UK1 - Pipeline Notice
Summary of the contracting process

Defence Equipment and Support intends to procure around 200 closed-circuit mixed-gas diving life-support systems to renew military diving capability for the Royal Navy and associated users carrying out underwater defence tasks. The goods are expected to include rebreather systems and depth-appropriate bailout equipment, alongside training solutions, maintenance, technical documentation, spares and in-service support. The systems are intended for military diving operations, training and worldwide operational deployments, including use in varied environments and austere climates. This is a defence equipment requirement combining specialist diving apparatus with the support and training needed to keep the capability in service. The anticipated service life is around 10 years.

This is at the planning stage: the buyer has stated an intention to procure, but has not invited tenders. It expects to use a competitive flexible procedure. The planned procurement is one lot, and the buyer considers it suitable for small and medium-sized businesses. The stated estimated value is £19,166,666.67 excluding VAT (£23,000,000 including VAT). The expected contract period runs from 1 August 2030 to 31 July 2033, with a possible extension to 31 July 2035. The buyer expects to publish a future procurement notice on 1 February 2028; this is an indicative date, not a response deadline. The scope, quantity, specification and timescales remain subject to change.

This requirement is suited to suppliers with expertise in designing or supplying military diving life-support equipment and the ability to support it throughout its service life. The intended system is a robust, low-maintenance, electronically monitored and controlled closed-circuit mixed-gas rebreather, with low magnetic and acoustic signatures and the ability to integrate with other life-support systems. The buyer is looking for equipment that supports dry, wet and simulated training, including fault-insertion exercises, and remains usable in varied operating conditions. Suppliers should be prepared to address dependability, operational availability and safety through good human factors, reduced user burden, simplified maintenance and streamlined pre-dive preparation, as well as providing training, spares, documentation and ongoing support.
