At least two wolfpacks will take down the Rocketeer easily, and most recommended strat to use.

Rocketeer
critical Threat
Heavy Armor
Description
A flying, heavily-armored rocket platform, armed with high-explosive rockets with a huge-range, causing area-of-denial coverage; slow movement is its only saving grace. As with all flying ARCs, its engines are its achilles heel, but good luck landing shots on them as your vicinity is exploding around you.

Possible Drops
As ARCs take damage or are destroyed their parts break off, which depending on their size yield different types of loot; the table below shows cumulative loot.

Looking on my game summary, seems like Rocketeer has 1050 HP and one Wolfpack can deal ~1000 damage (if it hits perfectly). Also got 2 Drivers, looks like they always drop in main hull and have a chance to drop in thrusters.
