The Ukrainian Ministry of Defense\u2019s Main Directorate of Intelligence (GUR) released on April 28 more details of Russia\u2019s S-71K \u201cKovyor\u201d stealth air-launched cruise missile that has been reportedly in use since last year.<\/strong><\/p>\n\n\n\n

In the past, it was reported by the intelligence service and other sources that the missile was specifically designed for the Sukhoi Su-57 stealth fighter jet.<\/p>\n\n\n\n

The GUR claimed in its latest report that the S-71K was developed by Russia\u2019s United Aircraft Corporation\u2019s (UAC). It also revealed that the warhead of the missile utilizes a Soviet-era 250-kilogram OFAB-250-270 high-explosive fragmentation bomb.<\/p>\n\n\n\n

The missile design features a low-observable airframe with a trapezoidal cross section, chined nose, pop-out swept wings, and an inverted V-tail.<\/p>\n\n\n\n

It is made from \u201ca multi-layer fiberglass material with additional reinforcement,\u201d according to the intelligence report, which notes that other internal elements are made of aluminum alloys.<\/p>\n\n\n\n

The S-71K is powered by a compact R500 turbojet engine, also made by UAC, and features what the GUR describes as \u201can inertial navigation system based on simple sensors.\u201d The engine is fed air through a top-mounted conformal intake with a pentagon-shaped intake duct. It is also linked to three separate internal fuel tanks.<\/p>\n\n\n\n

The intelligence agency assessed that the S-71K has an operational range of up to 300 kilometers. Earlier reports suggest that the missile flies at a speed of Mach 0.6 and at altitudes of up to 27,000 feet.<\/p>\n\n\n\n

Reports from 2024 also suggest that Sukhoi \u2014 a part of UAC \u2014 had received approval from the Russian Defense Ministry to begin producing the S-71K, after it underwent \u201csignificant design changes\u201d based on lessons from the special military operation in Ukraine.<\/p>\n\n\n\n

Photos of a Su-57 carrying test models of the missiles at the Russian flight research center in Zhukovsky even emerged online that year.<\/p>\n\n\n\n

Besides the Su-57, It is also expected that the S-71K could be integrated with the S-70 stealth combat drone, also developed by Sukhoi.<\/p>\n\n\n\n

It is also known that another version of the missile, the S-71M \u201cMonokhrom\u201c, is under development by UAC. This version has a \u201cm-in-the-loop\u201d capability, to allow dynamic targeting, including against moving targets. For that, it likely features some sort of terminal optical guidance.<\/p>\n\n\n\n

The S-71K was apparently developed to specifically provide cost-effective, low-observably stand-off strike capabilities for the Su-57.<\/p>\n\n\n\n

Based on the fact that the Russian MoD approved the mass production of the missile and is developing a second more advanced version, it can be assumed that its real combat tests in the special military operation zone were extremely successful.<\/p>\n","protected":false},"excerpt":{"rendered":"
