I thought I would post more of the information that I understand about who has what version of which BUK missile and warheads.
There is a lot of conflicting information on the internet about different versions of BUK missile systems, and their key components. It is obvious that some of it has to be wrong (for example many sources do not properly identify that the original BUK missile system had a different warhead; which is relatively easy to identify by other sources discussing the early 1970's version of the BUK, and changes over the decades (I have seen two different sources listing 3 generations of warheads for the BUK system since the early 1970's).
The information I have seen says that Ukraine was originally supplied with the BK-37 BUK System that contained a 9M38 missile with a 9N310 warhead. That would have made a lot of sense as the Soviet Union shifted older weapon systems from Russia and countries directly facing Germany and other parts of Europe to countries with lessor direct threats.
The same information says that Ukraine later received some BK-37M (BUK-M1) Systems that contained a 9M38 missile with a 9N314 warhead. The information is sketchy on how many BK-37M's (BUK-M1) were supplied to Ukraine.
The Dutch Safety Board identified the shrapnel specifically to a 9N314M warhead; which was installed on the 9M38M1 missile (and possibly the 9M317 missile which is not under discussion here).
The BUK-M1 System is capable of firing both the 9M38 and 9M38M1 missile.
The information I have seen says that a 9M38M1 missile could be fabricated using major components from a 9M38 missile; and that the Soviet Union did that (the US has also created newer versions of missiles from older missiles). Thus, a 9M38M1 missile could realistically have an older 9M38 rocket engine.
I have seen information that suggest that it would be possible to put older warheads on the 9M38M1 missile; and the same information asked the question of why anyone would do that.
As I mentioned in one of my post above. It is my understanding that Ukraine allowed inspection of its BUKs to validate that they had the older warheads.
Recent news is an announcement by Russia the Ukraine has not received any new BUK missiles since 1991. http://tass.com/world/1006378
This supports the concept that Ukraine does not have the modern warhead as the 9M38M1 missile appears to date from no sooner than 1986 and the Soviet Union would have been putting it in more critical areas than Ukraine; and shifting older weapons to Ukraine (I think it unlikely that Ukraine would have received the most modern missiles in the first 5 years of production).
Below is a link to the Dutch Safety Board Report and the warhead identification.https://www.onderzoeksraad.nl/uploads/p ... 959FE4ECBC
So the real information is still that it was a 9N314M warhead; only known to have been installed on the 9M38M1 missile; and to the best of my information - not a warhead installed on any Ukraine BUKs.
I hope this helps,
