SeaPort Next Generation

Contract Types

Definition

SeaPort-NxG (Next Generation) is the Navy's primary electronic platform for acquiring support services across 23 functional areas including engineering, financial management, program management, and IT. It is an IDIQ multiple-award contract vehicle that serves as the mandatory source for a wide range of Navy and Marine Corps service requirements.

SeaPort-NxG replaced the earlier SeaPort-e program and is managed by the Naval Sea Systems Command (NAVSEA). It uses a rolling admissions model — unlike most IDIQ vehicles, SeaPort-NxG accepts new contractor applications on a continuous basis, making it one of the most accessible large contract vehicles in the federal market.

SeaPort-NxG functional areas include:

  • Engineering, system engineering, and process engineering
  • Research and development support
  • Modeling, simulation, stimulation, and analysis
  • Prototyping, pre-production, and model-making
  • System design documentation and technical data
  • Software engineering and development
  • Reliability, maintainability, and availability
  • Human factors engineering
  • Configuration management
  • Quality assurance
  • Program management support
  • Acquisition and life cycle logistics support
  • Financial management
  • Information technology

How SeaPort-NxG works:

  • Zone assignments — The U.S. is divided into geographic zones. Contract holders are assigned to zones where they can perform work. You can apply for additional zones after award.
  • Task order competition — Navy activities post RFPs to SeaPort-NxG contract holders in the relevant zone. Proposals are evaluated and awards are made at the task order level.
  • Rolling admissions — New offerors can apply at any time. GSA evaluates proposals on a rolling basis and awards new contracts periodically.

Getting on SeaPort-NxG:

  • Submit a proposal through the SeaPort-NxG portal (seaport.navy.mil)
  • Demonstrate relevant past performance in your selected functional areas
  • Small businesses receive favorable consideration — the Navy has aggressive small business goals on SeaPort

SeaPort-NxG is particularly valuable for engineering and technical services firms. Once on the vehicle, actively monitor the SeaPort portal for task order opportunities — the Navy posts hundreds of new requirements annually.
