Unlock the 4th fleet like Wingtipswaltz  said, you need every resource you can get from expedition. And NO, extra drumcanisters don't give you extra resources unless you have the daihatsu landing craft equipped. However, they increase the chance of huge success from expedition ONLY for expedition that needs drumcanisters such as exp 21, 37, 38, etc.
