The Gui-class submarine is a series of diesel-electric multipurpose attack submarines currently being built for the Monsilvan Navy by Wantao Industries. The Gui class is the final phase of a Monsilvan attack submarine program, a three-phased program to build more attack submarines for the Monsilvan Navy since 1994.

Two of the Gui class are currently in operation by the Monsilvan Navy.
