The Arazu also has a 40m3 drone bay and a bonus to hybrids to allow it to do some damage, but this is almost an afterthought.
For fleet ops, the Arazu's job is to keep distant enemies pointed, either until tacklers arrive or after tacklers have been shot down. Here, stealth is still key if you're following the bait ship. Just don't uncloak too soon or you'll alert your prey to the trap. If you're with the main fleet, keeping your stealth cloak up can still keep enemy scouts from getting an accurate number of your forces.
For covert fleets, your role is initial point on a single target. Getting into point range shouldn't be a problem. However, unlike stealth bombers, force recons don't have a reduction to unstealth lock penalties. This means you're sitting there waiting to start locking for at least 5 seconds. This makes communication with the rest of the fleet absolutely vital if you don't want to 1) have everyone else uncloak before you have a point and damp up, thus losing either your prey or your fleetmates' ships, or 2) not have your fleetmates come in on time and losing your prey and your ship.
