what is the detection range of an asdic ping sonar

y dont find it please?

ASDIC maximum range was against a submarine at periscope depth, typically given as 2,000-2,500 yards (in ideal conditions, perhaps out to 3,000-4,000 yards), although average detection range during the war was more like 1,300 yards. For a periscope depth target, contact could be maintained down to 250 yards or so, depending on signal-echo merge. Contact on deeper submarines would be lost at greater distances, which was countered with additional mid- to late-war tech like "Q" and "Sword". However, ocean conditions could alter detection ranges based on depth significantly.

in km please ,sorry

1000 yd = 0.91 km
