After 25 years of operation, all missiles of the Buk systems are subject to decommissioning and disposal.The maximum lifetime of the missile, the engine from which was demonstrated to us [by the Dutch-led JIT] was 2011 (1986 + 25), after which it should be decommissioned and sent for disposal.
Disinformation refers to Russian Ministry of Defence statement on May 25 that "after 25 years of operation, all missiles of the Buk systems are subject to decommissioning and disposal". www.interfax.ru/russia/614297
In fact, the Buk manufacturer Almaz Antey used one missile from 1987 in their #MH17 test in 2015, which means it was 28 years old and should have already been decommissioned. twitter.com/EliotHiggins/status/1003904308755214336
