How ASDIC spread across interwar navies

Other navies generally pursued ASDIC-like underwater detection, but adapted it to their research traditions and manufacturing capacity.

Question

Did other navies use the same ASDIC system as Britain?

Short answer

They used broadly similar technology, modified by their own research and manufacturing capabilities.

Notes

Foreign ASDIC systems were broadly similar rather than exact copies. National research programs introduced modifications to the underlying approach. Industrial capability also determined whether fleets could produce and field a proper system. Some navies never obtained an effective ASDIC installation even when they understood the basic technology.
