    CVF as an LHD would be a bad idea. The best way to protect a warship is to keep it moving, and to use the dock you have to stop and flood down, very close to the enemy’s shore. Sitting duck time. Also if you add a doxk then it will consume 5,000tons of the ships displacement, ie internal volume. The capacity of the ship starts to shrink and it carries less. Admittedly on a 60,000ton design that might not sound like much but even on a ship of that size there isn’t much room to spare. Something will have to go to accomodate the dock, along with a vehicle deck forward of it. Then there is the question of troop accomodation, and again something in the existing design will have to go to fit it in. Not impossible by any means, but a huge ship impact by any measure.

    Did you want colour photos of these helicopter types or these specific pictures?

    Add to this, the recent true test of “International Carrier” with the Deployment of the Ark with Spanish and Italian planes and I really don’t see a prob here

    It was ‘Lusty’ not Ark, but point taken. The RN might not have much of a FJ force at the moment but it has always punched above it’s weight when required. Currently the two FAA Harrier sqns 800NAS and 801NAS are operating as a combined unit known as the Naval Strike Wing with a nominal complement of 12 GR7/9s (the two RAF Harrier sqns have 9 aircraft each) and I suspect this has more to do with a shortage of aircraft than pilots. Several sources have stated that they are only short of one QFI to stand up 801 to RAF standards (not vital by RN standards) and the ‘pilot shortage’ excuse was thought up to cover the real reason. The GR7/9 fleet was supposed to last until the F-35B arrives, but this has been postponed by at least six years now and at the current rate of use the existing fleet will have used up it’s airframe hours before then. Solution: reduce the numbers in the frontline fleet to eke out the airframe hours in order to stay operational until F-35B becomes available. This has meant only three and a third sqns worth of aircraft rather than four can be kept in service at any given time, hence the NSW.

    Generally even on a first flight an aircraft will have some kind of paint job, if for no other reason than for publicity photos; The only example of a fighter making it’s first flight ‘naked’ that springs to mind is the Sea Harrier FRS1 in 1978. Positive press is always an important part of any arms programme and it feels like a missed opportunity here on the part of the Russian firm. Perhaps they are used to the Soviet way, and publicity photos are still a bit strange to them unlike their western counterparts.

    Aye, it is. However, i wish the super hornets were cancelled. We should retain out F111 fleet.

    The F-111s are worn out and very expensiveto keep flying. Retaining those examples in service beyond their current OSD would not only be prohibitively expensive, it could well prove impossible to extend them anyway. To keep any kind of F-111 fleet operational to bridge the gap until the F-35s arrive might mean buying second hand airframes from the US, and by the time they were brought up to standard the F-35s would be ready anyway.

    There is at least one documented case of a Tomcat making an emergency landing aboard USS Midway, though the aircraft could not be launched again and was landed by crane after she reached port. The F 14 would have had to lighten itself for the landing (jettisoning all stores and tanks) as the tomcat was officially to heavy for regular ops from the Midways. In a similar incident in the 60s a USN F-4 made an emergency recovery aboard HMS Victorious but could not be relaunched and was later landed by crane and lighter.

    The CVA-01 class would have had 250ft BS6 catapults very similar in power to the current USN C-13s, so Tomcat and Hawkeye ops would have posed no problems.

    A faulty fridge does not constitute ‘Falling apart’ by any measure. The Invincible’s equipment breakdown rate is not significantly higher now than it was when they were new back in the 80s. They have been exceptionally well maintained during their lives and all three have spent long periods in reserve followed by extensive refits to return them to service. For their age, they are relatively ‘low mileage’ compared to other nations warships of similar vintage and have plenty of life left in them.;) 😀

    Hermes is generally cosidered to be able to operate up to thirty harrier sized aircraft as well as a few helos. In her fixed wing days she operated around 10-12 Sea Vixens, 6 Buccaneers, 4 Gannets and six wessex. The Vixens and Buccs were a lot larger than any of the Harrier family even when folded.

    Minas Gerais and Karel Doorman were modernized and fitted with steam catapults in Holland… the others were all done in Britain.

    Perhaps the Dutch were willing to look outside the “normal supplier” and consider another option.

    The fact that Karel Doorman was fitted with a new, longer BS catapult during her second modernization (becoming 25deMayo), indicates that the Argentines felt the MS cat was underpowered for future aircraft?

    I am guessing that KD was fitted with an MS cat also… but since she was modernized before MG, maybe not?

    The ‘longer BS catapult’ fitted to Karel Doorman was installed at her first modernisation, in 1955-58. It was most likely refurbished in 68-69 prior to transfer but certainly did not ‘grow’ in length. I have a number of photos of the ship in Dutch service to prove this.

    Great drawing! Also known as the ‘reverse angle carrier’, a variant of the SCS/VSS. If only the US had put these into production in the 70s then there would have been several customers overseas, eg Australia, Canada, Argentina, Brazil, India.. Not saying they would have recieved them but they would certainly be interested. ‘If you build them, they will come… and buy!’

    Probably correct, apart from Albion and Bulwark never had Steam catapults (BH3 Hydraulics only, also fitted to Centaur from completion in 54 until her 57-58 refit when BS4s fitted).

    Having just read a translation of the wiki article, it claims that Veinticinco de Mayo’s catapult was sold to Brazil in the 90s for the Minas Gerais to allow her to operate A-4 Skyhawks. As the latter’s catapult remained the same length to the end of her days the Argentines could only have sold 3/4s of it if at all! more likely they sold more mundane parts from below decks and not the catapult itself. Also parts from her engines and boilers would have been useful in keeping the Brazillian ship in service so long, and this may have been part of a deal to allow Argentine naval aircraft (Super etendards and Turbo Trackers) to carry out deck landing practice from the Brazillian carrier. The Super Etendards were limited to touch and goes due to catapult limitations on the Minas Gerais, though this is not a problem with the Sao Paolo which in her previous life operated etendards regularly, from her two 151ft BS5 catapults. Veinticinco de Mayo most likely had either a 145ft BS4 or a 151ft BS5, given the period when it was fitted (1955-58) I would lean toward the former.

    It looks like the Principe de Asturias because it is! The Spanish bought the plans from the US and ‘tweaked’ them with a bow ski jump, enlarged bridge with flagship facilities and Spanish CIWS. The design was later further modified to produce the Thai Chakri Narubet.

    HMS Warrior/ARA Independencia never recieved a steam catapult of any type, retaining her BH3 to the end. It was uprated to launch heavier aircraft than the other light fleets in her 55-56 refit and this was intended to be the prototype refit (partial angled deck, lattice mast, new radars, uprated hydraulic catapult) for the remaining members of the class in RN service, ie Ocean, Glory, Theseus, Triumph and Vengeance, to allow them to remain viable as second line carriers operating Sea Hawks, Sea Venoms and Gannets (ASW variants) of the RNVR. Cutbacks (even before Sandystorm 57) meant that Warrior had lost her intended role before the refit was complete and her only RN service after that was as HQ ship for H-Bomb tests in the Pacific. Her return voyage was via Argentina and it would seem the Admiralty was already offering her to that country after paying off. The other ships refits were cancelled and they drifted into the reserve fleet from 1957 onwards, with Vengeance being sold to Brazil in 56 and Triumph being converted to a heavy repair ship. Venerable/Karel Doorman/25 de Mayo had the longest catapult of the entire class, installed by the Dutch between 55-58.

    The RAF lost out just as much as the RN did, in some ways even more so- who is it who now provides the nuclear deterrent?

    I think the Nuclear deterrent has proved to be a millstone for whichever service has to provide it; many writers have commented that the ’66 review was really down to the fact that the RN could have either Polaris or CVA-01, but not both. Whatever the truth, I would have been happy yo leave the deterrent role with the RAF if it meant we kept the carriers and the FAA intact.

    The cancellation of CVA-01 was followed by an offer from the US to sell us three Essex class carriers, at the time it was not stated which ones they would be and most assumed they would be three of the six most capable SCB-27C/125 conversions, but even these were not Phantom capable, primarily because they had wooden flightdecks. The modernised Essexs could operate the large A-3 Skywarrior because it was relatively slow and did not have afterburners. McDonnel Douglas had already offered a version of the F-4K Spey engined Phantom to the USN as the F-4L (ie a variant suitable for use from smaller decks than the Midways or supercarriers) for operation from the Essex class, but were turned down by the Navy for this reason. The three Essexs selected would actually have been drawn from the unmodernised hulls so they could provide a ‘blank slate’ for conversion to RN standards, and this would mean a ‘Victorious’ style stripping to the Hangar deck and starting again almost from scratch, producing ships with steel if not armoured flightdecks and probably deleting the portside lift in favour of a waist catapult/longer angled deck, with the second catapult forward. Admittedly this would be easier to do with an Essex than a British Fleet carrier but would still mean three to four year refits for each ship. The RN estimated that the completed ships would only have fifteen years hull life left to them after completion of their refits (due to the fact that they were built during the war and had used up between a third and a half of their planned hull lives; War-built ships tended not to be expected to last too long and it is to the credit of those involved in their design, construction, operation and maintenance that so many lasted as long as they did), so represented a poor return on the money. The government had already decided to end Naval Aviation in the RN and the rundown of the carrier force was announced later than the CVA-01 cancellation, hence the US offer. The Americans at first thought that the problem was about the design of CVA-01, not a fundamental shift away from carriers altogether.
