Serco Asia Pacific has welcomed Serco Group’s acquisition of the Naval Systems Business Unit (NSBU) from Alion Science & Technology in the US.

NSBU is a leading provider of naval design, systems engineering, as well as production and life cycle support services to the US Navy, US Army and Royal Canadian Navy. NSBU employs around 1,000 people and helps defence forces design, maintain and support their ships and submarines.


This acquisition extends the global capability and scale of Serco's defence business, which includes a history of supporting Australian Defence Force maritime vessels around Australia.

Serco Asia Pacific chief executive Mark Irwin said the acquisition added to the experience and skills that had been developed in Australia over the past 20 years.

"We look forward to continuing the ongoing support we provide the Australian Defence Force and welcome this new capability that has been added to our Group Defence program, which can be utilised across all our jurisdictions," Irwin added. 



Since 1997, Serco, through the Fleet Marine Services contract, has provided flexible and cost effective maritime vessel operations, with a qualified mariner workforce to meet the needs of the Royal Australian Navy.

Serco is currently one of Australia’s largest maritime service operators and combines people, assets and systems to deliver optimal vessel operations, managing and operating 800 maritime support craft for the RAN.

Alion engineers solutions for the US Department of Defense across our six core capability areas, which include: 

  • Artificial intelligence;
  • Intelligence, surveillance and reconnaissance;
  • Modernisation and sustainment;
  • Networks and software;
  • Systems engineering and integration; and 
  • Weapons platforms. 

Serco provides critical support services to defence organisations, operating both in-country and embedded within deployed forces around the world. We have deep expertise operating across all military settings, including space, marine, land and air.
