A task group for Star Trek's five-year mission

What ships should a Star Trek five-year mission include?

Clarke prefers two large explorers, four to six smaller ships, and two freighters, operating separately within supporting distance. Others question the size and composition of the group.

Clarke proposes at least one large warship, several smaller ships, and a pair of freighters for a five-year mission. His preferred group is two large explorers and four to six smaller vessels, illustrated by two Galaxies and six Intrepids. The ships would work over a wider area while remaining able to concentrate or reinforce one another. Some smaller ships would escort the freighters at the center of the operating area. A reply objects that this is effectively a battle fleet and questions whether Intrepids are the appropriate smaller ships. Clarke prioritizes sustained mutual support and the firepower needed to withdraw from a serious threat.
