$12 Billion = 4 days of QE spending. Chicken feed.
“Apologies to all for so much blather. I’ll try to do better.”
See, I don’t apologize for the blather. I made it my name. General Blather, rather than Specific Blather. That way I can comment on anything.
Basic problem: watts is instantaneous power, watt-hours is total quantity of energy. This launcher uses tremendous amounts of power but only over a very short period of time. That does not translate to “as much energy as needed to handle a city...”
!
Just what I was thinking - powers n homes for how long?
Other wise, the launcher running at full capacity consumes as much power as n homes, period.
And, watts are units of power, that is, a rate of energy transfer. Watt-hour is a unit of energy.
I have a lot of friends who worked on this ship. They were engineers. One worked on the steam plant, another with the propulsion lube oil, and another developing propulsion plant controls. The first ship of a class, is rarely ready for battle. It will go into a post shakedown availability and address these concerns.
This strikes me as a repeat of what happened with the USS San Antonio. Which a lot of people still don’t consider fully capable, given all the bugs and flaws resulting from the cutting edge aspects of its design.
The USN used to take a pretty evolutionary approach with ships. In the early part of the 20th Century it only built Battleships two at a time (sometimes three) to allow the technology to evolve. It should be noted that the eight Battleships at Pearl Harbor represented four different classes in and of themselves. The of the seven other Battleships that weren’t there, six of them represented ANOTHER three classes.
This continued until recently. The first nuke carrier - Enterprise, leveraged a lot of existing technologies so the only real issue was in integrating them. She was a modified Kitty Hawk class ship that was powered by eight small submarine-style reactors. She used existing arrestor and catapult designs, etc. The only real “revolutionary” aspect of her individual systems were her fixed phased-array radars ... which never really worked properly and were replaced during her late 1970s/early 80s refit.
Heck, even the first Aegis ships, the Ticonderoga-class, used the earlier Spruance-class hull.
It seems to me that, these days, there’s just so much of a gap between new ship designs that the designers go hog-wild to incorporate every new technology they can think of. So you end up with both new-tech teething problems AND integration issues. Rather than trying to mitigate the risk of one or the other. This is what happened with the San Antonio ...
What??? That makes no sense. Comparing energy to power is like comparing distance to speed. They are related but not interchangeable. The top part has 100 megawatts on a 6.7% duty cycle spread over 12,000 houses would be 555 watts per house continuously. That's reasonable. Then the confusion comes trying to expand that over time to larger cities. If you run it for 17 minutes it will still only power those same 12,000 houses for that time.
Also, the small "m" is for milli rather than mega. This definitely takes megawatts. I figured 34 megawatts for a fully loaded F-18, not including the mass of the moving parts of the catapult itself.
I cannot speak to that military issue directly, but our nation is running a TERRIBLE trade deficit in everything but military trade.
Looking at American production, we are sending far too much to China.
China now is the world’s largest exporter, and growing rapidly.
America we need to create stuff. Not just military stuff. All things need to be made.
Far too many, are now made elsewhere.
Bring back American industry.
What is the name of the 11th carrier?
Fraud, cronysim, and waste, donor hand greasing

Add in the Unions and you have a disaster on your hands. They have to be over paid, under worked, and need all those coffee and lunch breaks. So very little work gets done.
Gerald Ford....best republican president the democrat party could pick!!!!
Bingo!
I wouldn’t be surprised if after 5 years of trying to fix all its problems it is abandoned and fed to the fishes.
The same thing goes for the Saturn V moon rocket. It could not be built today for the same reasons you provided about Iowa class battleships, other lost, forgotten, technologies, skills.
I often see stuff like this and wonder, how do our “military - industrial people” and the WE MUST BUILD MORE crowd think China is going to pass us, when they are working on their first aircraft carrier. We built more than 100 during WWII and then came the nuke powered babies - not easy to beat in any time. Yes they, the Chinese are building, but there is a big jump from having a carrier and knowing how to go to war.
“Watts” are not consumed. The chart say, “In that time it can consume 100 m Watts.”
(BTW, ‘m’ in front of a unit means “milli-”, 1/0000. I think they they wanted ‘M’ for Mega, ‘million.’)
Power expressed in watts tells how much energy (in joules) is converted from one form to another per second. Or, in the English system one way of expressing energy is by how much energy in foot-pounds is converted to another form per second.
“Watts” times “time” is work or energy.
In other words, power is a rate that tells how rapidly you convert energy. You can’t buy or sell power, but you can buy or sell energy.
Our local energy cost is 12 cents per kWh. One kwh is equivalent to running one 100 W bulb for 10 hours, or 1.2 cents per hour.
Oops. milli- means 1/1000.
