<strong>The</strong> Air Force had studied the standard spacecraft approach for<br />
several years and was conv<strong>in</strong>ced that substantial sav<strong>in</strong>gs could be<br />
realized, but to be able to support this position dur<strong>in</strong>g the FY 77<br />
budget review it needed an <strong>in</strong>dependent economic assessment, hence<br />
its <strong>in</strong>terest <strong>in</strong> hav<strong>in</strong>g the Rand study supported.<br />
<strong>The</strong> AACB panel<br />
on unmanned spacecraft also supported the need for an economic evaluation<br />
of the various standard spacecraft of both <strong>NASA</strong> and <strong>DoD</strong> that<br />
might be applicable for the Air Force Standard Test Program missions.<br />
While the Space Test Program Office emphasized throughout the<br />
study that it was not necessarily <strong>in</strong>terested <strong>in</strong> an outcome that <strong>in</strong>cluded<br />
its standard spacecraft design (STPSS), this position was, to<br />
some degree, contrary to the role that the Space Test Program Office<br />
had played <strong>in</strong> carry<strong>in</strong>g out its missions <strong>in</strong> the past. As <strong>in</strong>dicated<br />
earlier, it had been <strong>in</strong>volved largely <strong>in</strong> fund<strong>in</strong>g the development of<br />
its own spacecraft. <strong>The</strong> <strong>in</strong>teraction that occurred throughout the study<br />
verified that the Air Force <strong>in</strong>itial emphasis was <strong>in</strong>deed valid.<br />

<strong>The</strong>re were several motivations for Rand's participation <strong>in</strong> this<br />
study. First, although the standard spacecraft procurement decision<br />
Concurrent with the Rand study of the standard spacecraft, but<br />
<strong>in</strong>dependent of it, the Air Force Space Test Program Office and <strong>NASA</strong><br />
Low-Cost Systems Office jo<strong>in</strong>tly funded a cost study with Aerospace<br />
Corporation that compared the MHS and STPSS for one of the upcom<strong>in</strong>g<br />
missions, i.e., the Solar Maximum Mission (SMM).( 30 ) <strong>The</strong> spacecraft<br />
cost estimat<strong>in</strong>g approach used by Aerospace relied uporr the SAMSO cost<br />
model( 2 9 ) directly without adjust<strong>in</strong>g the results for the use of flightproven<br />
subsystems or other low-cost experience; this resulted <strong>in</strong> a<br />
unit cost for the MMS about twice as high as that used <strong>in</strong> the Rand case<br />
study (Fig. 6, Sec. IV). Although we were not privileged to the reconciliation<br />
of these divergent cost estimates by the Air Force and<br />
<strong>NASA</strong>, we understand that the Aerospace cost estimates were accepted<br />
as be<strong>in</strong>g very conservative and could be considered as an upper bound,<br />
assum<strong>in</strong>g that these spacecraft are purchased <strong>in</strong> the normal manner that<br />
other <strong>DoD</strong> spacecraft are purchased. <strong>The</strong> successful experience of the<br />
Air Force Space Test Program <strong>in</strong> acquir<strong>in</strong>g <strong>in</strong>dividual spacecraft at a<br />
cost considerably less than that estimated us<strong>in</strong>g the SAMSO model tends<br />
to validate the magnitude of the Rand cost estimates. A recent check<br />
with the <strong>NASA</strong> MMS Program Office confirmed that the <strong>in</strong>dustrial cost<br />
