An over-engineered solution to a niche problem, but I really wanted to ship blue circuits...

This mod has two methods of operation, accessible via a startup setting. The default, and usually better approach, is "Proxy container" mode. This adds a new container called a "Rocketizer," which should be placed adjacent to a rocket silo. Anything put into the Rocketizer goes directly into the rocket's inventory, including things that would normally be rocket parts.

"Create parts" mode is the way the mod worked previously. It is a little more clunky but it still exists in case it is needed. It creates three new products: rocket control units (made from processing units), rocket frame sections (made from low density structure), and hypergolic mix (made from rocket fuel), and alternate recipes for the rocket silo that use one or all of these components to assemble the rocket. The Rocketizer becomes an extremely fast 1x1 assembling machine whose only purpose is to convert components to the new specialized rocket parts.

Although this mod doesn't technically require Space Age, it's basically pointless without it, so I've marked it as a Space Age mod.

If you like mods that help out with rocket logistics, you might also like Circuit Launchable Rockets, or if you'd rather not worry about rocket logistics, try Telogistics.
