Attack Periscope

The attack periscope is one of the two periscopes in the Type VII. It is located in the rear of the conning tower. The periscope can be raised and lowered by pressing W or S. It can only be extended to any height within it's range.

When extended the periscope can be used to observe above the surface while submerged at depths up to 14m. There are two zoom levels available, 1.5x and 6x. These can be selected using the mouse wheel. The periscope has a reticle identical to that of the observation periscope. The crosshairs in the center can be used in conjunction with the TDC to aim torpedoes, or to find the relative bearing of other vessels using the scale on the top of the view. The attack periscope also has a scale on the bottom which reads the true bearing. On the left side and on the bottom of the reticle there are graduations in centiradians. The scale on the left can be used to estimate the range to other ships by measuring how many centiradians tall a ship appears in the periscope. Divide the height of the ship by the centiradians, and multiply by 4 if the periscope is zoomed in. This gives you the range to the ship in hectometers. Because of it's smaller head, the attack periscope is detectable by enemy vessels at shorter ranges than the observation periscope.
