Hearthguard - 2,500,000 Ton Clan Warship

[Karack Blackstone]

Hearthguard

Ship of the Line, on the drawing board.

I can go back in and redesign if anti-small craft firepower is needed.

More a proof of concept ship than anything. Still, lots of Cap Heavy Naval PPC guns, that's for damn sure!

Thoughts please?

[Liam's Ghost]

Two considerations at first glance:

1) ATAC is intended to work with unmanned drone units like CASPARs or drone aerofighters, so you're not really going to get any use out of it.

2) The Laser AMS is waaaaay too overblown. Anything beyond twelve AMS per arc is arguably pointless, since that's sufficient to take out a killer whale or its nuclear derivative, and AMS bays engage every missile that enters their firing arc automatically as long as you have either ammunition or heat sinks to keep firing them. Which leads to another reason to scale back. You have a bit less than twenty three thousand heat dissipation and your AMS bays eat up a thousand of it with each volley, meaning you'd only be able to engage twenty two naval missiles a round, assuming you fired absolutely nothing else. It's a small enough margin that you could be overwhelmed with missile attacks, or alternately locked out of firing back for fear of an errant nuke getting through. As a third reason for cutting back, AMS don't require gunners, but they do require fire control tonnage. All those AMS make everything else heavier. You can actually see signs of that in your design, which is fairly lightly armed for a ship that big. That's fire control tonnage sucking away your potential warload. 

Also, you can only legally mount one lithium fusion battery.

Against fighters, sufficient naval PPCs are sufficient, since they can use bracket firing.

[Karack Blackstone]

Tried some changes.

Thank you for the tips.

Heatsinks should be more. I have like 27,260 Clan Doubles in the thing in the Lab, but it for some reason truncates that number to the 11,200 in the export.

this is the kind of critiq that I am needing for my own designs in my Nroe fleet thread. thanks for the info but I do have a question about your second point. yes 12 ams can destroy a killer whale missile and its nuke version but what if they launch hundreds of missiles in the salvo and only one killer whale or its nuke version how many missiles would be taken out then

Under current rules, the AMS bay engages every capital missile individually, with the only limit to how many it can engage in one round being its ammo capacity or heat sinks.

So, assuming you have the ammo or heat sinks, all of them, even if they're all launched or reach the target in the same round and pass through the same facing where only one bay can engage.

[Karack Blackstone]

Made one hopefully last revision.

Seems decent enough.

[Andras]

The SI is way too low. You have 272kt of cargo, put half of that into SI and armor if that's what it takes, but only around 600pts of armor can get blown out by a cruiser in one go. You need at least 1000pts of armor on every side with that big of a ship.

Armor should be close to even on all faces, you can't count on keeping your nose pointed on, and you are losing out on most of your firepower if you do that.

I added 120 extra DHS for 20 additional AMS volleys above the 100% Heat sink coverage I already had.
5x4 HNPPC bays per corner arc and a 66pt Naval Laser bay on the F/B/A arcs brings as much firepower as yours does in the front/aft overlapping arcs and almost (11/12ths) as much on the overlapping broadsides.

One of my Barracuda missile volleys will wipe out enough of your heat sink coverage to shut down a HNPPC bay, and by firing around the corner I can bring two of them on you IIRC.

[Karack Blackstone]

OP updated.

[Karack Blackstone]

I have one final pass of fixes.

I need to provide some 2nd Class Quarters for the 30 Aerojockies and 150 BA Marines / Elementals.

Other than that, done.

Is this thing ready to be declared done, after all?

[Andras]

Max out your doors. You should have the maximum of 33 doors to launch your fighters as fast as possible. Once I figure out how many doors I can have for fighters, I usually have 3x as many fighters.

With 33 possible doors, I'd probably have something like this
24 doors for 72 fighters.
6-8 doors for 12-16 SmCraft
1-3 doors for cargo bays.

[Lagrange]

I usually make #fighters be a factor of 2 times than the number of doors for them, since you can launch 2/turn.

Also, I think doors need not be specifically dedicated to smallcraft independently of fighters.

[Karack Blackstone]

Current plan when I get the time to make the changes is thus:

30 Fighter doors, 3 sets of 10, 90 total fighters.

2 Small Craft doors, unknown number of SC's.

1 Cargo door, spare tonnage. Not clear on how much that will be yet.

[Karack Blackstone]

OP updated.

[Karack Blackstone]

Done-ish?

Worth it?

Seems decent enough.

[Karack Blackstone]

Should be final change.

[Karack Blackstone]

Andras, one final question.

Do you think my ship would stand a chance against yours in a fight?

Why?

If willing to reply, thanks. If not, you're fine.

[Andras]

Andras, one final question.

Why?

If willing to reply, thanks. If not, you're fine.

Well, now that you tripled the fighters and doubled the armor, yeah.

[Karack Blackstone]

Thank you!

I thought it would help. The Cargo tonnage seems a bit light now, but, meh.

[Karack Blackstone]

Hello.

I'm going to see if I can modify the number of DHS's as I have so many to free up enough weight for additional armor.

I intend to get at least 1,400 per facing, or at least, try.

[Karack Blackstone]

Armor as is, which is maxed out.

Armor tonnage was wrong, fixed.

[Tyler Jorgensson]

I like it, but not being an player of the Aerospace side of BT I can’t comment on how good it is.

[Karack Blackstone]

Thank you, Tyler!

I don't really know either, but it can fire all of its Laser AMS batteries 22 times in total before having to finally worry about heat tracking and limitations!

[Tyler Jorgensson]

I mean 100 odd Heavy Naval PPC’s is gonna leave a dent. Six Droppers is enough to carry a decent mix of supply, assault, or carriers without raising the cost too high. 90 fighters is a good air group: three full Trinaries of fighters and a handful of small craft for miscellaneous operations. I think the armor is good as is the SI, but DHS seems high to me. From what I could see the weapons only generate 30,000 of heat. The cargo is fine for such a large vessel: I’d assign it a Cargo Warship like a Carrack to shadow it. Good AA array in the lasers, but could probably use a couple more weapons IMO maybe some pulses? Also needs a portable HPG because as a Fleet Flagship is should have that capability: could probably use Naval C3? Also I need to look into how fuel is used: to me that number seems low but I know nothing on it lol

My two cents now that I’m out of work: again take with a grain of salt.

[Lagrange]

Here are some optimization suggestions if you are interested.

(1) Convert 12x LAMS batteries into 4x LAMS + 8x AMS with some deep ammo reserves for AMS.  Drop some of your excess HS to make up for the ammo reserve.  LAMS is fine for dealing with small amounts of routine missile attacks, but you can deal with a much larger coordinated missile attack using AMS. 
(2) Drop AMS batteries from fore/aft right/left side arcs.  The broadside (L)AMS batteries cover the same hexes.  Dropping the redundant ones will help frees up lots of tonnage because you are beyond the 20 weapons/arc limit.  With this change, you'll only have 4 arcs with (L)AMS. 
(3) Shift all the broadside naval weapons into the Fore/Aft Right/Left side arcs.  The overlap of fore/aft arcs is almost the same as the broadside arc so there is little drawback, and the shift will help with fire control.  Furthermore, you get strong side arcs.
(4) Shift all the ERLLs in Fore/Aft Right/Left side arcs into the broadside.  This drops the weapon count in the the side arcs below 20 which means you have no fire control tonnage.  Note that the broadside arc can be used to cover many more directions than you might otherwise expect via an ECHO operation.
(5) Add 30 more ASF.   All these additional ASF can be launched in round 2 because you can launch 2 ASF/door.
(6) Consider swapping a few HNPPCs into several NL-55s.  NL-55s can be used in anti-ASF mode with only a modest penalty to very long ranges.  Furthermore, they do AE damage which means any ASF with reflective armor take double damage.
(7) If using individual ranges, consider swapping one HNPPC for a Light Naval Gauss bay.  They have just a bit more range so this prevents a faster warship from playing tag.
(8 ) Consider adding capital missiles into the broadside arcs.  Capital missiles are great at destroying stationary targets.  They can be fired from across a stellar system at a space station (for example).  Furthermore, multiple flights can be stacked so they all arrive at the same time via careful use of thrust between launches.  On the other hand, dropships can fulfill this role fine.

I know it may sound strange, but I personally use Hull Defense vehicles all the time...

Have you considered such a tactic? Maybe a Binary of heavier ones for mobile defense, particularly when you lose a non-capital bay...

I'm struggling to consider ways to keep the firepower yet gain the advantage of using the NL 55's.

Yes it saves overall on tonnage, but the problem is, the Capital Weapons firepower seems to go lackluster to me.

I'm going to work on this a bit.

[Lagrange]

Yeah, capital weapon damage/ton is an order of magnitude lower than other weapons. 

Incidentally, as long as you have a few NL55s to handle particularly long range fire against ASF, swapping the ERLLs for LPLs seems desirable.  Extreme range is pretty poor for hits, and the LPL's -2 to hit bonus tends to be pretty good.

[Karack Blackstone]

I'm trying to figure that out.

Going to NL 55's over a full battery of HNPPC's (4) requires 12 to get to 60 Cap Dmg, 55 damage needing 11 NL 55's.

At 3000 Tons for a single HNPPC, and 1386 for a NL 55, it's not really a great "upgrade" when my firepower nosedives.

I may change the ERLL's to LPL's, which will about even out thanks to DHS needs going down as well as the tonnage up since the +2 Tons per weapon will occur.

Dang, this thing hits hard, but optimizing it surely isn't easy!

[Lagrange]

Yeah, it seems like you are more slot-constrained than I realized.   

Instead of relying on NL-55s for small things at large ranges, you could use the HNPPCs in bracketing fire mode.  They annihilate an ASF on hit (24 capital damage), with a to-hit penalty against ASF of only +2 (+range).   That's less damage/ton vs ASF than an NL-55 array can put out, but the to-hit is 1 better and it doesn't cost extra slots.

Check out this thread which has an analysis of the chance to hit fighters with various capital weapons. https://bg.battletech.com/forums/index.php?topic=52524.0

For most capital weapons, the chance is not very good. I'm certainly reconsidering some of my weapon choices since I read it.
