FWIW, I seem to recall an article in a popular technology magazine sometime back in the '60s about a similar tri-hulled dirigible being built in New Jersey(?), whose stated purpose was to distribute Bibles in Africa! Later, the authorities stepped in and charged the promoters with fraud.
That was probably Aereon Corp and the original intent of the tri-hull was to distribute supplies to Africa. The Navy was not enthusiastic as it had suffered some disastrous accidents from its early warning arsenal (blimp and ocean rigs) around 1960. I don't recall any fraud charges but might have missed it in the news.
But, growing up in the area, there were almost continual attempts to revive a blimp program. Visited Lakehurst NAS on a number of occasions. Getting financial backing was always a problem as there was no interest from the military and commercial applications were, well, of the type you mentioned - hence very limited.
