I only utilize B5Tech on information that it clearly cites information from "Canon" sources, such as the series. Data such as specific weapon names, energy values, etc., I find is all BS anyway, so ignore it.
For example, on the White Star, anybody can clearly see from the series that it has the two wing-mounted Pulsars, the under-prow mounted beam, and the two prow mounted cannon. B5Tech adds names and "energy" damage values to these, but its generally good to ignore them. B5Tech collates and cites canon data to say the White Star has these weapons, then goes on to uncited and unsupported supposition to add data values like energy weapon values to it.
As for the Warlock and ship production. Why is it so hard to believe that a ship such as that could be produced in a relatively short period of time?
You gather that 1) They were already laying down the hull and 2) It would be "relatively" simple to remove specific systems and add in the artifical gravity systems that were given to EarthForce by the ISA/Minbari, and you assume that ISA engineers and specialists go to EA Shipyards with copies of artifical gravity systems to implement in "First Block" Warlock-class Advanced Destroyers, to both show EA how the systems work, and help the EA engineers learn to manufacture and adapt the technology to their specific needs and purposes.
For those who dispute that:

Further, Ivanova was given command of the one of the _First_ Warlocks to roll off the production line.
Like the "first series" of any ship, you assume they'll spend another year or so getting systems added in, shaking down the ship and "exploring" the intricacies of the new ship-class. In fact, every naval vessel has a "shakedown" period. You can assume the Warlock gets its artificial gravity added in during production and this "shakedown" period. So in reality, the Warlock underwent an additional year of "Sea Trial" which is the "last phase" of construction.
Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as “builders trials”), they are regularly conducted on commissioned vessels as well. In new vessels, they are used to determine conformance to construction specifications. On commissioned vessels; they are generally used to confirm the impact of any modifications.
Sea trials can last a few hours or many non-consecutive days.
