Navaho Missle
any one have digram of the Navaho.. Planning on getting one made. Not the booster just the main missile unit

You need the booster too. That dual chambered engine played a big part in the evolution of the Thor/Jupiter/Atlas engines.

Understand, but the main missile will be difficult to build.

Before they tried launching the ramjet powered Navaho cruise missiles atop the LOX/RP-1 (kerosene) powered booster rockets, North American built and flew several reusable turbojet powered Navaho test vehicles that were designated X-10 (see: and ). The X-10 vehicles were very similar to the Navaho cruise stages.

This book, "The Navaho Missile Project: The Story of the "Know-How" Missile of American Rocketry" by James N. Gibson (see: i?ID=1651 , and also has it) may contain three-view drawings that would enable you to build a scale model of the ramjet powered Navaho sustainer.

I started working on a model of this for NARAM 52 when by Russian GOA missile ran into some trouble but I then switched to a Nike Hercules at the last moment.

Below is a drawing which may help you create your model from. I've also attached a screen shot of the cad file I was working on. I generated many more cross sections using photos I've down loaded to get the correct shape of the missile since these drawing like most scale drawings don't show enough cross sections.

Just a reminder about Bob's great page.

And Tim Wilson's semi-scale BG at

Thank you for posting the drawings (they look "stair-steppy" on my computer, but perhaps not on other people's)--the dimensions are readily readable, though.

Even a scale-like/semi-scale Navaho model--like the red-and-white prototype model near the bottom of *this* page--would make a nice boost-glider kit. It should be easy to trim, having both the V-tail and canards up front, and:

The canted mid-body booster fins (they were canted on the real thing) could also, as with the adjustable pop pod canards on the Estes Astron Nighthawk boost-glider, enable the model's ascent trajectory to be programmable. As with the Nighthawk's canards, the Navaho booster's mid-body fins could be made with sheet metal trailing edges; the fins could be installed at a tilted "normal zero angle," and their trailing edges' incidence could be adjusted to program the boost trajectory (as with a normal model rocket, the booster's nose cone would pop off at ejection, and a streamer would lower it to Earth).
