# Joint Development Environment (e.g., build, manage, and test both payload and common services)

**R-2A activity** of project CY50W1 — Cyber Weapons/Tools  
**Program element:** 0306250JCY — Cyber Operations Technology Support  
**Component:** Defense-Wide · **Budget Activity:** 7  
**Vintage:** President's Budget PB2027  
**Canonical URL:** https://hitchintel.com/programs/0306250JCY/CY50W1/a2

## Summary

This activity requests $53.1M in FY2027, 28% of project CY50W1, down 6.0% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** In FY 2027, $53.120M will enable the JDE program to continue supporting approximately 2,500 users across the JDE U and JDE TS environments. The program will maintain connectivity and interoperability across existing environments to ensure timely capability deliveries to the Cyber Mission Force.

**FY2026 to FY2027 change.** The $3.38 million decrease reflects Department level prioritization decisions. As a result, JDE will focus on sustaining essential development environments and maintaining critical services required to support capability delivery to the Cyber Mission Force.

## Before the request year

**FY2026 plans — current year.** In FY 2026, the $56.500M enables the JDE program to expand access to the unclassified development environment (JDE U) to an additional 1,500 mission stakeholders. The program will also establish a new classified development environment (JDE TS) to support 1,000 USCYBERCOM capability developers, enabling secure collaboration and testing at higher classification levels.

**FY2025 accomplishments.** Funding expands the development environment to higher classification levels (including the ability to transfer between the networks) and expands options for more easily incorporating solutions developed by entities without direct access to any level.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 61.2 |
| FY2026 | Enacted | 56.5 |
