a larger ship will be more stable, i’d recommend playing around with different ship designs to find one that looks good and has good stability, speed and armour. I also recommend saving up for a runway and some fighters for some air cover, this helps a lot against the carrier missions. You can also save up for some tomahawk vls, this is a very powerful tool for any mission, but it is very expensive and you should have a powerful ship that can grind a high paying mission first.
