Via War is Boring, a French Ministry of Defence official has indicated that France has agreed to sell a Mistral class amphibious warship to Russia. The article gave no indication about the rest of the deal (such as the licensing of the construction of additional Mistrals in Russia), but it did note that France's NATO ally Lithuania had expressed concern about the deal. The contract for the 21000 ton warship, however, appears to have been too tasty an offer to turn down.
...This article indicates that France will sell four Mistrals to Russia. The implication seems to be that all of the ships will be built in France, although it's a touch unclear what this means:
France has agreed to sell Russia a Mistral-class amphibious assault ship and received an order to build another three, Radio France Internationale reported Monday.
I don't imagine that this can mean selling one existing ship, then building three others; perhaps it means that one sale is final, and three are still in discussion?
