I'm starting with Season One, which I wrote a lot of technical details for that I later went back on and redid because I fucked up so badly. Do not take anything in the following passage as canon.
SGC ships and equipment.odt
SHIPS:
Athena-class battlecruiser BCH-305/BC-3
Length: 535 meters
Span: 268 meters
Height: 143 meters
Complement: 10 F-302 or F-306, 4 A-307, 1-4 SG teams
Armament: 1 main railgun, 6 heavy railguns, 38 light railguns, 8 point-defense missile pods, 36 VLS tubes
Developed in parallel with the Daedalus class, the Athena-class battlecruiser is almost twice the size. Though it carries a small complement of fighters, its main strength lies in the massive main railgun and heavy naquadah-enhanced nuclear missiles. The Athena-class is well equipped for combat against fighters and other capital ships, but less so for ground action, as they only carry a few SG teams and no ground vehicles. Like the Daedalus and Prometheus class ships, the Athena-class is equipped with an Asgard hyperdrive, beaming technology, energy shielding, and primarily crystal-based circuitry.
Normandy-class assault carrier SCA-308/SC-1
Length: 602 meters
Span: 432 meters
Height: 245 meters
Complement: 40 F-302 or F-306, 18 A-307, 8 M301 tanks, 16 M302 troop carriers or M303 AA vehicles, 40-150 marines
Armament: 2 heavy railguns, 22 light railguns, 8 point-defense missile pods, 1 ground bombardment cannon
The Normandy assault carriers are designed primarily for planetary assault and secondarily for fighter engagements against enemy ships. Though poorly equipped for ship-to-ship combat, the Normandy more than makes up for it with fighter and ground forces. It is equipped with beaming technology to land troops, but the A-307s can be used as a backup.
Enterprise-class supercarrier SC-2
Length: 1267 meters
Span: 690 meters
Height: 315 meters
Complement: 100 F-306, 32 A-307, 2 C-308, 24 M301 tanks, 36 M302 troop carriers or M303 AA vehicles, 100-450 marines
Armament: 8 heavy railguns, 74 light railguns, 32 point-defense missile pods, 48 VLS tubes
Twice the length of the Normandy-class assault carriers and twice as wide as the length of the Prometheus, the Enterprise is the largest ship ever built by the Tau'ri. However, it is still dwarfed by even a Wraith Cruiser. Nevertheless, the large fighter and marine complement makes the Enterprise worth the expense. It is equally well equipped for both planetary assaults and ship-to-ship combat.
C-308 Multipurpose vessel
Length: 18 meters
Span: 11 meters
Armament: 4 light railguns, Star Streak /S missile system
Somewhere between a fighter and a ship, the C-308 is an Earth-built design similar in purpose to an Al'kesh and a Tel'tak all rolled up into one. Equipped with four light railguns and the Star Streak missile system, the C-308 can also beam nukes into the proximity of enemy ships, though it must get close to do so. The C-308 is highly maneuverable and equipped with a decent hyperdrive, powerful shields for a ship of its size, and of course transporters. It is a small design with an upper crew deck and lower cargo deck, engine access at the back of both decks.
FIGHTERS/GROUND VEHICLES:
F-306/F-2
Length: 12 meters
Wingspan: 12 meters, 6.6 meters folded
Crew: 2
Armament: 2 rapid-fire railguns, 1 internal weapons bay, external hardpoints
A replacement for the F-302, the F-306 is smaller and more dart-shaped in comparison. It is a similar multirole fighter, two person, equipped with sublight but not hyperdrive engines. The F-306 boasts improved maneuverability as well as upgraded armament. It has two railguns as well as hardpoints for fighter-to-fighter, ground-attack, or anti-ship nuclear missiles. Propulsion consists of two pulse detonation engines and an Asgard thruster. The F-306 can fold its trapezoidal wing and fly through a Stargate, though it is not safe to do so at high speeds. Despite being superior in almost every aspect to the F-302, it is lighter and smaller, mostly due to the omission of the useless hyperdrive unit.
A-307/A-3
Length: 16 meters
Span: 6.6 meters
Crew: 2
Passengers: 2 jump seats, 8 in convertible bay
Armament: 20mm Gatling gun, configurable weapons/cargo bay
Often compared to a helicopter, the A-307 is a multipurpose VTOL spacecraft. It can be configured to carry cargo, anti-ship weapons, or to land troops. Though normally armed with only a 20mm Gatling gun in the nose, the A-307 is capable of taking missiles, railguns, or even energy weapons. The A-307 is equipped with shields of moderate strength and a short-range hyperdrive. The A-307 is almost unique in having no wings at all, being designed to fit through a Stargate. It uses anti-grav units to stay in the air and an Asgard thruster for propulsion.
M301 Main Battle Tank
Crew: 2
Passengers: 2
Armor: 50-200mm trinium, Asgard energy shield
Armament: 1 main railgun, 1 12.7mm Gatling gun (coaxial), 1 .50 caliber machine gun on automated mount or Star Streak/G launcher
Initially, the M1A2 Abrams tank was chosen for offworld use. However, it was ultimately decided that though costly, the development of a tank specifically for offworld engagements would be necessary. The M301 is equipped with a railgun and a Gatling gun on the turret, energy shielding, and a naquadah based power plant. A Star Streak/G launcher can be substituted for the machine gun. The M301 has a two-person crew but can carry up to four people. Part of the new generation of combat vehicles, the M301 is sized to fit through a Stargate, fully amphibious, designed to operate for weeks without refueling or maintenance, and highly automated with interlinked communications systems.
M302 Armored Troop Carrier
Crew: 2
Passengers: 8
Armor: 10-75mm trinium, Asgard energy shield
Armament: 1 rapid-fire railgun, Star Streak/G missile system
Based on the chassis and powerplant of the M301 tank, the M302 troop carrier has less armour and weaker shielding. It was designed a smaller railgun that can fire rapidly, similar to those on the F-306. However, some early production models were fitted with a Bushmaster cannon like that on a Bradley as railguns were in short supply. The M302 can accommodate eight armoured troops as well as a driver and gunner. The M302 troop carrier can also be equipped with the Star Streak/G missile system. As with the M301 and M303, the M302 is designed to fit through a Stargate.
M303 Anti-Aircraft Vehicle
Crew: 2-3
Armor: 10-75mm trinium, Asgard energy shield
Armament: 2 rapid-fire railgun, Star Streak/G missile system
Based directly on the M302, the M303 removes the passenger compartment to accomodate VLS tubes for Star Streak/G missiles. It is also equipped with a twin-railgun turret. Thanks to advanced automation, the M303 can be operated by a driver and a gunner, though it can carry an additional gunner/electronic warfare officer.
ORDINANCE:
Star Streak G/F/S missile system GSM-1/SFM-1/SDM-1
A completely new missile designed to meet the demands of space and ground combat against transatmospheric fighters. The Star Streak missile system is equipped with a naquadah warhead and naquadah-catalyzed fusion thruster. The "G" variant has limited ground-to-orbit capability but is designed for destroying fighters while they are in the atmosphere, and is small enough to be packaged into a semi-person-portable launcher (it is too heavy and awkward for a normal human but soldiers wearing Aegis powered armor can use it with no problem). The "F" variant is used for fighter-to-fighter combat, and the "S" system is designed to be used for short-range point defense on capital ships. Star Streak missile variants are different only in programming and thruster systems.
Sparrowhawk MRNM/FLNM
A multi-purpose nuclear missile equipped with a naquadriah-enhanced nuclear warhead. The MRNM version designed for ship-to-ship combat is equipped with a more powerful fusion engine than the smaller FLNM fighter-launched version. The Sparrowhawk is less powerful than the Hades missile but can be fired from existing launchers or fighters. It is estimated that a handful could destroy a Ha'tak vessel, provided they all detonate.
Hades LRNASM
Launched from the missile tubes of capital ships, stations, and, when fitted with a booster, ground-based launch stations. The Hades missiles are designed for long-range nuclear strikes, usually on ships. A Mark X warhead, which is actually slightly less powerful than a Mark IX, provides the nuclear capability. The long-range capability is provided by a powerful and advanced sublight engine as well as a miniature naquadriah based hyperdrive. Usually naquadriah is too unstable, but a sacrificial power buffer stabilizes it enough for (relatively) short hops on a disposable asset. The Hades missile sometimes drops out behind a ship's shields or even inside the ship, making it extremely effective. Unfortunately, the missiles are large and heavy and even an Athena-class battlecruiser cannot carry many.
SAMRAAM and SASRAAM
Adapted from air-to-air missiles, the SAMRAAM medium range and SASRAAM short range missiles are a stopgap measure until the Star Streak is fully in production. A new sensor and computer package is fitted, but the warhead and thruster remain the same.
PERSONAL EQUIPMENT:
Aegis Mark 1 personal protective system
Based off both Earth projects and reverse engineered Kull armor, it is a fully powered, all-threat protection system. It significantly increases the strength and speed of the wearer while providing them protection against energy weapons, projectile weapons, and CBRN agents. The Aegis is fully waterproof and airtight and has an advanced thermal regulation system. In addition to filters it has an independant air supply, for space, underwater, and oxygen-poor environments. The mark 1 suffers from some flaws, however. It is incredibly expensive to produce, must be custom-fitted to the wearer, and the shields usually drop after one hit.
Aegis Mark 2
Based off the Aegis Mark 1, the Mark 2 incorporates more Asgard technology than its predecessor. The new shields are capable of taking several hits before failing and a moderately effective inertial dampening system has been integrated. The air supply has been increased to two hours, using air regeneration systems similar to those on capital ships. The improved armor is produced using Asgard matter replication systems. Though not integrated, a holographic projection system can be equipped, allowing active camouflage and deception tactics.
SCAR-L (M116) and SCAR-H (M117) Assault Rifles
The SCAR-L and SCAR-H are gas action assault rifles chambered in 5.56mm and 7.62mm respectively. SGC variant SCARs are equipped with 30 round magazines and smart-linked scopes.. The majority of SG teams are equipped with SCAR-H rifles in the standard configuration (smartlink scope, 16" barrel). SCAR assault rifles are adaptable- they can mount longer or shorter barrels, different sights, and a 40mm grenade launcher. C-mags are available for both the 5.56mm (100 rounds) and 7.62mm (60 rounds) rifles.
M91 Submachine Gun
The M91 is a blowback action submachine gun chambered in 5.7mm. It is equipped with a forty round magazine. Like the SGC-issue SCAR, it comes standard with a smart-linked sight with ammo counter, fire mode/safe display, and 2x magnification. As standard, it has a 10 inch barrel, folding stock, and safe-single-full trigger group. However, the M91 can be configured with a shorter barrel, fixed stock or no stock at all, different trigger groups, and large-capacity C-mag. One option not available is a silencer- a silenced MP5 variant is used for covert missions.
Five-seveN Pistol
Instead of developing a new pistol, the existing Five-seveN was adopted. It fires the same 5.7mm ammunition as the P90 and M91. The AESF variant comes standard with a 20-round magazine, both standard sights on top and smart-linked ones underneath, and a 5-inch barrel. The Five-seveN is made mostly of polymers and uses a delayed blowback system. The barrel is threaded for a detachable silencer, which is almost always carried by ground troops.
M107 Sniper Rifle
The M107 is a .50 BMG semi-automatic sniper rifle. At 57 inches long and weighing in at 30 pounds, it is very heavy and awkward. The Raufoss Mk 211 standard in the AESF is capable of penetrating armor and destroying vehicles, aircraft, and multiple troops. It is one of the few reliable methods of killing a Kull Warrior. The SGC variant is equipped with a telescopic smart-linked sight. Though usually fired from a bipod or rigid mount, it is possible to fire the weapon without either while still retaining some degree of accuracy.
M240 General Purpose Machine Gun
The M240 was chosen as the AESF's standard machine gun. It fires the same 7.62 NATO round as the AR-1, but from a belt feed. The MG-1 is reliable, powerful and accurate. It is used for defensive or supporting fire. Usually used with a bipod or fixed mount, it can be fired from the shoulder or the hip as well.
Star Streak/G Launcher
Designed for destroying aircraft, the Star Streak can also be used against vehicles by simply switching software modes. Vastly superior to the Javelin and Stinger systems it replaces, the Star Streak uses a hybrid fusion thruster and partially crystal-based circuity. For target acquisition, the SS/G is equipped with an 8x scan/render scope capable of targeting beyond visual range and through obstacles. The controller smart-links to the user's armor, allowing quick targeting and firing. The biggest disadvantage of the Star Streak system is the weight. Even with Aegis armor, a soldier can only carry a handful of missiles.
M-699/GEW-1 Energy Projector
The X-698 was a heavy, cumbersome, and unreliable attempt at an energy weapon. It was quickly replaced by the M-699 (re-designated GEW-1), which incorporated Asgard technology, producing a lighter, more reliable weapon. The GEW-1 is capable of taking down a Kull with several shots and doing some damage to human-form replicators.
In addition to AESF-customized and AESF specialized weapons, several standard weapons, sometimes modified, are issued as required. These include the MP5SD silenced SMG, Desert Eagle .50 AE pistol, Javelin missile, M2HB .50 HMG, and numerous others.
