### Project T82 — DISN Systems Engineering Support

The Defense Information Systems Network (DISN) RDT&E Funding supports the following: DISN Networking: TR (formally known as Next Generation Networking Technologies): Provides engineering technical expertise to update the global network with the latest technologies. These new technologies provide protected and assured services for critical global, all theater support to the warfighter as well as other DoW and federal customers that consume services from the Defense Information Systems Network (DISN). Specific technical focus is on assured, dynamic global communications networks that can operate under various adversarial threat and risk conditions. Other RDT&E investments are made in ensuring operational and network operating systems that instrument and automate the operations, administration, maintenance, and provisioning functions creating a single DISN-wide view for network managers and operators. DRSN: Supports Peripheral and Component Re-Design between DRSN and its operators. The efforts within this program satisfy unique military requirements for multi-level secure voice services and conferencing capabilities in support of the Defense Red Switch Network (DRSN), a critical component of the National Military Command System (NMCS). Commercial equipment is not certified by the NSA to perform necessary encryption requirements of DRSN and Secure Voice Conferencing. Additionally, RDT&E funding supports the development, testing, and fielding of a prototype of the modern Multi-Level Secure Voice and Video (MLSV2) conference capability. The MLSV2 effort will provide a modern, flexible, and interoperable voice, video, and chat conferencing capability through standard protocols, interfaces, and hardware (HW) and software (SW) orchestration. MLSV2 will permit conferencing at three classification levels with one system. DoW Mobility: Mobility is leading the research, development, and deployment of Enterprise Controlled Unclassified Information (CUI) and classified mobile technologies. The goal of this effort is to increase information sharing and use of secure mobile devices across the global DoW. The continued evolution and expansion of mobility capabilities will revolutionize the way Combatant Commands, Services, and Agencies work by enabling on-demand access to services and information anytime, anywhere.

**Named R-3 performers** (share of this project's FY2027 R-3 total, so they need not reach 100%)**:** BAH (4.0, 38%), Airbus (1.7, 16%).

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| DISN Networking - TR (formally known as Next Generation Networking Technologies) | 5.2 | 4.8 | 4.8 |
| DRSN Peripheral and Component Re-Design and MLSV2 | 38.6 | 29.9 | 1.7 |
| Mobility | 3.9 | 3.9 | 4.0 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Industry primes | 54% | 5.7 |
| Other / unspecified | 46% | 4.8 |

**Top named industry performers:** BAH ($4.0M, 38%), Airbus ($1.7M, 16%).

> R-3 exhibit contract funding, not USAspending obligations.

## Mission & acquisition strategy

The Defense Information Systems Network (DISN) is the Department of War's (DoW's) consolidated worldwide telecommunications infrastructure that provides end- to-end information transport for DoW operations to the warfighters and the Combatant Commanders via a robust Command, Control, Communications, Computers and Intelligence information long-haul transport infrastructure. The DISN, seamlessly spanning the full spectrum from terrestrial to space and strategic to tactical domains, provides the interoperable telecommunications connectivity required to plan, implement, and support all operational missions, anytime.

DISN Networking - TR (formally known as Next Generation Networking Technologies) will use Technical Assistance (SETA) type entities to assist with cutting edge technology exploration, development, documentation and limited operational field deployment of prototype and next generation capabilities into the DISN. DRSN: Project to be conducted through partnership with NSA via existing interagency agreement.
