The French Breguet Atlantique are excellent MPA aircraft, made especially for submarine hunting. In fact they have been, for long, the only dedicated airfram built and designed from scratch for that purpose.
They have been constantly updated, can launch Exocet missiles, and all the antisubmarine stuff. To search for smugglers or rescue people out in the blue, they are anyway a little bit overpriced - that's why a significant number of Falcon 50 (and some Falcon 20) have been acquired and tailored for the job (appropriate radar, drop hatch, extra windows, even small pods to launch rockets...) So France has three types of MPA aircraft....
and the French navy is always available to help our so-good friends from over the Channel (same for aircraft-carriers ...) unless there is better to do in Africa or the Middle-East, where those aircraft are also used over the desert. So if they are too busy guys, sorry - try to find those subs off Scotland using combat divers, or charter Monarch or easyjet with sets of googles in the cockpit...
