How close are we to WWIII?

[GO-NAD!]

The Gerald Ford has a cruising speed of 30 knots, and can be pushed a bit faster. So that is about what a lot of speedboats do. A really good hydroplane could go faster, but not for long, and not at sea.

The reason these large aircraft carriers have a high efficient speed is because of their length. Maximun efficient speed increases with the length of the ship.


Hull speed can be calculated by the following formula:

vhull≈1.34×LWL X the square root of the vessel length.

where

LWL is the length of the waterline in feet, and vhull is the hull speed of the vessel in knots
Note that the 1.34 is not a dimensionless constant.

If the length of waterline is given in metres and desired hull speed in knots, the coefficient is 2.43 kn·m−½. The constant may be given as 1.34 to 1.51 knot·ft−½ in imperial units (depending on the source), or 4.50 to 5.07 km·h−1·m−½ in metric units, or 1.25 to 1.41 m·s−1·m−½ in SI units.

So in essence efficient cruising seed increases in proportion to the square root of the length of the vessel.

Long enough and no hydroplane is required!

She may be able to cruise at that speed, but her escorts can't. So, she won't. The main benefit of high speed capability is to assist with launching aircraft.

That is true as the escorts are shorter vessels.

Not just that. The Ford-class propulsion plant develops about 4X the shaft horsepower of an Arleigh Burke-class destroyer. A favourable length to width ratio only gains you so much efficiency. It's still a lot of weight to move.

Plus, while a CVN won't have to worry about running out of fuel, an Arleigh Burke won't get very far running at a continuous 30+ knots. Sure, they can refuel at sea, but that replenishment ship can't do much more than 20 knots flat out. And, even if they could do 30, they simply won't be conducting a RAS at that speed, as that would be foolhardy.

So we should also stop listening to you as well, after all, you are RETIRED.

As to being paid, in effect lie according to you, you must have serious evidence, right?
How many carrier battle groups deployed right now?

Now you get it!

No, not "in effect lie" - never said that or made that accusation. You connected the two. However, if you think just cause some Admiral or General was in charge of something at some point in life has anymore access to to CLASSIFIED information than you or I, I can assure you they do not.

I'm merely pointing out that we have more "stuff" to kill people than you think. If that makes you uncomfortable, not sure what to tell you. That disparity between our defense budget and everyone else's isn't for pop tarts and lollipops. it's to LOCATE, CLOSE WITH, and DESTROY our enemy. How it's used and by whom is decided by our elected officials. Pick better politicians if you don't like them getting us in stuff like this. (I was in Iraq, twice looking for "weapons of mass destruction" and in another country under a different administration trying to teach zealots that instead of stoning their children to death, they should learn to read/write - both were failures.)

My god.

Why hasn't our Navy been notified of this problem!?!? Who else knows that our aircraft carriers aren't being supported by their battle group!?!? Hasn't someone planned for this?!?!

Guys, relax. ZERO chance there are issues with our Navy and how fast it gets somewhere. Unless you been on one and ONLY if you were in very select spaces, you have NO IDEA what our ships are capable of.

That one has been there for a while with Lincoln. George Washington is in Japan area.

Sorry, the Geo H W Bush will be going, having finished its training.

Speed is great, stopping is the problem.

I never said there were issues with your Navy. I was just explaining why an aircraft carrier battle group can't cruise at 30+ knots, regardless of what that carrier can do on its own. So, as it pertains to these formations, I couldn't be more relaxed.

Oh, and one more thing, bounding along at 30 knots degrades sonar operating conditions. So, they could easily miss detecting a meanie submarinie laying in their path.

Or a mine field. Easy enough to deal with inaccurate SONAR from the sub- they can drop SONAR bouys.

EVERY war is expensive, my worries are the human toll of our soldiers. We have been pussy footing around with Iran longer than much of you on this forum can even remember, perhaps now is time to remember the words of Conan.........

'Crush your enemies and see them driven before you and hear them lamenting, oh the woman'

 

[GO-NAD!]

Well, minefields are sown close to land, so there would be absolutely no reason to be doing 30 knots. Depending solely on sonobuoys dropped from aircraft, because your ASW ships are moving to fast for their sonars to pick up possible submarine contacts is like covering an eye and an ear and saying "meh, that's good enough". That would be hubristic and foolish. And, they would go through a lot of sonobuoys.

Iran has, apparently, placed mines farther from shore- goes with their thinking that they can harass vessels that are on international water.

The aircraft carriers can't go faster than the slowest vessel.

Well, it can but it won't.

Why do you need to look past the reason for my comment? Of course it's able to, but for the operation, no, it can't.

Geez, this is how our English teachers tried to correct us when we asked "Can I go to the restroom?" by asking if we were able to. "Yeah, I'm able to and if you don't let me, it's gonna happen right here and now".

This is now serious. The US Navy say they will not escort ships through the Straights of Hormuz as it is too dangerous. Iran has now mined the straights.

Two ships that tried to run the straight have been attacked. One is badly damaged and on fire. Three crew missing. The other less damaged. But worse, another ship was damaged by Iran in the Arabian sea.

This is now serious as it is not only oil, but container ships going to and from Europe are also in trouble and one has already had to run the straight, but I doubt any more will try it.

The new supreme leader, has been "lightly" injured in an attack. However, he has not been seen, and Putin claims to be in contact with him.

Trump says Iran has no more weapons left, but they have just attacked a refinery in Oman and there is a large fire.

The most worrisome fact is that that we have a demented lunatic in the White House.

Brent Crude right now is $92.51 per barrel and rising fast.

I don't think it will be long before oil goes well over $100 per barrel.

Natural gas prices. What is worse is that it is in short supply and causing problems in electricity generation. Because of emissions most base load electricity generation is from natural gas, especially in Europe.

The green lobby has stopped all gas and oil extraction of the UK North Sea coast and wells are capped.

I think the UK for one is very close to electric supply interruptions.

I expect natural gas prices and electricity prices to spike in the US also. The reason is that the well heads in Texas in particular sell to the highest bidder. Bulk gas carriers bound for the UK, are filling up in texas and not the Middle East at this time.

My view is that Trump's adventure is going to cause massive world wide disruption, which at this time is just at the beginning. If there continues to be degrading of energy infrastructure, then disruption could be prolonged.

STOP PRESS: - Iran now says it will strike oil facilities until oil prices reach $200.00 per barrel.

Trump however claims they have nothing left to fight with. I doubt that is true after attacks today. Stopping these attacks will take boots on the ground in my view.

Meanwhile Putin is "Smacking his chops" as he knows darn well Europe will be forced to buy Russian oil.

 

[TLS Guy]

IEA has agreed to a release 400 million barrels of oil to ease markets. Most think this will not help much as it is four days supply!

And he said the Navy escorted ships until the post was removed and denied by the news secretary.
It is until it is not.

ps. maybe he should do an executive order forbidding the sale to highest bidder.
oh, wait the oil barons are his buddies, no?
