BAE Systems press release
The largest surface shipbuilding program in Australian defence history continues to make strong progress at the Osborne Naval Shipyard in South Australia.
Shipbuilders are initially manufacturing prototype five prototype ship blocks to test and refine the processes, systems, tools, facilities and workforce skills ahead of construction of the first Hunter class frigate.
There are 22 blocks in each Hunter class frigate. The first prototype block, known as Block 16, weighs more than 140 tonnes and its construction involved the expertise of 35 different trades, including engineers, boiler makers, welders, fabricators and project managers.
This first prototype block (without any Hunter-class design changes) would form part of the middle of the ship where there are accommodation spaces.
Over the coming weeks and months, the Hunter program will continue constructing the second and third prototype blocks, each more complex than the last.
In mid-2023, the prototyping program will commence the production of additional blocks incorporating the Hunter-class design changes, with these blocks actually being used in one of the first three ships.
“Throughout construction of the first prototype ship block, our highly-skilled workforce has been able to incorporate new, more efficient and effective ship-build methods and innovations into our processes. Already, the quality and productivity we are achieving is well above where we thought it would be at this stage of prototyping. This quality demonstrates the potential of a strong future for continuous naval shipbuilding in Australia. We are working towards achieving new benchmarks in manufacturing efficiency and quality and the new processes we are developing allow much greater engagement with Australian suppliers.”

Block 16 specifications:
- Weight: 141 tonnes
- Comprises: 4 steel units, known as UB24, UB24B, UB34 and UB34B
- How they became one: UB24 and UB24B were constructed into a half block, and UB34 and UB34B were constructed into another half block. Both half blocks were horizontally constructed to form one prototype block
- Size: 452 square metres – equivalent to 2.5 average-size Australian homes
- Length of time it took to construct: 45,000 hours (cut steel was December 2020)
- Number of trades involved: 35, including engineering, boilermaking, fabrication, project management and construction
