A Starfleet class of the 2380s whose lead example on screen is the USS Voyager-A, Admiral Janeway's large exploration ship in the second season of Star Trek: Prodigy.
The Lamarr class is a big, long-range explorer that carries forward the swept look of the Intrepid class on a much greater scale. It has room for extensive laboratories, a cetacean operations section and a complement of cadets and warrant officers in training.
The USS Voyager-A, registry NCC-74656-A, is introduced in the second season of Star Trek: Prodigy in 2384. Admiral Kathryn Janeway takes it to the site of the wormhole left by the Protostar in the hope of finding Chakotay, with the Doctor aboard and Dal, Gwyn's friends and the other young Protostar crew serving as trainees.
