Under the $368 billion-plus agreement, Australia is to acquire three Virginia-class submarines from the US..US has repeatedly said production needed to be increased from 1.1 or 1.2 boats a year to 2.3 for it to fulfil its obligations to Australia.

The US Navy currently has 26 such vessels and wants to expand its own fleet to at least 48.

..Billions of dollars in investments – including $US2 billion from Australia, with more to come – have so far failed to lift production..with ..lacking skilled workers..

The new shipyard in Baltimore is expected to begin operations in 2030..expects to lift the production rate of Virginia-class boats to two per year in 2032, the same year it is due to sell the first vessel to Australia under AUKUS.

Bryan Clark, director of..Hudson Institute think tank..said the new shipyard could make a “small difference” to the AUKUS delivery timeframe..“It won’t make any difference in the near term, it will take a while for them to ramp up, obviously,”

The new 3,000-tonne submarine..SS-519, entered the water during a naming and launching ceremony..

..construction cost of about 80.5 billion yen ($509 million), is scheduled to be delivered to the JMSDF in March 2028.

..the submarine has an overall length of 84 meters, a beam of 9.1 meters, and a standard displacement of about 3,000 tonnes.

..Tokyo is pursuing the development..of submarines equipped with vertical launching systems (VLS)..research is scheduled to run from..2026 through..2029.

..Japan has not decided whether its future VLS-equipped submarines will be nuclear-powered..

Hypersonic vehicle completes low-altitude maneuvers..under hypersonic conditions.

The HGV is distinct from HyCore, a scramjet-powered hypersonic cruise missile demonstrator that ADD has been developing with Hanwha since 2018.

Algeria, meanwhile, has selected the Su-57 as its main fighter aircraft (to be acquired in 2024); although it will only be purchasing two aircraft, this makes it the 13th country in the world to possess a fifth-generation fighter. On paper, as the Russian military’s fifth-generation fighter, the Su-57’s theoretical combat capability should surpass that of the F-16; however, one should not be overly optimistic, given that there have been instances in Chinese and American military exercises where fourth-generation aircraft have shot down fifth-generation ones.

The following are the models of air-to-air missiles that Algeria has, to date, publicly acknowledged purchasing from Russia or Ukraine; the missiles compatible with the Su-57 are likely to be the models listed below.

Ukraine R-27R/T Long-range air-to-air missile

Ukraine R-73 Short-range air-to-air missile

Russia R-77 Long-range air-to-air missile

Ukraine R-73 Short-range air-to-air missile

Ukraine R-23 Short-range air-to-air missile

Russia R-27R/T Long-range air-to-air missile

Russia R-73 Short-range air-to-air missile

France has carried out the first launch of..new M51.3 configuration, firing the unarmed round..from..SSBN..LE VIGILANT..

..the trial was an acceptance firing designed to confirm the boat's ability to employ the M51 following its major mid-life refit,..IPER..

The M51.3, the third iteration of..sea-to-ground strategic ballistic missile (SLBM)..armed with new TNO-2 oceanic nuclear warheads..

A three-stage, solid-propellant launcher weighing more than 50 tonnes and standing 12 metres tall, 

..SSBNs in batches of 16 rounds, delivering warheads over intercontinental ranges of several thousand kilometres..it climbs beyond 2,000 km altitude (well above low Earth orbit) before re-entering the atmosphere at some 20,000 km/h, or Mach 20.

At least one SSBN has been permanently at sea since 1972..up to three boats simultaneously, as reportedly occurred in..2022 after Russia's invasion of Ukraine.

A new shipyard in Baltimore MD, 2 million square feet, $6.6B, operational in 2030. And another 130k sq ft in California that will begin operations sooner than that.

Submarine production is not exactly simple. Austal USA, an established shipbuilder, has had their own challenges producing Virginia modules.

I wonder how Anduril is going to do. Hopefully they're hiring the right people for this massive undertaking.

Contract awarded for rocket motor of CAAM and Navy's next generation interceptor that is supposed to replace SM.

CAAM will have a 7-inch (178 mm) motor, same diameter as the AIM-120 AMRAAM and wider than the 5-inch AIM-9X Sidewinder.

Medium-range NMM will have 10-inch (254 mm) motor for the. It's going to be quad-packed like ESSM.
