I recall that around the time of AAC, or lightly after someone calculated that the minimum size of a CLAC that uses internal bays like existing types is around four megatons, any smaller you have to go longitudinal or external. Something based on a Nike with a couple of internal service bays could probably move a LAC squadron, and still be fairly tough and have some tubes, but a fast freighter mod would be cheaper, and for a bit more you'd still get the Nike.

they are not repeat not repeat NOT sticking outside the hull.

Now that we have more detailed info, lets redo the calculation. From HoS a gryphon class SD at 8.339M tons and 199M wide. The Shrike B is 72M long.

On a DN or SD LAC carrier, With lac's stacked 3 high and 30+ wide, the service and loading area must be between the LAC's and at least 10M wide. That means that minimum width would be 156M. If ship proportions are the same, then the minimum size for a CLAC would be 4,017K tons

But we don't need to have LAC's opposite each other with the loading and service machinery in the middle like they are on a DN CLAC. In the case of a BLAC, with one LAC high, we can have the LAC extend the entire width of the hull, with the loading and service machinery above and below the LAC. On one side would be the the door, on the other side would be sidewall armor.

With a 72m long shrike, the minimum width of a BLAC would be 74m wide. HoS lists the Proselyte-class heavy cruiser as Mass: 477,250 tons Dimensions: 607 x 73 x 61m. This would make a 497K ton ship 74M wide, plenty of room for a shrike that is stored running from the port armor to a starboard door or vice versa.

Edit: note: a 500K ton ship would not have enough internal volume to carry more than 6 LAC's and all their support equipment and supplies.

I was misinterpreting how Darrel was nattering on about the offsetting, his original image looked pretty much like a vertical repesentation.

And actually, the LAC's are not fully enclosed in the DN/SD CLACs, or at least not the Manticoran CLAC's. Their service bays "clamp" around the bows, just far enough to encompass their launchers. That's how the DN's can keep their reactors in the exact centre of the ships, without displacement.

Well your math is off, because a 3 high by 30 wide broadside of LACs is 90 LACs, for a total of 180 LAC's. That's more than 50% more LACs than Minotaurs carried (100), and a little less than 50% for the GSN Covngintons (124). And it's also about 25% less than what a RHN Aviary can carry around, at 250+. If you split total LACs carried in half for each broadside, that means even a Covington only requires around 62 bays per side. If you arrange the bays onto 3 decks, pretending the LAC bays were the grasers and missile tubes they replaced you'd only require 21 bays per line.

Shrikes are 20m wide, plus their bays will add at least 5m per LAC, so a total of 525m of each broadside is devoted to just the LAC bays, and the Minotaurs are 1184m from bow hammerhead to stern. Isn't it something like 20-30% of a warship is just the hammerhead flares? 1184 * 0.7 = 828.8m for the core hull, and with the PDLC's and CM tubes padding the broadside size a bit 550 & change for 21 bays + CMs and PDLC's actually sounds pretty close to bang on without crowding too close to impeller rings.

Covingtons managed their slightly increased LAC loadouts, while also being slightly shorter than the Minotaurs, at a total length of 1135m and also managed to squeeze in a couple broadside lasers to boot (somehow). I'm assuming they must have put some things a little closer to the impeller rings than the RMN was willing to accept.

I checked HoS. None of the CLACs mount any broadside lasers. Only the Minotaur has any chase energy weapons - the follow-up Hydra and Covingtons didn't even have those.

Also, the Minotaur is 1131m - so the Covington is larger. The Hydra went smaller than the Minotaur - barely, at 1129m. HoS also states that the Hydras cut their chase magazines in half(on top of deleting all grasers). The implictation is they shortened the necks between the main body of the hull and the hammerheads.

Is it in the House of Steel thing for the Minotaur being 1131m? The original Minotaur CLAC testbed
Echoes of Honor, Ch 3 wrote:masses just under six million tons, with an overall length of two point two klicks and a maximum beam of three hundred and sixty-seven meters.
And then the wiki states the rest of the Minotaur class were 1184m length and 189m beam, so almost a 50% size reduction from test bed to production model.

And I have to amend my previous post, DN/SD CLACs do fully enclose their LACs. The only important part of their bays is the support cradle and the bow assembly that clamps around the docking tube, graser, PDLC's and missile tubes for maintenance ease and rearming.

Anything smaller than a BB cannot fully enclose a LAC, without dangerous offsetting that can make them more vulnerable to dangerous blowouts. So the absolute minimum has to be to enclose the bows to allow maintenance and rearming, plus some support assembly to brace the LAC whenever they're not needed in space.

EoH is pre-great resizing so dimensions in it got retconnened when Honorverse ships all got resized to something more appropriate for their tonnage, as previously SDs had about the density of a blimp

It wasn't quite that bad. The density of Styrofoam, yes, lighter than air, no.

After the great resizing, the Minotaur is about 18% the density of water. Before the great resizing, the Minotaur was about 2% the density of water, and you would need to have a density that is less than than 1/22 of one percent to be lighter than air. :D

I seem to recall textev from EoH where they described the decision to a DN-sized hull for the LAC Carrier rather than a BB-sized hull for the prototype (HMS Minotaur). I think it came down to Adm. Adcock stating that since they already planned to build DN-sized hulls for the ships off the assembly line, they might as well go for a full sized prototype.

Ultimately, my sense has been that dreadnoughts are going the way of the dinosaur in the Honorverse, as they were always a way to save money while still building ships-of-the-wall that could at least give proper superdreadnoughts a serious fight. At the beginning of SVW, some 90% of the Havenite wall-of-battle was SDs while only 60% of Manticore's was SDs (the rest being DNs). At the beginning of AAC, there was a debate about building DN(P)s and it was deemed not worth the time and money to design one, work out any design flaws and problems, setup the necessary assembly lines and then start building. It was simpler to keep on building the SD(P) which they would need to build anyways. So for Manticore at least, DN-sized hulls are the ships of choice for CLACs while Haven seems to prefer SD-sized hulls for theirs.

Regarding the SLN, they are so far behind the curve that they are where Haven was when the first war broke out. They would first need to divert the necessary resources, at the federal level (which is going to be a serious fight for the limited federal budget), to R&D and start figuring out a whole host of Manticoran advantages, including (but not limited to) miniaturization of components for missiles and ships, fission piles, dual- triple- and quadruple-drive missiles, the new compensators, the FTL communication system, the bow and stern walls (and buckler stage) and the new beta nodes. Then they'd have to build prototypes and work them out. Then they'd need to develop the assembly line and start producing them en masse. Only then will they have the ships ready for trial runs and train their manpower (the one thing they aren't short on). It took Manticore (and Haven for that matter) over 20 years to develop all of these technologies. Even assuming it took the SLN less time to at least negate much of the qualitative advantage, I doubt the League has that time. Nor do they have the time to experiment with hybrid ship of the kind desrcibed here.
