aircraft carriers are massive, complex ships with large crews and many vulnerabilities. That said, turbine engine sabotage would require access to highly restricted engineering spaces and expert knowledge. Design defects and shipyard incompetence or defective materials seem more likely. For decades, the Navy has been blighted by poor shipbuilding design and build practices.

Hardly. They are obsolete dinosaurs. Ask the Houthis. The USN is being humiliated in the Red Sea. Wait until Putin sends the Houthis some Russian hypersonics and Russian “contractors” to aim and maintain them. That’s all fine, right? You know, like the NATO “contractors” and their ATACMS? The Houthis ended gunboat diplomacy.

“ The USN is being humiliated in the Red Sea.”

If the USN were turned loose on the Houtis there life expectancy would be measured in hours if not minutes. We don’t lack the capability, we lack an administration with the will to do it.

You’ve become nauseatingly predictable in your America bashing. Why don’t you trot back to that stupid inconsequential YouTube channel you were yammering on about before I got you kicked off the forum last time.

Sabotage? No doubt. Either ships crew or the nnsydd workers. Btdt. Seen nnsydd workers do damage to navy vessels under ovehaul. Either due to being forced to work overtime (omg!) Or just assholiness.

Big talk from the MIC stooges. Zero results. As I said, humiliated by a bunch of MUSLIMS hauling around their thousand dollar USN humiliators in the backs of Tacomas. Muslims, Muslims, Muslims!

I seem to remember Trump turning a few hundred Russian “contractors” into pink mist and greasy stains a while back. Putin did nothing about it.

So it’s not a matter of ability. It’s a matter of will.

A subtle distinction that is, of course, completely lost on a sub-80 IQ specimen like yourself.

Oh jeez. Why is a carrier named after a f***ing senator. Why is there no Lexington? Or Wasp? Instead we get the most corrupt politicians in history.
