On September 26, 2017, modernised Tupolev Tu-95MS bombers of the Russian Aerospace Forces (VKS) Long-Range Aviation Command executed another strike with Kh-101 air-launched cruise missiles (ALCMs) against targets in Syria. According to Russia’s Defense Ministry, the missiles targeted ISIS and Jabhat al-Nusra ‘command posts, hardware and manpower concentration areas as well as ammunition depot.’ As with previous Russian ALCM strikes during the conflict, the heavily publicised September 2017 strike was intended to serve yet another reminder to the United States and NATO (as well as to other potential adversaries) of the Russian Aerospace Forces’ growing long-range precision-strike capabilities.
Designed by MKB Raduga, the Kh-101 is an advanced conventionally-armed cruise missile with low observable characteristics. The missile has a reported operational range of 4,500km (2,800 miles), and features a guidance package that includes an inertial navigation system (INS), a terrain contour matching (TERCOM) system, a digital scene-matching area correlation (DSMAC) system, and a GPS/GLONASS receiver. Compared with the older, conventionally-armed Kh-555 ALCM, the Kh-101 features significantly improved accuracy and a larger payload, making it suitable for use against hardened targets. Drone footage of Kh-101 strikes from Syria, including the September 2017 strike, appears to attest to the missile’s high-accuracy (though the impact of only several missiles is shown).
Russian bombers first utilised Kh-101s in combat on 17 November 2015, when Tu-160 bombers delivered the new cruise missiles against targets in Syria. The strike, which also included Tu-95MS bombers armed with older Kh-555 ALCMs, marked the combat debut of both the Kh-555 and Kh-101 as well as the Tu-160 and Tu-95MS. Exactly one year later, on November 17, 2016, modernised Tu-95MS bombers executed their first strike with Kh-101 cruise missiles. Before the integration of the Kh-555 and Kh-101 on the Tu-95MS and the Tu-160, and their subsequent employment in Syria, the two bombers were utilised solely for the nuclear deterrence role and did not participate in conventional conflicts.
The only Russian bomber currently in service with the Long-Range Aviation Command to have seen combat before Syria is the Tu-22M3, which flew sorties in the Soviet-Afghan War, the First Chechen War and, more recently, the 2008 Five Day War with Georgia. In all three conflicts, the Tu-22M3 was used exclusively for delivering unguided (or ‘dumb’) bombs – a mission which it continues to fulfil in Syria. Given that bombers delivering unguided munitions are likely to find themselves within range of enemy fighter aircraft and surface-to-air missiles (SAMs), such an approach is only viable for low-intensity conflicts in which the adversary lacks credible air defences. Even then, multiple sorties against a single target may be required, and excessive collateral damage may be caused due to the poor accuracy of unguided bombs. Russia witnessed the difficulty of operating its bombers in a contested airspace first hand in August 2008, when one of its Tu-22M3s was shot down by a Georgian SAM during a strike sortie against a Georgian military base.
The introduction of the Kh-555 and Kh-101, therefore, represents a crucial new capability for Russia’s Long-Range Aviation Command, one which allows it to partially compensate for the lack of a long-range very low observable platform. Unlike the USAF, which operates the B-2A stealth bomber, the VKS does not currently field a long-range very low observable platform capable of penetrating modern integrated air defence systems (IADS) and won’t be fielding one until at least the end of the next decade. Hence, to avoid being targeted by adversary fighter aircraft and ground-based air defences in the event of a conflict, Russian bombers will need to launch long-range conventionally-armed ALCMs from stand-off ranges. This is particularly true for the cumbersome turboprop-powered Tu-95MS – the backbone of Russia’s Long-Range Aviation Command, – which, unlike the Tu-160 and Tu-22M3, is not capable of operating at supersonic speeds.
In this regard, the integration of the Kh-101 on the Tu-95MS dramatically expands the legacy bomber’s conventional strike capability, which until recently, was limited to dropping unguided bombs, transforming it into a formidable long-range precision-strike platform capable of accurately engaging hardened targets in heavily defended areas. At present, Russia is also outfitting its Tu-95MS bombers with SVP systems (developed by ZAO Gefest i T), which will enable Russian bomber crews to retarget their missiles before launch. This will further enhance mission flexibility, allowing modernised Tu-95MS bombers to strike not only fixed but also relocatable targets. The ability of the Kh-101 to cover very large distances also reduces the Tu-95MS (and Tu-160’s) need to rely on in-flight refuelling for long distance missions. This, as several analysts have noted, makes the Kh-101 a particularly valuable asset given Russia’s relatively small fleet of aerial-refuelling tankers and limited overseas basing options. A modernised Tu-95MS can carry up to eight Kh-101 ALCMs on four externally-mounted two-station pylons, while a Tu-160 can carry up to 12 such missiles on two internally-mounted six-station rotary launchers.
Considering that neither ISIS, nor the other factions with whom Russia is presently engaged in active combat with field capable air defenses, the Long-Range Aviation Command’s use of modernized Tu-95MS and Tu-160 bombers with Kh-101 ALCMs in Syria stems from Moscow’s desire to test both the reliability of its new air-launched weapon and its carrier platforms as well as the proficiency of Russian bomber crews under real combat conditions. As with the occasional use of conventionally-armed Kalibr sea-launched cruise missiles (SLCMs) in the Syrian conflict, the employment of Kh-101s is likewise intended to convey a strong signal to Russia’s potential adversaries and reflects Moscow’s desire to place greater emphasis on conventional deterrence. The need to expand precision-strike capabilities and increase reliance on conventional weapons for deterrence has been highlighted in Russia’s 2014 Military Doctrine and has been voiced by Russian military officials. As Russian Defense Minister, Sergei Shoigu, noted in February 2017, though:
[t]he development of strategic nuclear forces remains an absolute priority for us […] the role of nuclear weapons in deterring a potential aggressor will decrease first of all due to development of high-precision weapons.’
For the United States and NATO, Russia’s growing emphasis on conventional long-range precision-strike weapons such as the Kh-101 represents an increasingly pressing need to bolster missile defences.
