Early Products

Throughout our history, Rockwell Collins, Inc. has produced a multitude of products. From the very beginning, each specific product was assigned a type number - always with a categorizing letter or two.
We are presently logging some of the early products into a database. When completed, it will provide our readers insite into our product-line legacy.

There are 217 so far - it will take a while to capture them all!! In time we will be changing the way the information is displayed and maybe a search tool or two.
