For what its worth: 1.15 hits on average a turn from one nova on a closing kroozer
0.9 hits per turn on average for str6 torps on a closing kroozer, even with their abysmal turret rating.
Novas have minimum 30cm range, which means torps get another shot over novas if their captains choose to RO and not LO with the broadsides at that range.
Torps don't have the alpha strike capability, must RO, can be intercepted by torps, can be intercepted by fighters, can be dodged.
Novas can reduce leadership, slow ships down, scatter and damage other ships, and take out ordnance.
My only point is, one can't easily say that NC are lesser options to torpedoes, or,
'I don't always use my prow, but when I do, I make it a torpedo salvo'
