Part One | Ukraine demonstrated what happens when one side controls the electromagnetic spectrum and the other does not, and Britain’s forces, highly networked and deeply dependent on the spectrum for everything from GPS navigation to encrypted communications, cannot afford to ignore the lesson.

Ukraine’s experience offers a clear message for the defence industry: battlefield testing is not a badge to collect, but the start of a demanding process of iteration, partnership and operational learning – adapt or lose.

The start-up says it will combine a containerised launcher, off-the-shelf components and a proposed UK assembly facility to challenge long development cycles in defence.

Voyant has shown the UK Ministry of Defence (MOD) that its navigation software can keep an uncrewed vessel on course without satellite positioning, a significant advance for autonomous maritime platforms expected to operate where GNSS signals are unreliable or under attack.

So reports are coming out on the seven vehicles that have been selected to go through to the next round of assessment for the LMV contract. The only two all British contenders, Fering and Portsmouth Aviation, seem to be out and a surprise contender from Spain appears to be in, the Iturri.

UK company, Alpha 56, says its work grew from a field communications problem: getting reliable connectivity and data-sharing equipment to users operating beyond conventional infrastructure.
