Russia’s MiG-31Ks with Kinzhal Missiles Use Air Refueling as Ukraine Expands Strike Range

Open-source imagery shared on October 11 highlighted MiG-31 Kinzhal carriers operating far from Ukrainian air defenses, renewing questions about Russian use of Il-78 tankers and longer on-station times before missile launch. If Moscow is routinely refueling these aircraft, it could fire Kinzhals from safer bases and vary attack azimuths and timing, complicating Patriot intercept planning around key cities
On 11 October 2025, a fresh wave of imagery revived the question of whether Russia is keeping its MiG-31 Kinzhal carriers far from Ukrainian threat axes and using aerial refueling to shape optimal launch geometry, as reported by @Osintwarfare on X. The context is a two-year pattern of Ukrainian long-range drone strikes targeting Russian airbases, most notably Engels-2 in December 2022 and Soltsy-2 in August 2023, which has compelled Moscow to reposition its limited inventory of strategic strike platforms deeper into the interior, away from exposed forward bases. This shift reflects both a growing vulnerability to asymmetric attacks and the increasing reach of Ukraine’s improvised deep-strike capabilities. At the same time, U.S. and Ukrainian officials have confirmed Patriot intercepts of Kh-47M2 Kinzhals, giving Russia an operational incentive to vary azimuths, timing and energy at launch. Together, these pressures make tanker support an attractive enabler for standoff Kinzhal employment from safer bases.

The MiG-31K and MiG-31I Foxhound variants were specifically modified to serve as heavy missile carriers, with the Kh-47M2 Kinzhal air-launched ballistic missile integrated onto the centerline station. Open sources describe Kinzhal as an aeroballistic weapon derived from Iskander-M, with a launch weight of around 4,300 kg, an 8-meter length, and a reported reach in the 1,500–2,000 km band depending on carrier and profile. The Foxhound brings very high-altitude, high-speed carriage and a robust airframe; select MiG-31 sub-types have a fixed probe on the port side for Il-78 probe-and-drogue refueling, enabling long on-station times when that hardware is present. This combination yields rapid time-to-target and a heavy conventional or nuclear payload, while retaining the option to recover far from the front.
Operational history and development pathways help explain today’s posture. The Kinzhal entered service in 2017 and was unveiled publicly in 2018; by 2018–2019, Russian statements cited hundreds of training sorties, including refueling events, and an Arctic test launch from Olenya in late 2019. During the full-scale war, Kinzhals have been used repeatedly against Ukraine, yet at least one was publicly confirmed intercepted by a Patriot battery in May 2023. In April 2024, Russian state media reported that the newer MiG-31I standard “received an air refueling system,” signaling intent to normalize tanker support for a portion of the Kinzhal fleet. The cumulative picture is a maturing concept of operations that values range extension, geometry control and basing security.
From a capability standpoint, the Kinzhal’s advantages are speed, mass and compressed engagement timelines when compared with subsonic cruise missiles like Kh-101/Kh-555. Against legacy high-speed anti-ship missiles such as Kh-22/Kh-32, Kinzhal’s air-launch and ballistic profile promise higher energy at impact and greater standoff when paired with a fast, high-altitude carrier. By contrast with U.S. ARRW, which was flight-tested but not fielded, Kinzhal is operational and combat-used, though its performance has proven neither invulnerable nor uniformly decisive in the face of layered defenses. In short, it occupies a niche between classic ALBMs and fast cruise missiles: faster than the latter, less maneuverable than a true hypersonic glide vehicle, and dependent on carrier kinematics and launch geometry for maximum effect.
The strategic implications of air refueling are significant across geopolitical, geostrategic and military dimensions. Geopolitically, tanker-enabled standoff allows Moscow to posture strike sorties from interior regions and the Arctic/Barents or Caspian approaches, while signaling reduced vulnerability to Ukrainian deep strikes, especially salient after multi-base attacks in 2025 demonstrated the reach of Ukrainian drones into Russia’s bomber enterprise. Geostrategically, refueling decouples basing from launch azimuths, letting crews choose bearings that complicate Ukrainian tracking, present different threat axes to Patriot batteries, and compress warning times for targeted infrastructure.
Militarily, Il-78 support expands the Foxhound’s combat radius, preserves fuel for a high-energy climb and dash before release, and increases the probability that a Kinzhal leaves the rail at favorable speed and altitude. The constraint is tanker scarcity and survivability; Russia’s Midas fleet is limited in number and must remain under protected airspace, which in practice means carefully scripted refueling tracks deep inside Russia that still enable the desired launch “basket” toward Ukraine.
The scenario in question involves MiG-31K/I crews refueling over Russian territory, staying beyond Ukraine’s strike range, then accelerating to launch a Kinzhal missile along an optimized trajectory, an approach consistent with Russia’s stated modernization goals, strategic incentives, and the operational dynamics of aeroballistic weapons. For Ukraine and its partners, that means continued emphasis on mobile air defense, rapid cueing against multiple approach bearings, and hardening of critical nodes as Russia seeks to buy flexibility with fuel. For Russia, the payoff is a wider menu of launch corridors at lower basing risk, bought at the price of tanker dependence and the operational reality that Kinzhal has been intercepted and must be employed with greater sophistication to achieve effects.
