Invisible deterrent forces thus gain increasing importance, like the four Ohio-class nuclear ballistic-missile submarines now being converted to carry 154 Tomohawk LACMs each. But this number can only support one LACM submarine deployed, when the US needs at least four on continuous duty, meaning that about 12 LACM carriers plus escorting attack subs should be built — unlikely given the Navy’s current budget woes.

Given their nature I don’t think it beyond the realm of possible they’d just surge a few and have two or three at sea. Also they could just fire one dry and bring it back and replace it with a second. Plus you forget that SSBNs (US ones at least) have two crews per sub (they still do that don’t they?). Which means at any given time most Ohios are at sea. Having two or three of the SSGNs at sea during a conflict is probably nothing.
