[edit] Diagrams
Perhaps the article could use some diagrams, instead of just pictures of the SSMEs.

[edit] Rename to Space Shuttle Main Engine
Space Shuttle Main Engine is a redirect to Space Shuttle main engine. Shouldn't it be the other way around? Cjosefy 20:07, 18 September 2006 (UTC)
[edit] The SSME after the Shuttle era
Removed the following text from the section, as I'm fairly sure it's outdated (and indeed, it completely contradicts the rest of the section) but I could be wrong so if anyone disagrees and wants to fit that back in somehow, feel free.
A new Crew Launch Vehicle, also known as ARES (Affordable REsponsive Spacelift) is in development. Three SSME are to be used on this vehicle. It is scheduled for a demonstration flight in 2010 and may see operation in 2018.

[edit] First throttling rocket engine
Honeywell describes the SSME as, "the first rocket engine capable of being throttled." If this is true, it should be prominently mentioned in the Introduction section. (sdsds - talk) 18:14, 9 August 2007 (UTC)
- The statement is clearly incorrect, as the Reaction Motors XLR-99 used on the X-15 was throttleable, as was the Descent Propulsion System used on the Apollo Lunar Module. Both predate the SSME by decades. Joema 12:23, 12 August 2007 (UTC)
[edit] Designation of the SSME as RS-24
SSME was originally designated as RS-24 according to Rocketdyne's own document, publication 573-A-100 New 9/99 "Liquid Propellant Rocket Propulsion Systems," page 26. RS-25 was a misnomer adopted early in the Ares program. The term RS-25 was used to refer to an expendable version of the SSME. However, it was later discovered that the designation RS-25 had already been given to a NTO/MMH thruster that was never fielded. By that time, it was too late to make the change, so RS-25 stuck. Technically the expendable SSME was going to be called the RS-24f, because it was going to be the 6th block upgrade (f). Attempts at editing the page have been rejected due to "uncited references." Sorry that a website can't be provided, but feel free to contact Boeing or Rocketdyne to request the publication requested above.
[edit] SSME Power Ratings
Can someone explain to me why(how) the SSME are normally flown at 104.5%? Doesn't 100% mean all/the whole thing. I mean when you eat 100% of a pizza, you've eaten the whole pizza. This question is just a question in general, I'm not questioning if the article is correct. I've seen this in many other places, I just don't understand it.

- Made an effort to explain this in article. See "SSME thrust specifications" subheading. Joema 15:46, 13 November 2007 (UTC)
