Krasukha

Krasukha is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Krasukha rather than just read about it. In short: The Krasukha (Russian: Красуха; English: Belladonna or Deadly Nightshade) is a Russian mobile, ground-based, electronic warfare (EW) system. This system is produced by the KRET corporation on different wheeled platforms.

Key takeaways

Krasukha belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Krasukha to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Krasukha from memory before moving on to harder problems.

Reference excerpt

The Krasukha (Russian: Красуха; English: Belladonna or Deadly Nightshade) is a Russian mobile, ground-based, electronic warfare (EW) system. This system is produced by the KRET corporation on different wheeled platforms. The Krasukha's primary targets are airborne radio-electronics (such as UAVs) and airborne systems guided by radar. The Krasukha has multiple applications in the Russian Armed Forces, has been deployed beyond Russia's borders, and supplied to additional armed forces, such as those of Iran.

Krasukha-2 The Krasukha-2 is an S-band system designed to jam Airborne Early Warning and Control (AWACS) aircraft such as the Boeing E-3 Sentry at ranges of up to 250 kilometres (160 mi). The Krasukha-2 can also jam other airborne radars, such as those for radar-guided missiles. The missiles, once jammed, then receive a false target away from the original to ensure that the missiles no longer pose a threat. The Krasukha-2 guards mobile high-priority targets such as the 9K720 Iskander SRBM.

Krasukha-4 The Krasukha-4 is a broadband multifunctional jamming station mounted on a BAZ-6910-022 four-axle-chassis. It complements the Krasukha-2 system by operating in the X-band and Ku-band, and counters airborne radar aircraft such as the Joint Surveillance Target Attack Radar System (JSTAR) Northrop Grumman E-8. The Krasukha-4 has enough range to effectively disrupt low Earth orbit (LEO) satellites and can cause permanent damage to targeted radio-electronic devices. Ground based radars are also a viable target for the Krasukha-4.

Operational history Krasukha jammers were reportedly deployed to support Russian forces in Syria. They have reportedly been blocking small U.S. surveillance drones from receiving GPS satellite signals. During the Turkish intervention in the Syrian civil war, the complex apparently destroyed a Bayraktar drone by causing it to lose control, subsequently crashing. The Israeli Defense Force had problems in 2021 with the Krasukha S-4 GPS denial system, which led to Israel's successful development of non-GPS weapons targeting and anti-GPS-jamming technology. In July 2018, an OSCE monitoring mission drone recorded a 1L269 Krasukha-2 among other electronic warfare equipment deployed near Chornukhyne, Ukraine. In 2018, Russia’s Krasukha-4 microwave cannon reportedly grounded an American AH-64 Apache attack helicopter in Syria by damaging its electrical circuits. In 2020, Krasukha was claimed (without evidence) to have operated around the Russian military base at Gyumri in Armenia to counter the use by Azerbaijan of Turkish-made Bayraktar TB2 armed drones as well as Israel-made Harop loitering munition (suicide drones). The first export contract was officially signed in August 2021. Krasukha-4 models are also being employed in the ongoing Russian invasion of Ukraine, as Ukrainian forces captured one of these devices in the field near Kyiv. A photograph posted to social media claims to show part of the system, which has been separated from its truck mount and shows some damage. The unit was then sent to the United States for examination. On 9 August 2023, a source in the Russian defense industry told the state news agency TASS that several Southeast Asian nations and an Eastern European country have ordered the Krasukha and Sapphire EW systems. In August 2025, it was confirmed that Russia had supplied Iran with Krasukha EW systems.

Worked examples

Example 1 — a first encounter with Krasukha

Start with the simplest possible case. Write down what Krasukha claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Krasukha before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Krasukha ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Krasukha

In research: Krasukha appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Krasukha in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Krasukha is common in secondary-school and first-year university syllabi. It links to neighbouring topics Concern Radio-Electronic Technologies, Electronic warfare, Electronic warfare equipment, so understanding it makes those chapters shorter.
In everyday life: Look for Krasukha outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Krasukha in simple terms?

Why does Krasukha matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Krasukha?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
