Today it’s the Kelvin and the Franklin.
First the Kelvin. It’s roughly Miranda class equivalent (to go with the constitution refit alternate timeline Enterprise). It’s ability boosts its defence to keep it alive a little longer. Captain Robau, as a blue shirt, has a science/scan related ability…and George Kirk has a modified dominion suicide run ability. This one works better the less evasive the target ship is.
The Franklin is even smaller, with only 1 attack dice. It can, however, make additional attacks should it hit…almost seems like that would be handy against…I dunno…fighter squads maybe?
Former MACO Captain Edison gets a free shot with a MACO squad, allowing you to use the Franklin as an agile little troop transport, with the remaining crew helping to keep the ship alive while it weaves through enemy lines.
