Less fuel and 120 times longer on station…..misprint or really big batteries and/or nuclear?
Has to be either a misprint, or someone not understanding what the requirement is supposed to be. IMO even a nuclear-powered vessel would not be able to have a x120 increase in the time on station, unless the time on station was originally only measured in minutes or maybe hours. The issue would being that there is both a limit to the victuals a vessel could realistically stock and store for the crew, as well as the limits of crew endurance.Less fuel and 120 times longer on station…..misprint or really big batteries and/or nuclear?
Agree it is an increase of 120% ..... I think the issues is the AB propulsion packages is built around for GT's and these are not the most efficient beasts. Perhaps they are looking at a hybrid system with electric drive and DG's in addition to the GT for power production. They may also go for combined cycle GT's that recover the heat for steam turbine gensets in addition to direct drive.Less fuel and 120 times longer on station…..misprint or really big batteries and/or nuclear?
The link a few posts back mentions IPS so this future ship is likely going to have something similar to what the Zumwalt class has.Agree it is an increase of 120% .....

Combined cycle GT's are being considered for cruise ships as the produce less carbon for the power generated and are more efficient in that role (not all) where large electrical loads need to be supported. In the cases of ships like DDG's the shaft of the turbine can still turn the prop (for sprint) but can also provide heat for a steam turbine generator. I am not saying this is what they are doing but these technologies exist and may be used to improve range.
A semi useful comparison is the range of the T26 (which is a CODLOG configuration) and the AB, there is close to 3000nm difference (depending on what reference you use) between the AB and the T26 to the latter's advantage. This may be because of the difference in the propulsion system. This does appear to come with a lower top speed.
It would be interesting if you could quad pack say the SM-2/6. That would mean 16 per VPM if you so desired it and say 16 modules per side with six of those having quad packed SM-2/6 is certainly a lot of SM-2/6 (96) per ship. It would still leave you with 40 cells for other missiles and you theoretically still have the 32 Mk-41 VLS on the foc'sle. Load 16 of the Mk-41 with ESSM Blk 2, there's another 96 SAM. I suppose dreams are free.While I accept what USNI says is what they believe it will actually turn out to be, and they may be right. But it’s not what is shown on the PP - just the 32 on the forecastle; between the funnels is where the “destroyer payload module” is intended to go. Presuming that is analogous to the VPM then yes, it provides more large dia cells; but the current load out of that is for land attack not AAW. Somebody with more knowledge than me might be able to say if you can (or will be able to) quad pack, or similar, an AAW missile in those cells. They do have 42 RAM, which no bad thing. It’s only a concept drawing of course; we may know more about actual load out in a year or so. Meanwhile the Monday morning quarterbacks, of whom I must count myself one these days, will be telling them what it ought to be in that time.
All speculation of course, but three things that come to my mind are, arrestor wire break, hook failure or a cold shot from the catapult.F35C lost in carrier accident. Pilot ejected 7 sailors injured, possibly wire break.

The fate of the F-35C, which was involved in a "landing mishap" while operating from the aircraft carrier USS Carl Vinson, is unclear.www.thedrive.com
Just to add my two cents worth, AFAIK even if the wire broke the pilot should've have been able to push the throttle through the fire wall and go around. As you say all speculation of course. The flight deck of a CV / CVN is a very dangerous place to work and carrier aviation is the most dangerous of all flying.All speculation of course, but three things that come to my mind are, arrestor wire break, hook failure or a cold shot from the catapult.
Firstly, I’d discount the cold shot, wouldn’t expect deck crew to be injured if that happened.
Secondly, if the hook broke you’d expect the pilot to apply power and continue on as if it was a bolter, eg, a missed wire.
Lastly, a broken arrestor wire sounds more likely.
Again, just speculation of course.
If the wire breaks after already partially slowing the aircraft it may well be too slow to fly by the time it reaches the front of the angled deck, regardless of afterburner. Only option then is ejectJust to add my two cents worth, AFAIK even if the wire broke the pilot should've have been able to push the throttle through the fire wall and go around.

The video leaves a lot of questions, but I would say it doesn't look like snapped wire or hook, just a bit to much smoke. And the images of the plane in the water pretty much shows it didn't break up on the deck
Sounds like he came in low and lost his undercarriage to the round own. Debris from that would account for deck crew injuries, and a belly slide for some of the smoke (Wild ass guess warning)Due to pilot's mistake, the aircraft landed early on USS Carl Vinson (CVN-70) Aircraft Carrier and slipped into sea with severed landing gears!
I would think sticking with the current guns and using inexpensive dumb rounds might be a better option than a single 16 inch gun. Modification cost for hypersonic missiles would probably be less expensive and certainly more effective. This is being planned for now.Just asking on the Zumwalts theoretically could the gun mounts accommodate one 16" barrel from the old battleships.

No, no, no.I would think sticking with the current guns and using inexpensive dumb rounds might be a better option than a single 16 inch gun. Modification cost for hypersonic missiles would probably be less expensive and certainly more effective. This is being planned for now.
