Nuclear Helicopter Carrier

Nuclear Helicopter Carrier

A Nuclear Powered Helicopter Carrier ship

You heard that right yeah I…uh…I…ugh what were the French thinking!!!

The Nuclear powered Helicopter Carrier PH-75 was designed in 1970 with 1 ship proposed as she was to displace 16,400 tonnes at her standard with her full load of 18,400 tonnes.

Her powerplant was to be a nuclear reactor probably the Aerva CAS-230 driving two shafts generating 65,000 horsepower and a speed of 28 knots.

She had a crew of 890 and a troop capacity of 1000 and 500 more could be on the hangar deck.

While the ship had no armour, she did have two 8-cell R440 Cells for 16 Crotale Surface to Air Missile Systems with two 100mm/55 Modele 1968 Dual Purpose Anti-Air Guns.

She was to have 25 Helicopters presumably Sud-Aviation SA321G Super Frelon or Westland WG-13 Lynx HAS.2/4 Anti-Submarine Warfare Helicopters or a mix of SA321GA Super Frelon of the French Navy or French Air Force SA330B Puma for Amphibious Assault.

Thankfully the French cancelled this ship in favour of the conventionally powered Mistral Class Helicopter Carriers

Although had the Nuclear Powered Helicopter Carrier or presumably the Bretagne Class Helicopter Carrier went into service it would have been replaced by Mistral Class anyway.

Here’s a picture of the PH75 Nuclear Helicopter Carrier:

PA76 Light Aircraft Carrier

The PA76 Light Aircraft Carrier or as I call it the Voltiere class Light Aircraft Carrier was a proposal derived from the cancelled nuclear PH-75 Helicopter carrier

The PA76 had a standard displacement of 16,400 tonnes and a full displacement of 19,400 tonnes, she was 630 w.l in length and 87 w.l in width.

Instead of the Aerva CAS-230 Nuclear Reactor, She was to be powered by two Rolls-Royce Marine Olympus TM3 Gas turbines and two AGO Diesels with two shafts generating 65,000 horsepower for a speed of 28 knots.

Her Radar systems were probably to be very impressive as its air defence radar consisted of a DRBV-26 Jupiter Air-Search Radar and DBRV-51 Air-Search Radar, its missiles would be guided by a DRBC-32 Fire-Direction Radar and its Anti-Submarine Sonar is the DUBA-25 Tarpon Anti-Submarine Sonar.

The Ship’s Armament was to be two 8-cell Crotale SAM for sixteen cells and two 120mm guns of an unknown type.

The PA-76 was to have two catapults with a capacity of 25-30 aircraft and helicopters presumably the Dassault Super Etendard strike aircraft with Breguet Alize carrier based Anti-Submarine Warfare planes and Sud-Aviation SA321G Super Frelon carrier based Anti-Submarine Warfare Helicopter

Why wasn’t it built well as Reddit User Keyan_F explains

The answer should be obvious tbh: in 1976-77, most of the Western world, including France, is reeling from the aftershocks of the 1973 Oil crisis (and a second shock will come soon), defence budgets worldwide are heavily curtailed and it’s clearly not the time to build a big nuclear warship. During the same period, Presidents Ford, then Carter refuses to approve funding to build more Nimitzes, and even Zumwalt’s CVV has trouble gaining traction.

Also, even if France had the funding to build such a ship, they very probably would have found out that building either an updated but still conventional powered Clemenceau or a full sized nuclear powered carrier (the Richelieu project) would give a better bang per buck, an issue that scuppered the aforementioned CVV.

Personal Opinion

This should have been built as it would have given the French more ships and allowed the Clemenceau class ships for power projection duties but why didn’t they built this and what might the ramifications have been had the PA76 gone into use? and what might the French have named her?

Proposed Soviet Carriers

So first things first, yeah I know I’ve not posted since July last year but I’ve had a lot going on but I’ll try to make more posts but I can’t promise anything

So I was looking around the secret projects forum and weapons and warfare and found some proposed soviet aircraft carriers

Project Kostromitinova

1st is Project Kostromitinova carrier which was to have 66 fighter aircraft and 40 Bombers/Torpedo Bombers with two catapults.

Her gun armament was to be sixteen 152mm guns with twenty-four 100mm FlaK guns, twenty-four 37mm guns and forty-four 23mm guns.

Her armour on the deck was to be 180mm thick, Her side armour was to be 100mm thick and the hangar had 40mm of armour with her top speed 32 knots with a range of 8000 miles when travelling at 18 knots.

Our 2nd ship is the Project 71 Carrier

Project 71

Project 71 had a speed of 34-35 knots and had an armament for eight 100mm Anti-Air Guns, sixteen 37mm Anti-Air Guns and twenty 12.7mm Anti-Air Heavy Machine Guns.

The armour belt was presumed to 100mm thick armour on the outer hull and 75mm thick armour on the inner hull while the flight deck had 90mm thick armour while the bridge had 50mm thick armour.

Her Air Wing was intended to have twenty fighter aircraft and ten reconnaissance-bomber aircraft.

Our 3rd proposed Soviet carrier is the Project 72 Carrier

Project 72

The Project 72 Carrier’s gun armament was suppose to be twelve or sixteen 130mm Anti-Air Guns, sixteen 85mm Anti-Air Guns with twenty-four 37mm Anti-Air Guns and forty-eight 23mm Anti-Air Guns.

The armour belt was to have 90mm of armour and the flight was to have I think 60mm of deck armour

Side Note: the Deck armour was this 30mm+(50-80)mm.

Her air wing was to be 62 aircraft.

Our final carrier is the Project 85 Light Aircraft Carrier

Project 85 Light Aircraft Carrier

Project 85 Light Aircraft Carrier was a proposed Soviet Light Aircraft Carrier had a propulsion system consisting of steam turbines that produced 144,000 horsepower giving a top speed of 31.4 knots and cruising at 18 knots gave a range of 5000 nautical miles or 5753 miles.

Her Crew was to be 1850

Her armament was to intended to be, sixteen 100mm Anti-Air Guns, twenty-four 57mm Anti-Air Guns and thirty-two 25mm Anti-Air Guns.

Her aircraft was planned to be forty navalised MiG-19 Farmer variant known as Tigr and two Mil Mi-1 Hare helicopters.

What do you think of these proposed soviet carriers and what could they have been called had they gone into service and would they have been replaced by the Kiev and Admiral Kuznetzov class Aircraft Carriers

BASC-220 – Spain’s CATOBAR Carrier

The BASC-220 or Spain’s CATOBAR Carrier

What the Ship might have looked like had the Argentines used it

Yes this is a real unbuilt design by Spain in the 1990s who tried to sell it to China who at the time never bought it probably cause they couldn’t afford it or didn’t need it while Brazil could’ve bought it but didn’t probably as they were going to get the Clemenceau-class aircraft carrier from France in 2000 while Argentina was financially broke and hadn’t recovered after their disastrous defeat in the Falklands War against the UK.

The BASC-220’s total length was 241.8 metres with a beam of 29.5 meters, a depth to flight deck of 22.5 metres and had a displacement at full load was 27,000 tonnes.

The propulsion was apparently a Combined Diesel and Gas / Combined Gas And Gas system which gave 76,440/88,500 Horsepower for a max speed of 25.5 / 26.5 knots whose range at 15 knots was 7500 miles.

Her Anti-Air Defensive armament is unknown but she was capable of 24 aircraft probably helicopters too as it was designed for up to 20 F-18-like aircraft and 4 Anti-Submarine Warfare Helicopters.

Sadly Spain’s carrier export ambitions never really took off but what do we they’d have called this although my info is probably not the best as information about this ship is very hard to find.

I know you’re getting tired of the frequency of these posts and I’ll try to cut back on the number but when I find an unbuilt ship that never made it, I feel I have should share this with you lot.

Implications of the CVA-01 had she been built

Link to CVA-01 Post: https://diamondsofthenight.home.blog/2020/10/10/cva-01-aircraft-carrier-2/

In a post I made I talked about the CVA-01 compared to the Kitty-Hawk but it was a mess but thanks to some feedback and suggestion gave this post so let’s begin

The CVA-01’s air wing was suppose to be up to 50 aircraft but apparently might have had room for 68.

It was suppose to have eighteen F-4K Phantom two but was apparently able to carry eighteen more and had eighteen Blackburn Buccaneer S.2C or S.2D Strike aircraft with two or four Blackburn Buccaneer S.2 coverted tankers with four Fairey Gannet AEW Mk.3 for Airborne Early Warning and single Gannet COD.4 with five Westland WS-61 Sea King HAS.1 for Anti-Submarine Warfare and two Westland WS-58 Wessex HAS.1 Anti-Submarine Warfare converted to Search and Rescue

So the CVA-01’s being built has implications are more interesting as it raises questions

1. Does the Royal Navy drop funding of Harrier in favour of fixed-wing naval aviation?

A. Somehow I don’t think so as there was a need for the Harrier so yeah the Sea Harrier would probably get built to give close air support to the Royal Marines and as the Invincible Class were originally suppose to be Anti-Submarine Warfare carriers so in the end no they probably they’d keep funding the Sea Harrier

2. To build its airwing, does the Royal Navy continue to procure U.S. naval aircraft or does it instead focus on domestic production, or even a partnership with France?

A. Possibly they could’ve bought the F-14s as the RAF did consider it although rejected it although maybe later when they needed to modernise the carrier air wing they could’ve bought Rafale Ms although maybe the Eurofighter Typhoon’s navalised proposal probably would replaced the F4 & Buccaneer

3. How does CVA-1 perform in the Falklands campaign and how does it influence it? Follow-up, does the Falklands War even happen. Argentina’s entire military case for their invasion was a perceived inability of the Royal Navy to project force in the South Atlantic. Does CVA-1, with a far more robust and longer range airwing, change their calculation? I’d argue it does

A. The CVA-01s likely would’ve been the flagships of the taskforce along with the Invincible and Centaur class light aircraft carrier making up the carrier force, the destroyer force would be the Bristol class, Sheffield class and County class Destroyers, the frigate force would’ve been made of the Broadsword class, Amazon class, Leander class and Rotesay class frigates.

The Landing ship force would’ve been the Fearless class and Round-table class landing ships with castle class offshore patrol ship and a large fleet of supply ships which would have been Fort Roselie class, Tide class, Oi-class, Leaf class and Rover class supply ship

Musn’t forget the Submarine force that would’ve been the Valiant class, Churchill class and Swiftsure class SSNs and Oberon class attack submarines.

Odds are had the British had the CVA-01s in the Falkland task force they had then the war would’ve been easier as the F-4Ks could do combat air patrol over the fleet and would have given the British complete air supremacy as they’d have been facing the Argentine Air Force French Dassault Mirage 3E & Israeli-made IAI Dagger A fighters and US-made Douglas A-4B & A-4C Skyhawk and Argentina’s own IA-58A Pucara ground-attack turboprops and British-made English-Electric Canberra B.62 jet bombers as the Mirage 3s were packing two 30mm Defa 552 Revolver Cannons with 250 rounds and two R.550 Magic and one R.530 missiles while the Daggers had the 30mm cannon and R.550 Magic 1s

When compared the British Phantoms which likely would’ve had the four AIM-9L Sidewinders and up to six AIM-7D Sparrows which would have probably meant the F-4s could get more shots on target.

Once the Argentine Air Force was crushed as the Buccaneers would have probably gutted the Argentine Navy probably sinking their both their carrier group which were made of a lone colossus-class light aircraft carrier and their southern strike group of a Brookyln Class Light Cruiser and Allen.M.Summer Class Destroyers and the fleet tankers assigned to their respective task force fleets leaving their Navy severely crippled.

Although its more likely the Argentines wouldn’t have bothered to invade to begin with…..

However it should be kept in mind that the Argentine military junta were deeply unpopular at the time so odds they probably would tried anyway but then how much worse would the Argentine military be today I wonder?

4. How does the construction of CVA-1 influence Royal Navy shipbuilding for the second half of the 20th Century and beyond?

A. Most likely the Royal Navy would’ve continued with CATOBAR carrier in the Queen Elizabeth Class or an improved carrier based on the CVA-01 with a newer powerplant similar but an enlarged version of an Integrated Electric Propulsion type system like the one used on the Queen Elizabeth Class Carriers with F-35Bs replacing the Harriers and F-35Cs replacing whatever the CVA-01 used in place of the F-4s and Buccaneers.

The most probable replacement for the F-4K Phantom 2 and Buccaneer S.2 would be the Navalised version of Hawker-Siddeley HS.1207 or as i dub her the Wasp in the fighter role and Hawker-Siddeley HS.1197 Buccaneer S.3 strike aircraft.

Sadly the CVA-01 was cancelled shame really as she would’ve been a good asset to the Royal Navy and presumably NATO as well.

Germany’s carrier conversion fleet

So I’ve already talked about the Graf Zeppelin Class Aircraft Carrier but the Nazis had several Converted Carrier ideas that were planned but never finished and here they are

Our 1st other German carrier is the I-class which was a conversion of German-Passenger Ship, the SS Europa of the Nordduetscher Lloyd passenger ship line and she was to have Twenty-Four BF-109T-1 and Eighteen Ju-87C Stuka aircraft and her guns were to Twelve 4.1-inch SK C/33, Twenty 1.5-inch SK c/30 Anti-Air Guns and Twenty-Eight to Thirty-Six 0.79-inch SK C/30 Anti-Air Guns.

Our 2nd other German carrier is the II-class which was the incomplete French Navy cruiser the F.N.S De Grasse which was suppose to have eleven BF-109T-1 and twelve Ju-87C Stuka aircraft while her guns consisted of Twelve 4.1-inch SK C/33 and 1.5-inch SK C/30 Anti-Air Guns and Twenty-Four 0.79-inch SK C/30 Anti-Air Guns.

The 3rd of the German’s other carriers is Jade class aircraft carriers which were conversions of German passenger-liners, the SS Gneisenau and SS Potsdam of the Nordduetscher Lloyd passenger ship line were intended to carry twelve BF109T-1 fighters and Ju-87C Stuka bombers, these carriers were to have ten 4.1-inch SK C/33 and 1.5-inch SK c/30 Anti-Air Guns and Twenty-Four-Thirty-Two 0.79-inch SK C/30 Anti-Air Guns.

And finally this the Weser class whiich was a converted Admiral Hipper Class Heavy Cruiser, the K.M.S Seydlitz and were to be armed with ten BF109T-1 fighters and ten Ju-87C Stuka bombers.

Her defensive armament was ten 4.1-inch SK C/33 and 1.5-inch SK c/30 Anti-Air Guns and twenty-four 0.79-inch SK C/30 Anti-Air Guns.

Would these converted carriers have made any difference to the war if they were finished and what would the implications be if any or all of them been completed?

Frankly not really as they’d all likely be hunted down and sunk by the UK’s Royal Air Force and Royal Navy

French Post-WW2 proposed carrier designs

So after WW2 The French seem to catch up in carriers

First is the PA16A/PA16B which had a displacement of 20.000 tons which had a speed of 30 knots and an air wing capacity of 40 aircraft and the PA-16/PA-16B was based on the cancelled Joffre design.

The 2nd post-WW2 Carrier was the PA19 carrier that was 260 metres long and had a displacement of 30,000 tonnes with a speed of 30 knots and was armed with twelve 155mm guns in four triple-turrets.

She ultimately had a single hangar with two lifts with a capacity of 50 aircraft.

The PA19 was the French trying to redesign the Joffre Class Aircraft Carrier with the lessons of World War 2 but it didn’t work out.

Now we come to the PA25 aircraft carrier which was the first clean-sheet design that had a displacement of 25,000 tonnes and a speed of 30 knots.

Her Gun Armament was eight 114mm Guns, sixteen 37mm and forty 20mm Guns.

She had a single hangar with two lifts with an unknown number of aircraft.

There was a carrier design based on the helicopter carrier I talked about, but I’m gonna do a separate post at some point.
