A joint venture between Hunting Engineering and AEA Technology has submitted a bid worth about £70m for equipment to power the British Army’s £2bn Bowman battlefield communications system.
A team led by Racal Acoustics is believed to have submitted a rival bid.
Archer Communications, the Ministry of Defence’s prime contractor for the Bowman project, is expected to award the contract before Christmas.
The AEA-Hunting proposal, known as Lionheart, uses lithium-ion battery technology, which is said to offer a 35% weight saving over competing technologies and increases operating life by about four times.
This would enable use of the communications system for up to 24 hours at a time during missions.
