Evidence & current status
An announced design or exhibition concept. The reviewed evidence does not establish a flying prototype or operational deployment.
Role & programme
A proposed jet combat-aircraft and collaborative-autonomy concept. It is distinct from the unrelated small Grom multirotor.
GUR identifies the Kronshtadt programme, while CSIS’s 2026 research discusses its earlier command-and-control concept. The reviewed sources do not establish a flying prototype or operational delivery. Conceptual mission roles are therefore not displayed as fielded capabilities. The similarly named small Grom in another GUR record has different manufacturer and performance data.
