From the description of the Victory and Island classes it sounds like the former is similar to the current Frigate yards, and the latter is similar to the Governor and Escort yards.
From the description it more sounds like a few ships, not a full wave from a yard would lead to retaking those islands. Whats more its not like they would be used up maintaining our hold on those islands once taken. They would concentrate on one island and then move on to the next. Its a similar thought process that applies to using them in Eastern Paris.
The thing is unlike the Escorts or Frigates, these things can be concentrated as the tip of the spear for an assault and then used again elsewhere. The Escorts and Frigates, plus to a lesser extent the Hydrofoils and Governors, are committed to specific missions either guarding a convoy route or acting as fleet in being style defense forces. The mission they (the Islands in particular, and the Victory's to a lesser extent) are committed to is the taking of NOD islands: the Arctic Islands, the Caribbean, Hawaii, Indonesia, the Islands in the South Pacific, etc.
They are the key to starting the island hopping campaigns that will majorly secure some of our more vulnerable routes. We took Socotra on the sly from Mehretu during the Caravanserai's campaign against him, and thus made the route from Oman to South Africa far more secure. Doing the same in the Caribbean and Nova Scotia for the trans Atlantic routes, with Hawaii and the Southern Pacific Islands for the trans Pacific routes will do great work in getting to the route of the problem of the NOD raiders, with the Arctic Islands for the North Atlantic and trans Arctic routes (especially with Nuuk now online).
Such operations will do much to alleviate the stress we are going to see when, not if, when the raids pick up again during Eastern Paris. Or at the very least give the raiders a reason to keep their heads down. Yes these ships aren't going to be the linch pin in the initial landings for Karachi, but they are going to help, and then once the initial landings are secure they will go back to island hoping to steadily make the NOD raiders less and less of a threat.
I get the reasoning, but... here's the problem.
So, the Monitors, at least in a relatively normal configuration, barring a nat 100, or, for that matter a Nat 1, or a big pile of techs, are 7-10k tons displacement, and will take about as much time per ship as the FFGs you are building now. The LHAs are going to be roughly similar in size to your CVLs, and take about as much time.
The CVLs have a roughly two year build time for the first wave. In even the most
extreme aggressive shipyard construction scenarios, the latest we have a reasonable chance of getting LHA yards built is something like 2061Q2 or 'Q3, which means those hulls are barely hitting the water in time for 2063Q4 Karachi.
Now, people have pointed out that you can rush a ship into service fresh out of the yard. For the escort carriers, this is at least
sort of viable. Because escort carriers are designed to operate in relatively low-stress stretches of ocean, where Nod mostly fights with light forces and Nod attacks are infrequent. You are more likely to have time to work up the ship's complement, try things out to see if they work, fix any mechanical defects that only show up after the ship hits the water, and debug any impractical aspects of how the doctrine for using the ship interacts with its capabilities,
before all these problems become decisive flaws undermining the ship's performance in a major battle. After all, the main function of the CVLs, at least in the first wave, is simply to
be there and operate VTOL naval aviation, something we already more or less know how to do.
The LHAs' function is... not like this.
The LHAs are centerpieces for complex and intricate high-stakes operations, because amphibious landings are among some of the most difficult things to get right in all of warfare, and the consequences of screwing up are almost invariably a total disaster for the troops involved. To perform their mission of launching amphibious assaults, these ships' crews and the troops they carry must gain experience with a set of capabilities very different from what they are familiar with. All these capabilities must function together like a well oiled machine. Furthermore, many of these capabilities are out of the direct recent experience of our military, so we'll have to spend time making sure everything works in practice the way it does in theory, or revise our doctrine accordingly.
If these steps are not taken,
the LHA project is at risk, because of the very great danger that the LHAs would be sent into battle unprepared, someone would get their wires crossed or a charismatic officer in the program would turn out to have been wrong about something, and we'd end up with a Gallipoli or an Anzio on our hands, instead of a Normandy or an Inchon.
Even using our existing, less capable amphibious platforms and heavy doctrinal reliance on strategic airlift might be better than having a handful of unprepared LHAs. Because at least
we know what those things can and cannot do. There is significant practical experience regarding how those things are used, and we can reasonably extrapolate how to deploy them without disaster, or look at the situation and say "this will lead to a disaster, let's not go there." With the LHAs there is far less certainty.
As such,
I do not think it likely that we will be able to use the LHAs immediately upon their entering service. Not even for 'basic' operations. Amphibious warfare is simply too complicated for the crews to learn on the job. Carrier operations are too, but at least there we
have plenty of sailors experienced in carrier ops on larger ships, so some of the experience is transferable, and the light carriers themselves are under less pressure to do the job perfectly on the first try.
...
So I don't think that, even if we have an LHA yard ready in 2061Q3-Q4, we can rely on having
even a few functional, combat-capable LHAs by 2063Q4. The risks associated with rushing the deployment of new, first-in-class ships designed to do something as fraught and challenging as amphibious warfare are simply too great.
So
IF we are willing to delay our GO date to, say, 2064Q4 (about as late as we dare given the need to have
Karachi Phase 5 done by end of Plan), then maybe, maybe, we could have a meaningful LHA component. Not a handful of demonstration pieces that hopefully won't fuck up while operating their untried-in-practice amphibious warfare tactics and operations manuals under live fire from a bunch of Nod's finest, but an actual
force that is capable of being imapctful.
But if we're trying some time between the 2063 and 2064 monsoon seasons? Then I fear all we could hope for from the LHAs is that handful of demonstration pieces. Which might have a chance to at least participate in Karachi, with uncertainty as to whether they will succeed because this would be practically their first battle fresh out of the yard... But not to do much of anything impactful involving the seizure of various minor strategic islands as you outline.
I just don't think we can get this done in time to be impactful for Karachi, which means that while
developing and beginning the program matters, prioritizing it the way we do the escort carrier and frigate yards right now is probably a mistake.
I worry that rolling out the Advanced ECCM and Cloak Disruptors fast and around the same time, while letting us make a lot of wins quickly, would push NOD too far into a corner too fast and we'd see the scorched earth and mass terror/civ casualties tactics come out from every corner of the world.
You'd be putting a boot to the neck of every single NOD leader at once and they would all collectively lash out with far more force and far less abandon than before because you're basically forcing the ultimate do or die moment on them.
You are not wrong.
On the other hand, remember that in this instance, we are unleashing these technologies
against a single opponent. And in an offensive targeted against lands that aren't really part of that opponent's core territory.
I think that may actually work to our advantages. First of all, because the other Nod warlords must consider that if we are not,
right then and there, launching major offensives into their heartlands... it might be unwise to fire off a death-or-glory attack involving strategic weapons. After all, doing so
and failing somehow would be totally disastrous by inviting an overwhelming GDI retaliatory strike that they have no means of fending off.
Some of the warlords might seriously consider "is this a good time to panic and launch an ultimate do or die attack? Or is this a good moment to bide my time and hope to invent my way out of the disadvantage I am now at? Or is this a good time to start
negotiating with GDI?"
...
Coming out with both these techs right before a Steel Vanguard offensive would probably have the effect you describe. Nod would start losing in the field so rapidly that they'd have strong reasons to toss strategic weapons at us just to slow us down. But here, most of Nod isn't even affected and isn't losing territory. The one faction that
is losing territory is losing peripheral territory, territory they know GDI has a strong incentive to clear.
This reduces the implied threat, while still giving us a significant advantage that will affect Nod's strategic calculations in future (e.g. for a warlord, making it very inadvisable to launch a full offensive against us in 2064-65 to draw off GDI's attention from holding Karachi, no matter how much Nod India asks them to)
18 to 24 months construction time, then an uncertain but likely substantial work up period.
To go from start of the first batch in a shipyard to ready for independent operation is likely 3 years, but construction alone is about 2 years, max.
However, it's important to remember that GDI can just go 'we need these ships right now, when construction completes they enter service immediately'. It's not a good plan, of course, but they can do that.
As noted above, I am pretty sure it would be very unwise to try this with amphibious assault ships...
I think it is doable that we can have at least one yard for both Amphibious and Monitor, before Karachi. It does not need to be many, just one or two will help but Zone Armor is still priority.
Yeah, but if we push having those things, we're going to have to start cutting stuff from other goals on the list. What do you want to sacrifice?
SADN coverage in case Nod replies with strategic weapons?
Active cloak disruption abilities against Nod's cloak bullshit?
Having Orca wingman drones so that our light carriers, which we
specifically delayed starting and made to take longer to build so that they could handle wingman drones, will actually have the drones they're supposed to have?
