hey all,

have a quick question for our submarine experts. What is that piece of equipment on the USS Dace.



Is that a snorkel or is it a secondary periscope. I have not been able to find any line drawing that indicate what it is. I have looked on NAVSource and no luck.

thanks

Dave

Hi David,

That is the extendible radar SD antenna mast.

Cheers,
