The 1544th Anti-Aircraft Missile Regiment, designated as military unit 55584, is a formation within the Russian Aerospace Forces (VKS). This regiment is tasked with the operation and deployment of advanced surface-to-air missile (SAM) systems, primarily the S-400 'Triumf' and S-300PS platforms. The unit's numerical designation and official status are consistent with Russian military organizational structures, indicating its integration into the broader air defense network.
The headquarters of the 1544th Anti-Aircraft Missile Regiment is situated in the Moscow Oblast region, a strategic area for the defense of the Russian capital and critical national infrastructure. The regiment's deployment is consistent with the layered air defense doctrine employed around Moscow, providing coverage against a spectrum of aerial threats. The proximity to key governmental and military installations underscores the unit's role in the protection of high-value assets.
The regiment's infrastructure includes hardened command posts, missile launch positions, radar arrays, and logistical support facilities. These installations are designed to ensure rapid response, sustained operations, and resilience against electronic warfare or kinetic attacks. The presence of both S-400 and S-300PS systems necessitates specialized maintenance and storage facilities, as well as secure communications infrastructure for integration into the national air defense command network.
The 1544th Regiment is equipped with S-400 'Triumf' and S-300PS surface-to-air missile systems. The S-400 provides enhanced engagement ranges of up to 400 km against aircraft and 60 km against ballistic targets, with advanced radar and missile guidance capabilities. The S-300PS, while an older system, remains effective for medium-range air defense and complements the S-400 by providing additional coverage and redundancy. The combination of these systems allows the regiment to engage a wide array of aerial targets, including aircraft, cruise missiles, and ballistic missiles.
The 1544th Anti-Aircraft Missile Regiment forms a critical component of the Moscow air defense ring, contributing to the multi-layered shield protecting the capital and surrounding regions. The unit is integrated into the wider Aerospace Forces' command and control structure, enabling coordinated responses to airspace incursions. Its operational readiness and advanced equipment enhance Russia's deterrence posture and provide a rapid reaction capability against both conventional and emerging aerial threats.
Recent years have seen continued modernization of the regiment's equipment and operational procedures, with the full transition to S-400 systems either completed or in advanced stages as of 2024. Training cycles have been intensified to maintain crew proficiency with both legacy and next-generation systems. The regiment has participated in national and regional air defense exercises, demonstrating interoperability with other air defense assets and contributing to the overall effectiveness of Russia's integrated air defense system.
