What remains of the Royal Navy's naval architecture department

Does the Royal Navy still have its own naval architecture department?

Yes, but it is smaller and now focuses more on oversight and in-service support than full ship design.

The naval architecture department is described as still operating from Bath. Underfunding and reduced staffing limit its ability to produce complete ship designs on the earlier scale. Naval constructors once carried out a large share of the design before yard and company teams completed it. Industry now does most of that work, while naval constructors check the designs, inspect ships in service, and provide naval architecture support.
