Verdun French Aircraft Carrier (images)

[BROF]

Regarding BS.5 (From the section on Clemenceau and Foch (p.219))
- Built by Brown Bros.
- Can launch a 20-tonne aircraft at 90 kn with 2.8 g acceleration
- Interval between launch: 35 s (theoretical), 45 s (practical)
- The remainder are information about the installation itself such as the cylinders counts and connection + location of things such steam accumulator + blast deflector + bridle catchers

Nothing on the BS.4 unfortunately (I didn't seem to see it mentioned at all)


There were? Hmm... I didn't seemed to see it mention at all in book. Could you point me to a source?

SHD 2ème RM, Brest...

Typical government thing...
Guess I should write it up as a topic, the issue is all over the place now. Just not sure where, naval projects? Alternate history?

From Jean Moulin's book page 174 :
The two steam catapults are British BS 5 type catapults built by Brown Brothers. A slight confusion arose regarding the catapult type on the two aircraft carriers. Originally, the British used the term BS 4 interchangeably for both the "cantilever track" catapult (with a carriage running on rails attached to the pit covers) and the "centre rail track" catapult (with a carriage sliding in a central track rail attached to the pit).
On April 7, 1961, the Admiralty decided to differentiate between the two types of catapults, retaining the designation BS 4 for the former and adopting BS 5 for the latter. To avoid any confusion, French Navy aligned itself with the British, and the catapults of the Clemenceau and Foch became BS 5 simply by applying a note.
Ultimately, Brown Bros never built any 75m catapults...

I was pleasantly surprised to see on a model-making website that "my" Verdun PA-58, designed in 2015 (see #105 above), had been built using a modified Clemenceau model, which shows the project's stage of development with 8 x 100mm guns and two Masurca double launchers. The aircraft are SEPECAT Jaguar M, Vought F-8E (FN), GAMD Mirage IV M, and Breguet Alizé, giving a good idea of the very ambitious nature of the projec t!
