This is an advance notice for a follow-on Ship Acquisition Program Manager (SHAPM) requirement for Team Submarine. The solicitation is planned to be released within the next two weeks. The opportunity is exclusively for a task order under the SeaPort-NxG MAC, meaning only companies with an active SeaPort-NxG MAC award may submit a proposal as a prime contractor. Draft documents, including the Statement of Work, are attached to this notice. Proposals will not be submitted via the SeaPort Portal, though questions must currently be submitted there.
