Why armed naval trimarans remain unusual

The Independence-class LCS combines a trimaran form with the deep internal hull volume that naval vessels need.

Question

How often have trimarans been used as armed naval vessels?

Short answer

Rarely; the Independence class is the main modern example, and it works because its central hull provides much more depth and volume than a superficial trimaran silhouette suggests.

Notes

Armed naval trimarans have been rare. The research vessel Triton was unarmed, while the Independence-class littoral combat ships provide an armed example. Their deep central hull answers a recurring naval requirement for internal volume. Future warships could use the form more often, but the discussion leaves that prospect open because combatants still need substantial enclosed space.
