Specifically on their cruisers, yes. 3 with barrage or 4 with torpedo, plus two for an assault bridge. Or, of course, up to 8 tubes on an assault/BR cruiser with a flight of torpedo BRs, since Liir torpedo BRs are double-barreled. No one of their cruiser sections has an unbeatable number of tubes, but they're tied for most tubes on both command and mission sections while no other race is.Liir in general has more torpedoes launcher on their starship than anyone else. I think their cruiser have 3 torpedoes for mission while everyone else has two.
Their DNs, on the other hand, still boast the hilariously large fixed beam batteries. Like, 10 on a Barrage mission section. Bear in mind here, Liir drives are inertialess...their dreadnoughts are infamously nimble, so they might just be able to use those beams on targets smaller than a planet.
