The refit of Swiftsure was expensively slowed, when the hull was discovered in early 1958 to have compressed more than 18 inches under the weight of a new bridge, there were many stanchions fitted internally below the new bridge to prevent further collapse of the structure, which was similar to that fitted to Belfast, and intended in both cruisers to allow the fitting of data links to the carriers and an operations room which would have included screens for the new Type 965 radar and Type 184 sonar requested by the RN staff in 1957 for Swiftsure and Superb.
