Sienar Fleet Systems TIE Fighter v3

Note: This pack now contains the A New Hope version of the TIE Fighter, you can either select one or the other but not both.

Sienar Fleet System's TIE (Twin Ion Engine) fighter is the clearest symbol of the Imperial Navy's control of space. TIE Fighters are present aboard even the smallest Imperial cruisers and are stationed at starports and garrison bases across the galaxy, an ever present reminder of the Empires might.

Tie fighters are short range ships whose most distinguishing feature is the pair of dominant solar arrays wings mounted on either side of a small, spherical command pod. The TIE fighter presents a small target from the front and back, and it's incredible manoeuvrability makes it difficult to hit in combat.

One TIE Fighter may be vulnerable to attack and may be easily destroyed, but for every TIE that is defeated, thousands more will rise up. In battle, an Imperial cruiser can arrive near an enemy ship and launch all of its TIE's before Rebel gunners have a chance to respond. TIE fighters are used for planetary and cruiser defence as well as in assaults against Rebel, pirate, and alien vessels.

Sienar Fleet Systems TIE Interceptor v3

This short-range fighter was first manufactured soon after the Battle of Yavin, and became abundant by the time of the Emperor's fall. It is faster more manoeuvrable, and far more lethal than the standard TIE fighter.

This Interceptor uses the standard TIE cockpit, drive pod, and wing braces. The solar collector panels have been elongated and bent, providing extra power while not limiting the pilot field of vision. The solar panels appear to be "dagger-shaped", making the interceptor far more intimidating while giving it a smaller profile, making it harder for opposing gunner to target.

For weaponry, the Interceptor has four laser cannons, one at the end of each solar panel. Advanced targeting software gives the pilot greater fire accuracy even during complex manoeuvre's. While the Interceptor does not have a pair of laser cannons below the pilots compartment, the cannon hardpoints is still in place and additional cannons could be mounted there if technicians could find the room for additional power generators.

Sienar Fleet Systems TIE Bomber v3

The TIE Bomber was the Empire's most common dedicated bomber. While slower and less manoeuvrable than standard starfighters, these bombers provide excellent "surgical strike" potential against ground and deep space targets.

TIE Bombers have double pods and elongated solar panels. The starboard pod holds the pilot's compartment as well as flight computers, communications, and life support. The port pod contains the forward and main ordnance bays as well as the targeting and delivery systems.

The TIE Bomber's weaponry includes high yield proton bombs, guided concussion missiles, orbital mines, and free falling thermal detonators. Depending on the mission configuration, TIE Bombers can carry eight concussion missiles, or four proton torpedoes in the forward ordnance bay. The main ordnance bay can carry eight more concussion missiles, four additional proton torpedoes, eight proton bombs, six orbital mines, or sixty four thermal detonators. Two front firing laser cannons are placed between the two pods providing protection from enemy ships.

Sienar Fleet Systems TIE Avenger v3

An advanced, hyperspace-capable starfighter is the direct result of advancements developed for Darth Vader's TIE Advanced X1 prototype.

It is sometimes nicknamed "TIE Advanced", but this is improper terminology because it applies equally to other, completely distinct models like Lord Vader's TIE X1. Developed prior to the Battle of Hoth and used extensively in unpublicised campaigns against mutinous and corrupt elements within the Imperial Navy. Deployed only with elite and ultra-loyal fighter units, due to its enormous expense. Production declined after Palpatine's fall, for economic reasons.

For weaponry, the Avenger has four laser cannons, one at the end of each solar panel. Advanced targeting software gives the pilot greater fire accuracy even during complex manoeuvres. Two general-purpose warhead launchers are fitted either side of the cockpit compartment carrying two missiles each.

Sienar Fleet Systems TIE Defender v3

Note: This pack now contains the TIE Defender MkII the missile chambers on the Mk II have them placed on the outside of the cockpit pod, you can either install one or the other but not both.

The TIE Defender was a prototype Imperial fighter that was developed shortly before the Battle of Endor. After initial testing, which was believed to be personal supervised by top Imperial Navy commanders, the TIE Defender was deployed to a small number of elite TIE wings. Only a few key personnel in the Navy command knew that the ship was used to defeat rogue Imperial Admiral Zarrin, who had planned to depose Emperor Palpatine.

The vessel represented a radical departure from conventional TIE designs and featured three sets of solar collection panels mounted at equilateral points around the fighters main hull, while keeping the standard cockpit pod. At over 300,000 credits per unit,it was more than five times as expensive as a standard TIE Fighter.

The TIE Defender features four laser cannons and two ion cannons, which can be fired independently for multiple targets or fire linked for a concentrated assault. Rounding out the TIE Defender's weaponry are two missiles launches which can each be equipped with four proton torpedoes and concussion missiles. For defence, the TIE Defender has a pair of Novaldex shield generators.

Sienar Fleet Systems TIE Advanced X1 Prototype v3

Lord Vader's personal fighter belonged to this class of long-range (hyperdrive-capable) fighters. It is sometimes regarded as a custom or deluxe design, but this may be just a figment of hindsight, since this class became a source of inspiration for the later, famous Interceptor and Avenger models. This heavy fighter may actually have been a commonplace long-range fighter design used throughout much of the history of the Empire: according to blueprints, the star destroyer Imperator (the first of its class) originally carried a number of unipod bent-wing "TIE assault craft".

The "customisation" of Vader's personal TIE might actually extend no further than its provision of shields (This is a distinctive feature; most TIE fighters are unshielded and rely on superior piloting skill and tactical advantage.) Alternatively, the modification might involve the partial removal of shields or targeting systems, since Vader's excellent piloting skills are augmented by his mastery of the Force. Perhaps the speed or the power of the weapons have been enhanced. Perhaps the customisation involves life-support in the cockpit; Vader's fighter might optionally provide him with an environment similar to that created in his hyperbaric meditation chambers.

In any case, this fighter is significantly faster and more manoeuvrable than its mass would suggest. Four thruster nozzles are placed in two pairs above and below the extended tail of the fighter. This section, containing a shield and hyperdrive units, blocks the usual cockpit rear viewport. Therefore a realistic holographic viewscreen is mounted behind pilot seat to mimic the rear window found in ordinary TIE starfighters. Judging by cockpit interior details, the main hatch is still at the rear of the ship, but the mechanism by which it opens must be more complex than for TIEs with a simple unadorned hull pod.

The wing pylons are thicker than usual, and there are large holes in their front faces. Through these gaps, a set of curved pipes can be seen. The pipes run in the same general direction, from the main hull towards the wings. These probably carry outbound coolant. The partial exposure of these pylon pipes to space may be a modification to further improve the removal of excess heat.
