Sailing by Starlight. How a carrier strike group operates.

Quantam navigation is the solution and both the UK and USA have prototypes afloat.

However the article in the op is describing what is happening now and not in a fantasy future. And they know what they are doing....

Quantum navigation - is that when you are both utterly lost and also know your position at the same time?

I did enjoy reading it. I didn’t say they were lying, I said that it seemed pointless using a human (who would be easy to spot on deck at night) to measure an angle and then use a computer for literally everything else. The military often leave out details for security reasons, especially when talking about tech. I’d assumed you were familiar with security clearance type stuff.
I thought it an interesting conversation but obviously you want the thread to go a different way, in which case perhaps you could guide us on what you consider a proper way forwards?

Not at all. Follow your nose.

They can just use their mobile phones to call...

They can't call 911, that's why they have all those guns onboard

 

[ducked]

With impunity, apparently.

Technically, you can know your speed or your location, but not both; unless you kill your cat. I think.

As I understand it, quantum nav is just extremely small, accurate, expensive gyroscopes but without the gyroscopes. The technique isn’t new but it’s hellishly difficult to implement, especially on a boat. Probably the modern equivalent of the chronometer, which itself was a huge lengthy saga

It's the 25 circling Cessna's towing 100' banners saying MAGA and 'Go Steelers Go' that will give their position away.

'Sailing by Starlight': How USS Abraham Lincoln is navigating Arabian Sea without GPS or radar

I still have my RN Ocean Nav certificate dating from an 1989 trip across the Atlantic stored safely in a folder somewhere, happy days.
Electronic silence The biggest issue now must be control of all those mobile phones.

The biggest issue now must be control of all those mobile phones.

Strava has been a huge issue for the US forces. All of the troops were wearing Garmin Tactix watches and recording their daily exercise then uploading the GPS tracks. Several bases were compromised before they realised.

Here's a wee bit of nostalgia...




Yrs trly being issued with a shiny new 21st century zero-emissions navigation system by HMQueen's Personal Representative. The sharp-eyed might spot that this occurred in Earl's Court.... back in the day.

Go deep.....

I was from the era before mobile phones so never had the issue. We still had a red box on the jetty.

And a red light in every window overlooking the jetty.

And no GPS required to navigate to the Mosquito Bar in Bangkok.

Interesting article but is the source one you know? WIONEWS is not one I recognise. A quick search says it is World Is One News, and is an English language Indian news source. Fact checking information is becoming a regular thing as not everything on the internet is true. However I did find another source that explains lots about the US Navy getting their ships to run quieter and there are further links to other information and another about navigating without GPS.

In 1980s Hong Kong I did a goodwill civilian visitor tour of a massive US carrier, too big to come in to the main part of the harbour. We got whisked out on a nice launch/tender/pinnace thing, and disembarked on to a pontoon alongside the ship. Then up in a big lift ( elevator) on to the flight deck oh man it was impressive. Then, deep joy, we got driven around the deck in a jeep! Those ships….
