She was laid down on 12 September 1940 by Danziger Werft, Danzig as yard number 108, launched on 16 August 1941 and commissioned on 18 December 1941 under Oberleutnant zur See Ernst-Ulrich Brüller.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-407 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, a beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-407 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, (220 rounds), one 3.7 cm Flak M42 and two 2 cm C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history

The boat's career began with training at 5th U-boat Flotilla on 18 December 1941, followed by active service on 1 September 1942 as part of the 9th Flotilla. However, within 3 months, she transferred for operations in the Mediterranean with 29th Flotilla for the remainder of her service.

In twelve patrols she sank three merchant ships – including the 19,627 GRT on 11 November 1942 – for a total of , one merchant ship damaged of , two warships damaged (17,900 tons) and one more ship a total loss ; however, some sources claim that the damaging of is to be attributed to the Italian submarine Ascianghi.
