German submarine U-449

German submarine U-449 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She sank no ships.

She was sunk by British warships northwest of Cape Ortegal, Spain on 24 June 1943.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-449 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 AEG GU 460/8–27 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-449 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, and a 2 cm C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.

Service history
The submarine was laid down on 17 July 1941 at Schichau-Werke in Danzig (now Gdansk) as yard number 1520, launched on 13 June 1942 and commissioned on 22 August under the command of Oberleutnant zur See Hermann Otto.

The U-449 served with the 8th U-boat Flotilla from 22 August 1942 for training and the 7th flotilla from 1 May 1943 for operations.

Patrol and loss
U-449's only patrol began with her departure from Kiel in Germany on 1 June 1942. She headed for the Atlantic Ocean, via the gap separating Iceland and the Faroe Islands. On the 14th, she was attacked in mid-Atlantic by a British B-24 Liberator of No. 120 Squadron RAF. The damage caused was slight.

On 24 June, no less than four British sloops were responsible for her doom. HMS Wren (U28), HMS Woodpecker (U08), HMS Kite (U87) and HMS Wild Goose (U45) dropped a relentless wave of depth charges which sealed the U-boat's fate.

Forty-nine men went down with U-449; there were no survivors.
