The first Type 26 frigate from BAE Systems for the UK is coming together. Check out the video of the HMS Glasgow being rolled out of the build hall on April 29 and then joined with the forward block. After these two sections are welded together, the hull of the HMS Glasgow will be structurally complete.
As you can see in the video, joining the super blocks is a precision operation. Welding does not denote a weakness in the ship structure, but can be as strong as the rest of the metal if done correctly.
The Type 26 design is also selected by Canada for the future 15 Canadian Surface Combatants that will be built at Irving Shipyards in Halifax for the Royal Canadian Navy.
