Missile technology is a key indicator of a nation’s independence and defense readiness. However, in the Commonwealth of Nations, missile development is heavily reliant on U.S. technology and strategic partnerships.
The British nuclear deterrent relies heavily on U.S.-manufactured Trident II missiles, which are deployed on Vanguard-class nuclear-powered submarines. The UK’s only remaining nuclear leg is its sea-based arsenal, which is underpinned by American production. The United Kingdom also uses the Storm Shadow cruise missile, a joint Franco-British weapon, and Tomahawk cruise missiles, which are developed by the United States.
Australia’s military modernization is significantly shaped by the AUKUS agreement with the U.S. and the UK. While the country continues to depend on foreign systems, such as the Harpoon and Naval Strike Missile in the Royal Australian Navy, it is acquiring advanced weapons through this alliance. The future of the defense strategy is also influenced by the potential deployment of hypersonic weapons on its nuclear submarines.
Canada’s defense approach centers around its role as a member of NATO and NORAD. It plays a supportive role in air and missile defense, without developing its own cruise or ballistic missile systems. The Harpoon system, though outdated, is currently the most powerful missile in use, and any upgrades will likely come from foreign procurement.
New Zealand’s unique position involves its focus on space technology rather than offensive missiles. The country has successfully launched satellites with its Electron rockets, which demonstrate its ability to build advanced aerospace systems. However, due to its pacifist values and isolation, New Zealand has no offensive missile capability.
The article emphasizes the varied roles and strategic positions of the Commonwealth nations in the missile landscape. Their reliance on U.S. technology highlights the broader reliance on alliances, which is central to their national security strategies.
