Overview

The Authority intends to procure approximately 200 closed-circuit mixed gas diving life support systems to replace and renew military diving capability for the Royal Navy and associated users undertaking underwater defence tasks. The capability is expected to remain in service for approximately 10 years and is intended to support worldwide operational deployments and training.

The solution is expected to comprise a robust, low-maintenance, electronically monitored and controlled closed-circuit mixed-gas rebreather system with depth-appropriate bailout systems, low magnetic and acoustic signatures, and the ability to integrate with other life support systems. The solution is expected to support dry, wet and simulated training scenarios, including fault insertion for training purposes.

It should be suitable for military diving operations across a wide range of operating environments whilst remaining operable in austere climatic conditions. The Authority is seeking improved dependability, employability and safety through enhanced human factors, reduced user burden, simplified maintenance and streamlined pre-dive preparation.

Additional details

The procurement is also expected to include associated training solutions, maintenance, technical documentation, spares and in-service support arrangements. This notice is provided for advance market awareness only and does not commit the Authority to undertake the procurement described. All aspects of the requirement, including scope, quantity, technical specification and timescales, remain subject to change.
