Google it.

From memory China's is a home built design, based on the Russian carrier they bought a few years ago.
USA are Ford class.
Indian one is similar in appearance to the Russian ones too, maybe designed with their assistance?
Italian one is officially a helicopter ship, but will be able to launch and recover F35B aircraft.
The Turkish one is not a true aircraft carrier either, but an assault ship which can launch aircraft.

Some say the propeller theory about the islands doesn't really hold true these days now that jet engines are so prolific.

@tespilotjim would like put the argument forward that perhaps it's still relevant. biggrin

You wait until PoW and QE connect up. Those straight deck sides are there for a reason biggrin

I heard that too. Apparently the plan is for one of them to go backwards so the island doesn't get in the way.

This has probably been asked before but, why did they build two islands? Seems a lot of extra expense and time when the US Navy seem to do just fine with one??

Several reasons IIRC, main ones being routing of exhaust gasses and seperation of air control/vessel control...

It's so the pilots don't have to associate with the sailors. Or vice versa, I can't remember which.

There's an F35 on deck of HMSQNLZ at the moment. It went tech while the ship was at sea so couldn't leave before the ship returned to port.

The plane has now been fixed and will be flying home from the deck while QNLZ is still berthed in the next day or so.

After reading your post I just chased this up. Current thoughts are that they're trying to get it sorted for a Thursday take off. I'm going on the ship tomorrow and will try to find out more and see if there's a more accurate time slot, as I'll probably head down closer to it to watch if I can.

Aerodynamics - not for the ship herself but for the downstream airwake bubble aircraft have to fly through on approach. More important for cats and traps but still relevant for STOVL. It also makes the uptake trunking from the gas turbines simpler and more volume efficient.

The twin island concept was also in the design long before the FLYCO was separated from the bridge.

There is no need to have a separate island to physically separate air operations. Distance doesn't add anything. You could run them side by side, or on separate levels in the same island.

It's to massage the air wing's ego.

So it’s like those hotels where there’s a separate beach club or VIP section?

Two funnels?

The American Carriers don't need funnels for their power plants...

But they also can't dock in a huge number of ports around the world because of that.

Found this today, while looking for size comparison info...



...HMS queen Elizabeth still showing in the CATOBAR section, with cats and traps and an angled flight deck. A good example of why the internet isn't always the best source of information or images on any subject really.

^That image made me realise india recently took INS viraat (ex HMS Hermes R12) of 1940s vintage and falklands veteren out of service. It looks like she is still afloat and going to be scrapped, we should all have a club together on PH, sail her home and preserve her.

The F-35 launch is intended for Friday, weather dependent.

Not idea on actual time yet sadly, but I'm trying to find out.
