Can someone explain why the stern deck of the Canberra class ends at the lift? Seams like a waste of a fair amount on deck space.

With its location the lift aft is able to lift oversized helicopters not limited to the size of the lift, i.e., part of a helicopter hanging over the lift's edge... This can't be done with the forward lift... There are helicopters in the world that are larger than a NH90, i.e., larger than the size of the lift... One never knows what the future will bring either... Isn't it a good idea to design the aft lift with this in mind?

Given a choice, I would think it more sensible to have a lift with helicopter overhang located to port of starboard of the deck, instead of after. Perhaps that is just me though.

i was under the impression they dont fit in the hangar...
Nah, on the promotional videos showcasing the LHDs and how "great they are" it has models of the LHDs with model helicopters inside. These helicopters are Chinooks, there are also other graphics showing the interiors with Chinooks inside.

From memory I think it was one of the things they tried to sell the design on, the ability to fit chinooks into the hanger without having to remove the rotors first. Feel free to correct me if i'm wrong though. :p:

You are not wrong, the CH-47 fits in the hangar, by just a couple of inches :el but once in the hangar you get more room.

And talking about the rear lift issue, its designed that way because it was founded to be safer operating with the heavy things like Chinooks and Ospreys , and in terms of desing there is no missing deck, it was the rear hull that was redesigned in order to provide that extra space.

I thought they have to remove the rotors (atleast 1 set) on the chooks. Its only the smaller stuff they can keep the rotors on.

Edge lifts seem to have issues in big season things smaller than supercarriers.

Correct me if im wrong but arn't we getting new Chooks (Foxtrot models?) and they come with folding rotors?.

I have no problem with the flight deck not extending right to the stern. It provides room for weapons,decoy's, cranes and other various bit's and bob's that would interfere with flight ops if they where on the aft end of the flight deck, and make that space unusable anyway.

Nope no folding rotor set for H-47 yet. Though Boeing have designed it for the SABR offer to the Royal Navy (SABR program has been cancelled). The rotor blades have to be removed but its not such a big deal. With the size of the LHD's flight deck once the ship is offloading the amphibious force the helicopters will all stay up top unless they need to go below for maintenance.

Its also how the ship was designed. Weight management is far more important for a ship than a smooth outer mould line. The LHD has no shortage of flight deck space and isn't going to be trapping tacair over the back. Aircraft landing on will come alongside about amidships and then hover sideways and then down onto the deck.

We were told LB HMAS name today, the skipper let it slip.
No surprises really :D
HMAS Largs Bay? My new SRP initiative. Save money by not having to repaint the name on the ship!!!

With defence costings, that's probably $500,000 right there...

:D

To be truthful, and some what old fashioned...... only change a name when you have to so LB................ but JB is probably better odds.
I would put my odds on HMAS Westralia. A minister of defence from West(ern Aust)ralia the name given to the last ship we got off the UK to cover a force structure gap and a former LSI in WWII...
