The Program 437 direct-ascent ASAT of the mid-1960s is well known, but it only came to my attention a few months ago. I was fascinated to learn that there was a variant called Program 437AP, that was designed to image Soviet satellites. It has long been known that this sub-orbital satellite inspector used components of the orbital Corona spacecraft. Over the holidays, I re-read the Program 437AP history, and began to realize that this had been more than a minor modification of the re-entry vehicle of the ASAT. It was a sub-orbital Corona-like vehicle, without the Agena section. I found little more than passing reference to this on the web, so I decided to investigate the likely size and configuration of the satellite inspector, and analyze one of its flight tests, all of which I have documented here: http://www.satobs.org/Program437AP/Program437AP.html There remains much more to learn about this unique vehicle, and the report raises a number of questions in that regard. I intend to make revisions, if and when better information becomes available. If you have historical information to share, or alternative interpretations of the available facts, I would be pleased to hear from you, on or off-list.
