Engineering-led ordnance, ballistics & concept-to-prototype development.
Southwest Services LLC — defense product development in smart munitions, fuzing, and Safe & Arm design, backed by validated ballistic analysis and in-house fabrication since 1998.

Engineering-led development from first concept to delivered hardware.
We support defense programs where the engineering is the hard part — guided projectiles, fuzing, and warhead systems that must perform under extreme launch, flight, and terminal conditions. Analysis, design, and fabrication are kept under one roof so design intent carries cleanly through to validated prototype hardware.
Alongside defense work, the same engineering discipline is applied to select commercial systems — from render-safe robotics to industrial safety enclosures.

Integrated disciplines across the ordnance lifecycle.
Five core practice areas work together — analysis informs design, design drives fabrication, and test data feeds back into the next iteration.
Capabilities & Ordnance Design
Ammunition, warhead, and Safe & Arm / fuzing design — all calibers, to ANSI Y14.5M drawing standards.

Interior, exterior, and terminal ballistics using IBHVG2, DATCOM, 6-DOF trajectory codes, and CTH hydrocode.
View detailsAnalysis & Modeling
Structural FEA, lethality/effectiveness modeling, and kinematic system simulation for ordnance programs.
View detailsFabrication & Test
In-house CNC turning and milling, precision inspection, and environmental and ballistic test equipment.

Depth over breadth.
What distinguishes defense engineering you can stake a program on.
Analysis before hardware
Every SWS design decision traces to ballistic and FEA simulation before the first chip falls in the shop. Hardware confirms analysis — it does not replace it.
Single-roof control
Design, analysis, fabrication, and test kept under one roof. Intent carries cleanly from the first drawing through the delivered, tested prototype — no handoff loss.
25 years, one domain
Two and a half decades of exclusive focus on ordnance, fuzing, and ballistic engineering. No scope creep into unrelated markets — depth over breadth.
A quarter-century of ordnance design, grounded in analysis.
Over 25 years of design experience spanning ammunition, warheads, and fuzing — supported by industry-standard interior, exterior, and terminal ballistic codes and ANSYS finite-element analysis. Every design decision is traceable to engineering rationale and simulation.
