Byzantine Empire Colonial Ships

[Jefgte]

To comply with the rules (OA 0.9), the speed of the TGB800s is reduced to 25.2kts (was 27kts), they will be able to work with the old D750s (25.5kts) newly assigned to TGB missions.
No $ & BP changes in 1922 reports.

[The Rock Doctor]

Is there a speed bonus when the machinery is only 39% of normal weight?

[Kaiser Kirk]

Is there a speed bonus when the machinery is only 39% of normal weight?

Nope, that vessel is under the Cruiser architecture, not DD, so no speed bonus.

[Jefgte]

Speed bonus delete in TGB topic.

Why singles and not three twins or two-guns?

[Jefgte]

Why singles and not three twins or two-guns?

I think singles have a little higher ROF than singles, but gunners are less well protected. A hit on the upper turret can neutralize all the personnel of the 3 singles.

I prefer the 3T2 assembly.

[Kaiser Kirk]

More economical than a Destroyer and more effective in fighting against MTBs which proliferate in small Navies,
these TGBs can work with 27kts colonial cruisers.

The lack of a published Ethiopia navy is unfortunate, but it likely has quite a number
of light combatants to guard their coasts.


The carrier is interesting, I think to limited for my taste, but similar fighter carrier concept to the Bazdari class...  fun to see a range of options out there
