KUB-BLA
Russian delta-wing loitering munition developed by ZALA Aero (Kalashnikov Group), designed for strikes against personnel and light vehicles with a significant warhead.
System Overview
What It Is
The KUB-BLA (also known as KYB-UAV or ZALA KUB) is a delta-wing loitering munition developed by ZALA Aero as a complement to the Lancet system. While the Lancet is optimized for precision strikes against point targets, the KUB-BLA is designed for strikes against softer area targets with its high-explosive fragmentation warhead.
How It Works
The KUB-BLA is launched from a ground-based rail and uses an electric motor for quiet approach. It carries an electro-optical camera that transmits video to an operator, who can identify targets and direct the drone into a terminal dive. The delta-wing design provides good loitering characteristics. The HE-FRAG warhead is optimized for anti-personnel and anti-material effect against unarmored or lightly armored targets.
Primary Capability
One-way attack against area targets, personnel concentrations, and light vehicles using a larger warhead than the Lancet.
Combat Record / Operational History
The KUB-BLA was first confirmed in combat use in early 2022 during the initial phase of Russia's invasion of Ukraine. One of the earliest confirmed uses was a KUB-BLA found crashed but unexploded in Kyiv in March 2022, providing Western analysts their first close look at the system. It has seen limited use compared to the Lancet-3, which has proven more versatile and effective. The KUB-BLA appears to be used primarily against softer targets where its fragmentation warhead provides better area effect than the Lancet's shaped charge.
Overview
The KUB-BLA is a delta-wing loitering munition developed by ZALA Aero as part of the Kalashnikov Group's family of unmanned combat systems. Designed as a companion to the more precise Lancet-3, the KUB-BLA carries a high-explosive fragmentation warhead optimized for area effect against personnel concentrations and light vehicles rather than precision point strikes.
Technical Details
The KUB-BLA features a delta-wing planform with a wingspan of approximately 1.2 meters and weighs about 7 kg. It is powered by an electric motor, providing approximately 30 minutes of flight time and a range of about 40 km. The system carries a 3 kg HE-FRAG warhead and uses an electro-optical camera for operator-guided terminal attack. It is launched from a ground-based rail system and flies quietly to the target area before the operator selects a target from the video feed and initiates the terminal dive.
Combat History
The KUB-BLA first appeared in combat in the early days of Russia's full-scale invasion of Ukraine in 2022. An unexploded example found in Kyiv in March 2022 gave Western intelligence agencies their first opportunity to examine the system in detail. However, the KUB-BLA has seen relatively limited deployment compared to the Lancet-3, which has proven more versatile and effective in the Ukrainian theater. The KUB-BLA appears to have a niche role against soft targets where its fragmentation warhead provides superior effect.
Comparison with Lancet
While both systems are produced by ZALA Aero and share similar operational concepts, the Lancet-3 has clearly emerged as the preferred system. The Lancet offers better precision through its more advanced seeker, longer loiter time, and a shaped-charge warhead effective against armored targets. The KUB-BLA's fragmentation warhead is more suited to anti-personnel use, but the greater versatility of the Lancet has made it the dominant loitering munition in Russian service.
