The Problem of Firing at a Fleet Under Way with Long-Range Torpedoes.
(See p. 684, Whole No. 146, Vol. 39, June, 1913.)
A CORRECTION BY THE AUTHOR.
Ensign H. H. Frost, U. S. Navy.—In this article on page 684 of the June Proceedings 1913 there is the following: “When the course of the torpedo is at right angles to the line of bearing of the target ships, a large target will be presented, while if its course makes a small angle with the line of bearing, the target will be presented more or less end on and its width will be much decreased.” This is correct if the target ships are not under way, but this statement must be modified if the target is steaming at a considerable speed.
If the target be in line formation and the ships be dead in the water, a torpedo fired on a course parallel to the line of bearing would have as a target the side of the nearest ship in formation, which would be the smallest target a fleet in this formation could present. However, when the target is under way this is changed, as I will try to show by the figure below.
