Title 
Defense  Support  Program 
Budget  Activity   #4  -  Military  Astronautics 
and  Related  Equipment 
BACKGROUND  AND  DESCRIPTION:    The  Defense  Support  Program  (DSP) 
[Excised]  and  related  developments.  The  DSP  satel- 
[ Excised]  '       The  system  pro- 
vides [Excised] 
[Excised]  to  our  national  command  authorities  and 
other  designated  users.  The  system  also  serves  these  more  specific  purposes: 
[Excised] 
Two  ground  stations,  one  overseas  and  one  within  the  CONUS 
receive,  process  and  transmit  satellite  mission  data.  The  Joint  Chiefs  of 
Staff  have  designated  the  following  organizations  as  users  of  DSP  data: 
Continental  Air  Defense  Command  (CONAD) ,  Aerospace  Defense  Command  (ADC)  , 
Strategic  Air  Command  (SAC) ,  National  Military  Command  Center  (NMCC) ,  Atlantic 
Command  (LANTCOM) ,  Pacific  Command  (PACOM) ,  European  Command  (EURCOM) , 
[Excised] 
[Excised] 
Planned  system  improvements  are  intended  to  improve  the  useful  life  of  each 
satellite,  make  the  satellite  more  survivable    [Excised]    increase  the 
probability   [Excised]   data  will  be  available   [Excised] 
RELATED  ACTIVITIES: 
System,  Phase  II  (DSCS-II,  3  3110F)  will  provide  an  alternative  communications 
route.   Advanced  Airborne  Command  Post   (AABNCP,  6472 3F)  is  a  potential  user 
of  this  program's  data.   DSP  is  a  key  element  of  the  Worldwide  Military 
Command  and  Control  System  (WWMCCS)  and  is  related  to  the  other  elements  of 
the  WWMCCS.

WORK  PERFORMED  BY:  CINCONAD  has  been  designated  to  maintain  operational 
control  of  the  DSP  system.  [???]ation  and  technical  management  are  the 
responsibility  of  the  USAF  Aerospace  Defense  Command  (ADC) .  The  Air  Force 
Logistics  Command  (AFLC)  provides  logistic  support.  The  Space  and  Missile 
System  Organization  (SAMSO)  of  the  Air  Force  Systems  Command  (AFSC) ,  Los 
Angeles,  CA,  has  the  overall  development  and  procurement  management  and 
responsibility  for  the  DSP.  TRW,  Redondo  Beach,  CA,  is  the  prime  contractor 
for  the  space [Excised]  sensor.  Western  Development  Laboratories/Philco  Ford, 
Palo  Alto,  CA,  is  the  prime  contractor  for  the  User  Display  Segment  and  the 
Data  Acquisition  and  Communications  Segment.  Aerojet  Electrosystems  and  IBM, 
Westlake,  CA,  are  responsible  for  the  system's  software  development.  System 
Development  Corporation,  Santa  Monica,  CA,  is  responsible  for  software 
configuration  management  and  integration.  The  Martin  Company,  Denver,  CO,  is 
responsible  for  the  TITAN  IIIC  booster  and  Eastern  Test  Range  (ETR)  launch 
support.  The  Atomic  Energy  Commission  (Sandia  Corporation)  is  responsible  for 
[Excised] 
The  Aerospace  Corporation,  Englewood,  CA,  provides  General  Systems 
Engineering/Technical  Direction  support  to  the  DSP  System  Program  Office. 
PROGRAM  ACCOMPLISHMENTS  AND  FUTURE  PROGRAMS: 
1.    FY  1973  AND  PRIOR  ACCOMPLISHMENTS:  The  program  has  provided  for 
procurement  of  12  satellites  and  TITAN  IIIC  boosters,  construction  of  two  data 
processing  facilities  (overseas  and  CONUS) ,  user  display  equipment,  software, 
communications  equipment,  and  a  training  facility.  The  training  facility  is 
also  used  for  software  development  and  mission  data  analysis. 
[Excised] 
Future  launches  will  be  conducted  to  replenish

[Excised]  satellites  currently  deployed  when  operationally  required.  An  [?]SC- 
46  communications  terminal  has  been  installed  at  the  Overseas  Ground  Station 
(OGS)  which  will  enable  DSP  data  to  be  transmitted  to  the  CONUS  via  Defense 
Satellite  Communications  System  Phase  II  (DSCS-II)  communications  satellite, 
thus  providing  an  alternate  communications  mode   [Excised] 
2.  FY  1974  Program;  Expenditures  will  support  completion  of  modifications 
necessary      [Excised]      to  prepare  the  satellite  for  possible  universal 
(i.e.,  any  orbit)  deployment.  Funding  is  provided  to  modify  the  satellite  to 
enable  it      [Excised]      to  increase  the  satellite's  output  power, 
thereby  enabling  DSP  data  to  be  received  by  smaller,  less  costly  antennae;  to 
increase  the  satellite's  on-orbit  reliability;         [Excised] 
Further,  funding  is  provided  to  analyze  and  evaluate  collected  satellite  data; 
[Excised]       to  continue  support  of  DSP  Augmentation;  to  provide 
automatic  circuit  card  test  equipment;  to  procure  satellite  tracking  set  (STS) 
training  equipment;  to  provide  support  for  software  development;  to  complete 
ground  station  shielding  tests  and  make  necessary  shielding  repairs;  to  begin 
fabrication  of  an  initial  small  processing  station  (SPS) ;  and  to  procure  an 
IBM  360/75  computer  used  in  software  development  and  modification. 
3.  FY  1975  Planned  Program:   The  planned  FY  75  program  includes  expenditures 
for  initial  development  of  an  operational  modification      [Excised] 
[Excised]      to  continue  to  analyze  and  evaluate  collected  satellite 
data,  [Excised] 
[Excised] 
and  to  provide  continued  support  of  DSP  Augmentation.   Additional  funding  is 
provided  to  begin  development  of  software  to  begin  new  processing  stations, 
and  to  continue  fabrication  of  a  small  processing  station  started  during  FY 
74. 
4.  Program  to  Completion:  RDT&E  funding  will  support  continued  revolutionary 
development  of  the  satellite  system  in  support  of  DOD  requirements.  Primary 
emphasis  will  be  directed  toward  eliminating  or  minimizing  deficiencies 
discovered  during  operational  employment.
