The Naval Air Warfare Center Training Systems Division (NAWCTSD) has a requirement to provide PORTS technology based Surface Navy training systems. PORTS is a simulation architecture technology used in the design of many Surface Navy shore-based trainers. The current PORTS program is based on the use of a Commercial Off the Shelf (COTS) simulation engine called the Combined Tactical Training and Analysis System (CTTAS). CTTAS provides an instructor station and manages the simulation for each specific trainer being developed. The PORTS/CTTAS architecture forms the core of a family of trainer simulations. The program is intended to meet immediate and future training needs for the Surface Navy. Serco North America, LLC. (Serco), has ownership of and licensing rights to the CTTAS software. A single award, Indefinite Delivery/Indefinite Quantity Contract (ID/IQC) with a 5-year ordering period is anticipated. The anticipated contract value for this procurement is $49M in total. Program requirements are currently being fulfilled utilizing the PORTS Contract Number N6134020D0016. Prior to this, the PORTS ID/IQC, N6134011D0005 & N6134019C0048, were utilized to fulfill these requirements. The incumbent is Serco, for the aforementioned contracts.
