The Sonar Employment Trainer (SET) provides acoustic operator employment Fleet and team training for submarine sonar systems. SET is used to train advanced operators in the Advanced Sonar Employment and Sonar Supervisor courses. The SET is periodically upgraded to support current software Advanced Processor Builds (APBs) and Technical Insertions (TIs). Live Signal Playback capability is provided from this line for the SET, COAET and Multi-Purpose Interactive Trainer (MIT) with Submarine Training And Tactics Unified Schoolhouse (STRATUS) to support distance training. COAET provides operator and introductory team training to submarine force personnel prior to entry into the Submarine Multi Mission Team Trainer (SMMTT) as well as supplemental training to off-load the heavily utilized submarine attack center trainers. COAET utilizes partial tactical builds and emulations of the latest Sonar, Combat Control, Imaging and Electronic Warfare Systems which provide an environment substantially equivalent to that found on board ship, thus enabling students to develop and maintain the attack center familiarization to support Fleet operations. COAET supports individual operator/pipeline training at the Submarine Training Facilities. These training systems and Training Enhancement Changes (TECs) are identified by the Submarine Learning Center (SLC) and approved by the Fleet Type Commanders, for use at the Submarine Training Facilities. [P40A / TD 500 ATTACK CENTER TRAINERS]: SUBMARINE MULTI MISSION TEAM TRAINER (SMMTT) line procures shore based Combat System Team Trainers capable of training personnel in all aspects of submarine approach, attack and surveillance operations in a controlled, simulated environment to achieve submarine force readiness levels. The requirement matches the shore based configuration to the fleet modernized Hardware/Software(HW/SW) tactical builds. This includes the required capability to connect Attack Centers internally or externally using point to point technologies for dual crew training on Cooperative Engagement, Undersea Battle Problems and Extended Battle Problems as directed by the Fleet and the Aggressor Squadron. SMMTT trainer supports operator, employment, strike, and Battle Group training for enlisted and officer pipelines. SMMTT supports SSN/SSGN/SSBN crew certification and Fleet Responsive Training. SMMTT integrates Combat Control, Acoustics and Electronic Warfare systems with the All World Environment Simulation to provide realistic simulation using Authorized Navy databases and programs. This line includes modifications to the functionality of the Periscope Simulator (PSIM) to provide common imaging training for submarine attack centers. Submarine attack centers support real world recorded sensor data for playback in the training environment. This line also includes Engineering Production Model (EPM) to manage the additional TI/APB and Trainer Enhancement requirements as directed by the TYCOM.

[P3A / Submarine Attack Center Modifications]: Submarine Attack Center Modifications line upgrades hardware, software and simulation to match current Fleet configurations.
Justification
Justification — Submarine Training Device Mods
The overall FY2026 budget decreased in value as compared to FY2025. Four of the Fleet Responsive Team Trainers' capabilities are realized in the Submarine Attack Centers, eliminating the need to modernize these trainers. The budget supports Undersea Warfare requirements. FY2026 adds funding for procurement and delivery of Columbia Class trainer equipment. This budget will allow the ability to support crew certification and deployment events for Columbia readiness. The FY 2026 request was reduced by $6.180 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." TD 300 NAVIGATION TRAINERS - 3.3 COLUMBIA SAFETY OF SHIP TRAINER - FY2026 adds funding for procurement and delivery of Columbia Class trainer equipment. This budget will allow the ability to support crew certification and deployment events for Columbia readiness. TD 400 COMBAT CONTROL ACOUSTIC TRAINERS 4.1 FLEET RESPONSIVE TEAM TRAINERS - FY2026 reduces quantity procurement from five to one. This procures one Sonar Employment Trainer (SET) to support officer and enlisted pipeline training and Fleet responsive training. Supports TYCOM requirement for pipeline and accession training.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
