Even if it ends up only 1/4 it's original size, that's a whole lot of folks, a whole lot of research power and a whole lot of industrial capacity. Don't think for a moment that Kingsford is going to be satisfied with being a 3rd rate navy behind the likes of Grayson, or the Andies.
He won't, but that's a multi-decade build programme. Building a cheap SD(P) isn't very difficult: just make a hollow core, add a reinforced door to one end, and a rail system to dump pods. A prototype can be constructed in 3 years from the moment they got their minds on the fact it was possible (which is probably some time during the war, in 1922). It won't be a good design and may be little more survivable in an exchange than Wayfarer was.
A proper pod-layer will take more R&D. So I'd say this non-half-assed, proper first-gen SD(P) comes out at T+6 years. But since they won't have yet the full design of the Grayson-style compensators, they'll be topping at 7.5 million tonnes (the Medusas were 8.5). The SLN will then order 100 of those which they can use to find out how to really operate an SD(P), while working on a second-gen SD(P) to begin to stand toe-to-toe to a Sovereign of Space or Adler-class SD(P), possibly superior to a Medusa. Those come at T+10 years, with an order of 500 in 4 years, perhaps massing 8 or 8.25 million tonnes (SoS is 8.75).
That would the SLN at 600 SD(P)s in T+14 years, which is 1936. With 600 SD(P)s, they'd be bigger (in quantity, not quality) than any of the individual navies in the Alliance/Union, except the RHN. They'd still be a far second to the Union as a whole, though.
The biggest problem they'll have is the actual missile. There are two big development problems for the SLN: the gravitic/quantum baffle and the power source. The latter may come out in civilian forms soon enough that SL R&D can extrapolate to military purposes given enough time, but the former will not. Until that happens, they'll be firing huge missiles, which will limit how many an individual SD(P) can fire. That means a GA/Union SD(P) will be a match for 2 or 3 SLN SD(P). Add to that Keyhole II and Apollo Control Missiles and the SLN will have a steep hill to climb.
In the end, I'd say the GA/Union manages to maintain a 3:1 quality differential for the foreseeable future, which means the SLN needs to get to 3500 second-gen SD(P)s in the active fleet before it can say it's no longer "second fiddle". If they keep the pace of 125/year on average after year 10, they'll reach that level on year 34 (1956 PD). At best, they increase the pace to 1000 ships every 3 years after the first 500, so they could get to the 3500 on T+23 years.
My old signature was a quote from David saying that the time from "Hey what's that" to "I Christen thee First Podnaught" for the SLN would be at least 6 years.
Yeah, as you said you can do a freighter with pod rails in a few months, but a proper podnaught requires a complete rethink on how you build the structure and armor a warship, and what you place where. It also requires automation technologies and a boost of firecontrol links.
The Largest SDs prior to the Advanced comp was the Gryphon, weighting in at 8.339 Mtons. The current RMN accel advantage is just shy of 50%, so it makes no sense to be concerned about falling any further on the accel curve when building an SD. So it wouldn't make sense to build them any smaller than 8.339 from an accel standpoint.
