The turbines were designed to produce 32,000 shaft horsepower (24,000 kW) which was intended give the ships a maximum speed of 33.5 knots (62.0 km/h; 38.6 mph).

They carried enough fuel oil to give them a range of 2,400 nautical miles (4,400 km; 2,800 mi) at 19 knots (35 km/h; 22 mph).

[5] T35 was ordered on 20 January 1941 from Schichau, laid down at their Elbing, East Prussia, shipyard on 20 April 1943 as yard number 1517, launched on 12 December 1943 and commissioned on 7 October 1944.

After working up for the next several months, the boat was one of the escorts for the heavy cruiser Prinz Eugen as the latter ship supported a German counterattack against advancing Soviet forces near Cranz, East Prussia, on 29–30 January 1945.

On 5 May, T35 helped to ferry 45,000 refugees from East Prussia to Copenhagen, Denmark, and returned to transport 20,000 more to Glücksburg, Germany, on the 9th.
