11p155

11P155 is a designation used in Soviet and Russian military nomenclature that may refer to more than one object within missile or space-launch programs. In open sources, the exact identity of 11P155 is not consistently documented, and different references assign different meanings to the code. This has produced ambiguity about what the designation covers.

Nomenclature and usage

In the Russian/GRAU indexing system, the 11P prefix is typically associated with launch vehicles or subsystems linked to missile or space-launch programs; the numeric portion differentiates items within a family. Because open literature does not present a single, unified interpretation, 11P155 has been described in some references as a transport and erection facility, while other listings treat it as a development designation for a specific stage or subsystem. The lack of consensus reflects the classified nature of many programs and the variability of naming conventions over time.

Public information and limitations

Publicly available sources offer limited and sometimes conflicting information about 11P155. Details such as the system it belongs to, its exact function, production status, and technical specifications are not reliably established in open reference works. As a result, precise identification typically requires access to authoritative military designation catalogs or declassified program documentation.
