    IIRC the CDeG was using props from the Foch for a while. Was this ever corrected and the correct props installed or is she still using the older ones?

    They were removed from Clemenceau, not Foch. She is still using hers. CdG has some new props now. If they still don’t work, they could always buy Invincible’s, last seen sitting on her flight deck in Pompey…

    In peacetime trials take years, in wartime they take days. Just shows how much unecessary beaueacracy is involved. I recall during the Falklands war RAF Harrier GR3s were modified and cleared to fire sidewinders in a couple of weeks. Imagine how long it would have taken in peacetime (answer: it wouldn’t have happened at all). Prior to the war the Sea King AEW was rejected as unecessary and too expensive for such a short production run (10+ aircraft), and would take years to produce. In reality it took eleven weeks. I have no doubt should HMS Daring’s services be required in combat tomorrow her Sea Vipers will be ready. Can’t beat combat trials for realism!

    Did Minas Geras get 25 de Mayo”s steam cat in the mid 90s?

    Not the whole cat, just some parts from it. 25 de Mayo’s cat was much longer than Minas Gerais cat for a start, and from a different manufacturer, so some of the parts may not have even been compatible. 25 de Mayo’s cat extended back behind the forward lift and was the longest stroke cat ever fitted to a Colossus class carrier, whilts Minas Gerais cat only extended back to the forward end of the lift. During the 90s the Brazillian Air Force’s Trackers were withdrawn from service and for several years Minas Gerais operated solely as a Hleicopter carrier, though the Argentine Navy did use her for Carrier landing practice for their Turbo Trackers and Super Etendards (touch and gos only). One Super Etendard did accidentally ‘hook’ a wire with it’s hook in the up position, due to an excessive nose high atitude, and the aircraft had to remain aboard until the ship returned to port as the cat was non operational at the time (with no fixed wing aircraft normally embarked, this was understandable). Around 1998 some key parts were sourced from Argentina to make Minas Gerais cat serviceable again, but this was by no means the whole cat, which went with 25 de Mayo to the breakers in 1999. 25 de Mayo had a Mitchell Brown BS4 long stroke catapult and Minas Gerais had a McTaggart Scott C1 catapult if memory serves. Below are a few photos that should illustrate the difference between the two ships cats.

    Well, I would have to do a little research. Yet, I would be surprised if the AIM-9G was nearly as good as a AIM-9L. Even from the rear aspect…….:confused:

    The only real difference between the 9 Golf and the 9 Lima was the engagement envelope, the Golf being primarily a rear aspect missile and the Lima being an ‘all aspect’ missile. With the Lima the RN’s pilots had the option of engaging head on or from the side, but this was never required in combat. As all the air to air training prewar had been with 9 Golfs then it is understandable that the pilots would normally engage in a stern chase (successfully).

    Both carriers were due refits?I know Hermes was due, but Invincible aswell?Wasnt she only a few years old??Imagine how different it could have been had the SuE got through and got 1 or 2 lucky hits with exocets on either of the carriers.It could have been game over.

    ‘Refits’ is a term that covers smaller maintenance periods too. Most warships undergo a short refit of a matter of weeks every year between major overhauls. Invincible was new, but still had teething problems (notably vibration from her propellers, then the biggest in the Navy) and also had to carry out an engine change underway to the Falklands, a job which had been expected to be carried out alongside at Portsmouth. She had already seen two years service and was due for some modifications. Both carriers had just completed excercises and were due a period of maintenance. If a carrier had been disabled in the Falklands war then the only realistic hope would be relief by Illustrious which was being rushed to completion, though she wouldn’t have arrived earlier than July anyway.

    Well, the availability of the Sidewinder (AIM-9L) Equipped Sea Harriers plus the SSN’s. Made the Victory Possible…………..Sorry, I think it was much closer than you think. As the loss of the HMS Hermes or Invincible could have changed the outcome.

    Just my opinion…….:cool:

    The AIM-9L effect on the outcome is somewhat exaggerated, as all SHAR air to air engagements in the Falklands were bfrom astern. If they had been armed with the more usual AIM-9Gs the outcome would probably have been the same. The ‘-9Ls just gave the Fleet Air Arm more options that in practice were not needed. The SSNs did effectively neutralise the Argentine Navy after the Belgrano was sunk, with reportedly only three boats deployed. Many of the ships in the Task Force (including both carriers) were overdue for refit before they sailed. Indeed Hermes had started her refit shortly before the invasion and embarked her air group in Portsmouth dockyard with her island covered in scaffolding.

    Shades of the 1970 ‘SAM Kotlin’ incident when a Soviet destroyer tried to run across the bows of HMS Ark Royal at night whilst she was launching aircraft. It sounds like an act of crass stupidity to put a warship into dangerous proximity with another ship if the reports are correct. Not the mark of a professional and competent world class Navy.

    As far as I’m aware steam turbines are nosier than both gas turbines and diesel engines. Diesel subs are far quieter than nuclear subs the only reason why nuclear power is used in submarines is it is the only power source that can be used for very long underwater patrols.

    The reason Diesel subs are quieter than Nuke boats is because when submerged they DON’T use their diesel engines! They run on batteries unless in a low risk area when the diesels can be used to charge the batteries, preferably on the surface but also when submerged if a ‘snort’ mast is used. Nuclear reactors have a lot of soundproofing as well as their radiation shielding and a great deal of attention is paid to silencing just about everything on a sub. Silence is truly golden.

    Update I popped into Wh Smith on my way home from work today and there was a stack of March editions in stock. I’ll get one on the weekend, but it is of the 1950s Ark not 1970s. Maybe April will feature Ark later in her career?

    We can but hope. My copy of the February issue just said part two in March.

    With her arrester gear installed she could probably operate the Mig29k STOBAR but it would be a BIG JOB!

    Did UK gov remove her arrester gear engines when she went Harrier Carrier or are they going rusty below deck?

    Hermes conversion to a Commando Carrier between 1971 and 1973 involved the removal of her catapults and arrestor gear (including all below decks equipment), and cost abour £25million. Additionally a small chunk of her angled deck was cut away in order to fit the davits for her LCVPs, and the sponson for her projector sights went too. The island was extended aft to accomodate satellite communications gear. After conversion her bows sat a foot higher in the water than her stern, so the loss of her cats at least did make a noticeable difference to her. Many of her internal compartments were re organised to provide accomodation for up to 900 Marines and their gear. In 1977 she was refitted as an ASW carrier, the chief difference being a type 184 sonar installed in her hull. Her Commando facilities were unaffected.

    In 1980-81 she was again refitted, this time gaining a 12 degree ski jump at the bow, though contrary to popular belief her deck was not reinforced to operate Sea Harriers, as it was already built to take the kinetic energy of a Sea Vixen or Buccaneer hitting the deck at 130knots. A Sea Harrier weighs half what either of those two do and it arrives on deck with a vertical speed of about five to ten knots. Nor is the exhaust from a Harrier hot enough to require a special coating on the deck, as the wooden decked Spanish carrier Dedalo proved.

    Why no “Sea Grippen”?

    Same reasons as SeaPhoon, plus it would be further down the list becasue it doesn’t have the virtue of being built by a potential user nation. No British jobs in Sea Gripen, at least some british jobs in SeaPhoon, as well as in JSF.

    Well hermes used to have cats and traps anyway, so it must be a simple job to ‘plug and play’!:D;):eek::diablo:

    IF (note that is a BIG if) the RN get its big carriers….and by some miracle of common sense got to cats and arrestor gear, woulf the RN purchase a few T-45s?

    For training purposes possibly, though I think it more likley we would sign a contract with the US to put our pilots through their training program rather than duplicate their capabilities. The Americans used to train enough aircrew for 15 flat tops, now it’s only 11. Add the needs of two British carrier air groups and there would still be some slack in the system. Provided we paid the cost of training our crews over there I don’t think there would be a problem. The RN already operates some Hawks, so adding another sqns worth might not be a great hurdle. If we do go down the CTOL path for CVF, the the T-45 is the logical choice, however we end up using it.

    India originally wanted Vikramaditya to bridge the percieved gap between Viraat leaving service IAC1 becoming fully operational, then helping to make up numbers towards the eventual stated goal of three carriers. The first goal has already fallen by the wayside as she won’t be ready much before the IAC, so to bridge the gap Viraat is having her service extended yet again. Now Vikramaditya’s only purpose is to make up numbers until the other IACs are built. If Russia keeps her, then India’s options are limited as regards increasing the number of flight decks available to the fleet. They could Buy/lease Invincible, and she could take over from Viraat for the next ten years or so giving the IAC/Mig29/Tejas program time to become fully operational, with Invincible taking on Viraat’s existing air group in the meantime.

    Well, I was thinking exactly the same thing! As the Vikramaditya combined with the Kuznetsov would give Russia a two Carrier Fleet tomarrow! This would like you said take the pressure off. Giving Russia time to build a fleet to compete with China, India, UK, etc. etc.

    As for the Su-33’s and/or Mig-29K’s. She could buy the latter as its already in production and wouldn’t need a large number. Further, she could keep both types if she wished…………..(i.e. with a small upgrade for the Su-33’s)

    Something is up…………..Yet, even if Russia truely wants the Ex-Gorshkov back? Is it really worth destroying there relationship with India to get it???:eek::confused::eek::confused:

    It’s possible the Russians might offer a compensation package, say a couple of DDGs or some Frigates. If this is their straegy it could be negotiations are already going on behind the scenes, which as we all know, do tend to drag on somewhat when the Indian Government is involved. They modelled their beaureaucracy on ours, so Normal speed is glacial. I’d imagine they’d want to separate the Carrier deal from the Mig 29 deal so they could continue with the latter. I think the two were bound up together originally (Buy the planes, we’ll throw in the carrier but you pay for the refit), so unpicking that contract could prove awkward.
