War in Ukraine: What Are Tactical Nuclear Weapons? An International Security Expert Explains

Tactical by the numbers
Tactical nuclear weapons, which are in some cases called battleground or nonstrategic nuclear weapons, were designed to be utilized on the battlefield– for example, to counter overwhelming conventional forces like large formations of infantry and armor. They are smaller sized than strategic nuclear weapons like the warheads brought on global ballistic missiles (ICBMs).
While professionals disagree about exact definitions of tactical nuclear weapons, commonly determined attributes consist of lower explosive yields, determined in kilotons, and shorter-range shipment vehicles. Tactical nuclear weapons vary in yields from portions of 1 kiloton to about 50 kilotons.
For recommendation, the atomic bomb dropped on Hiroshima was 15 kilotons. This suggests that some tactical nuclear weapons are capable of causing extensive destruction. The largest standard bomb, the Mother of All Bombs or MOAB, that the U.S. has actually dropped has an 11-ton (0.011-kiloton) yield.
Shipment systems for tactical nuclear weapons also tend to have shorter ranges, usually under 310 miles (500 kilometers) compared to tactical nuclear weapons, which are typically created to cross continents.
Since low-yield nuclear weapons explosive force is not much higher than that of progressively effective standard weapons, the U.S. military has decreased its dependence on them. Pakistan, China, India, Israel, and North Korea all have several types of tactical nuclear weapons.
Russia has retained more tactical nuclear weapons, approximated to be around 2,000, and relied more heavily on them in its nuclear method than the U.S. has, mainly due to Russias less sophisticated standard weapons and abilities.
Russias tactical nuclear weapons can be released by ships, aircrafts, and ground forces. Most are deployed on air-to-surface rockets, short-range ballistic missiles, gravity bombs and depth charges delivered by tactical and medium-range bombers, or naval anti-ship and anti-submarine torpedoes. These missiles are mostly held in reserve in central depots in Russia.
Russia has upgraded its delivery systems to be able to bring either nuclear or traditional bombs. There is heightened issue over these dual capability delivery systems because Russia has actually used a lot of these short-range rocket systems, especially the Iskander-M, to bombard Ukraine.
Russias Iskander-M mobile short-range ballistic rocket can bring standard or nuclear warheads. Russia has actually utilized the missile with standard warheads in the war in Ukraine.
Tactical nuclear weapons are considerably more damaging than their conventional counterparts even at the same explosive energy. Nuclear surges are more effective by factors of 10 million to 100 million than chemical explosions, and leave deadly radiation fallout that would pollute air, soil, food and water supplies, similar to the disastrous Chernobyl atomic power plant disaster in 1986. The interactive simulation site NUKEMAP by Alex Wellerstein illustrates the multiple effects of nuclear surges at different yields.
Can any nuke be tactical?
Unlike tactical nuclear weapons, tactical weapons are not focused on mutually assured destruction through frustrating retaliation or nuclear umbrella deterrence to safeguard allies. While tactical nuclear weapons have not been consisted of in arms control contracts, medium-range weapons were consisted of in the now-defunct Intermediate-range Nuclear Forces treaty (1987-2018), which lowered nuclear weapons in Europe.
Both the U.S. and Russia decreased their total nuclear arsenals from about 19,000 and 35,000 respectively at the end of the Cold War to about 3,700 and 4,480 since January 2022. Russias hesitation to work out over its nonstrategic nuclear weapons has stymied further nuclear arms manage efforts.
The essential question is whether tactical nuclear weapons are more “useable” and therefore might possibly set off a full-blown nuclear war. Their development was part of an effort to overcome concerns that because large-scale nuclear attacks were widely viewed as unthinkable, strategic nuclear weapons were losing their worth as a deterrent to war in between the superpowers. The nuclear powers would be most likely to use tactical nuclear weapons, in theory, and so the weapons would strengthen a nations nuclear deterrence.
Any usage of tactical nuclear weapons would conjure up defensive nuclear methods. Then-Secretary of Defense James Mattis especially mentioned in 2018: “I do not think there is any such thing as a tactical nuclear weapon. Any nuclear weapon utilize any time is a strategic game changer.”
This documentary explores how the risk of nuclear war has changed– and perhaps increased– given that the end of the Cold War.
The U.S. has slammed Russias nuclear technique of intensify to de-escalate, in which tactical nuclear weapons could be used to hinder a widening of the war to include NATO.
While there is argument amongst experts, Russian and U.S. nuclear strategies concentrate on deterrence, therefore involve large-scale vindictive nuclear attacks in the face of any first-nuclear weapon usage. This implies that Russias danger to use nuclear weapons as a deterrent to standard war is threatening an action that would, under nuclear warfare doctrine, welcome a retaliatory nuclear strike if intended at the U.S. or NATO.
Nukes and Ukraine
I think Russian use of tactical nuclear weapons in Ukraine would not accomplish any military objective. It would pollute the area that Russia declares as part of its historical empire and potentially drift into Russia itself. It would increase the probability of direct NATO intervention and ruin Russias image worldwide.
Putin aims to prevent Ukraines continued successes in gaining back area by preemptively annexing regions in the east of the nation after holding staged referendums. He might then state that Russia would utilize nuclear weapons to defend the new area as though the existence of the Russian state were threatened. I think this claim extends Russias nuclear method beyond belief.
Putin has clearly declared that his danger to use tactical nuclear weapons is not a bluff specifically because, from a tactical perspective, utilizing them is not trustworthy.

Nuclear explosions are more effective by factors of 10 million to 100 million than chemical explosions, and leave deadly radiation fallout that would pollute air, food, water and soil products, comparable to the disastrous Chernobyl nuclear reactor meltdown in 1986. The essential concern is whether tactical nuclear weapons are more “useable” and for that reason might possibly trigger a full-scale nuclear war. Their advancement was part of an effort to get rid of concerns that because massive nuclear attacks were commonly seen as unthinkable, strategic nuclear weapons were losing their worth as a deterrent to war in between the superpowers. The nuclear powers would be more most likely to utilize tactical nuclear weapons, in theory, and so the weapons would boost a countrys nuclear deterrence.
Any use of tactical nuclear weapons would invoke defensive nuclear methods.

Illustration of a nuclear weapon blast.
As Russia has actually suffered unanticipated battleground losses in eastern Ukraine, Tactical nuclear weapons have burst onto the global phase. Russian President Vladimir Putin threatened that Russia will “utilize all weapon systems readily available to us” if Russias territorial integrity is threatened. Putin has actually defined the war in Ukraine as an existential battle versus the West, which he stated desires to weaken, divide, and ruin Russia.
U.S. President Joe Biden slammed Putins obvious nuclear threats against Europe. On The Other Hand, NATO Secretary-General Jens Stoltenberg minimized the threat, saying Putin “understands very well that a nuclear war needs to never ever be combated and can not be won.” This is not the very first time Putin has actually conjured up nuclear weapons in an effort to prevent NATO.
I am an international security scholar who has worked on and researched nuclear restraint, nonproliferation, and costly signaling theory used to worldwide relations for twenty years. Russias big toolbox of tactical nuclear weapons, which are not governed by global treaties, and Putins teaching of threatening their use have raised tensions, but tactical nuclear weapons are not just another kind of battlefield weapon.
