There was a radio feature about the Zeppelin NG here recently.
These are rigid airships build by the Zeppelin company, who reactivated its old core business (Zeppelin Luftschiffbau GmbH) as a subsidiary.
The main business of Zeppelin (ZF and other companies) today is drive train and gearboxes for the automotive industry, but legally speaking it is the same firm that build the old airships, and the plant is in Friedrichshafen as well.
Sofar they build five rigid airships since 1995, a slow rate.
Next year they want to increase the size somewhat, but still no comparison the the old ones.
This Zeppelin, the 4th was used in London this year. It didn't cross the Atlantic in the air, but was assembled in Galveston and flew across the US to San Francisco.
AFAIK it is based at the old Hangars build for USN airships Acron and Macon.
What Skybird meant was the Cargolifter, which incidentally isn't dead at all.
The founder, like a true inventor of the 19th century tries again!
