This pic shows the planned development for the Osborne site. The olive green buildings are existing and the white buildings (& grey paved area) are planned to be built.
The large green shed on the left is where final construction of the Hunter/Type 26 Frigates is underway (capable of two side by side) with further buildings not shown where sections are assembled. The surface ship building area is known as ASC South.
The slightly smaller green building leading to a ship lift is where the, now cancelled, Attack class submarines were to have been built and is the site where the Collins class were originally built and now have their 2 year Full Cycle Docking (every 10 years). This is where ASC North (submarine) starts and will be expanded very significantly.
Those buildings will give a reference for the size of all the planned buildings. It is a massive area of land and, when it’s complete, it will be a very modern, digital, parts manufacturing and submarine assembly complex. The final assembly hall is on the right side adjacent to a very high capacity ship lift. The area is considerably larger than what is in use at Barrow.
The unused section in the middle is the Mutton Cove Conservation Reserve which is off limits to any development.
