Russia has offered India the S-350 Vityaz air defence system, proposing it as a complement to existing S-400 batteries. The deal includes technology transfer for potential Indian manufacturing. The S-350, with a range of up to 120 km, can engage multiple targets simultaneously. Russian officials suggest it would enhance India's defense against Pakistan and China. This offer aims to create a denser air defence network, covering medium and inner layers below the S-400's long-range capabilities.
