A Sentinel-class landing craft, also known as a Sentinel-class shuttle, Sentinel assault shuttle or Imperial landing craft, was a large-scale troop transport utilized by the Galactic Empire. During the early stages of the Galactic Civil War, Imperials such as Agent Alexsandr Kallus and the Grand Inquisitor utilized these transports to either deploy stormtroopers or to travel to a planet. Imperial Star Destroyers carried these shuttles.
Designed by Sienar Fleet Systems in the shape of its cousin, the Lambda-class T-4a shuttle, this larger, more spacious shuttle was primarily used to ferry a complement of 75 stormtroopers into battle—55 more troops than the Lambda-class. The ship featured three wings: one stationary center foil and two articulated flanking wings. The landing craft also had shielding strong enough to be able to withstand several hits from a Quasar Fire-class cruiser-carrier’s turrets. They could also be modified with special containers carrying vehicles.
The shuttle also had two spotlights at the front of the craft. It had several entry points, including a front ramp, a rear ramp, and doors to the side. The interior of the ship had a main passenger section and a cockpit. In the passenger/cargo area, there were benches and harnesses on each side with a ladder to the side of the front ramp leading directly to a hatch for cockpit access. The cockpit section had four seats. The shuttle could also feature a refresher on the opposite side of the ladder.
