At your request, the Congressional Budget Office (CBO) has analyzed whether a difference exists between the Department of Defense’s (DoD’s) funding for science and technology (S&T) activities supporting unclassified space programs and its funding for S&T activities supporting other (nonspace) programs. The enclosed report indicates that funding for S&T activities supporting unclassified space programs has been less than S&T funding for other defense programs and that DoD’s plans for the future maintain that difference in funding. (Because of a lack of information, CBO’s analysis does not address the extent to which classified research might be supporting unclassified space programs.)

It is hard to extract meaning from this. The DoD is spending more money on other things than funding non-classified space research. Ok, makes sense. However we have no idea hwo much money they are spending on funding for classified space researcher. Given China's publicly broadcast ability to blow shit out of space, you have to hope there is some classified research going on.
