Design
Corner Brook's displacement is approximately 2,200 tons surfaced and 2,400 tons submerged. Covered in anechoic tiles to reduce her detection by active sonar, the submarine is 70.3 meters long, 7.6 meters across the beam and has a deep diving depth in excess of 200 meters. The main hull is constructed of high tensile steel sections stiffened by circular internal frames. Equipment located outside the main hull is covered by the casing, which also gives the crew a safe walkway when the submarine is surfaced. The fin, which helps support the masts, serves as a kind of keel and provides a raised conning position.
Corner Brook has six torpedo tubes and can carry up to eighteen Mark 48 Mod 4 heavyweight torpedoes for use against surface and sub-surface targets.
Corner Brook's sonar sets allow her to locate and track ships and other submarines passively: that is, without transmitting on active sonar and thus giving away her location. She is fitted with radar for general navigation, attack and search periscopes (incorporating video recording and thermal imaging), and an electronic support measures suite.
The boat has two diesel generators, each capable of producing up to 1,410 kilowatts, and one main motor. The generators are used to charge two main batteries, each consisting of 240 cells. These batteries are used to power the submarine, which can reach a submerged speed of up to 20 knots (37 km/h).

Famous quotes containing the word design:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“What but design of darkness to appall?—
If design govern in a thing so small.”
—Robert Frost (1874–1963)
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
