What we do

GRiD Defence Systems comprises a team of engineers with extensive knowledge in the design and manufacture of military hardware.  All of our products are built to survive the harshest environments whilst maintaining quiet EMC profiles and full environmental qualification.  Each product is configurable and is tailored to include the connectors, interfaces and expansion cards required to suit each individual customer specification.  This MOTS (Modified Off the Shelf) approach allows our hardware to be integrated onto both new and established platforms without the need for bulky expansion boxes or unnecessary additional peripherals.

We believe that the most successful hardware solutions are born from a close, open relationship with our customers.  Our consultative approach allows for continued input from customers from the start of the project until product delivery.
