| style="text-align:left"| This is a staple expedition to gain buckets. It takes a short time and has a 50% chance to return a bucket. It also provides the most ammo per hour of any expedition. You should run 4DE in order to save costs.

| style="text-align:left"| This is another early expedition that is good for buckets. It has the same 50% chance to return a bucket like Exp2 but it doesn't give much in the way of other resources. Although 1CL2DD is a valid fleet, 1DD3DE has lower costs.

| style="text-align:left"| This expedition requires great success in order to return a bucket but it has an innate great success chance that scales with flagship level. If you do not have a girl that is at least level 128+ to be flagship, you will need to sparkle the fleet to get the most out of this expedition. It also does not provide much in the way of other resources like Exp4.
| style="text-align:left;" | Another expedition that requires great success to return a bucket. Like ExpA2, it has an innate great success chance but this scales off both flagship level and total fleet ASW. The flagship level is also steep at 128+ for a decent great success chance but the ASW requirement helps reduce the need to sparkle the fleet if you do not have a high enough leveled girl to be flagship. This expedition also provides a noticeable amount of fuel.
