Notice Title

715409453 - Personal Location Transmitters (PLTs) - UK4

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.
