(2) Airborne HF DF Techniques 



Use of Existing DoD Facilities --Some signal intercept 

 information from the DoD data files may be available to the USCG, How- 

 ever, most DoD operations are mission-oriented and DoD aircraft are 

 flown in geographical areas of military interest. The feasibility of 

 assigning aircraft equipped for electronic intercept to patrol the 

 coastal areas of the CONUS would have to be explored with DoD since 

 there are few aircraft of this type. 



Unless there is an existing DoD mission in the geo- 

 graphical areas of interest to the USCG, it is reasonable to expect 

 that the surveillance cost would be the full cost of operating the aircraft, 

 or $1034/hr. 



Dedicated Aircraft --Estimated costs for an airborne 

 dedicated DF system are shown in Table 15.
