German submarine U-435

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-435 had a displacement of {{convert|769|t|LT}} when at the surface and {{convert|871|t|LT}} while submerged.{{sfn|Gröner|1991|pp=43-46}} She had a total length of {{convert|67.10|m|ftin|abbr=on}}, a pressure hull length of {{convert|50.50|m|ftin|abbr=on}}, a beam of {{convert|6.20|m|ftin|abbr=on}}, a height of {{convert|9.60|m|ftin|abbr=on}}, and a draught of {{convert|4.74|m|ftin|abbr=on}}. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of {{convert|2800 to 3200|PS|kW shp|-1}} for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of {{convert|750|PS|kW shp}} for use while submerged. She had two shafts and two {{convert|1.23|m|ft|abbr=on|0}} propellers. The boat was capable of operating at depths of up to {{convert|230|m}}.{{sfn|Gröner|1991|pp=43-46}}

The submarine had a maximum surface speed of {{convert|17.7|kn}} and a maximum submerged speed of {{convert|7.6|kn}}.{{sfn|Gröner|1991|pp=43-46}} When submerged, the boat could operate for {{convert|80|nmi}} at {{convert|4|kn}}; when surfaced, she could travel {{convert|8500|nmi}} at {{convert|10|kn}}. U-435 was fitted with five {{convert|53.3|cm|in|0|abbr=on}} 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 FlaK 30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.{{sfn|Gröner|1991|pp=43-46}}

In eight patrols she sank nine merchant ships, plus three warships and one auxiliary warship for a total of {{GRT|56,168}} and 855 tons.

;Convoy PQ 13

{{GS|U-456||2}} attacked and damaged the American freighter Effingham straggling the convoy. U-435 then finished off the abandoned vessel.

;Convoy QP 10

U-435 was more successful in April sinking both the Panamanian freighter El Occidente and British steamer Harpalion. The straggler Harpalion was finished off after being abandoned having been previously heavily damaged by Luftwaffe Ju 88 dive bombers.

;Convoy QP 14

U-435 had even more success when she was part of a combined attack on Arctic Convoy QP 14. She sank 4 vessels, comprising the minesweeper {{HMS|Leda|J93|6}}, RFA fleet oiler Gray Ranger, British Liberty ship Ocean Voice and American freighter Bellingham.

;Convoy ONS 154

U-435 continued her earlier successes sinking 3 vessels from ONS 154, the CAM ship Empire Shackleton, the freighter Norse King, the special service vessel {{HMS|Fidelity|D57|6}}: She was also credited with two landing craft carried on Fidelity when she was sunk.

She took part in eleven wolfpacks, namely:

• Hecht (27 January – 4 February 1942)
• Umbau (4 – 16 February 1942)
• Eiswolf (28 – 31 March 1942)
• Robbenschlag (7 – 13 April 1942)
• Nebelkönig (27 July – 14 August 1942)
• Ungestüm (11 – 30 December 1942)
• Burggraf (24 February – 5 March 1943)
• Raubgraf (7 – 19 March 1943)
• Trutz (1 – 16 June 1943)
• Trutz 3 (16 – 29 June 1942)
• Geier 2 (30 June – 9 July 1943)

She was depth charged and sunk on 9 July 1943 at position {{coord|39|48|N|14|22|W}} west of Figueira, Portugal by a RAF Wellington bomber from 179 Squadron.
