Roland: 188,750 tons
Average LAC: 21,000 tons

1 Roland = 8.9 LACs

For the sakes of simplicity, I'm sticking with the Shrike-B/Ferret mix.

9 of those would have a collective 72 CM and 108 PD. How would the double stack of 24 missiles fare against this defensive umbrella?

As for the Sag-C, at 483ktons, the ratio stands at 1:23. 184 CM and 276 PD - and the Sag-C can quad-stack up to 160 missiles.

What about the mighty Nike BC(L)? Well, it can quad-stack 200 missiles. But its weight in LACs comes to 120. That's a staggering 960 CMs and 1440 PD!

Plus the LACs also have excellent stealth, bow/stern walls, the best acceleration and maneuverability, Ghost Rider decoy missiles and EW... all to offset the fact that any single hit will be a kill.

The Roland will be facing 36-missile salvos. Sag-C, 92 missiles. Nike, 480. Well, assuming every LAC survives into their missile range, which they wouldn't.

IMO, the likely outcome of any of those scenarios would be mutual slaughter. The Roland might run out of ammo if the LACs feints a few times and the Nike might end up eating a few dozen grasers with its magazines nowhere near empty.

Really bad idea. You´re going for the blingfactor, exactly what you should NOT do.

Adding more missile control than REQUIRED is definitely a big no-no unless you want to pay for a much bigger ship than you need 99% of the time.

Hmm... No. Trying to guarantee that in a design is going to skew it enough to make it expensive and not good enough for its primary missions.

And even combat focused ships often have trouble fighting their tonnage equal in LACs.

It'd be awesome if it were free. Or so cheap you could get it without compromising either (1) what it needs for its standard missions, or (2) the various price-tags it has to come in under to be the workhorse cruiser. But yeah, I don't think that's going to happen either.

That requirement to be able to eat up large quantities of LAC's sticks out badly among other proposed mission requirements. Satisfying the rest of them jointly isn't too troublesome. They're all a matter, essentially, of building a counter-piracy drone-tending warship that can take care of itself against peer combatants. This one is being able to face off against a comparable tonnage of warship that has no care whatever for alpha nodes, hyper generators, boat bays, drones, deep magazines, or Marines.

For that, you'd better be a LAC or a fortress yourself, and either one of them is utterly unlike what a cruiser is.

semi-unnested the quotes and further snipped. (And now I see munroburton already made the same basic point -- got to stop writing and posting responses before making sure I've read all the new posts)

Jonathan_S wrote:That last is probably asking a bit much. The LACs have a much higher percentage of their displacement dedicated to weapons because they don't have to 'pay' for hypergenerators, alpha nodes, supplies for months of cruising, etc. So an equal tonnage of LACs should have a significant advantage in weapons tonnage. Given roughly equal tech levels that give advantage to the LACs.

I don't disagree that the cruiser needs to be capable of defending itself from LACs - just that it's probably no realistic to stand up to an equal tonnage of them.
Disagree, though respectfully. The only reason Minotaur's LAC wings survived was that the PN didn't know they were there, nor their capabilities. So they reached a winnable ambush range in combination with the other forces.

An equivalent weight of LACs would never survive to reach attack range against an alerted RMN cruiser; even a PD1921 Roland-class DD would wipe them from space.

Respectful counter-point. Each Triumphant-class BB massed 4,493,250 tons [per Jayne's]. An equal tonnage of Shrikes is more than twice Minotaur's entire brood (4.5 mtons / 20k toms ~= 220 LACs per BB).

So those BB's weren't fighting an equal tonnage of LACs; instead they had a tonnage advantage of over 69-to-1 ("Thirty-plus battleships" vs "the ninety-six LACs which had launched from the big carrier").

But if those 30+ BBs had run into a swarm of 6,600+ LACs? The LACs don't really need surprise anymore, the BBs are toast either way.
That's why I say defense against an equal tonnage is way too large an ask.

the new (well new-ish) generation of LACs are, ton for ton, the most dangerous ships in space.

It was only pre-Ghost Rider days that LACs were relatively harmless, and look what just three of them did to Honor's 'squadron' in Yeltsin during HotQ. McKeon's Troubador got hammered, and if they'd gotten any closer even Honor's Star Knight Fearless could have gotten popped. That was at 1:1 hulls, and I'm not even going to try figuring what the actual tonnage differential was.

As little as two squadrons, heck even just one squadron of modern Manticoran LACs (excluding Katana's) is basically a death sentence to anything sub-waller. To extend Jonathon's reference, we had textev in either Echos, or the next one. That a Captain Steward (then just a Lt.Comm) commanded a LAC that personally killed outright two Triumphant-class BBs, not just lamed but killed. His squadron as a whole, nailed... I think it was five? maybe six? I'll track down the quote.


To add sufficient firepower, or threat there-of, to a cruiser to potentially dissuade a single LAC squadron is already pushing a heavy cruiser's firepower into beyond old-style battleship's firepower.

Stewart's LAC did not singlehandedly kill two BBs. What it did was deliver the killing blows - those BBs had been chewed up by missile and repeated graser attacks.

As to adding sufficient firepower to kill LACs; the RMN already has the Viper countermissile. The Wolfhound or Avalon would be better suited to anti-LAC screening duties than DDM units - their LERMs require less magazine volume, smaller launchers and can cycle faster, all while still slightly outranging LAC missiles.

My only quibble with that, is... aren't countermissile launchers generally the same regardless of the unit it's mounted on? So a destroyer that gets built in say, 1920 PD, and a superdreadnought built the same year, both ships would have the same CML, just different amounts in each hull.

Although.... thinking about it, Viper anti-LAC countermissiles, being loaded shotgun-style on the tip of a standard LERM? Would that even work... basically just a variant on the very old counter-missile canister concept.

"Skipper! Ghost Rider drones report a LAC swarm inbound at..."
Commander whoever: "Tactical, load anti-LAC missiles, and sound battlestations"

Well, actually it'd be a cross between the CM canister, and those Technodyne Cataphract missiles with the sprint-mode at the end of the run. Could probably pack 4 or 5 CMs into the same space as a shipkiller warhead+seeker takes up.

That's why I specified that outside of an ambush, it wouldn't happen. Consider that if a LAC weighs 20K tons, that's 9 LACs to match a Roland's weight vs 250 shipkillers. With the Sag-C, 24 LACs, vs. the number of missiles a Sag-C can drop and throw

Do you really think 9 or 24 LACS would survive multiple DDM launches at about maybe 10x their own missile range (the LAC shipkillers have to be pretty short legged), given the LACs also they'd need to stay somewhat clustered for mutual defense, making target acquisition even easier...

Against the RMN pen-aids and missile seekers, and an alert and highly competent Tactical section on the cruiser? I personally don't think so.

It's 72 CM and 108 PDC's against 24 DDM's at a time. Assuming comparable electronic warfare quality and skills (though, granted, the single larger unit may concentrate both a bit more), then yes, the idea IS that those 9 LAC's will survive multiple DDM launches, just because each 24 DDM salvo will generally fail to penetrate those active defenses. They're just too thick. The Roland is effectively counting on a golden BB - not to penetrate armor to something vulnerable, but to get past all the active defenses. (And, to a lesser extent, wedges, evasive maneuvers, and walls all around.)

Granted, outside an ambush, the LAC's may not be able to reach the Roland before it vanishes into hyper, either with empty magazines if it tried to engage or with full ones if it didn't bother.

It may come out differently if the Roland can stack a much larger salvo with rotating control channels and a staggered delay firing sequence. But then you've got worst accuracy and running the magazines dry becomes a still worse issue.

It may also come out differently in case of a light cruiser design with much deeper magazines, that's effectively using initial salvos to trade its own shipkillers for LAC CM's, and then face only the PDC's for the final salvos. It's maybe one of the better excuses for really deep magazines on a light combatant.

(I wonder too if this sort of thing may argue in favor of dual-drive Viper's - huge, granted, but their combined anti-LAC, anti-missile, fire-and-forget, very long range, very high speed, and extended missile defense capability may make them worth it. Replacing some of the shipkilling and some of the standard CM launchers with some for those on light combatants - at whatever ratios would apply - could give them a new niche in fleet combat compatible with their other missions.)

Seriously though, if you want to destroy a lot of LAC's, better to send a battlecruiser or at least load up heavily on pods. Either way, it's not the sort of mission for a workhorse cruiser.

You're ignoring the anti-missile capability of the LACs. As I already pointed out, the 9 LACs can counter each 24-DDM salvo with 72 CMs - exactly three CMs per missile. I can't remember how fast CM launchers are exactly - but they're considerably quicker cycling than shipboard launchers, whether SDM, DDM or 3DM. So the LACs have time, at longer ranges, to get multiple CM salvos off. 72 becomes 144 becomes 216.

The clustering isn't really an issue - missile attack ranges being <50,000km, every single ship in any fleet is within missiles' range baskets. If anything, the LACs can tumble around each other along with their decoys, confusing the missiles targeting them even more.

LAC missiles are roughly the size of pre-war CA/BC missiles going by this: http://vignette2.wikia.nocookie.net/hon ... 0211142025

You can see how the current gen RMN missiles compare to each other here: http://maxxqbunine.deviantart.com/art/F ... 7746&qo=69
Countermissiles here: http://maxxqbunine.deviantart.com/art/C ... 7746&qo=71

I would be very surprised if the LAC missiles couldn't provide powered ranges of at least 8 million km.
