This was inspired by a topic in the general discussion board (
https://bg.battletech.com/forums/index.php?topic=64913.0). Other than hovercraft, I don't think there have actually been any published Clan water units. I'm thinking that they probably use units from the SLDF days, like the
Manta and the
Mauna Kea. With Clan Goliath Scorpion's underwater installations, I imagined that they created IIC versions of those SLDF units as better technology became available. Common to these units is additional torpedo launchers and targeting computers since the Scorpions emphasize accuracy.
Here's the

And here's the
Mauna Kea IIC. Note that this upgrade actually turns the littoral combat ship into a submarine, and replaces the autocannon with an ER large laser with a targeting computer:

Eventually these units would probably make their way throughout the Clans much like how the
Undine battle armor did.
