Been a while everybody, hope all is well I have had the following photo for some time in my archive. It was and still is a oddity, as to this day I cannot find a solid explanation for what it is. That is to say, I might have a theory now, if you all would allow me. To my knowledge, the photo...

I apologize if the explanation turns out to be silly, but i'm looking at videos of the Kongsberg NSM. Test shots are seen launched and cruising with the engine intake on top, and then there's models at defense shows with the intake on the bottom. What is going on here?

Information remain rather scarce about the origins of the Penguin missile, adopted by US Navy as AGM-119. It was developped by Kongsberg and FFI, but little known about the early concepts. The same is true about its derivatives. Jane's mentions a coastal launcher prototype.

I posted this over in Army Projects yesterday but got no response, and it may belong more properly over here. I was wondering if anybody has ever seen any pictures of drawings of the Japanese "Submersible Guns" developed by the 10th Military Experimental Station in Murotsu in 1945 for coastal...
