SMS S33[a][b] was a V25-class large torpedo boat of the Imperial German Navy that served during the First World War.

She was built by the Schichau-Werke shipyard in Elbing, East Prussia, being launched on 4 April 1914 and was completed in October that year.

The new, larger, designs would, as well as being more seaworthy, carry a heavier armament and would be oil-fueled only, rather than use the mix of oil- and coal-fueled boilers that German torpedo boats had used up to then.

[4] The machinery was rated at 23,500 shaft horsepower (17,500 kW) and gave a design speed of 33.5 knots (38.6 mph; 62.0 km/h).

220 t of oil was carried, giving a range of 1,100 nautical miles (1,300 mi; 2,000 km) at 20 knots (23 mph; 37 km/h).

[6] On 15 December 1914 the German battlecruiser squadron under the command of Franz von Hipper set out on an attack on the British east coast towns of Scarborough, Hartlepool, West Hartlepool and Whitby, with the intent of drawing out parts of the British Grand Fleet where it could be defeated in detail.

[14] On 24–25 April 1916, Hipper's battlecruisers carried out another raid on the British coast, this time against Yarmouth and Lowestoft.

[15][16] S33 sailed as part of the 18th half-flotilla of IX Torpedo Boat Flotilla during the Battle of Jutland, again escorting Hipper's battlecruisers.
