According to information published by the Russian Ministry of Defense on its VK social network account on April 9, 2023, Russia has deployed the S-400 air defense missile system in the Donbas region and around the Donetsk People's Republic to enhance protection against aerial attacks, specifically targeting U.S. HIMARS rockets.

Russian units operating S-400 air defense missile systems reliably maintain an "umbrella" over the Donbas region. Every day, in any weather, day and night, and even on their professional holiday, Russian air defense troops are on combat duty. Citing information from the Russian MoD, air defense units have shot down dozens of missiles and shells "intended" for Donetsk and other regions of the DPR (Donetsk People's Republic, including the notorious "HIMARS", guided rockets.

Russian soldiers admit that the rockets fired from the American M142 HIMARS rocket launcher system is a challenging target. Striking a HIMARS guided rocket can be challenging for an air defense system primarily due to their high speed, which makes them difficult to track, intercept, and destroy. Additionally, these rockets have relatively short flight times, which means that air defense systems have a limited window of opportunity to detect, track, and engage the target. Furthermore, guided rockets are designed with the ability to maneuver during their flight, making them harder to predict and intercept by air defense systems.

The S-400 air defense missile system is designed to counter a wide range of aerial threats, including the HIMARS guided rocket. Its combat capabilities against such a target can be attributed to several key features. In general, the system has a maximum engagement range of up to 400 km (248 miles) and can engage targets at various altitudes, from as low as 5 meters (16 feet) to as high as 30 km (18.6 miles).

The S-400 is equipped with a sophisticated radar system capable of detecting, tracking, and engaging targets at long ranges, enhancing its ability to detect and track fast-moving targets like the HIMARS guided rocket.

Moreover, the system can engage multiple targets simultaneously, allowing it to handle potential saturation attacks by multiple HIMARS rockets. Its ability to prioritize and engage multiple threats improves its effectiveness against this type of attack. The S-400 also deploys a variety of interceptor missiles, including some that are capable of reaching very high speeds, enhancing its ability to intercept and destroy fast-moving, maneuverable targets like HIMARS guided rockets.

In addition, the S-400 is designed to engage targets at various altitudes and distances, making it capable of countering HIMARS rockets even if they employ evasive maneuvers or fly at low altitudes. Furthermore, the S-400 is equipped with electronic warfare systems that can counter enemy electronic countermeasures, such as radar jamming and decoys, which helps improve the system's ability to detect, track, and engage HIMARS guided rockets even if they are equipped with countermeasures.

Overall, the S-400's combat capabilities make it a formidable air defense system against HIMARS guided rockets. However, the effectiveness of the S-400 in actual combat scenarios will depend on various factors, including the skill and preparedness of its operators and the tactics employed by both sides.

The High Mobility Artillery Rocket System (HIMARS M142) is an American-made lightweight rocket launcher that can be transported by air or ground and is primarily used by the United States military. It can launch guided and unguided rockets and missiles at a variety of targets, including enemy personnel, vehicles, and structures.

The HIMARS system can launch several types of rockets and missiles, including the Guided Multiple Launch Rocket System (GMLRS) and the Army Tactical Missile System (ATACMS). The GMLRS is a guided rocket that can travel up to 70 kilometers, while the ATACMS is a guided missile that has a range of up to 300 kilometers. HIMARS can also launch other types of rockets and missiles with varying ranges and capabilities, depending on the mission requirements.
