I believe secondary duotronic core wasn't even strictly necessary for the design, more of a half-joking "break glass in case your isolinear computer is trying to overtake the ship and just behaves crazy in general", or other such situations. If it's possible to not remove them, I would like it - it is an excellent plot hook.
 
Having written that story after I found out about the secondary duotronic core... I'd be happier keeping it, but if someone asks me "are you enough happier to justify sacrificing an extra +1S or +1P to the ship," I'm going to have to sweat about that.
 
And these are the reasons it's removed! To give Eddie Leslie sleepless nights worrying about crazy supercomputers taking over the Federations most powerful ships... Muahahahaaa!

Ahem.

Over to Lt Galan:​

"From the design point of view, the 2270s secondary core is so outdated that the increase in performance from swapping the core from Duotronic to Isolinear beat its contribution by an order of magnitude. The old core is, unfortunately, a statistical rounding error- one that requires four and a half full time crew and about 1.5% of reactor output to maintain. The processing power isn't sufficient to save one single refit part- for example, we replace the four T2H SR sensors with two T4H SR- with higher performance but heavier weight per part. It would be cheaper to refit if they could stay as two T2H SR sensors, with the difference made up elsewhere. The secondary core isn't even close to bridging that performance gap.

Margins on this design are so finely-tuned that Personnel would have pushed the Ambassador into a higher crewing category of both Enlisted and Technicians and into higher build and refit resource cost categories."


(I.e. it become O7E8T7) and again, boundaries, the extra power required pushes it to an extra +10BR/+10SR new build cost and +10SR refit.

And... the stories that can result from not having the backup anymore are also interesting. I knew this would be A Big Thing when I called it out.

I do think there are some designs that keep the core. The only way this design can offer 68 stats for 776 crew and 320/260 and 120/110 refit is to remove it and use the space better. I like to think the additional power conduits for a future Holodeck are diverted from the removed secondary core to the new Rec centre.

Honestly he's more worried about crazy supercomputers pulling dumbass moves like blindly ramming the ships into black holes and things. :p

In Leslie's experience, berserk computers taking over the ship are less of a problem than dumbass computers accidentallying the ship.
 
After-meeting Q&A - Alliterate
After-meeting Q&A
Part 1

After the presentation when things have broken into smaller conversations, Lieutenant Galan is fielding a questions from a Vice Admiral and a Councillor, who asks-

"Why remove the Constitution cores? They're old old tech but they work first time every time. The Enterprise even has Kirk's Enterprise's Duotronic Core, I'll be sad to see it go even if it probably belongs in a museum."

"That is a good question, Sir. From the design point of view, the 2270s secondary core is so outdated that the increase in performance from swapping the core from Duotronic to Isolinear beat its contribution by an order of magnitude. The old core is, unfortunately, a statistical rounding error- one that requires four and a half full time crew and about 1.5% of reactor output to maintain.

Margins on this design are so finely-tuned that Personnel would have pushed the Ambassador-A into a higher crewing category of both Enlisted and Technicians and into higher build and refit resource cost categories.

Thankyou for your interest, Admiral."

As the Vice Admiral moves away, Lieutenant Galan catches Rear Admiral Leslie's attention and motions to join him and the Councilor. Pulling up a small holodisplay, he checks for attention but everyone else seems busy filing out, hobnobbing or celebrating a successful presentation.

"So... the original computer core from Kirks' original Enterprise. That's some history, right there.
Let me ask you, Admiral Leslie, what do you think of the chances of the Enterprise and perhaps the Ambassador being refit at Utopia Planitia? High? Now, I think you were going to ask me a perceptive question about the revised coolant system?"

[Leslie mutters something affirmative sounding]

"Why yes, as you astutely note Admiral, this is a lower-performance coolant design installed to reduce costs on new-build Ambassador-As, but such replacement does carry a cost in the refit. So, an existing ship under refit, with the M/AM refinements but retaining the higher performance Yoyodyne coolant already installed, has... let me see... retains a little over 1.5% additional Warp Core output from the coolant system compared to the Ambassador-A. Look at that. 1.5%, the power consumption of a secondary core. And, other than parts commonality, the older coolant meets all performance metrics. Simply an odd artefact of the design process. I understand that you are a fan of replicators, Admiral, so you might find it of note that the updated Mark VIII Replicators are certified to produce all field-refittable components required for both coolant designs.

Interestingly, 50-year-old objects like the original Enterprise core now count as an 'Antique' under an old Terran system that I believe made it into early Federation articles. Of course, curating an 'antique' of such historical significance is properly a role for the Officers of the Starfleet Historical Bureau, not Enlisted or Technicians. The Ambassador-A has roster room for a few additional officers.

Unfortunately, we in SDB hold no sway with Personnel, their crew banding thresholds are hard as reinforced duranium. But I have heard it said that even duranium weakens in the presence of Romulan ale.

You two have a good day, Admiral, Councilor."

Edit- SDB Designer notes- an Amby-A with the secondary core and retaining the Yoyodyne coolant costs the same 120/110 to refit, though the new-build cost goes up +10/+10 (thresholds are a harsh taskmaster). Aside from the cost, the real problem for a refit ship retaining the secondary core is the increased E and T crew. If they were instead categorised as five Starfleet Historical Bureau Officers, for the antique 2270s cores installed on the original-spec Ambassadors... The secondary core provides absolutely no increase to the ship stats.

Is the design link on the wiki (Design) fully updated? Because as far as I can tell it shows an SR build cost of 260.06 rounding up to 270, which doesn't agree with your posted SR build cost of 260. Is there some part that will be getting cheaper and isn't reflected on that design sheet?

Tangentially, I think we could at least get the required power for keeping the secondary core if we set the research team 40 Eridani A Shipyards (which should free up this year) to 2330s EPS safety, which I think should unlock T4 EPS parts to free the needed power, and can complete in time for this refit. No clue how to deal with the extra crew costs without sacrificing a stat point somewhere, though, and I strongly doubt there's any way to keep it without raising the refit costs.

You need to be using the most recent parts list. Check over here to get that working. Also, hello! Welcome to Sufficient Velocity! :D

T3 shields got a small cost saving last year that's in the latest 2324Q1 parts file.
 
Omake - The Caerliss Sets Sail - Usili 2.0
So, this was inspired a bit from Iron Wolf mentioning that the Honiani have been affiliates long enough to reach Captain rank, but I feel I'm missing something in this omake.

The Caerliss Sets Sail

November 15th, 2322

Eda Oraso woke with a jump, breathing heavily as the freighter shook in warp. Taking a look at the clock, she groaned out softly, getting up. If the freighter's schedule held accurate, they'd be arriving in Sol within the next eight hours. Then once they were docked, she'd be off to San Francisco to meet with Starfleet Personnel Command for the discussions of her... command. It was still so new, after the message that had arrived nearly two weeks ago when the Bull was heading towards Starbase 4 near Tellar for re-provisioning. She remembered having just gotten off-duty when she had seen the message explicitly from Starfleet arrive. Eda remembered nearly dropping the pad when she saw the line that said she was to be promoted to the rank of Captain, but then she saw the final line of the message from Starfleet:

"By order of the Office of President and Starfleet Command, you are hereby requested and required to take command of the Starfleet vessel, USS Caerliss, NCC-4108."

After that had been a meeting with Captain Solen. While it unfortunately had not been that of her previous CO, Kenneth O'Laughlin, to promote her, the promotion by Solen to Captain was something that she would treasure. That entire day was just special, having been promoted to captain and then assigned to command of the as of yet uncompleted Kepler-class frigate, USS Caerliss. The Honianian breathed in deeply, reminiscing and reflecting over that day as the freighter continued its way towards Earth.

Utopia Planitia
February 13th, 2323


A knock resounded against Eda's office door. "Enter!" she spoke, putting the PADD holding the latest of the details on one of the crew for the Caerliss.

A Starfleet officer entered the office. "Captain Orasio? I'm Commander Greenburg," the officer introduced himself.

"Good to meet you Commander," Eda replied, "It's good to see my new First Officer for the first time, and just for reference, it's Oraso, not Orasio."

"My apologies, sir," Commander Greenburg replied, "May I sit?"

"Of course," Eda spoke as her new first officer sat down in front of her. "While I have read through your bio, would you mind sharing your last posting?"

"Well," the Commander began with a breath, "I've been based at Starfleet Headquarters for the past two years as part of Operations Division after requesting a transfer from the Insight to a ground posting."

"And your posting on the Insight was as Chief Tactical Officer?" Eda asked to which she received a nod, "That was as a... Lieutenant Commander if I have it right?"

"Lieutenant Commander and Commander," Commander Greenburg spoke, "I was posted on the Insight as the Chief Tactical Officer starting as a Lieutenant Commander and promoted through as a Commander for nine months before I requested the ground transfer."

From there, the conversation drifted onto a bit of their respective backgrounds before the Commander raised a question about one of the objects present on her desk. The object was nearly a hands length tall, sitting on a rounded base. From the base, three metallic support pieces spiraled up to support a half-sphere in which the inside of the sphere stood empty. "It's a jalis," Eda said, "How familiar are you with well... Honianian spirituality?"

"A little bit, in terms of the call towards self-reflection and improvement on a personal level," Commander Greenburg replied.

"Well, it relates to Lakhept. For some Honianians, as part of Lakhept, there is the belief that as part of Lakhept you, for a lack of a better descriptor, write upon your flaws as part of your self-reflection and then burn it within a jalis. It serves as a function to 'cleanse' yourself."

"Thank you," the Commander spoke, and the conversation shifted back to where it had been before.

Utopia Planitia Shipyards
June 26th, 2323


"That's one unorthodox ship design," Greenburg mused, looking through the windows of the workpod as it slowly drifted by the Caerliss.

"I would have to agree with you there, Commander," Eda agreed, seeing just how... Starfleet-like it was, the smoothness and rigidness, "It is rather... different compared to a Centaur."

"Yeah," Greenburg spoke, "Especially having the bridge on the bottom of the saucer and the deflector dish up top. Going to be interesting if this is meant as a one-off, or if Starfleet is looking more towards shifting to it."

Eda nodded, staring at the Caerliss. Like every Starfleet vessel that she had served on prior to this, it bore a metallic grayness and an aesthetic of purpose. They were so unlike that of the ships that she had seen as a child and teenager, one that bore an aesthetic of beauty. Even now, that was something that she had never gotten used to from Starfleet. But as Eda took a more careful look at the Kepler that was to be her new ship, if there was one thing it was, it was squished. Having built the engineering hull in line with the saucer had made the ship look squished compared to what seemed like every other Starfleet vessel in service.

"Any updates on the crew training so far, Commander Greenburg?" Eda asked as the Commander adjusted the workpod to head back towards the main portion of the shipyards.

"Going alright. Lieutenant Commander Skagh is rather annoyed by the design of the Keplers with the deflector dish up top along with the shuttle bay in the front and how it's unlike any other ship we have in the fleet. He's remarked over the need to work in retraining some of the crew, along with himself, in a ship configuration like that considering some of the issues. Both Lieutenant Commanders Mrr'rasa and Jalian have reported both of their departments proceeding alright in training. Commander Saer is rather pleased with the scientists that will be under her command. Training in Command is proceeding smoothly."

"Excellent, keep me updated if we have any issues Commander," Eda responded.

USS Caerliss (NCC-4108)
Captain's Ready Room
October 15th, 2323


Captain Oraso groaned, as she finished through yet another series of paperwork. 'How is there even more paperwork I had to handle than as the XO on the Bull?" she thought, checking the time, 'Looks like it's for the first department meeting onboard.'

And with that, began arriving the department heads. First to arrive was her Chief Tactical Officer, Lieutenant Commander Mrr'rasa, to which she nodded following her arrival, only to be followed by her Operations Officer, Lieutenant Commander Jalian, and her Chief Medical Officer, Lieutenant Command Sh'zalrin. Then came her Chief Science Officer, Commander Saer, before she heard the words of what seemed like a sharp discussion appearing just as the door shut behind Saer. "Skagh, look. I'll talk to the shipyard to get a replacement for that warp coil," Commander Greenburg spoke as he entered the room aside the Chief Engineering Officer, Lieutenant Commander Skagh.

"Alright then, sir, but I'll hold you to it," the Tellarite spoke back, as both he and the Commander proceeded to their seats.

Seeing everyone having sat down, Captain Oraso stood up for a moment to begin. "It's good to see everyone, especially on the Caerliss," she began, seeing Lieutenant Commander Mrr'rasa and Jalian nod, "I'll want to begin an overview so far for the move on the Caerliss and any current issues with each of your departments going from Tactical, Engineering, Operations, Science, Medical, and then Command."

"Tactical is proceeding smoothly. We have about half our personnel, those principally assigned to ship defense onboard. We'll be having the rest of tactical personnel on by next week if I recall the schedule right," the Caitain Chief Tactical Officer replied, "We haven't seen any big issues, although some minor ones that could probably be dealt with internally."

"Engineering is fully onboard and working on proofing all the systems," the Tellarite Chief Engineer spoke, "There are a host of issues we're going to be needing to deal with, first thing as I was telling the Commander there is that the starboard nacelle work gang reported that one of the warp coils is cracked and going to need to be replaced before we can get started. Looks like they installed it wrong. We have some other issues, and the one thing of concern I'm going to be acknowledging is the setup Starfleet decided on for having the impulse drive up top and the bridge on the bottom. While I know it's been done, it's something I wouldn't prefer."

"Operations has got most of the crew moved over so far. I think once we get the personnel under astrogation brought aboard, Operations will be fully on," the Amarki Operations Officer spoke, "We've just had some minor issues with the turbolifts, but nothing to worry about. I will concur with Lieutenant Commander Skagh over some of the concerns I have with the deflector."

"Acknowledged on your concerns with the deflector," Captain Oraso said, "I'll also be getting Utopia Planitia to replace that warp coil. Commander Saer?"

"Science just has the assigned personnel on the computer systems onboard. I'm expecting the rest of the department to be on with the rest of Tactical," the Rigellian Chief Science Officer spoke, "No issues identified so far yet by any of the people in my department."

"Medical is slowly filling in, and we've got the initial medical staff onboard. The rest are going to be filtering in throughout this week and next," the Andorian Chief Medical Officer spoke, "Sickbays are showing no real issues of note, but potentially some teething issues considering this is a new ship after all."

"Besides what Lieutenant Commander Sh'zalrin has described for Medical, Command just pretty much has about half of Security on along with the bridge crews. We'll be getting the rest of them on I think in the next two weeks," the Human First Officer spoke, "No issues seen so far from Command Department, so probably the worst thing so far that the Caerliss has is the cracked warp coil on the starboard nacelle."

"Alright then," Captain Oraso spoke, "Now that I've got that, moving on..."

USS Caerliss (NCC-4108)
Bridge
January 8th, 2324


Captain Eda Oraso walked onto the bridge, seeing Commander Greenburg already on the bridge and overseeing operations. "Captain," Commander Greenburg spoke.

"Commander," Oraso acknowledged, "Status of the Caerliss?"

"Just went around the horn. All stations report ready to go," Commander Greenburg responded, as the Captain sat in her command chair.

"Understood. Ensign, prepare to take us into warp."

"Aye Captain," the officer at the conn—an ensign and a Bajoran if Captain Oraso recalled right—responded, "Ready for the order."

"Let's head on out," she spoke, and with that, the Kepler-class frigate burst into warp.
 
Like every Starfleet vessel that she had served on prior to this, it bore a metallic grayness and an aesthetic of purpose. They were so unlike that of the ships that she had seen as a child and teenager, one that bore an aesthetic of beauty.
It's interesting, to me, Starfleet ships are elegant, in a minimalist sort of way. All grey and steel. But to the Honiani, it probably does look like a Cardassian ship does to us, all functional, without any other concerns.

Yeah. It's something I was thinking on in terms of how a Honianian would perceive Starfleet vessels considered their own vessels and what they represent. There's admittedly some more stuff I was thinking about to go on with that, and some thoughts that were bouncing around for how you might deal with such a thing like perhaps...

Get the Paint and Statues!

In the Emperor's Name, leave no bulkhead bare!

Yes. That was a thought I was thinking about in terms of 'paint', although more-so as certain areas for murals if anything. Although now I'm wondering what kind of botany space something like a Kepler would have and how much space is available for non-dedicated lab stuff to plant...
 
Lt Galan:
"I'm glad you asked me that, Councilor. Yes, it true that there is a considerable performance increase from turn-of-the-century designs, we in SDB consider this an exceptional design in that several milestone technologies come together over a few years to offer a major performance increase.

The poor designer standing in front of this committee with a future Ambassador-B proposal is likely to be offering a far smaller relative performance increase. Don't get used to this!"

We speculate that QTorps will be another big boost, but only to C, unlike Isolinear which provides a considerable increase all over. Combine that with T3 phasers, secondary phasers, Phaser Arrays and T3 burst launchers all being available for inclusion at once... I'd not expect to see these late-20s to early-30s performance gains again.

I get the feeling that TBG's Ambassadors, unlike those of canon, will be serving well into the 25th Century.

It is quite awesome to me that the Amby-A has already beaten the Sovereign class as it was stated at quest start in nearly every metric.

fasquardon
 
I like her description of the class as squished. As it does seem to be a more in line design than a standard Fed design.

Means the *actual* Sovereign will be un-bloody-believable.

Not really so much compared to the Centaur.



"Tactical is proceeding smoothly. We have about half our personnel, those principally assigned to ship defense onboard.

Is that to prevent the Captain from stealing the ship out of spacedock or to make sure the Captain has all options on the table if she does steal it?
 
Personal Log, February - er, Stardate 23565, Lieutenant Ettan Lecky - USS Oslo
(Human, male)

I don't much like the new captain. I don't really know her that well yet, to be fair, but she can't seem to help annoying me.

For one... it's a little thing, but she hums incessantly. Every time I've been around her. And as Ops-CON - er, Operations Officer - I'm around her a lot. Which... it'd be fine, I guess, if she had a decent singing voice, but she's pretty tone-deaf. Maybe I should suggest she get augmented vocal cords to go with all those other augments.

But more to the point right now... I'm fine with scheduling lots of drills. But I don't quite see why that has to include practicing formal dinners. Supposedly, it's so that we're prepared for diplomatic summits, but surely they wouldn't host one aboard the Oslo? Like, they're usually held planetside, right? With actual proper staffs to prepare the meals? That's how things went with Beyond. And yet, here I am, preparing to help the captain host a formal dinner with Councillor Hadd-Loa. Again.

... is she trying to seduce the councillor?

Am I imagining things, or is this a reference to Breq from Ancillary Justice by Ann Leckie?
