Australia and the UK are joining forces under the Copperhead Project to develop next-generation, low-cost guided weapons. The arrangement, signed in February, brings together both nations’ defense technology agencies, with the UK first revealing the collaboration in April and Australia following suit this month.
The project merges Canberra’s Sharktooth lightweight missile system, which can rapidly swap out key components, with London’s Modular Weapons Testbed. Together, they aim to deliver a field-reconfigurable “plug-and-launch” technology, capable of being quickly adapted to meet shifting operational needs.
The push for Copperhead reflects the increasing demand for modular munitions, particularly in scenarios where flexibility and rapid response are essential. Current alternatives like the US-made JAGM and Europe’s SPEAR missile offer modular features but remain expensive and slow to field.
By contrast, Copperhead is envisioned as a faster, cheaper, and more versatile option, designed to strengthen deterrence while providing allied forces with a scalable battlefield solution.
