WEBF.....The Admiral is correct to point....but do remember one cannot sell the need for more and better Submarines without talking up the threat.
The Days of SOSUS and a Western Powers Attack Sub tailing Soviet Boomers the full time they were operating are gone perhaps.....but the public will be unknowing of the actual capabilities of the US DOD currently.
It is not only Russian nuclear Submarines that pose a threat....but now we have very quiet Diesel Boats been operated by several Navies.
