Summary of the contracting process

The Submarine Delivery Agency procured Personal Location Transmitters (PLTs), formerly known as Personal Locator Beacons, for use on Royal Navy submarines. These man-overboard identification and location systems are intended to improve the likelihood of locating survivors after escape or abandonment during a distressed-submarine scenario. The requirement covered 2,132 PLTs, with an option for 1,192 additional units and a tasking mechanism for ad hoc purchases. This is a defence goods requirement delivered in the United Kingdom. The buyer is the Submarine Delivery Agency, part of central government. The procurement relates to equipment supporting submarine escape, abandonment and survivor-location operations, rather than general maritime rescue equipment or routine submarine construction. The opportunity was identified as suitable for small and medium-sized enterprises.

The procurement has been awarded following an open procedure under the defence and security regime. Three bids were received, including two from SMEs. Marine Rescue Technologies Ltd was selected on 11 August 2026 for £1,567,679.52 gross (£1,306,399.60 excluding tax). The contract was signed on 10 September 2026 and runs from 10 September 2026 to 9 September 2029, with two option years extending the maximum period to 9 September 2031. The award notice records a contract start of 1 September 2026 and a maximum end date of 1 September 2031. The original estimated value was £2,500,000 gross (£2,083,333 excluding tax). Evaluation weighted technical, non-cost quality at 70% and tender cost at 30%. Economic and technical selection criteria applied.

This procurement demonstrates demand for specialist personal-location equipment used in submarine escape and survivor recovery, with a requirement for reliable supply at defence scale. A credible competitor would need to design, manufacture or integrate PLTs suitable for carriage on Royal Navy submarines and capable of supporting identification and location in a distressed-submarine scenario. Evidence of technical competence and financial capacity would be important, as both formed part of supplier selection. The contract’s performance measures show that suppliers must manage scheduled delivery, provide reporting to agreed timescales and monitor equipment returned because of defects. Businesses with established quality assurance, product acceptance processes, fault investigation and responsive after-sales support would therefore be well placed. The requirement also indicates potential value in flexible supply arrangements that can accommodate additional units and ad hoc tasking.

Notice Title

715409453 - Personal Location Transmitters (PLTs)

Notice Description

Personal Location Transmitters (PLTs), formerly referred to as Personal Locator Beacons (PLBs), are man-overboard identification and location systems carried on all Royal Navy submarines. They play a critical role in increasing the likelihood of locating survivors following an escape or abandonment during a Distressed Submarine (DISSUB) scenario. The Submarine Delivery Agency (SDA) has an operational requirement to procure PLTs. Under this contract, the SDA seeks to acquire 2,132 PLTs, with an option to purchase an additional 1,192 units during option years 4 and 5. The contract also includes a tasking mechanism that enables ad hoc procurement if required. The Platform Equipment Delivery Team (PEDT) will conduct a competitive process to assess, select, and award a contract for the delivery of PLTs to meet this requirement.
