Confidence (i.e., Photo Clarity)
Serial number on engine reads: 52808432202273*
Serial number of unidentified part reads:0930604205069
Also, a microchip in the missile was labeled “03-19” (i.e., March 2019), confirming the missile was manufactured after that date.
An unidentified part was dated “12.2016” (i.e., December 2016), indicating the missile was manufactured no earlier than that.
November 2015 (crashed in Iran during attempted strike in Syria)
Also, the serial number on the engine reads:5280841302201*
Note: “?” indicates the digit was indiscernible or otherwise unavailable.
* For unclear reasons, the serial number on the first engine (from the Kh-101 downed on December 5) comprises 14 digits, whereas the serial number on the second engine (from the Kh-101 downed in November 2015) has 13 digits. It is possible the engine batches became large enough to require a fourth digit. More plausibly, UEC-Saturn may have simply altered how it formats the latter part of the engine’s serial number, as has been known
to happen with other systems.
** For unclear reasons, Russia appears to have jumped back and forth between the 33rd and 34th batches from Q4 2019 to Q3 2020. Perhaps some sort of issue delayed completion of some of the 33rd batch’s missiles until after production of the 34th batch had already begun.
