HALO employs passive acoustic location techniques to detect the source of artillery fire at ranges of up to 30 kilometres. It is said to be virtually immune to countermeasures and can provide almost instant data on hostile firing positions.

The HALO battery is a 24V, 80Ah battery based on Lincad’s LIPS 6, and is engineered to the highest mechanical and environmental specifications, to provide a robust and reliable power source.

Peter Slade, Lincad joint managing director, said the awarding of the contract is another win for the company's offerings for the defence industry.

"Lincad has a long and successful record of providing specialist batteries for military applications. We’re delighted to receive further orders from Sojitz in Japan, demonstrating the quality and value that we can offer to international customers," Slade said.

Lincad specialises in lithium-ion battery technology, a technology gaining traction in Japan's defence operations. The nation's next generation Soryu Class diesel-electric attack submarines will be equipped with lithium-ion batteries.
