Earl,

Which Fins do you have ? ( See PDF below, for details )

As far as I know, all Nike Fins are a built-up, ribbed, metal-core, with metal "skins" . . . Your description of a Phenolic material being used is very interesting !

Dave-

I’m not really sure what their application might have been. I’ve seen and looked through that document before and do not see the kind I have in it. Of course, that document is dated, so no telling what other fin types and construction materials may have been developed and/or used in the last 4-5 decades.

But, they are Nike size and shape and have a machined aluminum mounting stud protruding from the root edge. The fin cross section profile was sharp leading and trailing edges with a centerline high point. No metal cuff on the leading edge nor ANY exposed metal, save for that mounting stud.

As mentioned above, if I can ever get back to them in the storage room where they are I will make some photos and post. I would like to see some of them in action myself, if they could actually be descerned on a flight vehicle.

Earl,

Terrier fins were similar.

Can anyone provide a link or PDF of "The Malemute development paper?" I've searched and come up dry, but the OP refers to it as if it's something fairly readily available.

I had originally found it with Google - but Dave is almost as handy.

Very interesting. Looks like there were two types of Terrier fins used on the Terrier Malamute. Both with the same outer planform but one with two facets (the single raised centerline version) and one with 3 facets (called the "tactical fin" in the drawings). Apparently the one I have is the "tactical" version. I wonder if there was any significant performance difference in the fins or if one was simpler/cheaper to make. Again, very interesting.
