She had a total length of 67.1m (220.1feet), a pressure hull length of 50.5m (165.7feet), a beam of 6.2m (20.3feet), a height of 9.6m (31.5feet), and a draught of 4.74m (15.55feet). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of NaNPS for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750PS for use while submerged.

The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-290 was fitted with five 53.30NaN0 torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.82NaN2 SK C/35 naval gun, (220 rounds), one 3.7cm (01.5inches) Flak M42 and two twin 2sp=usNaNsp=us C/30 anti-aircraft guns.

U-290 served with the 8th U-boat Flotilla for training from July 1943 to April 1944 and operationally with the 6th flotilla from 1 May. She was reassigned to the 11th flotilla in August. She was transferred twice more, first back to the 8th flotilla in late August, then the 4th flotilla in mid-February 1945.
The boat's initial foray, which was preceded by a short voyage from Kiel to Egersund (southeast of Stavanger) in Norway, began with her departure from the Nordic port on 1 June 1944 and finished at Bergen on 16 June.
She had been attacked by a Norwegian De Havilland Mosquito of No. 333 Squadron RAF on 14 June. Eight of her crew were wounded.
A series of brief journeys then followed, between Bergen, Kristiansand, Kiel and Gotenhafen (now Gdynia, Poland).
She departed Gotenhafen on 7 September 1944. After patrolling the Baltic, she docked at Danzig (now Gdańsk, Poland) on 5 November.
After sailing to Libau in western Latvia,[1] she departed from there on 1 January 1945, arriving in Kiel on the 29th.
