The ships of this class were ordered in March, 1915, as part of the Emergency War Programme of ship construction. The contract for construction was granted to Harland & Wolff, Belfast, who sub-contracted the construction of M32 and M33 to Workman, Clark and Company.

The main armament of the ships, two 6-inch Mk XII guns, came from guns originally intended for the five Queen Elizabeth-class battleships which became surplus when their aft casemate mountings turned out to be unworkable and were dispensed with.
