As a co-equal founder of Federation we see surprisingly few Andorians in Star Trek. I know Roddenberry wanted to get away from TOS during TNG, but that doesn't explain why we see so many Vulcans around. Vulcan seemed to have given up independent space operations early on but they are very well represented in the various ranks and departments of Star Fleet. Was an Andorian space fleet still maintained? We somewhat suspect that their space is near Vulcan and would be away from the Dominion War, yet Romulus should not be close to Cardassia and they were full combatants. Am I to assume that the generic twin nacelle ship design become the Federation standard sometime in the early 23rd century?
