school, heard the distinct sound of a submarine blowing its tanks.
All this state-of-the-art weaponry was waiting to be used once British ASDIC
and American sonar men pinpointed the location of a U-boat from its engine and propeller noise or voices and miscellaneous sounds inside the vessel.
The gallery has a life-sized reconstruction of an ASDIC
hut on a British destroyer.
For starters, it helps to understand what the ASDIC
is and how it came to be built in Toronto.
Capt Walker was a great exponent of team work, making very successful use of Asdic
, HF/DF (high frequency direction finding).
The present ones are obsolete on the basis that they are vulnerable to sonar and Asdic
resources and even radar and aircraft.
Fanatico (Michael Stoute) seals Hide's treble by beating Asdic
(Staff Ingham/Piggott) in the mile-and-a-half handicap.
A hydrophone effect was heard sounding like a torpedo and a strong asdic
(sonar) contact was made.
Four of the corvettes under his command either had new captains or were fitted with unreliable radar and short-range ASDIC
Another significant improvement was that she was fitted with asdic
, the Royal Navy's revolutionary new submarine detection device.
