The trials of new 40N6 surface-to-air missiles for Russia’s S-400 Triumf air defence system have entered the final stage and are expected to be handed over to Russian armed forces for a test operation in summer. The launch trials of 40N6 were held in February and the missile received only minor design changes. Another series of trials are scheduled in April-May after which the final decision on serial production is expected.
