The US and its allies are belatedly ramping up their weapons support to Ukraine as invading Russian forces lavatory down in opposition to shocking resistance and winter mud. Russian air superiority may cease these arms and ammunition shipments any day now, however the US navy may do extra to assist Ukrainian troops with out unduly escalating the battle.
Political leaders and analysts have been proposing operations like no-fly zones or strikes in opposition to Russian armored columns to assist Ukrainian forces cease Russia’s advance. Whereas rhetorically satisfying, these operations may present President Vladimir Putin precisely the excuse he wants for Russia’s lackluster efficiency to this point and assist him set up a story of America because the aggressor that will prop up help at house.
As a substitute, the US navy ought to get entangled within the battle in methods which can be reversible, deniable or peripheral. Digital warfare was one of many US navy’s uneven benefits within the Chilly Conflict and will gradual or confuse Russian forces utilizing reversible results and with out inflicting direct casualties.


US Military MQ-1 Grey Eagle UAVs and Air Pressure or Marine Corps MQ-9 Reapers may fly from Romania or Poland into Ukrainian airspace to disrupt Russian communications utilizing jammers, such because the Marine Corps Intrepid Tiger digital assault pods. These methods may be employed in opposition to Russian naval forces on the Black Sea to degrade their potential to coordinate amphibious operations alongside the Ukrainian coast west of Crimea.
Probably the most intense type of digital assault is high-power microwave, which damages electronics corresponding to navigation methods, radios and sensors. Russian columns approaching Ukrainian cities might be attacked by high-power microwave, leaving automobiles stranded and susceptible to Ukrainian ambushes.
The US ought to ship UAVs just like the MQ-9 Reaper or expendable goal drones such because the RQ-58 Valkyrie into Ukrainian airspace carrying high-power microwave payloads like that on the Air Pressure CHAMP missile to assault Russian digital methods. As a result of microwave assaults don't depart seen injury, they might be denied — however Russian navy leaders would perceive what occurred.

Like digital warfare, cyber operations corresponding to denial-of-service assaults can create non permanent disruptions. Like high-power microwave, cyber may also create everlasting injury. The US and Russia have avoided cyberattacks on civilian targets, however they might be employed extra aggressively in opposition to Russian navy forces.
Russian logistics are already not maintaining with its maneuver models, slowing the Russian advance. The US ought to additional degrade Russian troops’ help by disrupting the pc networks used to handle provide inventories and actions from depots. These networks are unlikely to be as well-protected as Russian operational networks, and hitting them wouldn't be as escalatory as attacking Russian command and management instantly.
Peripheral operations may assist Ukrainian forces by constraining Russian choices and dissuading growth of the combat. Earlier than the invasion, US Navy ships exited the Black Sea, and now Russian warships have established maritime superiority alongside the coast of Ukraine. Nonetheless, NATO allies Turkey, Romania and Bulgaria additionally border the Black Sea; the US ought to step up its posture there because it did in Poland and the Baltics to the north.


Turkey lower off entry to the Black Sea this week, however when entry is restored the US Navy ought to return to guard NATO allies and freedom of navigation within the Black Sea’s worldwide waters. Within the meantime, US Navy ships ought to again up Turkey in stopping Russian ships’ passage into the Black Sea and help the navies of NATO allies utilizing US P-8A Poseidon maritime patrol plane and MQ-4C Triton UAVs working from Romania or Bulgaria.
The US has a chance to assist Ukrainian freedom fighters construct on their early success and, let’s hope, finish the Russian invasion. Extra vital, if the US navy doesn't present resolve and persistently interact the Russian navy at low ranges of escalation like these, it could lose credibility as a defender of different US allies or companions. Taiwan and Japan, for instance, already face gray-zone aggression from China, which may escalate if Beijing is inspired by Russia’s expertise in Ukraine.
US Cyber Command is discovering success in its confrontations with dangerous actors on the Web utilizing the persistent-engagement strategy. The US ought to apply it extra broadly to discourage adversaries corresponding to Russia and China.
