Why Choose Metromatics’ 19-Inch MIL-STD Comms Racks

19 Inch MIL STD Comms Electronic Equipment Racks

Metromatics proudly designs and manufactures specialised 19-inch Comms Racks, which are tailored to securely house important electronics in the Australian Naval vessels and submarines. Systems such as servers, workstations, UPS Systems, network switches and much more.  Our racks are engineered to meet stringent military standards, ensuring optimal performance in unique and challenging environments.

What Makes 19-Inch Comms Racks Essential?

Firstly, according to Wikipedia the term “19-inch rack” is a standard size.  Referred to by the IT and communications industry. It refers specifically to the size of the front panel of the equipment to be installed. Therefore, any rack mountable equipment that is labelled for use in a 19-inch rack will fit into a rack of that width.  Generally, the equipment itself is usually a bit narrower than the 450mm (19”).  This is to ensure it can be securely attached to the metal rails which hold the electronics systems inside the rack.  In addition, this standard size helps make sure that equipment from different companies will all fit together in the same rack.

Secondly, the height of the rack-mountable electronic equipment is measured in “U” or rack units.  This is where 1U equals 1.75 inches.  Therefore, the height can vary significantly – from 24RU to 38RU and even 42RU.  Metromatics offer this manufacturing flexibility based on the spatial and functional requirements of the naval vessels on which they are installed.  The depth is also customisable, which underscores our commitment to meeting specific customer needs.

Key Differences Between MIL-STD Racks and Commercial 19” Racks

1. Lightweight Design

Our MIL-STD Racks are significantly lighter than their commercial counterparts. This is crucial for naval applications where every kilogram matters, affecting the vessel’s speed, fuel efficiency and payload.

2. EMI/RFI Shielding

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) is detrimental in the densely packed electronic environments of naval vessels. Our comms racks feature superior shielding.  Therefore, preventing such disturbances, ensuring that sensitive equipment operates without disruption.

3. Military Standard Compliance

Metromatics doesn’t just make racks that fit standard sizes. We also design and build them to meet various MIL STDs. If needed, we can arrange for independent testing houses to confirm they meet these tough standards. However, rest assured, we have reports from past installations to back up our quality This includes durability under extreme conditions and resistance to various stressors like shock and vibration.

4. Customisation Flexibility

You can customise each rack to fit specific electronic configurations, sizes, and integration requirements, overcoming the limitations often found with off-the-shelf commercial solutions

5. Anti-Condensation Heating

To combat the issues of condensation, that can arise within the humid, variable temperature conditions typical in naval environments.  Our racks optionally include our own rugged built-in anti-condensation heaters to protect the electronic equipment.

Benefits of MIL-STD Racks in Naval Environments

Deploying MIL-STD racks in naval vessels offers numerous advantages:

  • Durability and Reliability: Designed to withstand the harsh conditions at sea. Including saltwater exposure, which can quickly erode standard commercial racks.
  • Operational Security: Enhanced EMI/RFI shielding protects against potential electronic eavesdropping or data corruption.
  • Customised Solutions: We tailor every aspect of the rack to maximize space and functionality. This is critical in the confined spaces aboard submarines and ships.
  • Longevity: Built to higher standards, these racks promise longer lifecycles, reducing the need for frequent replacements and maintenance.
  • Quality Assurance ISO 9001:2015: Rigorous validation, verification, and a full engineering review process to guarantee product excellence.
  • Exceptional Service and Support: At Metromatics, we take pride in our experienced and skilled team, many of whom have been with us for over a decade. We deeply understand our products, collaborate closely with our customers, deliver top-quality items, and offer dedicated personal support.


At Metromatics, we understand the critical nature of naval operations and the role that reliable electronic enclosures play. Our 19-inch Comms Racks meet the Australian Navy’s standards and proactively anticipate the demands of maritime duty.
