I've noticed a couple discrepancies concerning the Virginia class US sub in the USNI reference files.
For the Virginia class, the starboard and port towed array names appear to be accidentally swapped in the ownship section reference page.
Also, the RA mod lists the Virginia's SPHERE sonar to be
slightly more sensitive than the Seawolf's SPHERE sonar, but with a lower washout max speed.
I thought that the Virginia was designed to have better sensors than the Seawolf?
Its HULL sonar isn't as good as the Seawolf's, and it has a lower washout max speed for its WAA vs the Seawolf's WAA.
(data taken from the RA mod USNI reference pages. Speed in kts are usable max speed before washout, and the number after is the SNR, i.e. -13)
It doesn't specifically list it in the USNI reference area, but the Virginia is supposed to have the BQQ-10(v4) sonar suite, which is the exact same suite that the 688i has, according to internet sources like those below:
Virginia specifications -

688i specifications -

If that's true, why aren't the MF Active, Sphere, and Flank (hull) sonar values the same?
I don't know if the BQQ-10 suite is supposed to be better than the Seawolf's BSY-2 suite, but in the stock 1.04 DW version, the Seawolf could passively hear a lot further with its sonar than the 688i could.
I would expect the Virginia to improve on that sensor range, but I don't know how to verify if the RA mod actually did that.
