The Delta Flyer-type was a Starfleet shuttlecraft designed and built by the crew of USS Voyager during the vessel's stay in the Delta Quadrant, from which its name was derived. Two vessels of this type were constructed during Voyager's return to Earth from the Delta Quadrant.
Although Lieutenant Tom Paris had been petitioning his superiors on Voyager for some time to allow him to construct the first incarnation of the Delta Flyer, he had been overruled many times due to the vessel's lack of necessary resources to construct a new vessel from scratch. When the crew realized that class 2 shuttles were becoming inadequate in the increasingly hostile Delta Quadrant, it took the near-loss of a multispatial probe to finally convince Captain Kathryn Janeway and Commander Chakotay to construct the vessel, Tom already had a shuttlecraft design simulation ready.
The vessel blended Starfleet and Borg technologies, and was designed in collaboration between Tom Paris, Lieutenant B'Elanna Torres, Lieutenant Commander Tuvok, Ensign Harry Kim, and Seven of Nine. It featured an ultra-aerodynamic tetraburnium alloy hull, extendable warp nacelles, parametallic hull plating, unimatrix shielding, and a Borg-inspired weapon system, including photonic missiles, most of which were Paris' conceptions. For aesthetic reasons, Paris designed the flight controls to resemble those of 20th century aircraft. But to Paris' disappointment, the addition of dynametric tailfins was denied by Tuvok.

Both versions of the Delta Flyer featured retractable warp nacelles, but while the first version only featured a standard impulse drive, the second version employed retractable impulse thrusters that greatly increased the vessel's impulse speed when deployed. (VOY: "Extreme Risk", "Drive") Additionally, the Delta Flyer's propulsion systems and hull integrity allowed the vessel to operate under water. (VOY: "Thirty Days")
Both versions of the Delta Flyer featured phasers and photon torpedoes. Additionally, the first version was designed with a Borg-inspired weapons system created by Seven of Nine, which included photonic missiles. The second version of the vessel featured a pulse phased weapon system. Torpedo launchers were located both fore and aft, with the first version featuring two torpedo launchers on either side of the vessel facing forward, and the second vessel with a single launcher on the ventral surface.

In 2375, the Delta Flyer was designed to utilize immersive shielding and the unimatrix shield system designed by Lieutenant Commander Tuvok. Tetraburnium alloys were used in the vessels construction, in addition to parametallic hull plating. (VOY: "Extreme Risk") Multi-adaptive shielding was incorporated to the Delta Flyer later in the same year. (VOY: "Dark Frontier") The Delta Flyer II was upgraded to include pulse phased weapons and a duranium-enforced hull. (VOY: "Body and Soul")
Command and control systems
The cockpit of Delta Flyer-type vessels featured workstations for tactical, operations, and engineering personnel. The helm was located in the front of the cockpit. While the tactical, ops, and engineering stations featured a standard Federation LCARS interface, the helm combined this with physical buttons, knobs, and levers to give the pilot more control over the vessel. The second vessel expanded upon this concept by replacing the LCARS display on the helm with two manual steering columns. (VOY: "Extreme Risk", "Drive")
The Flyer's large size permitted comforts not standard to Federation shuttlecraft. The vessel featured a large aft compartment that featured a retractable biobed for medical situations. Despite this inclusion, the Delta Flyer's medical accommodations were limited and primarily intended to stabilize a patient until he or she could get back to Voyager for treatment.
Work stations were featured on either side of the bed and replicators were located at various points inside the craft. Delta Flyer-type vessels were capable of accommodating up to five people comfortably.

In the MMORPG Star Trek Online, Delta Flyer-type shuttles are known as the Delta-class.
The original Delta Flyer herself made a brief appearance in Star Trek: Voyager - Elite Force.
