Almaz-Antey Aerospace Defense Concern has more than doubled its production of S-350 and S-400 air defense systems over the past year, according to a statement cited by TASS. Global Demand for the S-400Speculation about new international deals continues to surround the Russian air defense industry. Earlier this month, The National Interest quoted Turkish media reports suggesting that Turkey might negotiate a buyback deal for Russian-produced S-400 systems. However, TASS, citing sources in Turkey’s Ministry of Defense, later denied these claims. Meanwhile, Military Watch Magazine reported in September that India is planning additional purchases of S-400 systems, reinforcing the system’s reputation as one of the most sought-after air defense platforms globally.
