3M-51 Alfa
anti-ship missile

The P-900 Alfa (or also P-900A Alfa) П-900 3М51 Альфа Alfa AFM-L, GRAU designation 3M51, is an anti-ship missile (with LACM capabilities) developed from the 3M54 Kalibr, P-800 Oniks and P-700 Granit.
The missile has a Granit type engine. It can be operated on new Yasen-class submarine, and can be loaded on ships. Coastal versions of the anti-ship missile are under development. The missile is developed at NPO Mashinostroyeniya.
3M-51 Alfa is also designated as Novator KTRV, Morinform Agat, 3M54, 3M54E and P-900 types.
The new cruise missile was designed for use in the Russian Navy. Modernization of Kirov-class battlecruiser, other new battlecruisers, destroyers and cruisers may include 3M-51 Alfa that can be refitted on ships with existing Zircon, Grom Meteorit, GELA, P1200 Bolid or P-1000 Vulkan missile launchers.
Despite a secrecy surrounding the new missile, it can be presumed that it holds promise as an exportable weapons system.

Why this record matters
“3M-51 Alfa” is worth following because a concise public description often conceals a longer documentary argument. Here, 3M-51, Alfa and anti-ship provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q22906092. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
