Can our experts help to compile a list of avionics of the U-2C #56-6693 (item 360), which was shot down on 1 May 1960 in the USSR please? I am trying to ascertain from old manuals what kind of COM, NAV and other systems could have been used. Can our experts provide hints on the subject please?
COM:
C-823/AIC-10 audio
AN/ARC-34 UHF AM
Commercial ARC Type 12 VHF AM or military AN/ARC-3 VHF AM
Collins KWM-1 HF SSB, 14-30 MHz range, 1 preset, ca. 100W RF
Perhaps the plane was equipped with the AN/ARA-26 keyer, which could key HF radio in emergency.
Apparently early U-2s had no IFF unless the Wilcox 914-1 commercial transponder was used.
NAV:
MA-1 gyro compass
AN/ARN-6 ADF or AN/ARN-44 ADF
AN/APQ-56 SLAR radar mapping installed on some a/c
RADAN PC-210A Doppler radar nav on some a/c, used in conjunction with the AN/APQ-56
or RADAN PC-204A + AN/ASN-6 nav computer
Lear 5105A autopilot
Could it have used the TACAN like the AN/ARN-21?
Other equipment:
Perkin-Elmer Mark I Driftsight, PE-151-0001 or Mark II, or Mark III
Tracker Camera
A-1 Camera
A-2 Camera
B Config. Camera
System I, II or IV FERRET ELINT
System IX ECM designed for the P2V and U-2. Used the S-441 Deception Repeater (Granger Model 504). The set was to provide false angle information to X-Band conical scan airborne intercept radars and used inverse gain technique. Powers referred to it as "the Granger box."
Wikipedia has some old Russian photos of the debris at

This one shows the "Granger Box" 10A fuse:
This one apparently the ELINT equipment:
And this one apparently the data recorder:
