However, at one point the USET-80 was a reliable torpedo.
The differences between the Russian problems and the problems mentioned above is that those weapons fail because they are cutting edge with teething techinical problems, the Russian weapons fail because they were manufactered 25 years ago and are well past their overhaul dates.
In regards to the Akula's and other Russian nukes, I am very suspicious of their current operating capabilities, particularly their quieting, given the current state of the Russian nuclear fleet, and also the fact that I suspect the Russian's active quieting systems are particularly maintenance intensive even over and above the regular issues of keeping up nuclear boats.
