Battleship was a name widely used for types of capital ship. Often, it was reserved as a term for the largest and strongest warships in a navy, broadly comparable with dreadnaught, but sometimes, smaller vessels in the same navy were described as performing the duties of a peace-keeping battleship. At times, it was synonymous with "warship" and simply described larger combat ships.
Even in the Pre-Republic era, large capital ships like the titanic battlecruisers that served in the navy of Xim the Despot were counted on to turn the tide of any battle.   Some of the earliest Old Republic era battleships and battlecruisers belonged to the planetary or sector naval forces of such worlds as Coruscant, Alsakan, Corellia, and their respective allies within the Core.  Throughout the course of the Alsakan Conflicts, squadrons of great and massive battleships were described to be the guardians of the Core worlds.  The prevalence and effectiveness of these larger capital ships varied depending on the technology and the prevailing strategies of the day. 
One of the known battleship classes introduced around the year 10,000 BBY, were vessels created in imitation of the long-running planet buster Kumauri Battleship line. This trend culminated with the Cal-class battleship, which was popular with several governments, most notably the Galactic Republic. These battleships were used to intimidate or destroy hostile civilizations, as the Republic aggressively expanded outward into the Galaxy. They were also effectively used as terror weapons during the Tenth Alsakan Conflict. 
After the Waymancy Storm of 7,811 BBY, the Republic slowly incorporated new technologies like the squintpipe process, which led to greatly improved turbolasers.  By 7,500 BBY, new breakthroughs in armor, shields, hyperdrives, and power generation ushered in a golden age of warship production. Larger capital ships would once more become the mainstays of the Republic military, its individual private sector fleets, as well dominions and kingdoms located beyond the Republics boarders.  This battleship era would only come to an end in 2,500 BBY due an economic downturn, which led to fleets being largely comprised of smaller cruisers. 
During the Great Sith War and the Mandalorian Wars, the Mandalorian factions used Kyramud-type battleships in their fleets. The Republic maintained fleets of large, blocky battleships that slowly became outdated and replaced. The Mandalorian Wars saw the Galactic Republic constructing and fielding the Inexpugnable-class tactical command ships which were sometimes referred to as "battleships."
In the final stages of the New Sith Wars, the term "battleship" for capital ships like the corsair battleship, fast-moving vessels which, along with starfighters, served in a picket/attack role, and provided support for other warships like Sith Destroyers and Hammerhead-class cruisers.
Clone Wars and beyondEdit
The "battleship" designation was again used by the Trade Federation for the militarized version of their LH-3210 cargo freighter. Though very large ships, and at least sometimes heavily shielded, the original militarized version of these ships was more of a starfighter carrier and battle droid assault ship than a combat warship, with a relatively light defensive armament of quad laser cannons. Later versions used during the Clone Wars, however, lived up to the "battleship" designation with a massive armament of turbolasers. During the Clone Wars, the Republic also faced the threat of the battleship Malevolence, Grievous's flagship and the strongest vessel in the Separatist fleet.
Cruisers and battleshipsEdit
During the Clone Wars and Galactic Civil War, ships such as the Venator-class, Victory-class and Imperial-class Star Destroyers could be referred to as either "battleships" or "peacekeeping battleships".
At the same time, the Venator-class was also contrasted with battleships in the Republic fleet, for which they acted as escorts. Little else is known about these battleships, except that they were heavier in some sense than "medium-weight" warships like the Venator-class. This would be mirrored in the Imperial Navy, with Star Destroyers of the day acting as escorts for larger vessels, like Star Dreadnaughts.
During the Galactic Civil War, the Imperial Navy described ships bigger than Imperial Star Destroyers as its largest battleships, built for the Imperial Navy by shipwrights like Kuat, Rendili and Loronar.
In the Alliance to Restore the Republic, the Mon Calamari MC80 Home One type Star Cruiser Home One served in a battleship role for the Rebels, In the Rebel Alliance and the New Republic, at least one model of Corellian gunship, could be described as a "battleship" or a "ship of the line".
Known battleship designsEdit
Throughout the course of the early Alsakan Conflicts the Core worlds were defended by squadrons of great battleships. Alsakan used these warships, along with their battlecruisers such as the Atgeir-class, for the purposes of home defense. Alsakan and their Axis allies possessed massive battleships even up until the Seventeenth Alsakan Conflict, where they were defeated by more advanced long range Corellian frigates. The class name, size and power of these battleships remain unknown. 
The Cal-class was a 3km long cylindrical battleship derived from the Kumauri Battleship design, and last in this line of battleships. Like the others, it was armed with a Mass-driver cannon, which was made obsolete with the development of stronger planetary shields.
The CGS Dreadnaught was a 900 meter long battleship that served in the Republic Navy at some point prior to the Great Sith War. By this time it was obsolete and most ships were scrapped.
Throughout the course of the early Alsakan Conflicts the Core worlds were defended by squadrons of great battleships. Corellia still possessed massive battleships at the start of the Seventeenth Alsakan Conflict, but they were quickly rendered obsolete by a new class of advanced long range frigates. The class name, size and power of these battleships remain unknown. 
The Corellian Dreadnaught was built by Corellia in secret in the lead-up to the Second Galactic Civil War. Three of these blue, oval battleships fought in the conflict, wrecking many ships before being destroyed.
This Sith battleship was a warship used during the New Sith Wars.
Throughout the course of the early Alsakan Conflicts the Core worlds were defended by squadrons of great battleships. Though Coruscant preferred smaller and more nimble warships, they were still known to produce large capital ships as well like the Gilagimar. Coruscant possessed massive battleships even up until the Seventeenth Alsakan Conflict, where they were defeated by more advanced long range Corellian frigates. The class name, size and power of these battleships remain unknown. 
The Sith-built Derriphan-class was the primary battleship of the Sith Empire. It was used during the Great Hyperspace War, where the ships were defeated by Republic designs. One was used as Exar Kun's command ship during the Great Sith War and more were built by the Empire ruled by Darth Revan and used as picket ships, against Republic frigates.
The Dreadnaught-class cruiser was one of the first designs made as part of a return towards heavier weapons-platforms in Republic Navy fleet doctrine. Despite its classification, the class was frequently referred to as the Rendili Dreadnaught and had a long career thanks to its heavy armor, which made many factions favor the ship even after it became outdated. The class was even produced by private companies in the Outer Rim, as trade barriers in the time before the Clone Wars barred rimward planetary governments from buying heavier material and warships from the Core.
The 17,5km long Eclipse-class was one of the largest and most heavily armed warships in galactic history. Shaped to resemble sea-going naval vessels of ages past, the black warships were infamous among New Republic personnel, particularly due to their superlaser main armament, lining the main dorsal hull.
The EX-F was an Imperial dreadnaught used as a testbed for various weapons.
The 19km Executor-class was a heavy battleship design built to command and coordinate fleets throughout a sector, and was armed with over 5,000 weapons-systems.
The Inexpugnable-class was a heavy warship used during the Mandalorian Wars, 3.1km in diameter. It could coordinate up to 64 smaller cruisers, but had several shortcomings, which were hoped to be solved by the production of the Centurion-class battlecruiser.
The Invincible-class was among the largest warships of the time of its construction and was classified both as a "dreadnaught" and a "heavy cruiser". At 2,011 meters, the cylindrical dreadnaught was covered with weaponry and heavy armor. Later, it was used as a picket ship by the Republic and Corporate Sector Authority, and had several shortcomings compared to newer designs.
The Mandalorian-made Keldabe-class had a design reminiscent of Mandalorian battleships of eras past, and was used by several fringe parties.
The Kor Chokk was a battleship-analog usually 8,180 meters in length, that looked similar to a collection of spheres consisting of various parts, grafted together after each won battle. They moved little in battle, but were equipped with many Yaret-Kor cannons. These ships fought in the Yuuzhan Vong War.
The Koros-Strohna were the huge colony vessels which the Yuuzhan Vong travelled in between galaxies. They were also used as heavy carriers and battleships, and were on average 10km in diameter.
The Empire commandeered the space construction facilities of Loronar for the purposes of assembling some of the largest battleships fielded by the Imperial Navy, along with other special weapons platforms. The class name, size and power of these battleships remain unknown. 
The Lucrehulk-class was a Trade Federation battleship with a 3km-long diameter converted from an existing freighter design. It carried armies and fighter squadrons and was heavily armed by the Separatists during the Clone Wars, being covered with gun batteries.
The Mandator-class was one of several designs preceding the Executor and Eclipse classes, built for the defense of the Kuat Sector, and later the Republic Navy during the Clone Wars.
The Home One type Star Cruisers, of individual designs, were used as battleships and command ships of the Mon Calamari self-defense forces, which later joined with the Rebel Alliance.
The Empire commandeered the space construction facilities of Rendili for the purposes of assembling some of the largest battleships fielded by the Imperial Navy, along with other special weapons platforms. The class name, size and power of these battleships remain unknown. 
This type of battleship was used as the main capital ship during the Great Sith War, participating in the Battle of Koros Major.
This heavy command ship was a predecessor of the Inexpugnable-class and fought during the Great Sith War.
The Sovereign-class was a mass-produced, compact version of the Eclipse design, at 15km in length. All known hulls were destroyed during the fall of the resurrected Emperor.
The Strident-class was a heavy warship made to complement the Mon Calamari-made Viscount-class Star Defenders in the final years of the New Republic.
The Subjugator-class was a heavy cruiser design used by the Separatists during the Clone Wars. Despite its classification, it eclipsed pre-war battleship designs used in the same navy and was often referred to as a battleship in its own right. It was infamous for its heavy ion cannons that were capable of disabling entire fleets of mainline Republic cruisers.
The Uro-ik v'alh was a oblong battleship design averaging 2,240 meters in length. It was used by the Yuuzhan Vong during their invasion of the galaxy.
The 17km long Viscount-class represented a new direction of the New Republic Navy, of heavy dreadnaughts that could withstand an assault by Imperial Remnant Super Star Destroyers. Although they rarely saw action against rogue Imperial forces, their value became apparent against the Yuuzhan Vong.
Behind the scenesEdit
In real life, the term "battleship" emerged with a precise meaning in the late nineteenth century, as an abbreviation of "line-of-battle ship". It denoted a ship that could fight in the "line of battle", the main fleet formation. The early battleships were contrasted with cruisers, which while at this time were similar in size and speed, but were designed for longer-range patrol missions, and carried less armor. Over the following decades, cruisers became faster, with more speed but less armor than a battleship.
The term dreadnaught (or in UK English, "dreadnought") became synonymous with "battleship" after the introduction of the revolutionary "all-big gun" battleship HMS Dreadnought in 1906. Overnight, all battleship classes prior to HMS Dreadnought were made obsolete, and two modern eras in battleship history would later be considered: Classes made before HMS Dreadnought were referred to as "pre-Dreadnoughts" while classes made afterwards, based on its design-principles, were referred to as "Dreadnoughts". However, this was not a fixed nomenclature, and didn't replace the term "battleship" (for instance, the US Navy referred to its largest ships as Battleships: ).
Alongside the dreadnaught, a type of large cruiser with a similar armament of heavy guns was introduced, called the battlecruiser. These retained the traditional of less armor and greater speed, but they quickly came to be perceived as closer cousins to Dreadnoughts than to normal cruisers, a situation that was formalized in the international naval treaties after World War I, which limited the size of cruiser guns.
In the twentieth century, battleships were often only slightly larger than contemporary cruisers, even the limited post-WWI types, and usually smaller than battlecruisers; but they were much heavier in tonnage, due to their massive armor.
The SW galaxy diverges somewhat from the real-world terminology by having a mix of "battleships" and "dreadnoughts" in the same cultures and eras.
