MK21 Crew Lifejacket

Enhanced Safety and Flotation for Aviation Crew Members

The MK21 Crew Lifejacket is designed to provide critical emergency flotation for aviation crew members during aircraft ditching situations. Backed by our five decades of experience and over 1 million lifejackets produced, this lifejacket offers unmatched reliability, making it the trusted choice for leading aviation organisations around the world.

CAA-approved, the MK21 features a single chamber that ensures the wearer is automatically positioned face-up in the water, even if unconscious. Its lightweight design and compact structure allow for quick and efficient deployment, ensuring crew members are well-prepared in emergency situations.

Performance

In aviation, performance means more than function, it means readiness under pressure. Our lifejackets and crew safety systems are engineered for rapid deployment, reliable flotation, and operational endurance across both civil and military platforms. Whether supporting commercial aviation or tactical flight operations, they deliver consistent, trusted performance when it counts.

Innovation

We advance crew safety through continuous innovation in design, materials and survivability technology. From lightweight lifejackets for civil aviation to high-performance systems for rotary and fixed-wing aircrew, our products are shaped by real-world feedback, evolving regulatory requirements and a commitment to continually raising the standard in aircrew protection.

Protection

Crew protection is central to safe and effective aviation. Our life-saving systems are designed to perform in high-stress, high-consequence environments, providing flotation, thermal protection and secure fit across a range of mission and commercial profiles. Certified and rigorously tested, they help protect lives at altitude, on approach, or in emergency descent.
