Larson Class Starship

Apparently there was one more starship type that Season 3 of 'Strange New Worlds' included in a couple of episodes, but kept far (far....) in the background. It would seem to be a canonized and SNW-ified version of the Larson class from the FASA Star Trek board games which uses the primary hull of the Malachowski class as a basis. Once again, my diagrams are largely conjectural. ¯\_(ツ)_/¯
