SMS Warasdiner[a] was a destroyer launched in 1913 as Lung Tuan (Chinese: 龍湍), intended for sale to China.

In 1912, China placed an order for a single destroyer with the Austrian shipyard Stabilimento Tecnico Triestino (STT) of Trieste.

[1] Like the Huszárs, Lung Tuan was to be powered by two triple expansion steam engines, fed by four Yarrow boilers, rated at 6,000 ihp (4,500 kW), driving two shafts, although at 30 knots (56 km/h; 35 mph), the ship was slightly faster than the 28 knots (52 km/h; 32 mph) Huszár class.

[3][b] Although the Huszár class and therefore Lung Tuan were obsolete by 1913, the Chinese government ordered a further 12 destroyers from STT that year, partly due to the low price (£16,500 per ship).

[7] On 5 December 1915 Warasdiner was returning from another raid on the coast of Italy when she sank the French submarine Fresnel, which had run aground off Cattaro.
