Picket Fleet The Picket Fleet was the space navy of the Corporate Sector Authority . Organization . The Picket Fleet was part of the Corporate Sector ' s Security Division , and as such , its primary role was policing against non - military opponents . It was organized to take on smugglers and pirates , and to support the suppression of planetary unrest , and the ships it used reflected this mission . Larger warships . The Corporate Sector devoted no significant resources to the construction of large warships , preferring instead to acquire them from abroad . Before the Clone Wars , the Picket Fleet had equipped itself with new Dreadnaught Cruisers from Rendili StarDrive , but in the long term , their usual procurement policy was to acquire large , old ships that were being discarded by other navies . These were almost always slow and obsolescent , but the sheer quantity of firepower they could carry would overpower most of the Picket Fleet ' s paramilitary opponents . As Palpatine consolidated and modernized his military forces , whole fleets of older warships became available , ranging from ancient heavy cruisers that had served the Old Republic centuries earlier , through veteran Star Destroyers from the Clone Wars , to former Separatist warships . For many years , the core of the Picket Fleet was a force of 520 " Victory I " - class Star Destroyers purchased from the Imperial Navy . Other veteran warships from the Clone Wars were added as available , such as a force of six " Recusant " - class light destroyers . A number of " Lucrehulk " - class battleships and Core Ships were also acquired at this time by the Corporate Sector . Perhaps the most distinctive warships in the Picket Fleet were a number of large , ancient " Invincible " - class Dreadnaught Heavy Cruisers , originally built for the Old Republic . These were already around three thousand years old at the time of their acquisition , but their large hulls could carry many weapons and troops , and their simple systems made them easy for Espo crews to operate . By the time of the Yuuzhan Vong War , however , only a few of these old ships remained . After the end of the Galactic Civil War , many warships were once again surplus to the needs of other naval forces , and the Picket Fleet acquired a large number of these , notably including one Imperial - class Star Destroyer . In the years , after the Battle of Endor , the Picket Fleet also made use of an Escort Carrier design , which may have been the 500 - meter Kuat Drive Yards design . Small cruisers and starfighters . The smaller ships used by the Picket Fleet , built in the Corporate Sector ' s own yards , were typically no larger than corvettes , although they were often referred to as cruisers . Other designations for smaller Picket Fleet vessels are known , however , including sloop and gunboat . The standard design for many years was the " Marauder " - class corvette . Originally developed by Republic Sienar Systems , the rights to the design were acquired by the Corporate Sector after it failed to make an impact in other markets . Alongside this , the Picket Fleet also used a militarized version of the Corporate Sector ' s locally - developed " Etti " - class light transport . Both these types were capable of carrying out the role for which they were built , but both were developed by the Corporate Sector without designing a warship class from the keel up . Throughout the Galactic Civil War , surplus Picket Fleet corvettes were sold to other fleets , in a reversal of the Corporate Sector ' s acquisition policy for larger warships . < ref name = " EaW / VotF " > " " has the Rebel Alliance using the " Marauder " - class design , while " Vision of the Future " has the Diamal acquiring a flotilla of the same ships in 19 ABY . < / ref > Also , vessels were sometimes built for export . By the time of the Second Galactic Civil War , the Corporate Sector ' s shipyards were building a new type of corvette - sized " cruiser " , " Cutlass " - class , which was used by the Imperial Remnant and probably also by the Picket Fleet itself . Some smaller Picket Fleet ships were acquired from outside in the same way as the larger warships . After the end of the Galactic Civil War , for example , a small number of military - surplus EF76 Nebulon - B escort frigates were purchased from other navies . The Picket Fleet also made use of starfighters . Like the corvettes , these were usually built locally , but sometimes using foreign designs . The standard Picket Fleet starfighter was the home - grown IRD and IRD - A , but other types were produced as well , such as the Mankvim - 814 light interceptor , a Techno Union design acquired after the Clone Wars , and constructed in limited numbers . The TIS Zeta 19 was a starfighter common in the hangars of Corporate Sector stations . Personnel . Recruitment patterns for the Picket Fleet paralleled the origins of its ships : the bulk of enlisted personnel were Corporate Sector citizens , but many of the Picket Fleet ' s senior and mid - level officers were recruited from other military forces , and particularly from the Imperial Navy , such as Baruche Sloane , Jona Grumby and Milo Phineas . The ranks used by the Picket Fleet were similar to those used in other naval services . Deployment . Typically , Corporate Sector warships operated individually . Sometimes , however , the Picket Fleet could deploy a sizable task force to seize control of a star system from a foreign fleet . One example of larger - scale operations of this sort occurred after the Battle of Endor , when a powerful Picket Fleet task force , led by the " Victory " - class Star Destroyer " Enforce " , intervened at Kirima .
