Well, I don't
remember all the factors. But the Navy had always been involved in carrying war to the enemy
through carrier, task forces and so on. And that included nuclear war. There were nuclear
weapons on carriers. The Navy was developing short-range missiles, cruise missile types to go on
submarines for attacking the shore and for attacking other ships. And so it was natural to think
of putting missiles on submarines or other vessels. The first idea that I remember was to put
Polaris sub...was to put Jupiters on... In the early '50s the Navy saw the Air Force as running
off with the whole strategic mission which they had previously shared. And began searching
around for ways to get back in, stay in. And I don't know who got the idea, but the notion of
putting Jupiter missiles on submarines was born in conjunction these considerations. Everyone
recognized that was a... not such a hot idea. Big, enormous, liquid fueled missiles on
submarines just didn't appeal to anyone. And so from the very beginning people sought a way to
avoid that. To find some other better solution. The army, of course, liked it. Because it
provided a rational, an additional rational for the Jupiter which, from the very beginning was
under fire. But the notion of a solid propellant rocket was already in the air. The... the
efficiency of such rockets was rapidly improving. And the laboratories, and in particular at the
Livermore Laboratory, we had reached the conclusion that we could build a war head suitable for
such a mission that was much lighter than...the previous ones. And putting all those things
together made the Polaris program possible. Which meant a solid fuel rocket of a size that could
conveniently fit on a submarine with a warhead that could conveniently be lofted by such a
rocket.
