Gauss Rifle X available towards the end of War of 3039, and the production Rifle shortly afterwards.
Med Pulse in production in 3037 IIRC.
Endosteel was mid 30s when I looked it up.
And while it may have been finalizing the -9D line we have I think quite a few cases where a cheaper/simpler model is produced for a couple of test runs before going to the more advanced design. Finally, Obj Raids has its own problems but it was also before the materials retcon happened, so now instead of '49-52 being when the IS recovered tech and a couple years to get it into production you now have earlier dates than '49 available for introduction.
Ah, you mean the prototypes.
I thought you were talking about something I hadn't heard of.
Those really won't help getting it produced earlier on Styk since even the Liao & Kurita factories didn't have the Victor-9K up & running before 3049 based on the MUL.
The Objective Raids quote of the line being ready for production "soon" with an in year date of 3054 pretty much lines up with the other fluff about the Tao Styk factory.
We know it was destroyed by retreating cappies in 4SW.
We know Davion rebuilt it to build something different than its original line because it was such massive destruction that it was nearly a full rebuilt.
That something was chosen to be the Victor after they lost the Quentin factory in 39.
I don't know how long it takes to build a fully functional mech factory from the ground up but if they didn't start it till after the lost Quentin then that puts it at 15 years to complete.
That "seems" slow but then again, I think we have some quotes in fiction of some similarly long construction times after factories were destroyed so I wouldn't be surprised .
