PA-75 French Carrier concept 1970's

For that price, fixed wing aircraft would have been a must.

Question, then: what kind (and how long) of catapult could have been fitted to this vessel ? 50 metres ? 75 metres ? :confused:

weren’t part of the idea of nuclear propulsion in PH75 was due that in the allready small size, eliminating the stores for fuel would have allowed much more effective use of the limited volume, like the mentioned use as replenishment ship for the other non-nuclear powered ships in the task force.

I like the desing very much, small as possible, but still nuclear;) Sofar this is the closest thing anyone has ever get to my most pervertic fantasy of nuclear powered minesweeper.
Someday (or nigth) when I cannot get sleep and have been drinking enough, I will come up with good reasons for building such…some day…

One of the main things I don’t understand about the concept is the nuclear propulsion. For ASW or convoy escort missions in the Mediterranean or North Atlantic it would have been completely unnecessary. For amphib operations, she would have most likely deployed with non-nuclear LPDs and other non-nuclear ships. Contrary to a CTOL carrier, high speed endurance was not needed for helicopter operations or deployment to crisis spots.

That “3rd French carrier” being Arromanches:

I disagree.

PH-75 was a planned replacement for the third French carrier, with perhaps a second unit taking over JdA’s wartime role as a helo carrier (probably unlikely).
CdG would have been built in the 90s anyway, as replacement for the “real” carriers; either that, or a similar system for the same purpose. Only then with some experience in nuclear propulsion on large-scale ships, likely preventing those certain problems occuring in that field with CdG, and perhaps opening the path to a second CdG. PH-75 would definitely have prevented the Mistral class though, which has pretty much the same delivery layout with somewhat less troops, and dock facilities instead.

Beautiful ship, but I’m glad she was never built.

The concept was very flawed: the equipment fit was very high end and therefore very expensive (C3, weapons, propulsion etc). Yet the added value she would have brought to the French fleet was very limited. Her missions were only ASW and helicopter assault, both of which could be done well enough by Jeanne D’Arc at a fraction of the cost (+ dedicated frigates & LPDs).

For that price, fixed wing aircraft would have been a must. She was also too small, so she wouldn’t have offered good value for money, given how cheap steel is. Finally, she looked a lot like a carrier, so if she’d been built she might have threatened funding for CdG.

Wow! Thank you everybody. I had been looking for infos about the PH75 for a long time.

Hey. It still looks cool, even when compared to current designs… 🙂

PA75 – PH 75 Carrier — Information

Dear Sirs

Please find Attached — A Document containing the Information which I have on the PA75 / PH75 Aircraft Carrier Concept of the 1970’s

Regards

Karakris

Did you get my message, Jazz?

PA 75 was renamed PH 75. Unsure if there were any major changes, although note the displacements are the same.

Thanks Peter G for the additional info, Terran suggested also that it may be PH-75 so I will search under that for a while Cheers JAZZ

PH 75

Cannot directly help but the concept before PA 75 was the PH 75, which is probably very similar.
PH is Porte-Helicopteres
PA or Porte-Aeronafs would have carried VTOL aircraft

PH 75 would have entered service in 1981.

18,400tonne full load (16400 standard), length 682ft (208m) beam 86ft (26.4m),
Nuclear reactor with 2 shafts (65000 shp). Range on emergency diesels would have been 3000 nm for 18 knots.
Armament: 2 Crotale SAM, 4 Model 1968 100mm
Radars: DRBV 26, DRBV 51, DRBC 32
Sonar: DUBA 25
890 crew plus 1000 troops (further 500 in some hanger space)
10-25 helicopters

Role was amphibious assault (Puma) with secondary ASW (Lynx, Super Frelon) . Hanger was 84 x 21 x 4.5 metres. Lifts were 15 t.

Carried 1000 m3 of aviation fuel and 1250 t FFO to refuel escorts.

sorry I ment aircraft carriers in the broader sense…I don’t fancy telling Jane’s to take all the helicopters out of ‘Janes All the Worlds Aircraft’.

PA-75 is designation under which it tends to be classified – by janes and in Roger Chesneau book ‘Aircraft Carriers of the World 1914 to the Present’ but its worth a try..thanks

I believe it is PH-75, not PA-75.

Mmm, perhaps that is because you are looking at aircraft carriers. The pictures however show a helicopter carrier, much along the lines of an improved Jeanne D’Arc training/helicopter cruiser.
