The Chinese developers test nuclear cluster bombs.

Cluster bombs are weapons that consist of a single large canister bomb, delivering a large number of small submunitions. Those may be hand grenade-sized bomblets. These were released from a 500-1000 kg bomb. It can cover a large area. Those bombs are effective against a large concentration of forces. Those weapons are sometimes banned. Because all those bomblets have exploded. And that causes injuries to the civilian population. 

Nuclear cluster bombs are similar to conventional cluster bombs. But those submunitions use thermonuclear warheads. There is a possibility that three high-power nuclear warheads will  cause much more destruction than one or two warheads. But another threat is the case that small-sized, low-yield nuclear weapons like neutron warheads will be delivered into a large area. Those nuclear bomblets can affect a large area. The neutron-bomb-based cluster bombs are tools that can destroy large targets. The biggest problem with neutron bombs is that they are very small. 

Those neutron bombs, officially called Enhanced Radiation Weapons (ERW), can cover a large land area. Those neutron bomb clusters can be dropped from the bomber, or the Intercontinental Ballistic Missiles, ICBM, can carry them. The thing is that those small nuclear devices don’t need a very powerful rocket. And things like drones can carry them to the target. 

Those ICBM-launched neutron bomb clusters are hard targets for air defense. The neutron bomb carrier can be a similar cluster deliverer. That is used in regular cluster bombs.  When an ICBM enters the atmosphere, that system starts to spin and deliver neutron bombs. Or the neutron bombs can deliver from above the atmosphere. In some scenarios, the neutron bomb attack predicts full-scale nuclear attacks.

Above: Davy Crockett, W-54 nuclear device. Drones can carry those warheads very well. And if they are in the drones. Like Geran 3 or Shahed, they can cause very big destruction. All nuclear devices are similar. And that means those small nuclear devices can look the same. Those small nukes can be installed in Geran 3-type drones.  

Geran 3 Drone. 

Drones can also carry Special Atomic Demolition Munitions, SADM’s. Called “suitcase nukes,” they are man-portable nuclear devices. They are really dangerous. They are not very large systems. The weight of the 1950s systems is about 30-50kg. 

Wikipedia tells about the SADM development like this: 

“The Special Atomic Demolition Munition (SADM), also known as the XM129 and XM159 Atomic Demolition Charges,[1] and the B54 bomb was a nuclear man-portable atomic demolition munition (ADM) system fielded by the US military from the 1960s to 1980s but never used in combat. It had an estimated yield of up to 1 kiloton of TNT.” (Wikipedia, Special Atomic Demolition Munition)

“At the time of the weapon's development, the existing Atomic Demolition Munition (ADM) was the T-4 Atomic Demolition Munition. Its transport required 4 men, each carrying a 40-pound (18 kg) section. The development began in June 1960, and an interim Mark 54 Mod 0 (now called the B54-0) weapon was put into production in April 1963. Production of the B54 Mod 1 SADM began in August 1964. The weapon was 12 inches (305 mm) in diameter, 18 inches (457 mm) long, and weighed 58.5 pounds (26.5 kg). It included the warhead, a fuze, and a firing system with a mechanical timer, a ferroelectric firing set, and a sealed housing. The body was constructed with aluminum forgings and molded fiberglass, and foam-rubber insulation was used between the warhead and case. Dials were illuminated with tritium-phosphor paint for easy night-reading. A housing for underwater emplacement was provided that included external controls.” (Wikipedia, Special Atomic Demolition Munition)

“The B54 Mod 2 started production in June 1965. The weapon was the same size as previous mods but now weighed more – 70 pounds (32 kg).”  (Wikipedia, Special Atomic Demolition Munition)

“The yield was estimated to be 10 to 1,000 tons of TNT (42 to 4,184 GJ)”  (Wikipedia, Special Atomic Demolition Munition)

The problem is that the 0,5-1 kt nuclear device is not very big. Drones can transport and launch those suitcase nukes near strategic targets. Like radars and other vulnerable targets. The SADM-equipped drones can cause very big damage to those systems. SADMs were developed in the USA and the Soviet Union, and the USA stopped that program at least at the end of the Cold War. But there is a possibility. The ex-Soviet developers sold that technology to other countries, including Israel and North Korea. 

There were many jews who moved away from Russia. after the Soviet Union collapsed. And maybe some developers who worked in the Soviet weapon development projects were jews, or marked themselves as “jews”. And the Ukraine war causes thoughts that maybe Russian scientists also delivered SADM-manufacturing technology into North Korea. 

And maybe Russians didn’t remove their own SADM weapons from the stockpile. The problem with SADM is that the commando troops can use those devices. But also, drones and lightweight torpedoes can carry the SADM detonator. There are many actors who want this type of weapon in their hands.
