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 40 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.
