Oh well guys thanks for the welcome! I said i was new to this forum, but im not new to forums! Meaning that i welcome forthcoming exchange of ideas but im familiar to forum feuds and fights centered in looking for arguments to dismiss the other ideas. I´m not interested in that at all (been there etc) so ill try to focus in what you think of the case im presenting you and in the case theres some confusion ill try to clear it.
The problem with that is that missiles can (and DO) maneuver, while autocannon shells cannot. They are purely ballistic Something like that MIGHT work the first time (personally, I doubt it), but as we saw with the Triple Ripple, it will be countered easily enough after the first use or two of it.
Frankly, the only time during a missile attack that autocannon would be useful is in the last few seconds before the nuke in the missiles lit off to activate the laserheads. That is the point where a missile's path is easily predictable, since it needs to settle down to release the laserheads. However, by that point, it's a bit too late to be firing autocannon.
Yes, missiles do maneuver you are right. But missiles
HAVE to be launched in a vector, because they have to
achieve an intercept to their target. What limits their maneuverability considerable herding them into a path.
Moreover, what we are seeing in the Honorverse is incredible amounts of missiles being fired coordinately. On a vector which needs to produce an intercept. Those missiles
occupy a volume in space, and the beauty of using autocannon rounds that explode in shrapnell is that it would use
exactly the same principle a counter missile uses. Predict the area in which the missiles are going to be, and instead of locking into them occupy the space with shrapnell. Since they´re ballistic, they don´t depend of fuel and can be fired as soon as a vector appears clear enough to have a chance of some success.
If we were talknig about conventional autocannon rounds,
yes, they are useless but for the closest ranges since they need a direct hit.
The way I see it as well, is that if autocannon could be that effective, then why aren't the RMN, RHN, GSN, or any other "modern" navy still using them? The only reason the sollies still use them is because they just haven't gotten around to updating the ships that are a couple hundred years old. The fact that even the sollies are trying to upgrade them also tells me that as behind the times as they are, even THEY understand that autocannon aren't really worth keeping around.
As they were being employed, exactly. At least my understanding is that autocannon was a ship to ship weapong employed too in anti missile defence in the closest range. As such, the changes in weaponry have
effectively made them obsolete as they were being employed (maybe they would be of some use against LACs but the Solies never had the chance to try).
In any case
that´s not the use im proposing.
Edit to add: Shrapnel doesn't really give ANY advantage, as missiles are shielded above and below with wedges. Now, I suppose you could make an argument for directional shrapnel, such as that used in a Sidewinder missile, but again, there's a very narrow window through which it needs to go, and even the minutest jog on the part of the missile will generate a miss. Basically, what you're proposing is the "throw a bunch of ball bearings into the path of the missiles" idea of anti-missile warfare. Doesn't work that way. Space is huge, and you'd need a shit-ton of ball bearings/shrapnel to even get a single hit, let alone a way of taking out many missiles.
You are
correct. But i would specify a little bit. Throw of
exploding ball bearings into the path of missiles. Space is huge yes, but as stated incoming missiles need an intercept vector. After all, is what countermissiles do. Now if each of the balls explode in 1000 metallic fragments in a 360º sohere, adding to their inertia the explosion acceleration, i think we can agree you can occupy a
sizable portion of the path of said missiles. Many of those fragments would be wasted into the sidewalls yes, but not all, since there would be incoming fragments from different rounds in 360º. And missiles are not armored, one impact would be enough, at those speeds, in all likehood, to produce a miss.That
would be an efficiency win by far for the ball bearing.
There is also the minor detail that auto-cannon rounds don't self-destruct if they miss. That means that auto-cannon spread "hazards to navigation" throughout the volume of a battle with no way to clean things up.
Well yes, as i don´t know how many fragments of all fought battles in the honorverse are. Because i don´t think they recover every bit of blasted LAC or SD, and believe me they´re still moving unless something stopped them.
But they would clear up, same as other debris, because they would still move, and sooner or later they would either find something that stops them or leave the system. Same as any other debris.
I think you're selling the innovations short. Off the top of my head the anti-missile anti-LAC tech improvements (not just tactical doctrine) since Buttercup unleashed them are:
1) GSN Katana space superiority LAC (which you mentioned)
2) RMN Mk30 130,000gees CMs (Battle of Sidemore) improved enagement range against missiles
3) RMN Mk31 130,00o gees for an extra 15 seconds CMs even more improved engagent range (3+ million km vs ~1.5 million km with older CMs)
4) Keyhole - allowing vastly increased numbers of CM salvos (11 or so vs 3-4) (Oh and from both broadsides at once, doubling the anti-missile density per salvo)
5) The Viper anti-LAC missile (used by the aforementioned Katana)
6) Adapting CM launchers of modern units from DDs - SD(P)s to also fire the Viper giving them a devistating anti-LAC capability
6) Probably should throw in Bow/Stern walls making it even harder for missiles to get a clean shot at the ships
7) Improved free flying decoys (Lorelie)
8) RHN Triple-Ripple missiles (yes a tactical invocation, but one enabled by the specially designed missile warheads)
9) RHN LACs - designed primarily to blunt the offensive use of RMN/GSN LACs.
It is a good point, and i think
i didn´t elaborate on it more before. I don´t mean that nothing has been done, and as you say i mentioned the Katana making an example of it. What i meant is not that theres been no attempts to address them, as you are proving. But they´re all based on the same vehicles so to speak: improvements related to known combat systems like the LACs or Vipers or the enhanced CM launch. LACs, missiles, sensors.
Theres no effort to find a new combat system that would modify the existing status quo. That´s what i meant by going back to the drawing board. The RMN did it when it developed the SD(P) and the LAC Carriers. They were new combat systems that
wholly modified the status quo.
So I don't see where the GA has a need for desperate stop-gap measures to fend off missile swarms or LAC strikes. (Leaving aside that the SLN doesn't appear to have any way to use LACs offensively - nor are they likely to have LACs capable of threatening even old-style units except in vast numbers).
So the need for an AA escort seems lacking - at least for the good guys. Now maybe the League will try such a bodge - I'd bet against it working but I could see them desperate enough to try...
You´re are
absolutely on point regarding that they don´t need desperate stop-gap measures. Their superiority as it is is massive enough.
But i didn´t mean it like a desperate move. I meant it like a
meaningfull way in which they can deploy ships that are going to be an assest
in a time in which they have NO CAPABILITY to deploy any other. Which means that if the idea has merit at all and achievable, the SDs are not a waste.
Furthermore, i also agree with you. Is the SLN the first one that should look into a way to change the status quo. But i don´t think its realistic to expect it, at least after the very efficient way in which David has described how utterly incompetent and bureacratic the SLN is. They have also adopted the strategy of raiding which lends them away from fleet to fleet tactical thinking. At this point im afraid that if a SLN flag officer appears try to do something constructive is going to feel not realistic at all.
One point not mentioned yet is why the autocannon was dropped from gthe offensive arsenal to begib with - stand off range. Lasers, with much lower cycle rates got out to further distances, faster than a bullet.
And with the advent of the laserhead, the auto cannon has no chance. Laser head stand off ranges are 30 to 50 thousand kilometers now. That is 3-4 planetary diameters at their closest approach. You just cannot get enough lead far enough out in time to stop them. And this is only self defense, not even the distances needed for mutual defense
The obvious counter to this argument is saturating the Space around the ship with shots (sandcasting) however, given that the average honorverse ship accelerates at over 300Gs, any cloud generated will quickly fall behind the ship, and any cloud of slugs dense enough to guarantee interception will block sensors and weapons.
The reason autocannon is not used anymore is
well stated in your own reply. As ship to ship weapon, is
utterly inferior to lasers. A ship doesn´t need to produce an intercept vector so to hit anything at long range with autocannon when the target can maneuver or roll is... well... utopical. I would keep a couple mind you for ground bombardment or orbitals destruction xDDD but as they were being used they´re obsolete.
But i need to point out that i am not proposing sandcasting (which has appeared in other works). Sandcasting would need to be close to the ship, and even if it keeps the inertia (not falling behind) it would require the defending ship to not alter acceleration so it doesnt get ahead or fall behind of its sand cloud. Im proposing honest to god FLAK fire, that can be send yes, to extreme ranges because once the missiles are committed to a vector they occupy a volume of space that you can try to occupy too with your own counterfire, and that path can be predicted in pretty much the same way a CM needs to predict it. And ball bearings do not need drives.
Maybe the most glaring point absent is what has been pointed out in other replys. "Possible but why bother?" Why, indeed, employ that effort to use what are clearly obsolete vessels?
Under normal circumstances, i agree with most of you: there is no point. The GA doesn´t need them and its techonologically way ahead of what those ships represent. What is worse, they´re building SD(P)s and we are talking about normal SDs that CAN´T be retrofitted into podnaughts.
So why do i come with this idea? Or better said why think in way in which those blasted Solie SDs would have an use?
Firstly, because in the present circumstances of the SEM i think that
any way in which they can increase their numbers in a meaningfull way for the next year or two is an
absolute need. All meaningfull shipyards are destroyed so no new units until the new shipyards are finished AND the then started ships get completed. That´s an
awfull lot of time for a navy as stretched as the Star Empires.
Secondly, because as you can see usually in RFC works,
the military race never stops. If you want to stay ahead of the game, you have to come up with the ideas and implement them yourself, otherwise is your enemies the ones that are going to use them against you and you won´t be able to counter it. An excellent historical example of how a weaker enemy seeks a way to challenge the status quo is the employement of armored units and doctrine by Germany in WWII... something that had been theorized by the british and the french and discarded because they didnt need them. Or Japan´s use of aircraft carriers.
Ideally the RMN would design a new paradigm ship from scratch, yes. But now they just can´t build it. This way they get something from those SDs, if achievable at all.
Thanks all sorry again for the lenght
