Systems Engineering and Modeling and Simulation

From Complexity to Mission-Ready

Founded by an engineer with more than 20 years in aerospace and defense engineering.

Systems engineering applied directly to your program, scoped to a defined problem and a defined deliverable.

What We Do

SentinelDT Consulting LLC is a small US engineering firm (NAICS 541330) in Huntsville, AL, working in systems engineering, modeling and simulation, and verification of modeling and simulation evidence. We build analysis, simulation, and after-action software for air operations training, exercise, and analysis.

20+ Years, founder’s engineering experience
3 Engagement Formats
Huntsville, AL Base of Operations

When critical domains stay disconnected, execution slows

Most programs operate with fragmented engineering visibility. Requirements live in one tool, architecture in another, test results in a third. The result: delayed decisions, duplicated effort, and risk hiding in the seams.

Disconnected Systems

Engineering data trapped in siloed tools with no integration layer to connect requirements, architecture, and test.

Slow Decisions

Program leadership waiting weeks for engineering status because data must be manually aggregated across domains.

Fragmented Visibility

No single view of program health: risks surface late, dependencies are missed, and teams work with incomplete context.

Execution Drift

Programs start aligned but gradually diverge as engineering artifacts fall out of sync with operational intent.

Mission

Senior systems engineering expertise, applied directly to your programs

Our founder and technical lead has more than 20 years in aerospace and defense engineering. That includes more than twelve years as a Senior Systems Engineer on the NATO tri-national MEADS program. His roles there covered independent technical architecting, requirements compliance, and analysis of alternatives; modeling and simulation development; independent verification, validation, and accreditation as a subject-matter expert; and the interface with the NATO management agency.

Defined Scope

Clear deliverables and bounded engagements under a written statement of work with defined scope.

Senior Delivery

Our founder does the work.

Direct Access

No account managers, no junior staff.

Core Services

Three engagement formats, each scoped for speed, rigor, and defined outcomes

Program Integration Assessment

We map the integration gaps across engineering, program, and operations, find where decisions stall, and deliver a prioritized roadmap. Fixed scope, 3 weeks.

Deliverables: integration gap map, prioritized roadmap, executive decision brief.

Modeling and Simulation Evidence Review

A review of whether your modeling and simulation evidence supports the technology readiness level you claim. We assess the evidence; you own the number. SentinelDT does not assign, rate, or confirm a readiness level. Fixed scope, 4 to 6 weeks.

Deliverables: evidence review report.

Advisory Retainer

Ongoing architecture and requirements reviews for programs in modernization. Senior engineering judgment on retainer. Month-to-month, 30-day written notice.

Deliverables: architecture and requirements reviews.
