Update: While the photo and depicted product may be new, the concept of the Spike dated back to at least April 2009.
Just found this on TRF. The Navy's latest guided missile, the Spike, is approximately 25" long and 2" in diameter. At that size, it would make a perfect full-scale build. As I looked at it a second time, I realized that I have a home made 3" cone that could go on a great semi-scale version. Up-scale, that is. (I say semi-scale because, while the general profile is correct, the radius on the tip may be slightly off and it's length might require an adjustment to the body tube length.
