Top Line

• US Treasury Secretary Bessent says a deal to reopen the Strait of Hormuz could land within days, as Washington concedes it is "virtually" out of key interceptor missiles. Northrop Grumman has signed $3 billion in multi-year munitions deals to lift interceptor output, a clear read on how deep the magazine problem runs.
• Chief of the Defence Force Mark Hammond says US nuclear-powered submarines will have "enduring access" to HMAS Stirling, likening it to America's WWII presence and cutting against the government's five-year framing.
• The US Navy is reclassifying 19 Virginia-class boats as guided missile submarines carrying 40 Tomahawks, taking over the retiring Ohio SSGN strike role and lifting the firepower of the class Australia is buying.
• The 2026 Defence Innovation, Science and Technology Strategy names Ghost Bat, hypersonics and directed-energy weapons as priorities.
• AFP, ASIO and Victoria Police are hunting a far-left group over an arson attack on a Melbourne defence manufacturer.

Watchpoints

• Watch whether a Hormuz reopening holds past the first week, because a durable deal is the only thing standing between depleted US interceptor stocks and a hard conversation about where Australia sits in the allocation queue.
• Northrop's $3b in munitions deals signals the US is buying capacity rather than just rounds, so the question for Canberra is whether Australian guided weapons and explosive ordnance facilities get written into that expansion or watch it from the sidelines.
• Hammond's "enduring access" line at HMAS Stirling has opened a gap between Defence's operational reality and the government's five-year framing, and that gap will be exploited in Parliament and in WA long before Submarine Rotational Force West stands up.
• The 2026 DIST Strategy names Ghost Bat, hypersonics and directed energy as priorities, so the test over the next two quarters is whether those priorities attract acquisition money and production contracts or remain a research portfolio with a good cover page.
• The Melbourne arson investigation marks a shift in risk for suppliers, and expect security compliance costs, insurance premiums and site hardening requirements to start appearing in tender conditions for smaller primes and subcontractors.
