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. ### Lot Information Lot 1 Options: The Authority may at its sole discretion exercise the Options to extend the Contract in respect of any Option Line Items on Schedule 2 (Schedule of Requirements) for the following periods: (a) Option Year 1 (Year 4) - 24th March 2029 to 23rd March 2030 and (b) Option Year 2 (Year 5) - 24th March 2030 to 23rd March 2031.
