ID me an aircraft please!

Saw these at Carcassonne airport. Whilst we were on holiday they were flying every day, in formation, often at relatively low level. No idea what they are or what they were doing but presume something to do with French fire service?

Sorry for the image quality - taken on a phone from the window of a taxying 737.

Wow, v quick, thanks. Should have seen it was a Grumman, given the nose and cockpit look.
