Zoom in closely and you can see a hole in the hull, between the sheeted areas. My guess is that they need to insert a engine or gearbox into the open space.

Gearbox going by the rumors :(

Is that common on surface ships?

I've never seen it before but it's what I was told at the Clyde.

They're a lot more visible on the picture of the starboard view posted upthread by Donald.

Some more photos, from UKDJ.

Do many other surface ships feature acoustic dampening features on the hull (the black area with a matte texture) like the Type 26 Frigate does?

Seems way too early in the build process to be fixing tiles .... color me skeptical.

We all know that she will be sitting in the water for several years before going into dry dock to have the sonar fitted to the bow. And a possible repaint. Maybe they need to test the Airfix glue.

With the length of time that it is taking for Airfix to make a QEC model, I won’t hold my breath for the delivery of a T26 model. Any “Airfix Glue” that I might had would long since have gone solid. :mrgreen:

Wonder if they're the exact same type that Submarines get or if they're a slightly different design. Submarines tiles are designed to absorb sonar energy from enemy sonar and deaden sound from within. The role these would appear to fill is primarily to reduce sound from the propulsion.

Would they not be best on the inside of the Hull then...

Sure looks like tiles now they've taken the plastic off ...

Absolutely. I've not heard of surface ships being fitted with tiles before, but there was a note on the UKDJ tweet from someone that said that HMCS Montreal (Halifax Class) was fitted with tiles. Looks like she received them in her first refit period in 1997, probably as a test. 12,500 tiles fitted, but it looks like it wasn't a massive success as no further Halifax Class received them. Not sure if they're still there (probably unlikely after 20 odd years if they weren't successful), and I can't find any imagery of them.

So presumably the situation has changed if the RN thinks they're now worthwhile...given that the machinery in a T26 has every quietening measure possible already installed (at enormous cost), perhaps this is the only way to reduce radiated noise further.

Any reason to put the tiles on now rather than when she is being fitted out in Scotstoun in dry dock?

I take no stance on what's going on with T26, but an acoustic decoupling layer is most effective outside the hull, and an anechoic layer is only useful outside the hull. So acoustic tiles, whether optimized for one or both, are always outside a hull.

BAe has now finished risk mitigation study of possible Indyref2. MoD will not allow non UK shipyard to build 'warships'. As a result options are now being prepared to move up to 800 jobs in design and advanced material research/manufacture to CL and Barrow. They are also now looking at an all England/Wales supply chain to prevent similar disruption. These changes will come into force if a second referendum is announced or if a wildcat referendum takes place.

My only guess is that they needed to be attached under cover and as the hull won't be undercover again, they had to do it in the shed.

Or maybe Bob with a tube of glue in his hand needed to be kept away from curious eyes (and cameras) :D :D

Not surprising and not good news either :(
