The Admiralty knew about the gap in the armour but they delayed fixing it. These Battle cruisers were essentially prototypes.

That was actually Admiral Beatty's comment (and I've seen pretty convincing claims that the something wrong was the unsafe ammo handling practices he'd encouraged in his battlecruisers).

Note also that Hood was effectively a 5th generation of battlecruiser - the I-classes, the Lions/Queen Mary, Tiger (and Kongo, who'd inspired her changes), Renown/Repulse, and then Hood - and so probably the least prototype of all the battlecruisers. (Even if she was a big jump in size and armor over any of the earlier ones)

I still think a thicker CM zone is better. And the MAN is going to prove it when they make the LAC screen disappear. CM ships are still the best solution IMO.

Question. I vaguely remember that the ECM of the Dragons Teeth and the Dazzlers were found to be effective against enemy missiles as well. So why can't the fleet deploy them in hordes closer to the ships? Better yet, why can't the ships themselves activate the same electronic countermeasures? Ships have enormous power reserves. Unless the wedge and the sidewalls will hamper the transmission.

Um, they do. ECM and jamming, from the ships and from their towed decoys/ECM drones is already a major item in Honorverse naval combat. Recall this about Honor's GSN SDs at fourth Yeltsin
Flag In Exile wrote:Peep EW systems were inferior to those of the RMN. Getting comparable performance out of them required much more massive installations, and the Grayson Navy hadn't been able to resist the temptation of all that available volume when they refitted their prize vessels. They'd gutted their new SDs' original EW sections and then filled the same space with Manticoran systems, which meant Terrible boasted almost the same electronic warfare capabilities as a sixteen-million-ton orbital fortress, and that was just fine with Honor.
That electronic warfare is the ships' ECM and jammers.

But missiles expect that, and while it does cause some to totally wander off and never find a target, or to fire but miss, that's just part of the percentage game of missile combat and so doesn't get highlight in the battle description every time. (And missiles expect to face that and do their best to ignore, overcome, or home in on, that ECM/jamming coming from their targets)

OTOH a dazzler jammer had the (potential) advantage of going off behind the enemy missiles -- back there it can do a far, far, better job of jamming the fire control link & telemetry between the missiles and the ship that launched them. The antenna for that is mounted on the tailcone of the missile and would be highly directional; so it basically wouldn't be exposed to any jamming coming from its targets because they're all ahead of it. (And while that jamming would be heard by the launching ship's fire control links they're a lot farther away, reducing the signal's strength, and have a lot more computing power behind them to filter out the jamming from the data coming back from the missiles). But a dazzler going off behind the missiles is dumping that jamming noise right into that tail mounted fire control link receiver; and from far closer than the ship that launched them; quite possibly deafening them to anything the ship tries to tell them.

And so when a novel ECM approach (like using missile based ones) is used it get more description in the battle because it's novel -- but that doesn't mean that the ship mounted ECM/jammers aren't there and aren't important.

I could've sworn in a court of law that textev witnessed the RMN finding out that Apollo's ECM were also effective against enemy missiles. Implying that it had not been previously used in that capacity. Am I misremembering something?


BTW, if the MAN adopts a CM-ship defense, it should be very effective with their "nextgen" C-phract CMs.

I think the timing.

This was observed, but much earlier than Apollo. At the very least, Apollo has little to do with ECM anyway. Any improved ECM effectiveness due to the control missile would also be irrelevant in the condition you're talking about. Firing Dazzlers close to the launching ships isn't typically done, but was in the books somewhere to confuse the attacking missiles.

Jamming incoming salvos using Dazzlers is definitely something the RMN did. But I can't find any reference to it until after Apollo was a thing; though nothing about it appears to require Apollo as the Mk23 Dazzlers would be effectively identical between Apollo and non-Apollo pods.

It's mentioned a couple of times in AAC
At All Costs wrote:Brankovski had five hundred and sixty LACs, one for every thirty attack missiles, and they punched a steady stream of counter-missiles into their teeth. Tethered and free-flying Ghost Rider decoys sang to the Republican MDMs' sensors. Dazzlers were launched into their faces, exploding in bursts of blinding interference. And Imperator and her consorts punched out wave after wave of Mark 31s.
The front of the Republic's missile attack eroded under TF 82's defensive fire like a cliff, crumbling under the assault of a stormy sea. But, like the cliff, it was only the front of a far larger mass. Thousands of MDMs were killed, yet more thousands remained, and Honor Harrington watched them reaching out for her command.

At All Costs wrote:The LACs couldn't place themselves between one threat and the rest of Third Fleet without leaving it uncovered against the other, and so they held their position, spitting Vipers against the wall of destruction crashing towards Theodosia Kuzak's command.
Thousands of Mark 31 counter-missiles went out with the Vipers, and Truman felt Chimera quiver as her own counter-missile tubes went to rapid fire, but nothing was going to stop all of that torrent of MDMs. Decoys and Dazzlers strove to bewilder or blind the incoming missiles, but still they came on.
Note that (except for McKeon's handful of ships, attached from 8th fleet) none of the 3rd fleet ships had Apollo -- proof that using dazzlers defensively doesn't require Apollo.

Then it's mentioned briefly again in UH
Uncompromising Honor wrote:The Dazzlers had been originally devised as a penetration aid, designed to knock down and blind the sensors feeding a target’s defensive fire control with massive spikes of electromagnetic and gravitic interference. They were especially effective against counter-missiles [...]
That was what the Dazzler had been designed to do, but as the Fleet’s missile officers played around with it, they’d quickly realized it had another function. After all, attack missiles and the ships controlling them relied on their onboard sensors, too.
[...]
“What the hell is that?” she demanded.
“Some kind of jamming,” Rosiak replied. “I don’t know how they’re doing it, though. We can’t see shi— That is, we can’t see very much through all the garbage, but CIC’s computers say it’s coming from at least a couple of dozen sources. That means it has to be some kind of independent platform. I don’t see how they could sustain emissions at this intensity for very long without burning out any emitter you could put into a drone, though, and—”
He paused again, pressing the fingers of his right hand against the earbug in his right ear and listening intently. His lips tightened, and he looked back at Isotalo.
“CIC doesn’t think they are sustaining emissions for more than ten to fifteen seconds per platform, Ma’am. But there are a lot of them, and they’re running them in a cascade pattern. That’s going to play hell with the attack birds’ seekers.”

Uncompromising Honor wrote:He hit a macro on his console and the missile control which had passed to him launched Dazzlers from every tube the task group had. They didn’t travel far, and then they erupted squarely in the path of the incoming Cataphracts. There weren’t enough of them and the shell wasn’t dense enough to block all of the Solly missiles’ sensors, but it was close enough to the task group and broad enough to block the vast majority of them, and Solarian missiles didn’t talk to each other the way Apollo birds did.

To End if Fire also mentions the tactic.


By that late in the series RFC had mostly stopped explicitly reiterating the onboard ECM and jammers of the ships -- which might be why Penny appeared to have forgotten they had those. (Though AAC at least mentioned their decoys)
ECM and Jammer as an anti-missile tactic wasn't new; but dazzlers provided an additional approach to it; and one that could be activated further from the ships and closer to the attack missiles. (And by jamming from relatively distant remote platforms it makes any "home on jam" capabilities of the missiles basically irrelevant)



What they don't seem to have attempted is using Dazzlers at really extended ranges to jam the control links to the missiles and force them to go autonomous way earlier than normal. (By the various descriptions it seems like dazzlers weren't going off until lightspeed lag already cut the missiles off from new updates from the launching ships, and so they were focused on more jamming of the missile sensors. Whereas, if launched the dazzlers earlier you could potentially set them off as they passed the inbound salvo halfway between the ships and deny many of them control updates for critical portions of their flight. (This would work especially well when using Apollo for offense because while that jamming would likely also mess up your own long distance lightspeed control links it wouldn't bother the FTL links to the Mk23Es at all)

Something that would be interesting to see is fitting dazzlers/EW/whatever into *countermissiles*. I wonder if it would be effective....

dazzled; dazzling ˈdaz-liŋ ˈda-zə-liŋ
Synonyms of dazzle
intransitive verb

1
: to lose clear vision especially from looking at bright light
2
a
: to shine brilliantly
… the woods dazzled whitely …
—Truman Capote
b
: to arouse admiration by an impressive display
She dazzles in her live concerts.
transitive verb

1
: to overpower with light
was dazzled by the camera flash
2
: to impress deeply, overpower, or confound with brilliance
dazzled us with her wit


In other words: ECM JAMMING, as has been described since the very FIRST book of the series.

Spoofing has also been around since the FIRST book of the series. I will note that "ghost rider" missile spoofing made a VERY brief appearance and magically disappeared. DW clearly though it was WAAAYYYY too powerful. As it made 5000 missiles RHN missiles do absolutely nothing against a mere handful of ships. So SLN or MALIGN would require tens of thousands of missiles to try and accomplish the same thing. AKA To End in Fire could NEVER have happened against an entire fleet(personally, I just add a zero or two to total missiles fired by Galton to make said damage if you wish to make series consistent). Uncompromising Honor could never have happened at Hypatia(well it probably still would have). RMN ships would in effect be invulnerable making boring stories and it was effectively written out of the series.

That is what I remember. I didn't think it was as close back in the series as UH. But yeah, the RMN realized other benefits of the Dazzlers.

And I thought the Dazzlers and the Dragon's Teeth were developed alongside and introduced with the Apollo system. That's how I remember it anyway.

Nope, they significantly predate it. They're first named in Ashes of Victory, which means they pre-date microfusion powered missiles. At that point, prior to the end of the first war the RMN was still using capacitor powered Mk41 MDMs.

Then during the ceasefire the RMN developed the microfusion powered Mk23s (and Mk16 DDM, which got its own version of those). But it was only after the start of the second war (so something like 7 years after the first mention of Dragon's Teeth and Dazzlers) that Apollo entered service.
