SMS V46 was a 1913 Type Large Torpedo Boat (Großes Torpedoboot) of the Imperial German Navy during World War I.

In 1917, she, along with the rest of her flotilla, was deployed to Flanders, taking part in raids against allied shipping and the Dover Barrage, before returning the Germany.

V46 was interned at Scapa Flow after the end on the fighting, and after attempts to scuttle her on 21 June 1919 failed, was transferred to France in 1920 and scrapped in 1924.

[1] V46 was assigned to the Sixth Torpedo Boat Flotilla, Twelfth Half-Flotilla, of the High Seas Fleet of the Imperial German Navy when she participated in the Battle of Jutland.

[9] In January 1917, the 6th Flotilla was transferred to Flanders to reinforce the German torpedo boat forces based in the Belgian ports.

[11][12][13] On the night of 25/26 February, the Flanders-based torpedo boats launched a three-pronged attack against Allied shipping in the English Channel and the Dover Barrage.

While the German ships attacked Laverock with heavy gunfire and torpedoes (one of which hit the British destroyer but failed to explode), the British destroyer only received light damage, and the 6th Flotilla turned back for Zeebrugge, with the drifters of the Dover Barrage unharmed.

The 12th Half-Flotilla (including V46) became separated from the rest of the 6th Flotilla and therefore returned to base, while the remaining three ships of the flotilla continued on, torpedoing and badly damaging the destroyer Llewellyn before returning to base, while a merchant ship was sunk by the 2nd Zeebrugge Half-Flotilla east of the Downs.
