Assessing the Russian-warship theory of MH370

Does reliable evidence support the claim that a Russian warship or submarine destroyed MH370?

No reliable support was identified in the research described here. The proposed Russian attack remains an unsubstantiated allegation.

A commenter proposes that the cruiser Varyag, an S-300-family weapon, or a Kilo-class submarine could explain MH370's disappearance. These are allegations requiring corroboration. Clarke had found no supporting source he considered reliable in his research into the case. His interest included the search effort, which used ships his father had helped create. He also identifies a risk of bias among acquaintances inclined to seek Russian culpability. The conclusion is limited to the material he had examined: an imaginable scenario does not establish that the attack occurred.
