I've read a few BT novels myself and a few contain accounts on space engagements. The engagements are small since the Succession Wars saw much devastation on the industries that the building of warp capable ships became nearly impossible that such ships were practically off-limits for engaging. However, by the time of the Fedcom Civil War, Warship production started picking up and space engagements involving things bigger than dropships start to happen.
The ships mount (naval grade) lasers, gauss rifles/ railguns, LRMs and maybe PPCs. The dropships (Overlord, Talon, Hrothgar) are mounted ON these Warships are also heavily armed. Those weapons are not as powerful as beam cannons and they will probably provide a more FS1 type of combat. Since shields do not exist in BT, the game will be very FS1-ish.
The Clan war aside, there are many possible scenarios.
1) Pre-Star League Era (little info)
2) uprising by Amaris,
3) Succession Wars (1-3),
4) 4th Succession War,
5) Clan incursion,
6) Fedcom Civil War,
7) WoB Jihad.
The most promising ones are probably 2, 3 and 6 in terms of space combat, simply due to the availability of Warship type combatants. Otherwise it is limited to fighters and egg-shaped ships.
