With the scrapping of the Marasti class destroyers, and the rerating of the former Austrian DDs, the Vifors as fast minelayers, the Romanian navy will have used up 27,560 light tons of the available 32,000 tons under the Constantinople treaty (4 vr 30s, 4 vr 31s, 4 vr 32s), the Romanian Navy has 4,440 tons left available under the treaty. It was decided in 1938 to build 4 1,100 ton destroyers based off the Peggy Brown torpedo boats built by Poland and Yugoslavia in the early 1930s. They were designed to act as leaders for the future Romanian torpedo boat and MTB squadrons to be built in the near future. Although displacing 40 tons over the allowable destroyer tonnage, the Romanians would officially rate them as 1,100 tons until the termination of the treaty in 1941.
