Space weapons are the logical progression in the increasing militarisation of outer space. As the landscape of space exploration adapts to the new space economy, both outer space and space weapons are more readily available to a broader range of actors. Space wars are an increasing possibility with which international law must grapple. This article explores whether the legal framework is fit-for-purpose in addressing the potential weaponisation of outer space by reconciling the relevant space law and disarmament principles, including international humanitarian law. The analysis ultimately highlights that cumulatively applying different laws to the new space economy produces lacunae in the regulatory regime. As a result, current international law is unable to prevent the weaponisation of outer space. The most critical gap concerns the testing of debris-causing space weapons. The article then considers the New Zealand (Aotearoa) context, using Rocket Lab as a case study for the role of domestic space law in the new space economy. Domestic space legislation fills some of the gaps in the legal framework. However, Aotearoa's flexible approach to risk management leaves the issue of space weapons to Cabinet guidelines, which lack sufficient legal force. Moreover, Aotearoa's space activities include satellite launches for foreign militaries, which exacerbate the conditions for the eventual weaponisation of outer space. Satellites improve national security by employing offensive or defensive military capabilities, yet states cannot determine their genuine intent, partly due to the enmeshment of military and commercial activities. The uncertainty of intent incentivises space actors to protect their assets by developing and using space weapons. Thus, the law must evolve to address space weaponry proactively in times of peace before conflict spreads to outer space. [ABSTRACT FROM AUTHOR]
