After the Dominion war Starfleet felt the need for ships that are substantially larger than the Peregrine class fighters, but still smaller than full size starships. The Defiant was famously effective but even that was too big to effectively engage the Jem’Hadar attack fighters.
The Orca was conceived as an intermediate spacecraft that ewould be cheap to build and deploy in numbers, but still durable and deadly enough to make an impact. The design team also decided to use the Orca as a proof of concept that the Multi-Vector paradigm scales down to smaller ships.
This makes the Orca a small and deadly ship that can occasionally be two small and deadly ships.
