Mission-critical support to global defence programmes

TPG has a long track record of working as a trusted partner alongside our clients in the Defence sector to deliver strategically important air purification systems to submarine programmes.


We work with UK and International defence agencies and prime contractors in the specification, development, delivery and through-life support of life-critical atmosphere management systems to ensure that crews can operate safely and effectively for extended periods.

Case study - helping submariners breathe

Submariners rely on our combined oxygen generating systems (COGS) and CO2 removal systems to breathe.

Our smart technology uses electronically charged membranes to separate water into oxygen and hydrogen. We also use a novel way of managing the hydrogen, carbon monoxide and other gases to create the optimum safe environment. Despite having over 11,000 components the system is compact and we’ve reduced its size to meet the design specifications for the Royal Navy’s ‘Astute’ class boats and are refining it further for the UK’s future submarine programme.

The technology is tested for the highest performance and reliability, as the UK’s submariners put their trust in us to breathe hundreds of metres beneath the surface, in one of the world’s most inhospitable environments.
