Submarine Matters
About subs, military/naval, missiles, nuclear weapons & politics. New Aussie subs have been just talk since 2009. Collins LOTE 2028-2040? of partial help. UUVs help more. POTUS may cancel AUKUS Virginias in 2031 as the USN needs all SSNs to the 2040s. Australian Gov ignores US higher priority to Columbia SSBNs (one/year being commissioned 2029-2041). Meaning minimal Virginia production until 2043. Shawn C and Gessler are excellent authors.

"Though early Trumpism was frequently characterized as "isolationist" due to its skepticism of nation-building and traditional alliances like NATO, the philosophy evolved toward what critics call a "new imperialism" or "nationalist interventionism". [1, 2, 3, 4, 5]

Early Singapore Involvement: Australia's "We Will Build an ICBM" Threat Yielded AUKUS Pillar 1
Singapore and Gilmore Space Technologies

Adam Gilmour (above) CEO, Co-Founder of Gilmour Space Technologies with ERIS Block 1, Australia's dual-use capable rocket. ERIS has the classic ICBM size and shape (eg. like a Minuteman III) especially in tonnage at launch. The shape also includes ERIS not having strap-on boosters that would impede each Eris being placed in ICBM silos. (Photo Gilmour Space via Byron Bay's The Echo, March 1, 2024).
[As at 2017 - Adam Gilmour an Australian entrepreneur has chosen Singapore as his base to build his own space startup and carve out a niche of his own...[Adam Gilmour's] rocket factory was located near Changi airport in Singapore,...he [Gilmour] ran an open-plan facility buzzing with activity and packed with futuristic-looking prototypes...his engineers were busy testing a new 3-D printer, which makes rocket fuel in record time. ...“We are working on low-cost small satellite launch vehicles to take satellites with masses up to 400 kilogram to orbit. This capability is matched by few other providers in the industry and we plan to be the cheapest in the market” he explained.]
---------------------------------
Australia has since the 2000s been revisiting nuclear deterrence weapon options, including long range strike platforms. ICBMs based in central Australia could hit Beijing. The dual use Eris 1 rocket at 23m tall and total 34 tonnes mass at liftoff is more than coincidently the size of a US Minuteman III ICBM at 18.3m and total 36 tonnes.
Missile carrying nuclear powered submarines (particularly versatile Virginia Block V and VI - SSGNs) could also hit Beijing and/or Shanghai with SLBMs or SL(Hypersonic)HMs.
Australian Threat
By 2022 an Australian (Aus) bargaining threat to the US was established. Unless the US and/or UK made SSNs available to Aus, Aus could build thermonuclear warheads affixed to "Gilmour" ICBMs. China being the usual potential target.
The US (the aging Biden regime, at least) reacted with AUKUS Pillar 1. The UK (SSN owning junior partner) wanted (or was persuaded) to join this deal. This is, in part, because UK nuclear powered submarine tech and Trident II missile availability to the UK heavily relies on the US.
SILEX makes Australia HEU Capable
The primary stage for an Australian thermonuclear weapon is a fission bomb which Australia could produce using the SILEX process yielding 95% HEU. This would be the trigger for a "secondary" Deuterium–TRITIUM fusion bomb.
Deuterium is extracted by separating heavy water (D₂O) from ordinary water and then isolating the deuterium gas. This is all within Australian scientific-industrial capabilities. Deuterium–TRITIUM fusion (D-T fusion) is a type of nuclear fusion in which one deuterium (2H) nucleus (deuteron) fuses with one tritium (3H) nucleus (triton) giving one helium-4 nucleus.
As a dual-use cover Australia could build CANDU (Canadian Deuterium Uranium) reactors to generate large amounts of electricity (for Aus large cities). This is while simultaneously producing TRITIUM through neutron capture in CANDU reactor's heavy-water moderator and coolant.
A major problem is the US has called Australia's nuclear bomb blackmail bluff with promised SSNs only likely to emerge mid 2040s onwards. So the US remains Australia's extended deterrence nuclear guardian. But could the likes of a Trump, Hegseth or their America First successors ever be trusted to sacrifice San Francisco to protect Sydney from "Shanghai-Beijing's" nuclear capability?
Fortunately/Unfortunately? Australia, having spent $Billions in up front deposits to the US and UK submarine industrial bases, has lost its SSN bargaining power.
This is indicated by Australia's Defence Industry Minister, Pat Conroy's only passing threat in July 2026 where he stated the Submarine Rotational Force-West (SRF-West) rotation of US submarines through HMAS Stirling in Western Australia would conclude in 2032 unless what? Delivery of the first US SSN to the RAN in 2032 was implicit. This has led to delayed SSN transfer to Australia. This may be forcing Australia to return to nuclear weapon intentions.

UK Carrier jokes: Can't even attract local escorts! No Astute thinking.
BAE is a virtual monopoly in Britain building the aircraft carriers (above) and all the submarines ie. the final Astute, SSBN-Dreadnoughts and SSN-AUKUS.
---
- finds the carriers break down too often
- Britain's decision to only have the ski-jump/vertical takeoff F-35Bs means the F-35Bs have low fuel/range, low weapons' load with F-35Bs being the Only fixed wing types
- in contrast US and French CATOBAR carriers (the French carrier being far smaller than Brit carriers) can operate more aircraft, with more fuel, range and weapons and can also operate fixed wing ASW aircraft, unlike Brit carriers (restricted to short range, short loiter ASW helicopters).
- hence must rely on 2 or 3 foreign escorts to make up the numbers in a carrier group
- frequently finds all Britain's Astute SSNs are under medium-longish term unscheduled repair
- hence a British carrier group must rely on an essential US or French navy SSN to defend the group

USN said it needs 66 SSNs: Today only 32 SSNs fully operational/available
- Operational (Available for Duty): Approximately 31 to 32 submarines are fully operational or available for training and deployment.
- Virginia-class: 26 operational/active hulls
- Los Angeles-class: Approximately 21 hulls (following recent drawdowns and retirements like the USS San Juan in mid-2026)
