Back To The Future: Blimps?

Know anyone who thinks blimps would be a worthwhile addition to U.S. defenses against terrorists? In early June, Vigilis posted this:
Modernized blimps would probably do a fine job denying access to homeland littorals at costs the Pentagon could digest cheaply. Crew size is minimal and Al-Zarqawi's stash of heat seekers would not work well at much distance. Now, who wishes to scoff that our modern Navy would ever consider such folly?

Today, 5 months later, the Sub Report carries this rather uncanny revelation from Pravda:
USA develops gigantic airships to spy on Chinese and Iranian submarines- The Pentagon has evinced great interest in the erstwhile popular technology

The Walrus dirigible will have a classic shape, according to early concepts. The cross-section will look be an isosceles triangle with rounded corners. In modern usage, the terms zeppelin, dirigible and airship are interchangeable for rigid airships, while Blimp is an informal term typically applied to non-rigid airships.

Who cares? Unless bureaucracy takes over from DARPA, taxpayers may get economical bang for their buck. You will need to know if this program will be USN or AF supervised. Whoever gets this will likely get the starship Kennedy (NAFTA-11).
