The Prowler in the lore is described having amazing and unrivaled stealth capabilities. Can we expect the reproduction from Esperia to be just as good? Does the reproduction differ performance wise in any way?

Esperia is committed to living up to the legends, and the Prowler's remarkable stealth was one of its strongest assets during the various conflicts between the Tevarin and the UPE. In general, Esperia is motivated to maintain the "experience of the ship" when deciding whether to apply a technical update to the ship (read the brochure page, "A Break from Convention" for some background on Esperia's philosophy regarding reproductions in general).
