GA-TL1 Longsword

The GA-TL1 Interceptor/Strike Fighter, commonly known as the Longsword, is the main single ship of the UNSC Defense Force. It is capable of filling a variety roles, exclusively or simultaneously.

Development and service history
The Longsword, manufactured by Misriah Armory, was designed during the 25th century by Gov Aukland and Thomas Levesque, whose names inspired the GA-TL1 designation. Longswords saw service during throughout the Insurrection, such as during the nuclear bombing of Far Isle. Later, Longswords were deployed on the front lines of nearly every major engagement of the Human-Covenant War under both the Navy and the Air Force. Longsword Squadron Delta, assigned to the UNSC frigate Commonwealth, engaged Covenant forces during the Battle of Chi Ceti, the first space battle of the war.

Design
The GA-TL1 Longsword is designed primarily as a fighter, though it can also be used for interception, suppression, bombing, or direct attack. There are a number of variants of the craft, with some variants measuring 64 meters (210 feet) long and 75 meters (246 feet) wide, though some are considerably smaller. All Longswords feature a crew of four: a pilot, a copilot, a navigator, and a systems operator; the crew may be assisted by an onboard artificial intelligence.

While there are several noticeable external and presumably internal differences among variants, all Longswords share a common overall architecture. The craft features a wide, manta ray-like design with a rear-facing boom apparatus protruding from the center of the fuselage, similar to that of the B-65 Shortsword. The exhaust ports for the Longsword's twin fusion engines are also visible at the rear of the fuselage. The C709 variant features a large, diamond-shaped air intake underneath each wing, though these are much smaller on the C712 and possibly other variants, instead fitting flush with the fuselage. Furthermore, the C709 possesses a traditional non-polarized glass canopy, though other variants feature a much larger, black-polarized canopy.

Inside the Longsword is a small corridor leading to the rear, along with stairs and a higher corridor that lead to the cockpit. In the two corridors, there are several equipment lockers, along with two secondary crew stations. The cockpit contains the pilot's and copilot's stations, which include control interfaces and information readouts, as well as an AI holotank if present.

The Longsword can be remotely piloted, as was performed during the Battle of Chi Ceti in 2525.

Armament
The standard armament of the GA-TL1 is the M9109 50mm cannon. Some variants are armed with 110mm rotary cannons or a turreted 120mm ventral gun that can be retracted into the hull, though the latter is likely a secondary weapon. The Longsword can also accommodate any of several of supplementary weapon systems, including four ASGM-10 missiles, a variety of bombs, Moray space mines, or even a single ; when remotely piloted, the Longsword itself can be used as a deliver system for the Shiva warhead.

Variants
There are multiple variants of the GA-TL1 Longsword that are designed to perform specific functions, such as the C708, the C709, and the C712. However, these variations are not static; Longswords can be modified on a craft-by-craft basis to fit the needs of a given mission.

C709
The C709 variant is designed to apply force in exoatmospheric engagements and is armed with a 110mm rotary cannon. Despite its focus on exoatmospheric combat, the C709 features large air intakes and a non-polarized canopy.

C712
The C712 variant specializes in short-range atmospheric/exoatmospheric (A/X) strike runs. It can carry an assortment of missile and mine delivery systems. The C712 features a large, polarized canopy and integrated air intakes.

Trivia

 * Like the YSS-1000 Sabre and the B-65 Shortsword, the Longsword is named after a type of blade.
 * The crashed Longsword on the level Tempest along with background and cutscene-only appearances are only half as large as their original Halo: Combat Evolved appearance. The version in Tempest is too small to even hold a SPARTAN crewmember.
 * The Longsword's cabin is nearly as wide as that of an Airbus A320, a commercial airliner.
