Um, no there has been zero indication that they have submarines. I don't doubt thet they probably could, but subs are for specific scientific studies, smuggling, and war, especially that last one. Given that big scary Grimm lurk beneath the waves, I doubt there's a lot of incentive to pursue that technology. The one thing that could possibly justify it is the sweet procurement money of military R&D, but between the current peace, the likelihood of military missions attracting Grimm, and the fact that subs are weapons of surprise and offense, against ships and cities (the latter of which is quite rare in Remnant), there's not enough reward to justify the colossal risk.
