Global Defence

Specialists in the field of naval power conversion and distribution, we have equipment in service on virtually all of the Royal Navy’s submarine and surface fleet. Supporting equipment supplied over 80 years ago which is still in service is a testimony to the integrity of our designs and the high build standards that we have attained.

Many of our designs distribute power with battery support. This theme of supporting critical on board functions such as weapons, emergency communications and lighting – often after all other sources of power have been lost – indicates the critical importance of our equipment to the vessel and its crew and the role that we play in supporting so many of the world’s Navies over the years.

Our products are ruggedised to meet high levels of shock and vibration, engineered to be fully compatible with ship or submarine electrical systems and are built from the ground up for deployment.

Survey, Test and Repairs

We offer a full strip and survey service for all our products.

A survey report of our findings and our recommendations for repair will be supplied.

Some of our equipment has been in service for over 50 years but we are still able to support most repairs.

If items have been found to have ‘No Fault Found’ or we have been able to repair during the course of the strip and survey activity due to the simple nature of the fault(s) and the associated low cost, no further costs will be incurred.

In the situation where equipment is obsolete depending on the fault we may not be able to repair, this will be investigated on a case by case basis.

For assistance please contact our Sales Team.
