BAE Systems Australia has won a five-year, A$89 million (£43m) contract extension to maintain the periscopes of the Royal Australian Navy’s Collins-class submarines.

Under the terms of the deal the firm will provide maintenance and support for 16 periscope systems at the firm’s Mawson Lakes factory in South Australia and at HMAS Stirling in Western Australia.

The work will extend into the 2030s and involve overhauling and recertifying the attack and search periscopes on all the boats in the class, as per a recent company press statement.

BAE Systems Australia Managing Director of Defence Delivery Andrew Gresham commented: “BAE Systems Australia is a long-term sovereign capability partner to the Royal Australian Navy with more than three decades of expertise in the manufacture and build, sustainment and upgrade of Collins-class submarine periscope systems.

“We are delighted to confirm a five-year contract extension, building on our large body of work with the Submarine Enterprise that ensures the continued operation of the periscope systems, which are critical for the Collins Class fleet.

“Today’s announcement underscores the importance of our company’s long-standing experience in delivering periscope systems in Australia and our local network of trusted industry partners delivering into the sustainment programme.”
