Unmanned aerial vehicles (UAVs) have become a prominent part of large military expos in recent years. Russian Army-2020, which took place at the end of August 2020, was not an exception. One of many mockups presented there was introduced as the “loyal wingman”: a development, closely resembling the latest projects by some American, European and Oceanian companies. Let’s take a closer look at it.

The unofficial term “loyal wingman” refers to a small or medium combat drone intended to accompany manned aircraft into battle. Such drones are set to be one of the staple of the coming generation of fighter jets, and an upgrade to the older ones. A number of them are being developed around the world, including Kratos XQ-58 Valkyrie, Sierra 5GAT, Boeing ATS, and several others. 

A swarm of small, fast, cockpitless fighter jets are flying in a tight circle around an F-22 Raptor, reacting to its every move, waiting for a command. They will scout ahead, attack or sacrifice themselves if needed, relying on their superhuman reaction time and precision to execute manoeuvres that human pilots would never manage to do. This is the way many nations envision the air combat of the future. But why?

Russian media often attributed the definition to Sukhoi S-70 Okhotnik, which was shown flying along Su-57 fifth generation fighter jet and was said to be designed to accompany it with ground attack and reconnaissance capabilities. Questions can be raised in regards to such an attribution, as Okhotnik neither is set to have anti-air capabilities, nor to be fully or even partially controlled by an artificial intelligence (AI): two often cited features of “loyal wingmen”.

Therefore, Grom can be considered as either the second or the first Russian attempt at the concept, depending on how you count. Yet there is at least visual basis for attribution this time. The aircraft was publicized as the “Russian answer to Valkyrie”, Kratos drone flight tested in early 2019, and looks quite a bit like one.

The comparison was not avoided neither by Russian media, nor by the manufacturing company Kronshtadt. “The outward similarity to “Valkyrie” is definitely there, but, if you look at the project, the difference becomes obvious. The Russian drone is bigger, but most importantly, it has a much broader spectrum of capabilities,” Nikolai Dolzhenkov, the chief engineer at Kronshtadt, is quoted by Russian news site Utro.ru.

The difference in the size is definitely there. Grom is described as going to have a length of 13.8 meters and a wingspan of 10 meters, as opposed to 8.8 meters and 6.7 meters of the Valkyrie. Grom’s maximum take-off weight is set to be 7 tons (2.5 times that of Valkyrie) and a payload capacity – 2 tons (4 times more than Valkyrie).

As for the “much broader spectrum of capabilities”, Dolzhenkov describes Grom as “shaped to perform missions of a bomber”: breaking through anti-air defenses, attacking ground targets and working in conjunction with other aircraft. Its “fighter-like” functions are supposed to be secondary, “as opposed to Valkyrie”. 

The engineer seems to be referring to Valkyrie’s much-publicized, but never confirmed air-to-air performance, a problem found in almost every journalistic article on the topic. While the intention to arm XQ-58 with air-to-air missiles was never denied and remains a possibility, its primary armament, confirmed by Kratos, remains an assortment of precision-guided bombs. Which puts Grom into the exact same category.
