Ruggedised equipment for land, sea and air

Reliable specialised military and commercial communication systems.


Petards Defence Services is a recognised authority in the design, build and post design services support of rugged military specification and commercial communication systems for airborne, maritime and land applications, including:

Bespoke hardware solutions 

Our team of experts also develop hardware solutions for use on military platforms, which meet the relevant standards for Environmental, EMC and where required TEMPEST approval.
Previous projects include:

TEMPEST housing for computer systems

Used on Royal Navy surface vessels and Astute class submarines (Datalink application).


A fit, form and function replacement display for the RAF Sentry E3D fleet. The display had to meet the space envelope available for the original CRT display and interface with the graphic protocols generated by the on-board radar console graphics system. The displays, which were certified to the relevant airworthiness standards, provided a significant improvement in performance and were later fitted to the French Air Force AWACS fleet.
