Section A: Destroyers / Destroyer Escorts / Coverttes / Frigates

(a) Get close to them, more preferably <1500m

(b) Pop your periscope up, and open all your bow torpedo tubes

(c) Once the solutions are generated, input them into your fishs

(d) At this moment, you should be able to get very close to the warship (1000m)

(e) Fire a salvo to it. Use small salvo angle (You may wish to use magnetic detonators if weather allows for it) For T1, set speed to "FAST"

(f) Wait and see

(g) If the destroyers starts to evade (changing course and speed), that means that your torpedo are detected. Don't hesitate to rig for silent running and dive deep. (Pls notice that sometimes, even the destroyer starts evadion, he may not be able to escape from that fish.)

Section B: Other big stuffs

(a) Get close to target. Preferably <1500m

(b) Open torpedo tube doors, and fire a salvo to it

(No. of torpedoes needed for different ships vary. Usually more valuable ships such as carriers and battleships needs large amount to fish, however, for light cruisers, 2 working fish is enough)

(c) Wait and see

(d) After torpedo impact, destroyer will start to hunt for you. Dive deep and rig for silent running. Sneak away slowly. If you have BOLDS, try to eject 1 or 2. They help a lot

(e) Even the sonar contact of warships vanishes, don't attempt to surface at once, since other ships' radar may pick you up (especially in those heavy traffic places, where there are tons of patrol). Go back to periscope depth

(f) Only when you are >75km from the sinking place, surface and charge batteries, allow gas exchange... The most important thing --- put radar and watching crews on since planes will continue to search for you even though all destroyer have already left the scene
