  1. Check here: https://www.avialogs.com/reader.php?jid=56432#p=1
  2. Could someone share the pages from the original flight manuals that list and elaborate the C-123B and K avionics suite please?
  3. The high altitude was not the only defense. The documentation on the 1960 U-2 incident mentioned that Powers' U-2 was fitted with the Granger box. It was a jammer to be used against the S-75 radar. Whether it was powered on while over Sverdlovsk remains unattested. Apart from the cameras, Powers' U-2 also carried a SIGINT package to monitor and record Soviet radars signals. The Soviets used the remains of these systems as the evidence against Powers in the court. These items were particularly incriminating. Wiki picture with the Granger box circuit breaker field.
  4. Well, could the U-2 operate effectively at night in the photo recce mode? Would an IR photo be sharp enough to provide any meaningful intelligence? Obviously I am not taking into consideration the SIGINT payload that the plane could carry, as well.
  5. Thank you very much indeed for the explanation.
  6. Thank you very much for the explanation. Could this blue paint have any significant impact on the real-life aircraft performance, eg. the reduction of U-2's speed?
  7. Awesome picture. Thank you for sharing! By the way, why was the nose of the plane painted black? It seems that on a number of natural metal early U-2s the nose also had the color of metal, but only some early a/c eg. the 66701 had a black nose. Did the black nose occur on the a/c with the System I or III SIGINT equipment only?
  8. Thank you for the reply and the details on the paint. Do you happen to know the rationale behind painting the natural metal U-2s semi-gloss Sea Blue FS 25044? That would actually make these birds more visible.
  9. I'd like to inquire about the true colors of the early U-2, including the one shot down in 1960 in the USSR. The remains of that plane are stored in a Moscow museum as depicted on a wiki picture below. My question is: what was the original blueish color, and what was the yellowish tone? I presume the latter was some sort of primer or aluminum cover to prevent corrosion.
  10. Do you happen to remember the radio set as used on the CH-113? Meanwhile I established that it was made by the Canadian Marconi Company (CMC). The manufacturer unfortunately was not able to help as far as the nomenclature and specs of the radio are concerned. I presume that the radio supported AM (voice) and CW (telegraphy), and not SSB (single sideband voice).
  11. Do you happen to know the type of the High Frequency radio set used on the early CH-113s? Below is a sketch from the manual from the 1960s. While other avionics pieces can be easily identified, the HF radio remains a mystery. Notably, the control panel has separate knobs to choose one from ten transmitter and ten receiver preset frequencies.
