Accelerate Mission Software Validation with Realistic Tactical Simulation

SADIE is NextGen Federal’s cloud-native Modeling & Simulation ecosystem that enables organizations to build, test, validate, and optimize mission software inside realistic operational environments before deployment.

By orchestrating leading simulation platforms, tactical network emulation, and automated DevSecOps pipelines, SADIE dramatically improves software reliability while reducing development risk, testing costs, and deployment timelines.

What is SADIE?

Modern Simulation-Based Testing for Mission Software

SADIE is NextGen’s proprietary Modeling and Simulation (M&S) ecosystem engineered to support development, validation, and operational assurance of APIs and software components in realistic military tactical environments. SADIE is the only fully integrated Modeling and Simulation as-a-service platform in the DoD marketplace that combines cloud-native test orchestration, multi-engine simulation integration (OneSAF, AFSIM, STK, NGTS, IEWTPT, VR-Vantage), and DDIL network emulation in a single Kubernetes-deployable solution.

Traditional software testing cannot accurately recreate the complexity of tactical operations. SADIE creates highly realistic operational environments where APIs, command-and-control applications, AI services, communications software, and mission systems can be continuously validated under real-world battlefield conditions.

The platform combines advanced modeling & simulation, tactical network emulation, automated orchestration, and DevSecOps workflows into a single enterprise platform.

Why Organizations Use SADIE

  • Validate Before Deployment: Test software under realistic mission conditions before fielding.
  • Continuous Simulation: Integrate automated simulation-based testing directly into CI/CD pipelines.
  • DDIL Ready: Evaluate systems under disrupted, disconnected, intermittent, and limited-bandwidth environments.
  • Multi-Domain: Support land, air, cyber, space, electronic warfare, intelligence, and tactical communications.
  • Cloud Native: Deploy anywhere Kubernetes runs.
  • Built for Government: Designed specifically for DoD mission systems and tactical software.

Platform Capabilities

One Platform. Multiple Simulation Engines.

SADIE orchestrates industry-leading simulation technologies through a unified workflow.

  • OneSAF: Entity-level Army operational simulation
  • AFSIM: Multi-domain mission simulation
  • STK: Space, RF, and sensor modeling
  • VR-Vantage: 3D visualization
  • MIDAS: API validation and performance analytics
  • IEWTPT: Electronic Warfare training
  • Tactical Network Emulation: DDIL communications validation

Why SADIE is Different

Integrated Simulation Ecosystem

  • No more manually connecting multiple modeling and simulation tools.

Automated DevSecOps

  • Simulation becomes part of every software build.

API Validation

  • Validate reliability, latency, throughput, scalability, and interoperability.

Operational Fidelity

  • Test software inside realistic mission environments—not laboratory conditions.

Mission Analytics

  • Generate actionable performance metrics with complete traceability.
