### Project S200 — Advanced Technology Development

This project provides for rapid prototyping, Advanced Technology Demonstrations (ATDs) and Joint Capability Technology Demonstrations. It is a means for demonstrating and evaluating the utility of emerging/advanced technologies in operationally relevant environments with Special Operations Forces (SOF) users. This project integrates disruptive solutions and emerging technologies and then presents them in technology demonstrations, in conjunction with joint experiments and other assessment events. Evaluation results often facilitate the initiation of new programs and the insertion of appropriate technologies to acquisition programs. This project leverages key stakeholder relationships with the Department of Defense and government technology developers to address unique, joint special mission or area-specific needs for which a few rapid prototypes must be developed on a responsive basis, or of sufficient time sensitivity to accelerate prototyping efforts of a normal acquisition program in any phase.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| SOF Special Technology Project | 75.9 | 75.8 | 75.3 |
| High Speed Vertical Takeoff and Landing (HSVTOL) | 73.2 | 48.8 | 25.0 |
| Classified Sub-Project | 7.7 | 7.4 | 9.3 |

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

### Project SF101 — Engineering Analysis

This project provides a rapid response capability to support Special Operations Forces (SOF) programs and capabilities across the enterprise. The purpose is to correct system deficiencies, improve asset life, and enhance mission capability through the means of feasibility studies, analysis of alternatives, pre-developmental risk reduction studies, and engineering analyses. This project provides the engineering required to improve the design and performance integrity of the SOF equipment and software and to integrate disruptive “off-the-shelf” technologies to meet current and emergent capability gaps. This project also conducts risk reduction studies, analyses, and demonstrations to support emerging, time-critical equipment, weapons, and sensor enhancements.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| National to Theater Engineering Analysis | 2.4 | 2.5 | 2.6 |
| Engineering Analysis | 12.7 | 12.1 | 10.0 |
| Experimentation Force | 3.8 | 3.2 | 3.9 |

## Mission & acquisition strategy

S200 Advanced Technology Development This project conducts rapid prototyping and Advanced Technology Demonstrations (ATDs). ATDs provide a means for evaluating the utility of emerging/advanced technologies in operationally relevant environments with Special Operations Forces (SOF) users. Evaluation results are included in a transition package, which assists in the initiation of or insertion into an acquisition program.
