Let's be clear on this:
the ship needed protection from the pirates.
Two pirate assault boats approached the Nivose "at great speed," Capt. Christophe Prazuck said, but a French helicopter intervened before the attackers had time to fire at the French navy ship.
The helicopter fired warning shots, he said.
The pirates, who had a mother ship as well as the two assault boats, are being held for questioning on the Nivose, Prazuck said. The vessels were carrying AK-47 rifles and rocket-propelled grenades, but the pirates did not fire, he said.
I am absolutely certain that the big pointy thing on the foredeck is cheaper than a helicopter flight.
