Blizzard is a high speed, modular, multi-mission vehicle, designed to carry a range of payloads. Operated independently or as part of a collective, Blizzard facilitates collaborative effects on a target - providing operational advantage over adversary systems.
It forms part of a strategic partnership between the two companies centred around collaboration on a range of uncrewed autonomous air systems. The partnership capitalises on the investments and experiences that each company has gained over decades in this domain, including lessons learnt from a range of legacy platforms.
The initial system will be designed with modularity and adaptability for different missions, and offer multiple launch options such as air drop, ground launch, maritime launch and launch from a wide-body logistic aircraft.
The TRIDON Mk2 is one of the most effective anti-aircraft systems today, out-performing any other gun of calibre 40 mm or less. It is the product of evolution brought about by nearly 90 years of experience – fighting the bad guys since 1936.
Able to combat multiple threats quickly, the TRIDON Mk2 is a high-precision, cost-effective system that is easy to deploy and simple to maintain. Its modular design allows it to adapt to changing needs and to grow with new technologies.
The system is designed with flexibility in mind and is capable of combating everything from drones and cruise missiles, to aircraft and armoured vehicles – creating security and protection for both military forces and civil infrastructure.
The TRIDON Mk2 is a modern anti-aircraft system for today’s warfare. Specialized in filling the gaps behind expensive missile systems, it meets the growing need for air-denial weapons, providing a low-cost, rapid anti-aircraft system crucial for keeping the skies clear.
