So really it manages to pack all of an ISD-I’s heavy armament plus torpedoes, while forgoing the ISD-I’s secondary armament and point defense, which considering its size relative to an ISD its armament makes sense. The Profundity is just over 1200 meters and while its armament may seem underwhelming, it basically the armament of an ISD-I without the heavy quads, medium TLs, and only 1/6 the point defense but has like 12 torpedo tubes in compensation. The Profundity’s armament comes from the R1 Visual Dictionary, which has in my opinion the best technical data for an ISD-I I’ve seen.
