The primary advantage of airships over conventional aircraft is that they can stay aloft almost indefinitely without refueling. An AWACS version of a lighter-than-air craft would be capable of providing continuous radar coverage of an area comparable to that covered by the E-3A with a single inexpensive vehicle. Since it can remain on station for weeks at a time, one might even develop it into sort of an airborne AEGIS by using fiber-optic data links to interface with ground based weapons directors and AAW/ASuW. As far as anti-submarine warfare is concerned, helicopters tend to be our most effective ASW platforms at present. Their primary limitation is range. An airship would be the equivalent of a P-3C with helo-like loiter capability and unlimited range. If airships are capable of sustained speeds of 40+ knots then they will make relentless submarine hunters.
