Good job! Winning SHO code coming to your inbox.

Now, everyone who knows anything about subs knows this:

Explain what is meant by Angle On the Bow....

HerbertMcCheese-Wang · 06-29-14, 08:20 PM

The relative bearing of the target from the bow of the submarine. Ie. straight ahead is 0°, moving from left to right is 90° etc.

Angle on the bow is the angle between the line of sight and the target's bow measured to port and starboard of the target's bow from 0 degrees to 180 degrees. It's difficult to describe it better, but there's an extract from the US Submarine Torpedo Fire Control Manual 1952 which has pictures:

To me, it's the angle that the watch crew would call if they sighted my periscope from their ship - angle off their bow.

Angle on the bow is measured from the bow of the target, not your own bow. An AoB of 0 would mean the target was pointed straight at you, but it could be anywhere, off your stern, off your portside etcetera. It's not a measure of where the target is to you from your point of view, but of where you are from theirs. For example, an AoB of 90 doesn't really mean anything, as it could be 90 degrees to port or starboard. In other words, standing on their bow, you'd have to look either 90 degrees to port or 90 degrees to starboard. If they were sailing in station with you off your starboard beam on the same course, they would have an AoB of 90 port.

The alternative version is that it's the measurement of your own bow from the periscope / centreline of the ship. If it's more than 0 degrees, you have had an accident:

As demonstrated by the USS Growler.

This measurement does not help with the other angle on the bow collision warning:
