What project 0253 buys
AN/BVY-1 Integrated Submarine Imaging System (ISIS) will continue to add new capabilities via the Technical Insertion (TI)/Advanced Processing Build (APB) process while working with partner Submarine Warfare Federated Tactical System (SWFTS) programs to realign software development according to Development Security Operations (DevSecOps) software processes. The Navy is pursuing a cloud enabled containerization architecture transformation across SWFTS (PE 0604503N Project 0219, Project 0236, Project 0253, and Project 0775) to increase operational agility and resiliency at the speed of relevance. FY27 continues to maximize mast RDTE investment and optimizes production through two distinct development programs. First, the New Mast Capability Development Program builds on prior year investment by continuing to insert emerging technologies for future mast module production and begins early design of the Type 2S mast. Second, the Legacy Mast Improvements Program specifically focuses on incorporating mature technologies and design improvements into legacy masts; this effort provides substantial improvements to the large inventory of photonics and imaging masts. Both programs ensure that submarines can conduct operations in high intensity littoral environments, intelligence gathering, real time imagery, and support the safe and effective employment of surveillance and weapons systems. Finally, FY27 funds the TI-24/APB-24 DT and other tests that verify software improvements funded in previous fiscal years. The Navigation and Electro-Optical (E-O) program enables littoral operations by procuring ISIS, the production of low-profile photonics masts (Low Profile Photonics Mast (LPPM), Type 20, and Type 24), the maintenance and sustainment of periscope and legacy photonic masts, the production and sustainment of Universal Modular Mast Systems and Dip Loops, and the development of the ISIS inboard processing components of the Submarine Warfare Federated Tactical System (SWFTS). The Department of the Navy established the ISIS to rapidly field the Type 18 periscope, RADAR rangefinder, Type 8 Mod 4 Infra-red (IR) periscope system, and integrate existing periscope imagery systems into a single imaging system for installation on board SSN 688 class and SEAWOLF class submarines.

Project 0253 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

|---|---|---|
| FY2025 | Actual | 0.0 |
| FY2026 | Enacted | 39.3 |
| FY2027 | Request | 39.4 |
| FY2028 | Outyear | 40.0 |
| FY2029 | Outyear | 40.7 |
| FY2030 | Outyear | 40.9 |

4 accomplishments / planned programs
The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 1 of them describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
Commence the TI-28 capability development process which provides the necessary engineering, technical program, project and configuration management of the hardware and software baseline to incorporate additional sensitive software imaging algorithms, while concluding the development of TI-26.
Read the FY2027 plan →FY2027 planned work Continue investment in additional capabilities beyond the Type 24 baseline. Specific efforts include: - Developing technology candidates - Executing tests

Named performers on project 0253
Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
