[silentwayIII]

I use the XXI in 1945 missions only. Its a deep water boat that has to driven very carefully because of its size and lack of maneuverability. In the rare instances when I can find a convoy to attack this boat can truly be lethal.

My tactic for convoys is to slip past the the screening escorts at 30-35 meters, go to periscope depth and fire a full salvo of torpedo's at 3-4 merchants. I then dive to 35-40 meters and head toward the convoy at 7-10 kts while reloading acoustic torpedo's. Once I'm within the confines of the convoy I travel at the convoy's speed, and general heading, and begin targeting merchants with the acoustic torpedo's. I fire to my left, for instance and then move to another location or column of merchants to my right always remaining at 35-40 meters and repeat the process again.

When I'm done...out of torpedo's or things are getting dicey with the escorts, I begin a spiral decent at silent speed with the convoy above me. Decend to 150 meters and then straighten up exit the convoy and continue to 260 + meter.

Again, the big advantage is overal speed and torpedo reload time. Because the silent speed creep motors are not modelled in SHIII the XXI is only as quite as other U-boats.
