To whom understand french.

The proof that there is something strange.
The same source report 2 differents price for the Horizon:

Here is 2.7 bilions € for 2 Horizons:
En définitive, le coût des deux frégates françaises, les Forbin et Chevalier Paul, atteint 1.9 milliard d’euros, auquel il faut ajouter le coût du système d’armes. La Marine nationale estimant le budget total à 2.7 milliards d’euros, le prix de ce dernier serait donc d’environ 800 millions d’euros

Here is 1.6 bilion €. There’s written 800 milion € at unit:

La commande de la troisième Horizon était d’ailleurs prévue dans la loi de programmation 2003-2008. Le coût très élevé de ces navires (800 millions d’euros pièce) est la raison principale de cet abandon.

Tmor, could u help us to translate from french to english?
Thanks.

Ultimately, the cost of the two French frigates, Forbin and Chevalier Paul, reached 1.9 billion d’ euros, for which it is necessary to add the cost of the weapon system(s). National marine estimating the total budget at 2.7 billion euros, the price of this last would be thus approximately 800 million; euros

2 ships at 1.9 billion > 950 million apiece plus the cost of weaponry.
cost of weaponry: 800 million for 2 ships.
total per ship: 1.35 million

The ordering of the third Horizon was d’ elsewhere envisaged in the law of programming 2003-2008. The very high cost of these ships (800 d’ million; euros part) is the primary reason of this abandonment

this would be in line with the 950 million excl weapons (when you build more units, the price per unit comes down e.g. because development costs can bespread out over more units).

You also need to factor in whether or not the amount is monetary units of a particular year (compare ‘constant dollar’): to get the same value as 1 dollar in year X, one might have to spend 1,1 dollar om year Y=X+1). Your first article is from 2007 and your second from 2005 > some effects of e.g. inflation?
