When delivered, "Vikramaditya" had yet to be fitted with any on-board armament, leaving her dependent on her battle group for self-defence. This was rectified during the ship's short refit of April–June 2015, when she was fitted with four license-built AK-630 CIWS, and a Barak 1 SAM system stripped from the decommissioned . During the ship's first scheduled major refit in 2017, the Barak 1 system will be replaced with the newly developed Barak 8 long-range air-defence system (LR-SAM), which is currently being tested. It is launched from vertical launch cells, and has an operational range of 0.5–100 km The carrier will carry up to 48 missiles.
