Justfrank, it was mentioned in a news release last Fall which has been deleted. I will try and find some posts which specifically discussed this reference to "naval battle groups" (more than once, I might add), but I don't have the premium feature and it will take some time, which I don't have much of today. The comment in the deleted news release specifically discussed lower altitude airships and mentioned "naval battle groups" as one possible use for such airships. I also believe it was the first public mention of developing lower altitude airships by the company.
