I was unaware that a Mk 46 torpedo could be upgraded to a Mk 54 by using a conversion kit:

Smart design to build this capability into the Mk54.

They wanted a cheaper Mk 50 and one more optimised for littoral operations, so they took the sensor of the Mk 50 and put on a Mk 46 body - or at least that was how it was pitched when it was first mooted.

Sounds like the changes are mainly in the sensor/guidance package.  Warhead and propulsion tweaks were probably included so as to fit in the same body, for storage/launcher commonality.

Well, as far as I'm aware every launch system that can take a Mk50 could take a late model 46 as the latter replaced the former. It would have been a no brainer and very easy to ensure the Mk54 retained that compatibility.

Yep. :)

I take it that the UK is still using some iteration of Sting Ray?

That's an interesting point. From helicopters and frigates, yes, but we are buying Mk54s for the Poseidon. I am not sure what the current status of the Mk 50 is in US service, particularly as the requirement to engage deep diving and fast nuclear boats has returned.

There may be some money saved on testing, as I would think that Poseidon has been cleared/certified for Mk 54.

Mk54 is the standard torpedo for the P-8A. It is meant to get a winged, GPS/INS guided delivery variant for launch from higher altitudes.

I believe it is still in limited inventory for helicopters.

We are having to buy an entirely new stock of sonarbouy for poseidon as well. The positive side is we are going to have a NATO stockpile in the UK which we are going to share with the USN and Norway, so that might be a positive step.
