Columbia Nuke Subs; Obsolete Sooner Than Anticipated?

The five Columbia class subs the federal government ordered will cost about six billion each. The carry 17 Trident missiles, are vert quiet and have a nuclear reactor good 42 years. Still their value is dubious.

  The sky is being filled with tens of thousands of satellites and the number will increase. Inevitably most nations that matter will have instant infrared detection of missile launches and presumably a million AI piloted drones able to attack missiles on the way up and down.I wonder if human operated subs will be obsolete in a decade. If so the subs will have little defense value. Nuking the world seems a witless political direction anyway.
