They are all lightweight torpedoes used on RN Ships with are range up to 11km. But removing anti submarine torpedo's just makes the ship a sitting duck if the helicopter is unable to fly because of bad weather or breakdown.It is incredibly dangerous for a surface ship to close within torpedo range of a submarine. Better to prosecute at arms length- hence the use of helicopters. Also, a submarine cannot outrun an aircraft no matter what it tries.
There are also surface ships equipped with stand off weapons that deliver a lightweight aerial torpedo at distance- like the RUM139 ASROC.
These both render full size surface launched torpedoes a bit redundant.
