UK2 - Deployable Maritime Secure Analysis Capability – Preliminary Market Engagement

This notice is issued for preliminary market engagement only. It is not a call for competition, an invitation to tender or a commitment to procure. Participation is voluntary and at the supplier's own cost; responses are not scored. Any competition will be conducted under a separately published tender notice and will be open to all suppliers meeting its published conditions of participation, whether or not they took part in this engagement. The Authority anticipates a competitive flexible procedure under the Procurement Act 2023, subject to approval, and is considering whether a paid development stage may form part of that procedure.

To receive the RFI a supplier must submit the expression of interest described below and provide sufficient information to allow the Authority to verify: (a) its legal identity and that it is not excluded from public contracts; (b) its ownership; (c) its relevance to at least one area of interest in this notice; (d) its ability to contract with the Authority; and (e) its acknowledgement that the RFI is marked OFFICIAL-SENSITIVE and will be handled on a need-to-know basis in accordance with the handling instructions issued with it. Registration on the Defence Sourcing Portal is required. These checks control access to the RFI only; they are not a procurement evaluation or pre-qualification for any future competition. Facility Security Clearance is not required to receive the RFI. Overseas suppliers may take part provided they can contract with the Authority and comply with the handling conditions.
