The Warden's Redemption is a VTOL dropship built by Captain Shack in early August of 2077 on the recently named planet Bob. The group noted noted its striking similarity to the Pelican dropship known from the Halo franchise.
Originally built to have more storage capability and more seats than before, it is considered to be a significant improvement over the previous Shack crafts. This one is a Vertical Take Off and Landing (VTOL) craft, and uses multiple thin thrusters to keep itself off the ground. It has a total mass of 129 978 kg and 2 fully closed cockpits.
The Pelican Warden had the major safety feature of having all thrusters away from the passengers and also an enclosed cabin for the passenger. Later retrofits would provide an escape hatch on top of the craft in the event the rear door were ever disabled or blocked. The belly of the ship also houses an area that an R-5 recon drone can dock with for extended field operations and patrols.
The tail of the Warden has a plaque with the name of the vessel prominent and presumably listing the lost crew of the Constitution; Matteus, Daragh, Garnet, Frej, Deven, Kilian, Jemmy, Donald, Clifton, Sarah, Juan, Richard, Maya, Evelyn, Ildar, Nicodemus, Matthew, Valefor, Alteran, Falnore and Inboots.

This ship became the main transportation vessel of the base with a view, and proved invaluable to the team. It was this vehicle that Shack used to save W4sted when he fell off an antenna tower, and then Morph when he was chased by the Grey suit.
At some point between seasons one and two, it was severely damaged and taken to the base-in-a-lake with multiple components missing, out of action. Captain Shack uses the ship as a bedroom as his room was not finished before they were forced underground.

In Episode 8, "Fix It On My Own", Shack eventually repaired the Warden with parts from the ultralight, though some unusual modifications were made to the ship, including a dorsal hatch for emergency egress. Some of these design changes do appear to have impacted the craft's weight balance when landed, making it potentially unsafe for future landings on the lake surface, but so far in-flight performance appears unaffected.
