Project history

Fire support ships in hulls of medium tank landing ships of LSM class. First 12 ships differed from a prototype only by installation of big number of rocket launchers and 127mm gun aft. Subsequent ships had superstructure transferred from starboard side to a stern; an open landing deck was liquidated, and upper have made continuous, having placed on it 127mm rocket launchers and 127mm gun before a superstructure.

Modernizations

None.
