The two new aircraft carriers commissioned by the MoD are being fitted with a secure fibre communications network fitted by outsourcer Capita and cable firm Brand-Rex.
The Aircraft Carrier Alliance is a consortium of lead suppliers consisting of BAE Systems, VT, Thales and Babcock. They are responsible for the delivery of HMS Queen Elizabeth - named by the Queen last week - and HMS Prince of Wales.
The two new vessels are being built in five sectional modules that will use specialised, recently developed ducting to carry the fibre - 3mm Bloite+ Miroduct. This is capable of blowing single coated fibres up to 300 metres through the "tortuous" route of bends and twists that the installers will encounter, said Capita.
"We are ensuring this important project remains on track and delivers a wide range of benefits, including substantial flexibility and future-proofing to allow use of newer technology fibres when they become available," Capita said.
There will be 100 km of blown fibre duct used across the ships, with 20,000 LC fibre terminations. The fibre infrastructure will support all tactical, navigation and IT systems.
