Imperial Navy/Legends



The Imperial Navy, also known as the Imperial Starfleet or simply the Imperial Fleet, was the military arm of the Galactic Empire charged with maintaining security in Imperial space.

At its peak, it fielded millions of warships and fulfilled Emperor Palpatine's will throughout the Galaxy.

After the defeat at the Battle of Endor, the Galactic Empire split up into warring factions led by warlords, and the Imperial Navy splintered along with it. While much of the remnants of the Imperial Navy were later reunited under impressive Imperial commanders, the military organization ceased to exist shortly after the death of Emperor Palpatine.

Specific responsibilities of the Imperial Navy included defending Imperial citizens from space-based threats such as pirates, smugglers, and other armed governments, enforcing Imperial will, and overseeing commerce through customs and blockade operations. The Imperial Navy also performed orbital bombardments, transported major ground force deployments, and supported them with space and aerial support.

The Imperial Navy conducted itself by the Imperial Naval Code, a set of martial laws and regulations created to guide the massive military organization. The vast majority of personnel in the Imperial Starfleet were male Humans, although some Human females and even other species were also in the service, such as Admiral Daala and Grand Admiral Thrawn.

Key ships of the fleet
The most recognizable symbol of the Imperial Starfleet was the Imperial-class Star Destroyer, although millions of starships of different designs and functions were fielded for various purposes and roles.

Most major capital ships during the height of the Galactic Empire were constructed by Kuat Drive Yards. The Corellian Engineering Corporation was also known to have supplied the Empire with gunships and corvettes (and possibly also large battleships and starfighter carriers). Other ship manufacturers supplied the Imperial Starfleet with support ships such as Carrack-class light cruisers, Lancer-class frigates, Strike-class cruisers, and escort carriers.

Education
Naval recruits first attended the Imperial Academy to gain the basis of their higher education and military discipline, and then continued their education at the Imperial Naval College, where Academy graduates received specific training on naval operations, combat, and command functions. Finally, non-commissioned officers and recent graduates of the Imperial Naval College could participate in a training program through the Imperial Navy Officers' School to focus on military customs and courtesies, military history, leadership, officership, deck command exercises, discipline drills, and other pertinent areas of education of potential officers. Upon graduation, trainees were commissioned in the Imperial Navy as Lieutenants.

Organization


The Imperial Navy used an overall strategy of focusing on capital ship firepower rather than starfighter superiority. This was reflected through the design of their starships, the formation of their naval units and the overall organization of the force. Regional, oversectorial and strategic military commands existed as well, but the details of their compositions is unknown.

Command
An individual command, a single starship, was the building block of the Imperial Starfleet. Achieving command of a starship, no matter its size, was point of pride in an officer's career. Officers commonly turned down impressive staff promotions in the hopes of receiving a ship command, although serving as a staff officer on a prominent starship, such as a squadron flagship, was often considered a fast track for promotion.

Line of battle
The most basic unit in the Imperial Navy was a line of battle, or simply a line. The Imperial Starfleet shaped four to twenty starships into lines, depending on the type of line. Commanded by a captain of the line, the line was the most amorphous level of organization in the Starfleet. The Imperial Starfleet Order of Battle outlined five types of lines: attack, heavy attack, reconnaissance, pursuit, and skirmish. Attack and heavy attack lines aggressively engaged enemy starships in combat, reconnaissance lines gathered intelligence of the disposition of enemy forces, pursuit lines chased and trapped retreating enemies, and skirmish lines harassed capital starships and engaged enemy picket lines.

In addition to the five types of lines, the Imperial Navy considered an Imperial-class Star Destroyer a line in itself. While an Imperial-class Star Destroyer may be able to act as an attack line and its compliment of starfighters as a skirmish line, the decision to give commanders the option to field a heavy cruiser as a line unto itself was more political than tactical. After a naval staff study suggested a Star Destroyer was the field equivalent of the smallest of naval squadrons, the Admiralty decided that, as there were more lines than squadrons, designating the Star Destroyer as a line unit would get them more Star Destroyers. The Admiralty's thinking prevailed.

Squadron


A squadron was the smallest independent operating unit in the Imperial Navy. Composed by several lines, a squadron was commanded by an admiral and ranged from 14 to 60 ships, depending upon the composition of the lines in the squadron. A squadron was the largest concentration of ships normally assigned to a single system. The Galactic Republic designated units of identical configuration as fleets. Those units were the total naval presence in a sector. Thus, the squadron was a useful measure of the growth of the Imperial military after the establishment of Emperor Palpatine's New Order.

Similar to lines, the Imperial Navy's Order of Battle designated four types of squadrons: light, heavy, battle, and bombard. Light squadrons patrolled areas known to be safe with two attack lines, a skirmish line and a reconnaissance line. Heavy squadrons engaged planetary systems that possessed known enemy presences, with either two heavy attack lines, an attack line and a reconnaissance line for situations where the enemy's position and composition was unknown, or with three heavy attack lines and a skirmish line for situations where the enemy was known to be defending a fixed asset. It was common to assign Victory-class Star Destroyers to the latter type of heavy squadron. Battle squadrons contained an Imperial-class Star Destroyer. In addition to the Star Destroyer, there were at least three lines, two attack lines and one pursuit line, for an average of 18 ships. The mere arrival of a battle squadron, and more importantly, an Imperial-class Star Destroyer, was often enough to put down a planetary revolt or scare off an armed space-threat. Bombard squadrons subjugated worlds in open rebellion that had developed planetary defenses including multilayered planetary shields and large planetary guns with four torpedo spheres, a skirmish line, and a pursuit line.

Systems force


A systems force combined several squadrons under the command of an admiral, referred to as a commodore while leading a systems force. These combined forces were responsible for Imperial Starfleet actions across multiple star systems. Rather than outline specific formations of system forces, the Imperial Starfleet Order of Battle lent flexibility to commodores to pool the whole of their naval resources and shape them as necessary missions required.

Force superiority pooled at least three battle squadrons and a light squadron. With a minimum of three Imperial-class Star Destroyers and nearly 90 other starships, force superiority's mission was to achieve space superiority, defined as, "the complete absence of hostile craft within the orbital space of controlled worlds, and no chronic enemy ship activity within the entire system."

Force escort protected crucial commercial shipments, economically essential space installations or facilities, and hunted down harassing pirates. With at least two heavy squadrons and two light squadrons, force escort was the most flexible of the force pools. Commodores used force escort to run a variety of missions, knowing well that their large starship count and organizational flexibility would allow for their completion. Where force superiority was given the maxim "always send enough", force escort bore the maxim "never send too much".

Force system engaged threats that force superiority could not successfully destroy. By swapping out the light squadron for a fourth battle squadron, a commodore could get enough force to ensure complete domination of a target area.

Fleet
Where all previous units were generally bound to specific system or set of systems, the Imperial Navy designated a fleet as a "sector resource", allowing it to operate on a sector-wide scale. A fleet was the smallest unit transferred between sectors. With such a large number of units, there were thousands of potential types of fleet alignments. Common fleet deployment types included superiority fleets, assault fleets, and bombard fleets. Other examples of alignments that a fleet might have taken included a deepdock fleet, support fleet, or ordinance fleet.

Superiority fleets maintained space superiority in sectors with "four or fewer world confirmed hostile to the New Order, and no more than 16 additional worlds with confirmed significant hostile elements", a superiority fleet was deployed. With six Imperial-class Star Destroyers and almost 400 other starships, a superiority fleet was presumed to be a sufficient force for relatively calm sectors.

Assault fleets transported huge numbers of Imperial Army and Navy troops to coordinate ground operations, while maintaining space superiority around the targeted systems. With two transport forces and two force escorts, an assault fleet engaged in massive planetary and system-wide ground campaigns.

Bombard fleets contained an average of 416 ships, allocated between two system bombards and two force escorts. Bombard fleets were assigned to sectors where the Empire had determined the probability of repressing the Rebellion in the sector to be less than even. System bombards were used when the Empire would rather completely destroy a world rather than see it fall into Rebel hands.

Sector group
A sector group was the sum total of Naval strength which the Empire expected to commit to a normal sector. A high admiral commanded a sector group, a title usually granted to the Moff who governed the sector. In sectors that were involved in constant and severe naval actions, the High Admiral was a separate position from the Moff. A sector group could be expected to contain at least 2,400 ships, 24 of which were Star Destroyers (Imperial-class Star Destroyers were the norm, but some groups contained older model Star Destroyers), and another 1,600 combat starships.

Starship classifications
It should be noted that considering the nomenclature of ship classification used by modern navies, many Star Wars starships appeared to be misnamed. However, it is to be expected that different cultures and societies go by internally rationalized classification-systems.

Some ambiguity surrounding the Imperial Starfleet's system has been somewhat rectified by several attempts at classification in technical manuals and novels.

From sources like the Marvel Star Wars comics, Dorling Kindersley reference books, the combat-strategy videogame Star Wars: Empire at War, Kuati-focused novels like Slave Ship etc., a system analogue to the ones used by real-life navies can be applied to the warships of the Republic/Empire (primarily the dagger-shaped design family prominently featured in stories):


 * Smaller vessels like the vaguely dagger-shaped Broadside-class cruiser were designated as "Corvettes". These were roughly similar in both size and function to non-Imperial corvettes.


 * Bigger craft like Immobilizer 418 cruisers and Acclamator-class assault ships were designated "Frigates". Extrapolating from this they could probably also have been designated "Star Frigates" to help set them apart from smaller, less-powerful ships using the "Frigate" term.


 * Victory-class Star Destroyers up to at least Imperial-class Star Destroyers were designated "Star Destroyers" and served in typical destroyer roles (while also being more flexible than conventional destroyers).


 * Imperial "Star Cruisers" were mentioned as being bigger than Star Destroyers in Inside the Worlds of Star Wars Trilogy. (These are not to be confused with the Mon Calamari Star Cruisers.) Kuati cruisers were mentioned alongside Kuati destroyers in Slave Ship. These are most likely the same types of ship as the Imperial "Star Cruisers". Note, the additional use of the term "Cruiser" to generally define warships emphasizing guns over carrier ability is talked about here.


 * Procurator and Praetor-class vessels were examples of ships designated "Star Battlecruisers", implicitly being ship-types inbetween "Star Cruisers" and larger Imperial "battleships", similar to historical battlecruisers. Since several other sources (Marvel, Slave Ship) mention Imperial "battlecruisers" and in their visual representations, show them as ships larger than Imperial-class destroyers, they are most likely the same as the "Star Battlecruisers".


 * There have been mentions of Imperial "battleships" in both old and new sources. Whether these were meant to be larger and more powerful than "Star Cruisers" and "Star Battlecruisers" is not clear, although one source (The Illustrated Star Wars Universe) specifically mentions battleships that were larger than Imperial-class Star Destroyers.


 * Lastly, at the top of this scale, would be the largest battleships, or "Star Dreadnoughts" ("Star Dreadnaughts", as written in American-English) like the Mandator-, Executor-, Sovereign-, and Eclipse-classes. They were the most heavily armed and armored ships in the Starfleet. The name is based on a real-life term, where dreadnoughts were heavily armed and armored battleships. One of the first superweapons of the Galactic Empire, Eye of Palpatine, was called a "dreadnought". It was stated as being much larger and more heavily armed than Executor-class vessels.

Imperial identification procedures
It seems that starships of the Imperial Navy do not carry any nationality prefixes at all, as most modern world navies do. Instead, a vessel hailing another craft or station establishes communications by identifying itself with the term "Imperial", followed by the ship's class designation and finally the actual name.

For example, Garrett would therefore call itself "Imperial Star Destroyer Garrett", as you can hear it in a transmission when playing the computer game Star Wars: TIE Fighter. Also, as a lot of smaller ships in the vast armada of the Empire do not even bear a real names but only registration numbers, it would sound kind of ridiculous when a vessel would identify itself with a tag (like "this is ISS 019"). Instead, in the tutorial of the computer game Star Wars: Empire at War you can see an Acclamator identifying itself as "Imperial Acclamator Oh-One-Niner". Some novels, like Republic Commando: Hard Contact, make it seem likely that this procedure has already been common in the navy of the Galactic Republic, just with the term "Republic" being used in place of "Imperial".

Note that this is but a hypothesis, as this topic has never been discussed by any official sources. Yet, a large amount of novels and computer games are using the system described above, so there seems to be some kind of continuity, or at least an established habit of the different authors.
