The T-75 class of four, were captured hulls from Holland that were completed to a Germanic States redesign with GS armament. Because a lot of the parts that would eventually be fitted were on the secret list, the hulls were completed to a certain standard then transferred to a Germanic States port for completion. This gave much longer building times as the Dutch workers were quite happy to sabotage whatever they could. The first units did not complete till the summer of 1942 and the other pair in 1943.
These ships were slightly bigger all round than the previous T50 type and the Commonwealth J-N class destroyers. Bigger guns, more guns, bigger dimensions, etc. The ships were well liked in service, the engines were more reliable than the GS Navy high pressure boilers that had proved a failure in service. During peacetime there was little strain placed on the machinery, but during wartime there was a lot of high speed running which put pressure on the machinery which it did not handle well.
