Personally I think one of the biggest shames for the RN was that they didn't manage to proceed with the Maltas.  They were quite different to the previous British carriers in that the hanger and flight deck were superstructure and not part of an armoured box so likely would have been easier to convert to an angled deck configuration than the armoured fleets were.  Their size was not that different to the Midways but I believe they had higher freeboard which would have been a bonus.

Idealy the UK would have continued the Maltas and second batch of Centaurs in slow time or even suspending, but not cancelling them, while accellerating the completion of the Audicious and first batch of Centaurs before completing the Maltas and the "Hermes" to a modernised design from the mid to late 50s.  The incomplete Colossus and Majestics would sold or scrapped, the completed ones sold or transfered.  I even had the idea (quite improbabe that it would ever happen) that a number of the Colossus and Majestics could have been transfered to the USN as CVS and / or (alternatives to the converted Essex) to offset the UKs Lend Lease debt, a win win in that the USN gets a perfectly capable but much more economical platform for the CVS role.

Legacy carriers, specifically the four materiely sound armoured fleet carriers would be transfered / sold as soon as the Audicious and Centaur class ships were available, with Illustrius and Formidable scrapped.  The nations acquiring the armoured fleets and Colossus and Majestics would be possible customers for the Audacious and Centaurclasses, with or without modernisations.

HMS New Zealand:  Becomes HMCS New Zealand

Kiwiland doesn't get a carrier? ??? ;)
Errr...typo on my part.  Was supposed to be HMNZS New Zealand.  Though it would be partially staffed by current/ex-RN staff...

BuShips 1955 self-protecting CVAN

While a reversal of what the design seems actually intended for (vertical-takeoff interceptors and a smaller number of CATOBAR bombers & night fighters), I like the idea of using Vertijets as a backup in the event of total catapult malfunctions (because I like that World Navy aircraft carrier in Thunderbirds), and I like the Shipbucket graph author's use of the Ryan Model 115C instead of a pure Vertijet, if only for the possibility of conventional, arrested recovery- in fact, Vertijet-style landing on a ship is too much for my ameteur mind to comprehend  ;D

So much detail in such a small scale.

Is anyone aware of any of the navies that operated the Majestic-class aircraft carrier ever studied/considered incorporating a 'deck-edge' aircraft lift in place of the aft 'mid flight-deck lift', so as to not inhibit flight operations?
Would such a 'deck-edge' aircraft lift be obtainable in terms of engineering, in the case of a major refit?

With enough time and money, just about anything is possible. Is it likely, though, is the question.

Given the small size of the ships, weight and balance are critical things and hanging a 60's era fighter/ASW aircraft out on a heavy elevator at maximum distance from the centreline isn't going to be a trivial thing. Being so small, there are few places to put an elevator that don't get in the way of operations and can be managed from a balance POV. Possible one elevator just forward of the island and one on the port side right aft. The aft elevator would be unusable during recovery and the fwd elevator might be unusable during cat shots. Which is not too different that the arrangement with the CL elevators, which may be why they weren't moved in the first place.

To move them would mean a reasonably substantial rearrangement of the internals of the hangar deck plus making structural access out through the sides of the ship. Again., doable, but not trivial and, given the commercial nature of these ships' design, possibly structurally unsound.

But, as the song says, if "you got the money honey, I got the elevators" or words to that effect...

Thanks for your informative reply tankmodelet!

Very interesting perspective, which makes sense. I've got something in the works with jonesthetank, and it just crossed my mind - 'did any of the operators of the Majestic class consider such a modification, considering the longevity of the design, which ironically were designed and build for a life expectancy of what 3-years. 😯
Any how, was hoping such a practical modification/application (Iwo Jima class LPH type elevator for example) might have improved flight operations and tempo .....

No point asking about the feasibility of substituting gas turbines for their boiler power plant then 😬

Thanks again

😂😂You mean I haven't broken your mind yet Mark?😂😂

Believe it or not, I dreamed of this conversation/modification the other night! I put it down to the flu I've been suffering, obviously making me somewhat delusional, as I have to admit, I much prefer dreaming of beautiful scantily dressed woman serving on the mortar line!!😯

But alas Mark, this modification to the Majestic-class doesn't sound practical or cost effective 😩

I'll hopefully email you tomorrow, if that's ok?

Hi Rob,

I think changing the drawings of HMAS Sydney or Melbourne would be easy, but I suspect in the real world the effort of the conversion to deck edge lifts would have bankrupted the RAN if not the whole of the ADF!

Yes, probably be easier to acquire a complete new carrier.  I could only see such a mod going ahead if there were no other options and even then it would be questionable.

The technical feasibility of changing the steam turbines for gas turbines is probably easier than the elevator question. The financial feasibility is worse, however.

Technically, you gain in economy, manpower requirements and especially internal volume in the engine room. You lose in needing to add significant air intake and exhaust/cooling and heat recovery exchangers and, in the balance, you are significantly ahead, to be sure. But, financially! Hoo, boy, is it expensive. It could only be done at a major refit and, from a timing perspective, probably should be done when an angled deck was added, it's that level of major change. But the angled decks were added 10-15 years before effective naval gas turbine systems were available.

Still, if you were doing it, you'd need to open up the ship, right down to the keel, pull out boilers, steam turbines and recuperators, install gas turbines, new much larger airways (in and out) and new higher efficiency recuperators. New stacks, rejig the island to manage that, new bunkerage, piping and pumps to manage the lighter crude/kerosene used for naval gas turbines and then reallocate the interior spaces to use the volume you free up from eliminating the boilers and all the steam trunking.

You's still need steam generation capability, though, if you keep the cats. And that may be why the US went from oil fired steam turbines to nuke steam turbines. Simply because they absolutely needed steam, anyway, to run the cats.

If steam cats are retained it simply may not make any sense to delete the boilers. If you switch to pure helo ops or VTOL/ski jump ops, then going to gas turbine may be useful. The Brit Invincible-class carriers are all GT powered and none have ever had a cat.

Sounds like it would be easier to build a new ship design from the keel up.
