Verified Strengths
- + Current official Rosoboronexport public data supports one of the broadest published defended-area envelopes in the archive
- + Official export material presents a multi-missile family and radar stack rather than a single-sensor single-missile configuration
- + Benchmark peer system that many professional readers will expect in a serious AMD reference archive
Limitations
- - Public 400 km claims depend on missile and variant scope; current official Rosoboronexport product pages use 380 km as the live system figure
- - Current official public sources reviewed do not support a clean exhaustive operator roll-up
- - Terminal ballistic-missile engagement role is not equivalent to hit-to-kill upper-tier systems such as THAAD or Arrow 3
