    Brief

    The Design and Systems Integration Partner will serve as the custodian of the TacNet design platform on behalf of the Ministry of Defence (MOD). This role encompasses the technical responsibilities traditionally held by a Design Authority while the MOD retains ultimate decision-making authority over system design. The partner will manage the integration of new situational awareness capabilities and equipment into the TacNet family of solutions, while maintaining strict impartiality and independence from third-party suppliers and their commercial interests. Suppliers should note that this is a strategic partnership opportunity to lead the technical governance and evolution of a critical military capability.
