The marine version of the KUB-UAV has been tested in Russia. Loitering ammunition was developed by Zala Aero (part of the Kalashnikov group of companies). This was reported by TASS with reference to the Kalashnikov press service.
The press service reported that the developer had tested a naval version of the KUB-UAV loitering ammunition. The development is based on the concept that was presented at the international forum “Army-2021”.
Kalashnikov also noted that the CUB-UAV is a universal means of destruction. The compact dimensions of the complex allow launching loitering ammunition from landing boats.
The KUB-UAV loitering ammunition was presented at the IDEX 2019 exhibition in Abu Dhabi. The declared speed of the drone is 130 kilometers per hour. The duration of the device is up to 30 minutes. The KUB-UAV can carry up to three kilograms of payload.
Earlier it became known about the development of technology for the use of kamikaze drones to protect the maritime borders of Russia. The new system will include reconnaissance drones and loitering ammunition.
In February 2019, The Washington Post compared a CUB-UAV to a Kalashnikov assault rifle. The author of the material suggested that the drone could revolutionize combat tactics. The advantages of loitering ammunition were attributed to ease of use.
