So, you want to make a Viper CM Mk2 Dual head version, where its single laser rod takes out clumped missiles. Tonnage ~ 20-->30t for the missile. You can fire 2-->3 normal CM's for identical tonnage.

Percentage of interception @range * number of possible shots.

So, obvious math shows this will NEVER work at long range as percentage at long range stinks. So, this Viper CM Mk2 dual mode has to potentially take out 2 per shot to equal normal CM's at close in range.

Apollo is 9 supposedly "clumped" missiles. Uh, not exactly, they will still be in a ~50km x 50km square or thereabouts.

Viper current missile we do not know what range they can attack from and actually HIT anything. 1000km? 10,000km used to be "long range" and this is a single DD class laser rod after all. It hit with what diameter from said distance? No one knows, nor will anyone.

Of course in opposition:

This is a DD Grade single shot Viper CMSo, you want to put a PDLC on a missile(effectively), but if this is possible, who in their right mind would not do this from a ship with VASTLY more POWER????? Buehler....? Buehler...? After all the missiles are FAR more clumped up while attacking than while maneuvering in space. Are you telling me Engineers/designers in HV are so DUMB, they cannot do this on a ship, with VASTLY more available tonnage and power and vastly superior sensors??? Really?

Of course a Katana has 3 ?14 element 200,000km range PDLC which is ~equivalent tonnage as BC Grade Graser. So roughly ?4000t for 3 PDLC, SD grade = 1300t each + power supply required obtains single shot per missiles, at 200,000 range. You don't suppose HV Engineers would have thought about a wider beam dual mode PDLC for close in work eh? I mean common!

There is no way a PDLC actually predicts a missiles path, aims, fires a NARROW beam creating contact. There is a guarantee that PDLC's are already a WIDE dispersal beam. ALREADY doing it.

Exactly! Just responding to your post upstream when I said all targets with wedges are easier to kill with shots down the throat. I'm making sure we're on the same page as your reply doesn't apply to missiles.

It is difficult to get a shot down the throat of a warship. But if you do... bye-bye.

I did not say that there were bow walls or bucklers for missiles; what I did say was that a shot down the throat did not guarantee a hit (the cross-section is much smaller than the throat size) and a hit did not guarantee a kill. So it is NOT automatically "bye-bye".

The ship killer missiles have multiple beams aimed toward the ship and even that does not guarantee significant damage. Hence the shot that does might well be the golden BB.

However your current plan might have only one beam per missile, so your chances of a kill are much less.

Right, I was responding to "all targets" which is vastly broader than just missiles. So I was pointing out certain targets that weren't necessarily easier to kill down the throat. And having a bow wall is one way the be at least as tough to kill using a down the throat shot.

Of course if we want to be really technically missiles are also an exception. :D Sure, they don't have any protections from a down the throat shot. But since they also don't have any protection from a broadside (or up the kilt) shot they are equally easy to kill from those angles. And since they're equally easy to kill from all those angle then they can't be easier to kill from down the throat ;)
They're only protected by their wedge, which only blocks fire from some angle above or below the plane of their heading



Also, while it's certainly worse for warships (assuming they don't have a bow wall up) to get shot down the throat it's not a guaranteed insta-hill. That's why their hammerheads carry physical armor - to reduce [well, destroyers hammerheads might not; but cruisers and up will be armored hammerheads]. It's not as good as a sidewall; but it's better protection than, say, a merchant ship would have. So they can usually survive multiple hits down the throat (just fewer than they can survive from the broadside).

Closer to an actual Golden BB would be a down the throat shot on a warship than came in from high (or low) enough it managed to bypass the hammerhead and strike the dorsal or ventral side of the main hull. There's lots of important external things there (sensors, radiators, antenna, boat bays, etc.) plus those parts of the hull are the least armored (often unarmored even up to BC size) because they're normally protected by the wedge. But even such a grazing shot isn't guaranteed to kill or cripple the ship.

Thanks for your input Relax! Your posts are appreciated and respected.

Well the death blossom idea was conceived to take out at least dozens of CMs with a single CM. If the tactic is not going to threaten that kind of efficacy then what's the point. The notion is, or was, originally suited for a missile technology featuring several seconds of fire. So, an iteration of their technology that I think the MAN might throw at the GA’s horrendously huge salvos. I'm also suggesting that the MAN may have already developed a g-head that fires for only a second or so, in a much smaller missile, with lower output that would be suited for this application.

See above. I think the MAN is going to develop a wholly new tactic to deal with the huge GA salvos. I learned from the series that a lot of solutions are born out of future iterations of existing technologies. Havenite navies chastised themselves for not seeing certain iterations coming. Paraphrasing… “We should have known they'd get around to including a laserhead on their stealthy probes,” as one example. A 3-second firing missile technology must have a lot of different applications available to it. I seem to think this might be one of those applications, but then, you know how arrogant I can be. I'm an Alpha too! :D

I dunno how or what form it would eventually have to take on to be feasible. Those are the kinds of things partly worked out in the field.

No, I'm not saying HV engineers are dumb. More like suffering from “made in the GA” mentality? SLN-like indoctrination? White Haven-itis? Necessity is the mother of invention? Besides, the GA is not a conglomerate made up of Alphas. And Alphas will turn a problem on its head.

Reminds me of the US continuing to rely on aircraft carriers and China and Russia threatening area denial to aircraft carriers with the rail gun. And the tactic of making the US shoot down $2,000 drones with $2M missiles.

Not to mention the relatively cheap $100M Swedish sub that sunk the 6.2B Ronald Reagan in a wargame. :o

In a word, complacency.

Anyway, why didn't the GA think of spider-drive ships? Grasers that fire for seconds instead of 5000 microseconds? Mating a CM to a missile? Etc. Are they dumb? No. Just coming from a different mindset.

But I'd like to hover over this thought for a second…

Relax wrote:After all, the missiles are FAR more clumped up while attacking than while maneuvering in space.


Believe it or not, my original death blossom idea was initially meant for missiles that are attacking. Or whatever range is optimal for the application. As you say, that's when they are clumped up. But everybody ran with what they thought I was trying to say in the post that I just went with it. It was interesting and it still applies. I didn't consider those angles.

Anyway, the MAN needs a very efficient CM tactic to counteract the huge GA launches. I still think that if they can develop a CM hat has a firing time measured in seconds, even one second, detonating in the midst of a huge flock of birds can potentially take out many birds with one shot.

I'd like to pause at this point to field another notion. First, I’d like to thank everyone again who posted their idea of a “Wall of Battle.” I'm not the type to shy away from asking these type of questions in class out of embarrassment. I found out long ago that there are other people in class with the same question who are afraid to ask. And in that case it turned out that everyone had a different view of what a Wall of Battle actually looked like.

Having said that, textev has thrown at us a “wall of missiles.” I may be seeing that wall of missiles differently than all of you. I don't see those missiles spread out in a single line like a wall of missiles would normally infer. I simply cannot believe that salvos sporting thousands of missiles will have a chance of attacking a ship if they are all spread out in a line. The line would be so long that the missiles on the ends or so of the line would be out of position to actually attack the ship. For example, let's consider the defensive line on the football field. The defensive end is so spread out that he rarely gets in on the tackle unless the play comes his way. Attacking warships at a warship’s acceleration with a line of missiles spread out horizontally just won't allow all of the missiles to get a shot at the ship. It'll be like being in the wrong lane on the Interstate and missing your exit. It's too late to maneuver for a shot at that exit.

Having said all of that, I envision a wall of missiles having lots of missiles behind it as well. In that configuration a death blossom mode should be able to shoot down the throat of a missile and many of the other missiles trailing it.

The notion of the death blossom precludes having to aim. One does not generally do too much aiming when firing a scatter gun into a flock of birds. I'm thinking that control links shouldn't matter much either.

I still think you're dramatically overestimating how tightly packed missiles have to be even when they're on terminal approach.

'Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is :D

RMN missiles have a 50,000 km standoff range!
Even with the somewhat restricted angles they have line of sight on the ship from (thanks to the wedge), even when it's broadside on, that sheer distance makes for a vast area they could engage from.


Let's say, arbitrarily, that they can attack from an 80 degree firing arc against its broadside; so up to 40 degrees either way off perpendicular (to keep form getting too close to the PDLCs of the next ships in the wall of battle).

Given the length of the SD (~1.3 km) and simple geometry that means they can fire from anywhere along a horizontal line 64280 km long. (Technically a shallow arc; but I'm simplifying)

From the point furthest aft of the ship on that line the height between the wedge planes is 51.7 km tall, and the point furthest forward of the ship on the line the height between the wedge planes is 178.2 km tall.
Because of that, the area from which a laserhead can hit the ship (from within that 80 degree horizontal arc) is effectively a sideways trapezoid (50,000 km out from the ship) with bases of 26,427 km & 91,034 km and a length of 64,280 km: an area of about 3.7 billion km^2

So there's tons of room room for missiles to spread out horizontally and vertically and still all be able to hit the same ship. (In theory, room for over a billion missiles, with wedges up, to simultaneously squeeze into that area)

(Things get more crowded if you've got missile trying to target adjacent ships in the wall; as those are only ~500 km apart and so their trapezoidal attack zones significantly overlap. But even so, with each missile + wedge only taking up a couple square km of frontage, there's lots of room for the salvo to attack without stacking missiles 'in train' behind each other)

Based on the previous post by Jonathan_S, you are not shooting into a flock of missiles with a scattergun. Without aiming, you cannot get close to a missile without aiming.

Missiles are not spread in a line. If they were then a single CM could take out more than one missile. <Debris>

Lets assume they are in a phalanx line perfectly aligned perpendicular to line of motion. CM(LC)runs out there, drops its wedge turns 90 degrees and waits for them to come abreast of CMLC like a Rugby match. Right?

KABOOM! Several missiles KABOOM! WOO HOO! In fact you fired a WHOLE bunch of CMLC and WIPED out an alpha strike! Bravo! Well, great, what is solution to this tactic? Offensive missiles wedges offset rotationally a bit to each other so all their broadsides do not line up like ducks in a row. In fact, no 2 missiles broadsides would line up.

So, even assuming CMLC could work, it would work only once.

I originally thought you were trying to Defend down their MDM throat which mathematically is beyond hopeless scenario even when one assumes they are going to Apollo style control missiles. Even lightspeed Apollo has god like qualities at extended ranges so... seems obvious everyone will go this route, though why they could not share computational duties is a head scratcher. Redundancy alone would necessitate this basic reality.

Ah well, kid is sick and so am I so, on flu duty tonight.

Sure. I understand. I was just putting forth what the original goals were of death blossom. If it won't work, then let's scrap it.
