YSS-1000 Prototype Anti-Ship Spaceplane

YSS-1000 "Sabre"

The YSS-1000, or simply referred to as the Sabre was a starfighter used by the UNSC Defense Force during the Human-Covenant War. Its first known use was in Operation: UPPERCUT during the Fall of Reach.

Description
The YSS-1000 is a space-based fighter which can be launched vertically from a ground-based launch platform using a system of detachable multi-stage rockets to propel itself out of a planet's gravitational pull and atmosphere.

The fighter's armament includes twin autocannons as well as missile pods with locking abilities. The Sabre also possesses energy shielding technology. The Sabre is capable of snap rolls and its targeting computer can identify enemy contacts from a distance, as well as show the distance to a target.

History
The Sabre was the result of the "Sabre program", a top-secret UNSC project in which SPARTAN-B312 was involved at some point. Reach had multiple Sabre fighters stored in launch facilities on the planet's surface which would be used to reinforce the UNSC Navy, should they require assistance in battle. In addition, the orbital platform Anchor 9 had Sabres stored in its launch bays. SPARTAN-B312 and Jorge-052 of Noble Team used one of these vehicles to assist the Epsilon Eridani Defense Fleet in Operation: UPPERCUT during the Fall of Reach, in which multiple Sabres were deployed to defend Anchor 9.

Gameplay
The Sabre is playable in the space combat segment of the Halo: Reach campaign mission Long Night of Solace.

Like other vehicles in the Halo games, the Sabre is piloted from third-person view. The Heads Up Display, located near the center of the screen, shows the weapon currently in use, thruster heat, as well as the hull and shield integrity of the Sabre. Enemy ships are identified by type and highlighted with a distance marker once the targeting reticle is moved on them. The HUD is slightly different depending on the weapon used at the time.

Roll and direction change is controlled by the right thumbstick, while the left stick controls speed. The Sabre also has a boost function, which uses its wing-mounted thruster engines. This fills up the thruster heat bar which needs to cool down after continuous usage. A variety of maneuvers such as Aileron rolls (often mislabeled as 'Barrel Rolls') and Immelmann turns can be performed by using the left bumper. The weapon in use can be switched between the machine guns and missiles with the Y button. The machine gun has an additional reticle leading the target, and the missiles can lock-on to enemy ships.

Trivia

 * Like the UNSC's Longsword-class Interceptor and Shortsword-class Bomber, the Sabre is named after a type of sword.
 * Although Bungie experimented on implementing the Sabre into multiplayer, it will only appear in the campaign due to balance issues.
 * The Sabre launch sequence in Halo: Reach is an homage to NASA's Space Shuttle program in both components and angles used for the cinematic. Several angles of the Sabre's launch sequence use similar camera angles seen during shuttle launches, and the on-board cameras are used on the shuttle to examine foam loss on the external tank. The design of the Sabre's own tank is somewhat based on the external tank used on the shuttle.
 * At the E3 interview, it is stated that the Sabre was the UNSC counterpart to the Seraph.
