When the war moved to the American coast and the southern Atlantic, the Type IX was the weapon of choice. IXA, IXB, IXC, IXC/40.
The baseline early-war trainer. It features three bow torpedo tubes, zero stern tubes, and carries a maximum supply of just 5 torpedoes. It lacks an deck gun and possesses very limited battery life and fuel capacity, restricting patrols to areas close to Germany.

The Type VII is the quintessential "Wolf." This medium-range attack submarine forms the backbone of Silent Hunter III 's mid-war experience. It's a versatile balance between the small Type II and the large Type IX, offering a combination of firepower, maneuverability, and endurance that makes it the most common and beloved U-boat in the game.
Play the Type XXI for the novelty of being the apex predator. But the war ends in 2–3 months, and you’ll face advanced sonar (Fräulein) and homing torpedoes (FIDO, Mark 24) that don’t care how fast you are underwater. silent hunter 3 all submarines
The Type IX was designed for distant waters: the Caribbean, Gulf of Mexico, Freetown (Africa), and even the Indian Ocean. They were larger, slower to dive, but carried more fuel and torpedoes.
The Type IX is the "Lone Wolf" of the deep. This large, ocean-going submarine is built for endurance. It sacrifices some of the Type VII's agility for vastly superior range and a heavier torpedo loadout, making it the king of distant patrols to the American coast, the Caribbean, Africa, and even the Indian Ocean.
While the game has an auto-targeting feature, calculating torpedo solutions (speed, angle, distance) manually is deeply rewarding and maximizes your torpedo efficiency.
The Type XXI was the first submarine designed to operate entirely submerged. With a massive battery capacity, streamlined hull, and hydraulic torpedo reload system, it was decades ahead of its time. Only two saw combat before the war ended. When the war moved to the American coast
Extremely limited range and armament (only 2 torpedoes, no reloads). 🛠️ The Impact of Mods on Your Fleet
: The Type XXI can run faster underwater than most merchant ships can travel on the surface. It features a hydraulic rapid-reloader that can fire 18 torpedoes in under 30 minutes. Use the snorkel to cruise permanently submerged, fire from deep water using the sonar tracking station, and run at high speed to easily outmaneuver escort ships.

The first true "submarine" (meant to stay submerged, rather than a submersible torpedo boat).
The Type IX is a different beast . It takes over 45 seconds to dive to periscope depth—an eternity when an aircraft appears. Its large above-water profile makes it visible from farther away. However, with 22 torpedoes, you can sink an entire convoy and still have fish left for stragglers. It features three bow torpedo tubes, zero stern
This is the boat that Silent Hunter 3 was designed around. Excellent surface speed, decent dive time (25 seconds to periscope depth), and enough range to reach the North American convoy routes (AM52, AL18). The VIIB’s secret weapon is its diving stability —it maintains depth well even when running silent at 2 knots.
The Type VII is the backbone of the Kriegsmarine. It balances speed, range, firepower, and diving capabilities perfectly, making it the most versatile class in the game. : Medium-range offensive patrol. Torpedo Tubes : 4 bow, 1 stern. Torpedo Loadout : 14 total (including external reserves). Deck Gun : 88mm.
