This procurement process falls under the services category, specifically focusing on software and hardware integration consultancy. The engagement is designed for the central government public authority. The preliminary market engagement deadline is set for 29th September 2025, with the actual contract period scheduled to commence on 1st September 2026 and conclude on 1st September 2031. DE&S is gathering industry insight, primarily seeking input for its procurement strategy regarding system integrations in air defence systems. The Land GBAD programme represents a significant opportunity for businesses specializing in systems integration, particularly those with experience in air defence capabilities. Companies offering expertise in software and hardware integration consultancy will find this project particularly promising, as it offers the potential for long-term involvement in a strategically important national defence initiative. Participating in the preliminary market engagement will allow businesses to showcase their capabilities, particularly in integrating complex systems to meet stringent security and functionality requirements. Successful collaboration could position companies as key contributors to a major national defence project with substantial growth prospects. ## Notice Introduction: The Authority is inviting responses from industry for market engagement about a 'Lead System Integrator' (LSI) Role for Land GBAD. Land GBAD (Ground Based Air Defence): The Land GBAD Programme was established in response to Army's requirement for a fully integrated Air Defence system of systems. This will be an enduring capability that will be delivered through incremental capability uplifts over the next 10 years. The Single Statement of User Need (SSUN) for Land GBAD is: 'Land-GBAD must provide sufficient, effective capability to warn, inform, deter and defeat selected air threats (including aircraft, missiles, munitions, and UAS), in order to prevent adversary interference from the air inhibiting Joint Force freedom of manoeuvre. Land-GBAD will provide lethal and non-lethal defeat mechanisms and minimise the risk it presents to friendly and neutral air users. It will be deployable on multi-domain operations, integrated, scalable up to divisional level, and in joint and multi-national operations to Protect, Engage, Constrain and Fight.' Capabilities to be delivered and enhanced by the Land GBAD programme include: - Short-Range Air Defence (SHORAD); - Medium-Range Air Defence (MRAD); - Specialist Counter Uncrewed Air Systems (S-CUAS) for SHORAD and MRAD; and - All Arms Counter Small Uncrewed Aircraft Systems (All Arms C-sUAS). The capabilities which make up the Land GBAD System of Systems (SOS) will be incrementally procured and delivered through a number of related contracts over a 10-year period, these will require a high level of integration and SOS testing. Land GBAD will also consider novel weapons, where they are effective and sufficiently mature. Lead System Integrator Role: Integration is a critical enabler for the Land GBAD Programme. The programmes requirements promote and require good integration, interoperability and use of open standards. Because of the scale of the integration required for Land GBAD, the Authority has identified a Lead Systems Integrator (LSI) role is required. The LSI will provide support to the Authority to manage technical and programme aspects relating to Systems of Systems integration and testing. The LSI roles and responsibilities will include: - Co-ordination and management of programme aspects and stakeholders. - Developing and maintaining Land GBAD architectures, to support technical and programme development. - SOS requirements management, and subordinate system requirements management, including change control. - SOS technical planning and plan development. - Defining and agreeing SoS interfaces. - Planning and conducting SoS trials. - Monitoring and managing system integration progress at SoS level, identifying steps from one-to-one system component integration to complete SoS integration. - SoS issues management and resolution. The LSI role intended to utilise industries' Systems Integration expertise, facilities and tools to leverage the delivery of the Land-GBAD requirement.
