E - Web heavy repeating blaster The E - Web was a heavy repeating blaster manufactured by BlasTech Industries . It was one of the most powerful repeating blasters in the Imperial arsenal , and had an optimum range of one - hundred and fifty meters with a maximum range of seven - hundred and fifty meters . The full name is Emplacement Weapon , Heavy Blaster , but many users shortened this to E - Web . The original weapon was designed in a joint effort with Merr - Sonn Munitions , which produced the predecessor to the modern E - Web , the EWHB - 10 . Members of the Stormtrooper Corps are trained to utilize the weapon , although its mass makes it being carried by a single stormtrooper impossible , mandating that it be operated by two stormtroopers : one for firing the E - Web , and another monitoring and adjusting the generator ' s power feed to prevent overheating . Description . The weapon was able to be broken down into parts and carried by a small crew of troopers making it fairly mobile , but had to be rigidly mounted in order to counteract the effects of its incredible firepower . It took a relatively long amount of time to set up , and required two crew members for optimal effectiveness . One crewer manned the gun , and the other monitored and adjusted the Eksoan Class - 4T3 power generator . Like many high - yield generators , the 4T3 was prone to overheating and potentially explosive overload , despite its advanced Gk3 Cryocooler cooling unit . Power was fed into the E - Web via a conduit that connects to the base of the TR - 62 Autocushion Tripod . The built - in comlink with automatic encryption allowed for secured communication with other units . The computerized fire control and targeting system included infrared and StarVision low - light enhancement for use in night combat . Overall , the E - Web can be transported and assembled for firing within a minute or less , although it will take up to ten minutes for its generator to reach full power . The long set - up time was the E - Web ' s primary limitation . If the 4T3 generator was " cold , " it could take nearly fifteen minutes for the crew to deploy the weapon , calibrate the generator and configure the targeting software . Some Imperial crews pre - charged the generator before use for faster set - up , but this made it prone to power surges . Thus , the second crew member had to carefully adjust power flow to prevent an overload . Imperial Snowtroopers on Hoth were able to set up and fire an E - Web in a matter of seconds in this fashion . A single soldier could operate the E - Web , but at greatly reduced efficiency . In such cases , the gunner chose a power generator preset mode , which greatly reduced the rate of fire , but kept the E - Web and its generator operating at safe temperatures . Its retail price was 8 , 000 credits , a small price to pay from the Empire ' s infinite coffers . Maintenance of the weapon required monthly disassembly , inspection , repair , and reassembly . E - Web upgrades . There were several upgrades to the E - Web on the market , including the F - Web and the EWeb ( 15 ) . The F - Web added a small shield generator that was powerful enough to block fire from small sidearms such as blaster pistols . The shield offered good protection , but it required a third crew member to operate . This model was used primarily in the Corporate Sector . The EWeb ( 15 ) was released the year after Emperor Palpatine ' s death . It offered improved fire control and targeting software . With the generator ' s auto configure setting , the weapon could be set up in less than five minutes . The cooling system was also upgraded to the advanced Gk7 Cryocooler offering increased power flow into the weapon without the risk of overheating . This allowed continuous fire for up to one hour . Many EWeb ( 15 ) units were equipped with a shield generator . The E - Web rifle was a portable version of the E - Web heavy repeating blaster . The E - Web itself had some modifications of its own , including a high - fire repeater setting and automated sentry turret modification kit . History . Pre - Clone Wars . The E - Web was used by Granta Omega in an attempt to murder Jedi Knight Obi - Wan Kenobi . The weapon overheated and exploded , severely wounding Omega . Clone Wars . The EWHB - 12 heavy repeating blaster was used by clone commandos as a distraction to infiltrate a Separatist nanovirus facility on Qiilura that was producing a nanovirus capable of killing all clones . It was also used in the Battle of Praesitlyn . Galactic Civil War . Stormtroopers set up E - Webs to defend backwater worlds . During the Galactic Civil War , Rebel Commander Luke Skywalker took control of an E - Web to shoot down an Armored Personnel Carrier carrying the captured defector , Tycho Celchu . Soon after , he took control of one on a CR90 corvette to eliminate boarding stormtroopers . The E - Webs also saw use at the Battle of Hoth in 3 ABY , in a battle on Geonosis , and the Mission to Cilpar . It was used on Tatooine in 8 ABY by stormtroopers trying to prevent the " Millennium Falcon " from escaping . Chewbacca blasted the troopers with an on - board laser cannon before they could set up the E - Web . Behind the scenes . The E - Web ' s first appearance in " Star Wars " canon was in . The E - Webs have appeared in LEGO form , both in real life and in " " . There are slight differences in this weapon ' s range presented in the " Star Wars Roleplaying Game Saga Edition Core Rulebook " that differ from the range as listed in the " The New Essential Guide to Weapons and Technology " . According to the Saga Edition , the optimum range is up to 75 meters and the maximum range is up to 750 meters .
