Serbia has revealed a new short-range air-defence missile, the M-4 (BR-4), at the Partner 2025 exhibition. The system is intended to intercept unmanned aerial vehicles and low-flying munitions at close ranges, offering a quick-reacting, low-cost layer of protection for troops and critical infrastructure.
According to the manufacturer, the M-4 has an effective range of up to 4 kilometres and a top speed of 700 metres per second. The missile weighs 4 kg and carries a 1 kg warhead. It uses wireless guidance combined with a dual-spectrum infrared electro-optical seeker to improve tracking accuracy and resistance to electronic countermeasures.
The weapon can operate in fully automatic or semi-automatic modes and may be deployed from fixed emplacements or mounted on vehicles, giving commanders flexibility in how it is fielded. Designed to complement longer-range air-defence systems, the M-4 emphasises rapid response, operational flexibility and affordability — attributes seen as increasingly important in countering proliferating small, cheap aerial threats.
Developers say the missile will bolster local and point-defence capabilities against contemporary aerial threats, providing a practical option for protecting forward units and vital infrastructure.
