Great. Thanks!
I have a question to the forum experts regarding the clarification of avionics complement of the ROCAF RB-69A's versus the ordinary P2V-7 Neptunes. Did the RB-69A use extra radar, ELINT and defensive equipment as follows or different systems at the turn of the 1950s and 1960s?
Radar
AN/APQ-56 SLAR
AN/APQ-24 search radar
AN/APS-23 search radar [uncertain]
Defensive Equipment
AN/APS-54 tail RWR or AN/ALR-12 RWR
AN/ALQ-38 COMINT jammer
AN/ALQ-16 DECM track breaker
AN/ALE-16 Chaff/Flare dispenser
Navigation Equipment
General Precision Laboratories (GPL) PC-210 RADAN Doppler radar navigation, which gave aircraft ground speed and drift; also known as the AN/APN-102. The set was designed to work at altitudes above 300 ft. However, ROCAF tactics from 1959 onward mandated low altitude intrusions into the PRC at max. 150-200 ft. in order for the aircraft to survive radar interception and ground fire. Reportedly, RADAN did not work properly in such circumstances.
AN/ASN-7 navigation computer (replaced RADAN)
Gyrocompass
AN/ARN-6 ADF or newer
AN/APN-22 radar altimeter
AN/APN-70 LORAN
ELINT
AN/APR-13 0.05-1 GHz ESM receiver
AN/APR-9 1-10 GHz receiver or AN/ALR-8 A/J-Band Panoramic ECM Receiver
Ramo-Wooldridge QRC-15A DF receiver
AN/APA-69A 0.1-10.7 GHz DF set
AN/APA-74 pulse analyser
Associated intercepted data recorders
Ramo-Wooldridge System 3 95-145 MHz VHF AM COMINT receiver to intercept enemy airband communications
AN/ALQ-28 Giraffe ELINT Receiver and Granger Associates wide-open receiver and a 10-40 GHz K-band tunable receiver, which replaced the legacy AN/APR-9 and AN/APR-13
Recce
Fairchild Mark IIIA cameras
Comms
AN/ARC-3 VHF radio
AN/ARC-27UHF radio
AN/ARC-38 or Collins 618T HF SSB transceiver
Special mission
Clandestine airdrop dispensers. These planes not only performed recce/ELINT missions but supplied the agents on the ground.
The systems mentioned above are nicely elaborated on Jerry Proc's website at https://jproc.ca/rrp/rrp3/neptune_equipment_details.html
