About range, one thing can be said: in SHIII the active sonar range
is greater than their real counterpart. Another point is that the sonars modeled in game are an extropalation of the real equipement. As far io have understood from 1939 to 42 the ASDIC was of "searchlight" type
with only a 16° angle of elevation and a range of 2500yards from the mid-42 to the end of the war the "searchlight" type was backed by a "Q" type the two systems working together the Q type had a max range of 1200
yards and an angle of elevation of 65°. Don't forget that the "Searchlight"
type and the Q type could be trained to 360° horizontaly. The 147 backed the preceding two systems later in the war it was specialy designed to track deep submarines and had a range of 1000 yards.
In game the "searchlight" type is made as a brtish system represented
by the 123 A ,128 A, 144 A ( A for active) and the Q type is exclusively an US equipement. ALL have the same generic capacities wich have nothing to do with the real sonars only the range of detection are modified to show an upgrade of the allied sonars as long as the conflict progress.
The type 147 in game has nothing to do with the real one.
It's really a shame to see this state of things in a sim.
But now i am right now testing my theory about the angle of elevation
having given to the active sonar an min elevation of
135° and max elevation of 180° in the first test the DD pinged my sub
but lost me at my vertical. The angular values need to adjusted to be more in line with the real life.
