Actually, some thinking about the Small ship/big bay issue, and looking at the numbers, too, leads me to think that much of the concern is simply due to the name. A PA bay is a pretty big deal for a small ship (at high tech), to mount in HG*, and so seems quite scary on first discussion in MGT;However, it really looks like the MGT 50t PABay is much less dangerous than its HG counterpart Looking at both MGT damage values (the equiv of a triple beam w/. higher penetration), it really does appear much more on the lines of the old Barbette.
A high guard PA bay is a factor 5 weapon (at the introduction tech for particle beam barbettes or turrets) , the equiv of 10 beam lasers; the triple beam turret is a 3; an MGT bay is at
most a 4: damage equiv to a triple beam turret & a generous +1 for extra penetration. **
The UWP is a semi-log function, so a HG 50t bay is a
minimum of twice as powerful as an MGT 50dt bay, but a pretty good match for a barbette.
So, it seems even less of an issue that smaller craft can install bays.....if anything, one can argue that the MGT bay is a closer match to one of the HG1 10 ton bays...but
they no longer exist.....
*if it was allowed......
**I'm leaving out the +1 mod for the HG beam factor as the MGT laser would also need more damage if tech was to be included as per HG-so, i'm factoring that out, and using the PB values for tech at introduction of the PA turrets and barbettes. Yes, its a bit fluffy, but heck. Apples and oranges, anyway comparisons between HG & MGT anyhow
