The defense contractor’s Australian arm told Defense News that it has issued a request for quote to industry.
Australia’s defense department awarded Lockheed Martin Australia a potential $565.7 million contract in January to help design, build and integrate the submarine combat system.
Lockheed is the combat systems integrator for the $39 billion submarine program.
Thales Chairman and CEO Patrice Caine told reporters Tuesday that he expects Lockheed to name a sonar technology supplier by 2019.
France-based Thales aims to win the sonar subcontract, which Defense News estimates will bring in nearly $1.2 billion in sales for the company.
