In the world of defense technology, adaptability is everything. Missions evolve, environments shift, and teams need technology that can keep up without bogging them down. That’s exactly where Curtiss-Wright’s new PacStar® Universal Smart Chassis steps in.
If you’re already familiar with the PacStar ecosystem, you know it’s all about portable, ruggedized systems that bring enterprise-grade computing and networking to the tactical edge. But the new PacStar Universal Smart Chassis takes that capability to another level. It lets you mix and match existing modules, upgrade incrementally, and maximize your investment without a full system overhaul.

The Challenge: Networks on the Move
Tactical teams today are being asked to do more with less. They need high-performance compute and networking in smaller, lighter packages, and systems that can move easily between vehicles, command posts, and forward-deployed locations.
At the same time, technology never stops advancing. New mission software demands more processing power, more bandwidth, and better integration with sensors, communications, and ISR systems. The problem is that replacing or re-engineering entire hardware systems every few years isn’t practical or affordable.
That’s the gap Curtiss-Wright is closing with the PacStar Universal Smart Chassis. It’s built to help users modernize on their own terms and extend the life and capability of PacStar gear they may already own, while seamlessly integrating new technology.
What’s New: Mix, Match, and Optimize
So, what’s new here? PacStar Universal Smart Chassis is the first of its kind that lets users combine PacStar 200-Series and 400-Series modules in the same chassis.
That means a single compact enclosure can hold:
- Up to eight PacStar 200-Series modules
- Up to four PacStar 400-Series modules
- Or a combination of both
PacStar Universal Smart Chassis enables users to customize combinations of PacStar tactical networking modules depending upon mission needs
It’s a bit like having the best of both worlds. You have the smaller, lower SWaP of the new PacStar 200-Series, plus the breath and proven performance of the PacStar 400-Series, all running together without compromise.
PacStar Universal Smart Chassis offers:
- High compute density — it supports compact tactical processors like PacStar 251 server, PacStar 221 switch, and PacStar 211 router. You can scale compute and networking resources exactly as needed
- Integrated UPS and battery — ensuring uninterrupted operation even when power sources are unstable or temporarily unavailable
- Wide range, filtered DC power input — supports payloads up to 350W, so you can drive demanding configurations without worrying about power drops.
- AC input conditioner — powers two chassis simultaneously and accepts worldwide voltages, making it ready for global deployment
- Full compatibility — it works with existing PacStar frames, cases, and mounting solutions, meaning you don’t have to redesign your entire setup
In short, we didn’t just build a new box. We built a smarter way to reuse, combine, and expand existing capabilities.
Why This Matters: Flexibility Meets Cost Efficiency
In tactical environments, logistics matter as much as performance. Every pound of gear counts, every watt of power matters, and every dollar saved on system redesign can be redirected to high-priority mission needs.
By enabling users to reuse PacStar 400-Series modules alongside the newer PacStar 200-Series components, the Universal Smart Chassis reduces both cost and complexity. Instead of phasing out older modules, teams can keep using them and blend them with the latest technology to optimize performance and efficiency.
That’s especially valuable for organizations looking to modernize incrementally, rather than all at once. Whether you’re expanding compute capacity, upgrading network switches, or adding new routers or radio gateways for advanced IP network capabilities, the Universal Smart Chassis lets you do it modularly and affordably.
Looking Ahead: Building on a Proven Foundation
Our Universal Smart Chassis isn’t a one-off innovation. It’s part of Curtiss-Wright’s broader strategy to deliver modular, interoperable systems that can evolve alongside mission needs. It joins a proven family of PacStar Modular Chassis solutions that have already earned trust across defense, government, and commercial sectors.
And as communication demands continue to grow — from edge computing to data-heavy ISR operations — solutions like this one will play a key role in keeping networks efficient, secure, and mission-ready.
The Bottom Line
PacStar Universal Smart Chassis represents more than just new hardware. It’s a smarter approach to modernization that helps tactical teams get more from what they already own, while preparing for what they need next.
By bringing together the power of the PacStar 200-Series and 400-Series in one flexible, compact design, Curtiss-Wright is giving users the tools to scale and adapt, even during a mission.
In today’s ever-changing mission environments, that kind of flexibility isn’t just convenient — it’s essential.
