World of Warships Torpedo Reaction Time List
World of Warships Torpedo Reaction Time List by Vecooo
I finally got the right formula (the way of getting to it is quite simple, you just use the “Law of cosines” and substitute the sides with speed multiplied with time) so here you go:
t = SQRT [(D2 ) / (vT2 + vS2 – 2 * vT * vS * cos(180 – α))]
SQRT = square root
D = detection range of torpedoes in meters
vT = 2,778 * speed of torpedos
vS = 2,778 * targeted ship speed
α = angle (0°-180°) the value of α is obtained from the crossing between the torpedo path and the ships path.
The value of the angle goes as follows: from 0° when the target ship is going straight towards the torpedos….to 180° when the target ship is going straight away from the torpedos. The formula is universal.
The reaction time shown in the table below is for 90° which is when the ship is travelling perfectly broadside to you.
