Military diving and submarine escape and rescue operations demand equipment that performs reliably in some of the world’s most challenging environments. Hyperbaric capability remains a critical component of diver safety, emergency response and post-rescue medical treatment, ensuring personnel can receive life-saving care whenever and wherever it is required.
SOS Group is a UK-based manufacturer of foldable, lightweight hyperbaric chambers, with more than 35 years of experience in hyperbaric technology. For over 20 years, the company has actively participated in the NATO Submarine Escape and Rescue Working Group events organised by Sonistics showcasing out long standing partnership.
In 2020, SOS completed a US Navy Program for a Multi-Occupant Flexible Recompression Chamber System, and also released the Hyperlite DL5 a 5 Bar (6 ATA) Dual Lock Recompression Chamber.
Today, SOS Group supplies tailored hyperbaric systems to defence forces, naval organisations, law enforcement agencies and emergency services worldwide. Supporting military diving operations, submarine escape and rescue missions, humanitarian response and remote medical care, these systems provide trusted hyperbaric capability wherever operational requirements demand.

Hyperlite SL3 supports Exercise Viperfish Mercy 2026
SOS Group’s Hyperlite SL3 is involved in Exercise Viperfish Mercy 2026, highlighting the importance of rapidly deployable recompression capability in submarine escape and rescue response.
Hyperlite Multi Occupancy Foldable Recompression Chambers combine lightweight, flexible pressure-vessel technology with compact transport packaging and modular deployment. These features provide an exceptional rapid-response capability, supporting air delivery to a suitable vessel of opportunity and bringing treatment closer to submariners without waiting for a dedicated chamber-equipped ship.


The SL3’s multi-occupancy design allows an attendant to accompany a casualty during recompression, enabling hands-on care throughout treatment. Its portability supports a clear operational priority: getting recompression capability to the scene early, ready to support a life-saving response.
Arriving first. Treating submariners. Saving lives.
