The Manila Class Escort Carriers are extremely fast to build

Title. I assume the production time of 86 days can't be right.

I've had a quick look at the code, and it appears the base build time of the last three models is 300 days (the first three take something like three years), so I'm not sure why it's only 86 for you. Do you have a save where we can see this in action?

Ah, I see what happened - it's the assembly line techs. Those are set to apply a 20% construction time reduction, but what it actually does is check the first model, take 20% of its construction time, and applies that number to every model of that type. So since the first model takes 960 days to build, but the later ones only 300, the later four get a massive discount. Darkest Hour Full has fixed that, but those fixes didn't get ported over to KR before, it's actually one of the things I'm working on right now.

The construction time was still very short before the ship assembly line tech was researched - 238 days and 0.2 IC vs 855 days and 1.2 IC for the Whitehead class. Surely that can't be right?

Base construction time for CVEs from the Manila-class forward is 300 days, down from 1080 or so for the preceding model. The big difference is carried over from the initial release version of Darkest Hour, I'll check whether it's been changed when I get home, but it looks like it's a consequence of the CVE line essentially being two separate things, the earliest models being the early experimental carriers like Hosho and Langley, which changes to the WWII-era mass-produced actual escort carriers halfway through. In that sense, the construction time and cost plummeting like that makes sense, considering these ships were specifically designed to be super cheap and quick to build, it's just a bit odd because the first part of the tree represents something completely different. I don't know when I'll get around to it, but that's one of the things that should no longer be a thing when I rework the tech tree.

I don't know offhand where the other reduction comes from, the 238 days instead of 300.
