Russia has introduced a new cruise missile in the with a clear idea behind: reduce costs and launch more units to saturate the air defenses. This is the S-71K “Kovyor”a weapon that marks a and that, according to Ukrainian intelligence, relies heavily on electronic components manufactured outside Russia, including Western countries.
The analysis released by the Ukrainian military intelligence (HUR) shows a less sophisticated system than , but designed to fulfill a specific function: overcome defense systems not by quality, but by quantity.
A simpler missile… and more dangerous by volume
The S-71K is not intended to compete with high-end missiles such as the Kh-101 or Kalibr. Your logic is different. The military expert Andrii Kharuk explains it: “Traditional cruise missiles are expensive. “What we see now are simpler, cheaper models that can be launched in greater numbers.”
This change has direct implications on the battlefield. A cheaper missile allows you to produce more units, launch massive attacks and force the enemy to spend expensive defensive resources. This is what is known in military terms as a saturation strategy.
Between a drone and a cruise missile
The design of the S-71K falls somewhere in between. It is not a drone like the Shahed, but neither is it a high-precision missile latest generation. It’s a mix:
- navigation system inertial relatively simple.
- flight controller basic.
- Structure of composite materials and aluminum.
- Range estimated up to 300 kilometers.
The result is a less sophisticated, but functional and replicable weapon. According to Kharuk, these types of systems “They act as a bridge between drones and cruise missiles”combining reduced cost and greater impact capacity than drones.
The objective: saturate the Ukrainian defenses
The problem is not just the missile itself. It is the accumulated effect. Air defense systems work best when they can intercept limited targets. But when the number of threats increases, the equation changes.
Each interceptor costs money. And in many cases, intercepting a cheap missile requires a much more expensive defensive missile. There is the key to the S-71K: it doesn’t need to be perfect, it just needs to be sufficient… and arrive in numbers.
Western chips in Russian weapons
One of the most striking aspects of the analysis is the origin of its components. According to Ukrainian intelligence, most of the missile’s electronic systems came from outside Russia, including USA, Germany, Switzerland, Japan, Taiwan and Ireland.
It is not an isolated case. Since the start of the war, various investigations have detected Western microchips in Russian weapons, despite international sanctions. The explanation lies in global supply chains.
How the components arrive despite the sanctions
Export restrictions have failed to completely shut down the flow of technology. Components arrive in Russia through intermediary countriesfront companies, re-exports from civil markets and international logistics centers.
Many of these products are dual-use: they serve both civil and military applications. That complicates its control. The Ukrainian authorities have sanctioned networks and companies involved in this process, but the system continues to function with some effectiveness.
Integration with fighters and drones
The S-71K was designed to operate with the Sukhoi Su-57 fifth-generation fighteralthough its use could be extended to more common platforms such as the Su-34.
Its integration with the Sukhoi S-70 Okhotnik combat drone is also being studied, which would expand its operational possibilities. This reinforces its versatile character: a weapon adaptable to different launch systems.
Despite its advantages, the S-71K has a major bottleneck: the engine. The missile uses an R500 turbojet, a component that Russia has historically had difficulty producing on a large scale.
Kharuk points to this as the main factor that may limit its massive deployment. Without enough drivers, the saturation strategy loses steam.
A silent change in war
The S-71K is not the most advanced missile in the Russian arsenal. But it may be one of the most relevant, because it reflects a change in focus: less dependence on complex systemsmore emphasis on mass production and intensive use of commercial components.
It is an adaptation to the reality of prolonged war, where economic and logistical wear and tear matters as much as technology. Ultimately, the conflict is also fought in economic terms.
A cheap missile that forces expensive resources to be spent on defense creates an indirect advantage. And if it can also be manufactured with components accessible in the global market, that advantage is multiplied. That is why the S-71K is not just a weapon. It’s a symptom.
