2) Lada detection range for towed array seems to be 5 to 6nm, is it correct in your opinion.

No, the range is a lot more. It depends obviously on the SSP but 5 to 6 nm is too short in standard conditions. In RA you really really have to set the monitor gamma setting to an optimum value. Otherwise, and especially on subs such as the Lada and the new Akula II Improved that use red/orange color for signals, you might not see signals that are there. You have to calibrate the monitor correctly, if its a bit too dark, some really faint 50/60 hz tonals wil not be visibile at all. At subguru.com you can download the zip file containing Timmy g00 tactical manual, together with the manual is an image that people can use to calibrate correctly the pc monitor to use at maximum efficiency the sonar station.
