Interesting. Comments?
http://www.afa.org/magazine/Aug2003/0803milspace.html Air Force Magazine August 2003 Vol. 86, No. 8 How can the Air Force keep funding two major mission areas—air and space? Footing the Bill for Military Space By Benjamin S. Lambeth [EXCERPTS] Of all the uncertainties that currently affect the Air Force's prospects for realizing the near-term promise of military space, none is more crucial than the basic question of how—and at what opportunity cost—those prospects will be financed. Under current arrangements, USAF has increasingly come to shoulder the burden of funding what are, in effect, two major military mission areas — air and space — with an annual budget share intended for only one. Although all of the services benefit from the space product ultimately provided, military space funding comes almost entirely out of the Air Force's budget... Recognizing this growing Air Force predicament, the Congressionally mandated Space Commission concluded in January 2001 that America's military space capabilities are "not funded at a level commensurate with their relative importance." The commissioners voiced special concern that the Army and the Navy are the defense community's largest users of space products and capabilities, but the budget activities of those two services "consistently fail to reflect the importance of space." This pointed up a "dichotomy between the importance of space to the Army and the Navy [and] the funding commitment these services make" which "needs to be addressed..." An aggravating factor is that space applications have become increasingly expensive as the US defense establishment has become increasingly dependent on them. One seemingly intractable cause has been the high cost of space launch, which has imposed a limit on the rate at which the US can expand its military assets on orbit. The constant-dollar price of getting a satellite to low Earth orbit has not changed much over the past two decades. The cost per pound to LEO for most commercial satellites now on orbit ranges between $3,600 and $4,900, depending on the altitude and character of the orbit. The cost per pound for getting a payload all the way out to geostationary Earth orbit is considerably higher—$9,200 to $11,200. Furthermore, the prospect for any substantial diminution in launch costs over the next 10 to 15 years remains dim because of the unalterable physics of chemically fueled, rocket-based launch. There is little near-term technology offering any promise of circumventing this problem. One mitigating factor is miniaturization. It has slowly but inexorably increased the functionality of each payload pound on orbit, making possible the development and launching of smaller satellites. A decade ago, military satellites typically weighed between 5,000 and 20,000 pounds. Now those going to LEO usually weigh between 500 and 2,000 pounds. This means that the cost-per- pound issue may turn out to be less pressing in the future. Further compounding the continued high cost of space launch is another factor. The Air Force is facing an acquisition challenge of the first order due to the block obsolescence of many on-orbit systems now in service and the emergence of a new generation of replacements. Virtually every major US military space system is due for an upgrade or replacement over the coming decade, at an estimated cost of some $60 billion. These include the Global Positioning System satellites, all military communications satellites, and the Defense Support Program constellation of missile-launch sensors. |

(Allen Thomson) made the phosphor on my monitor glow in such a way as to indicate that: (Rand Simberg) wrote Many Air Force types are as ignorant of the source of high launch costs as people at NASA. It has nothing to do with liberal or conservative--it has to do with not understanding the issues. Might there not be an opportunity here for you, perhaps with some other CATS-knowledgeable people, to write a letter to AFM pointing out that there is no 11th Commandment that says "LEO launch shall not cost less than $3000/lb."? Do you think that AFM has any influence over policy? It's a serious question--I really don't know. If the USAF is actually starting to think it faces a serious cost-of- launch problem, maybe someone would take notice. If you were really, really, really lucky, perhaps something like SDI's support of DC-X might result. (Wild fantasy, of course, but perhaps worth the cost of sending a letter.) Perhaps, but I think that interesting things are happening regardless... I suspect that AFM is probably behind the curve. -- simberg.interglobal.org * 310 372-7963 (CA) 307 739-1296 (Jackson Hole) interglobal space lines * 307 733-1715 (Fax) http://www.interglobal.org "Extraordinary launch vehicles require extraordinary markets..."

Sabo made the phosphor on my monitor glow in such a way as to indicate that: Do you think that AFM has any influence over policy? It's a serious question--I really don't know. I'm not worried about AFM's influence over DOD policy. The greater concern is the nature of the article itself. The article is basically a synopsis of a RAND report to the Air Force by the same author. http://www.rand.org/publications/MR/MR1649/MR1649.pdf This is likely to have a more substantive impact than the magazine article and the author's same ignorance is expressed here too. (p. 158) Hmmm...I hadn't realized that the article was based on the PAF report. I figured it was just a AFM piece based on casual interviews. I guess I need to sit down and read the whole thing to see what else I disagree with, and then go down the street to Aerospace and argue with them about it. If I read the whole thing, I may write a review on my blog, which might be one way to get a discussion started. -- simberg.interglobal.org * 310 372-7963 (CA) 307 739-1296 (Jackson Hole) interglobal space lines * 307 733-1715 (Fax) http://www.interglobal.org "Extraordinary launch vehicles require extraordinary markets..."

If I read the whole thing, I may write a review on my blog, which might be one way to get a discussion started. Well, it is a 207 page report that I just skim read. Much of it is related to a discussion of "Is it aerospace or is it air and space" with the writer taking the position that they are separate entities and that the Air Force should consider them that way. I would assume that the fundamental place of disagreement after the stating of current costs of $3600-4900 per lb. to LEO and $9, 200 to $11,200 is the sentence: Furthermore, the prospect for any substantial diminuition in launch costs over the next 10 to 15 years remains dim because of the unalterable physics of chemically fueled, rocket based launch. Followed by: There is little technology now on the near-term horizon that offers any promise of circumventing this constraint. I think that was on pages 159 and 160 of the on-line report but the page notation at the top said 144 and 145. This was a very minor part of the report and the author really doesn't seem to be claiming expertise on that particular subject. Mike Walsh |

But it gets read by many serving officers and it's probably lying around in Pentagon waiting rooms so it's a good forum. Go for it. Indeed, in my days of Pentagon-crawling, many copies were in evidence. It's the house organ of the Air Force Association, http://www.afa.org/ , to which many current and former USAFians belong. It also runs yearly state-of-the Air Force issues with much useful information and stats, plus a "space almanac" http://www.afa.org/magazine/Aug2003/...acealmanac.pdf |

In this particular case it seemed to me that the author was repeating information given to him by other sources and that any major impact on Air Force planning by this belief probably exists elsewhere. Does the author have any real impact on Air Force policy? Or is this just another long winded RAND study. RAND puts out some good studies frequently, but I have seen enough of them to not be particularly impressed just because something originates there. Mike Walsh |

Stating authoritatively that we can't do better than the existing systems with rockets technology certainly makes it more difficult to get appropriations for attempts to do exactly that. Do you not consider that damaging? In this particular case it seemed to me that the author was repeating information given to him by other sources and that any major impact on Air Force planning by this belief probably exists elsewhere. No doubt it does, and of course, this report now buttresses it. And if someone in the Air Force has a different opinion, some ignorant Congressman can point to it now... Does the author have any real impact on Air Force policy? Or is this just another long winded RAND study. RAND puts out some good studies frequently, but I have seen enough of them to not be particularly impressed just because something originates there.
