IMORANDUM FOR: Chief, Development Branch, DPD
FEB 1952
SUBJECT: Communications/Navigation Equipment
for A-12 Vehicle
REFERENCE: Secret IAC Report No. SP-326, dated
13 November 1961;
subject: "Communication, Navigation
Aids" A-12):
*USAF Declass/Release Instructions On File
and Rendezvous
1. Referenced report proposes the following Communications/
Navigation equipment for the A-12 Vehicle:
Equipment Use
a, ARC-50
Normal UHF voice communications
plus secure communications mode
for use in aerial refueling
including DME capability
b. DF-301 UHF/DF for rendezvous bearing
information
co 618T-3 Single Side Band Communications
d. ARC-15F Omni receiver for VOR Navigation
and terminal let down aid
e. ARN-41C ADF navigation and emergency let
down aid
25X1A
2. Not included in referenced proposal are provisions for an
SIF installation in the A-12. SIF Equipment is considered essential
for secure identification whenever interrogated by NORAD ground
stations whereby radar suppression and "hold-down" procedures can be
implemented. It is understood that space limitations prevent the
SIF installation concurrently with the other pment noted in
paragraph 1. alone. However, has reported that
the SSB installation could be ppe t interchangeability
with the SIF as required. This would provide for using the SSB on
operational missions and the SIF on extended test/training flights
when NORAD suppression is required.
