MK40/41 Fast Jet Life Preserver

Comprehensive Protection for Fast Jet Pilots

The MK40 / MK41 Fast Jet Life Preserver is specifically designed to safeguard pilots during flight, ejection, and water landings. This life preserver combines a flame-retardant waistcoat, an inflatable stole, and a blast-proof pouch to ensure reliable protection in the cockpit and post-ejection scenarios. Built for comfort and manoeuvrability, it offers modular features that can be customised to meet individual requirements and operational needs.

This lightweight, low-maintenance design is compatible with a variety of fast jet aircraft, including the BAE Systems Hawk, Harrier, Sea Harrier, Panavia Tornado, and the SEPECAT Jaguar. The MK40 / MK41 is trusted by air forces worldwide to protect fast jet pilots in some of the most demanding operational environments.

Performance

Designed for speed, agility and control, our solutions excel under the extreme demands of fast jet flight. By reducing pilot fatigue and supporting physical resilience, we enable greater endurance in high-intensity missions, helping ensure sustained performance and mission success, even in the most challenging conditions.

Innovation

We’re shaping the future of fast jet capability through next-generation innovation. From cutting-edge material sciences to advanced G-protection system architectures, our solutions are designed to enhance pilot performance and survivability. Innovative textiles and smart integration elevate protection and efficiency, setting new standards for the cockpit and beyond.

Protection

Protection in fast jet environments demands intelligent integration. Our systems are designed to safeguard pilots against thermal extremes, high-G forces and operational hazards. From cockpit survivability to environmental resilience, every element is engineered to preserve capability when it matters most.
