NBC - Naval

At sea warships are increasingly likely to be subjected to attack by Nuclear, Biological and Chemical (NBC) agents. In order to maintain full operational capability, a Collective Protection System (CPS) is required.

Portsmouth Aviation Limited is a significant defence equipment design and manufacturing company founded in 1929 and we have over 20 years experience in the design and manufacture of NBC Air Filtration Units (AFUs). Over this period, we have been the supplier of NBC AFUs for the ships of the Royal Navy and the Royal Fleet Auxillary.

We have the experience and the expertise to:

• Advise on the generation of specifications for ship NBC collective protection systems and to provide draft statements of work to assist end customer procurement action.
• Recommend the optimum type and arrangement of NBC AFUs for any vessel.
• Work with ship builders and ventilation system suppliers on the installation and setting to work of NBC AFUs in new build vessels.
• Design retrofit installations for ships already fitted with NBC AFUs so as to upgrade them to the latest NATO standard of radial filter installation.
• Design decontamination compartments for new vessels and work with ship builders on fitting out and setting to work.
• Provide freestanding decontamination and air lock units for vessels for retrofit.
