Author Topic: What were the problems with the Delta III, and why did it constantly fail?  (Read 1624 times)

I was just curious about different input on this.

Also, what could have been done/what did Boeing do to combat these issues, and why was the program scrapped instead of continuing for a 4th flight?

The Wikipedia page on Delta III has a decent summary of it's short career, and several useful links at the bottom of the page.

Thanks for noting the article. 

I would argue that Delta 3 did not "constantly fail" as suggested by the thread title.  It succeeded during its finale.  The second failure was the result of an RL10B-2 manufacturing flaw.  If Delta 3 hadn't discovered this flaw, it likely would have afflicted Delta 4.  The first failure was due to an undiscovered roll mode.  That one was on McDonnell/Boeing.

The two failures are not the reason that Delta 3 was ended.  Consider that the first two Ariane 5 launches, in 1996 and 97, failed.  Now, after 91 launches altogether, we know how that story has turned out!
