Battlefleet Azuran

Battlefleet Azuran is a relatively young (founded first in mid-M38) Imperial Navy fleet consisting of 59 active ships and 7 ships currently in-production. It is tasked with the protection and patrolling of the Azuran Sector, protecting commerce, transportation of colony ships, lending assistance to sactioned Rogue Traders, and, at times, accompanying the various Imperial military forces which maintain strong presences in various worlds within the sector. It has so far met with few losses and several great victories, particularly in suppressing the recent Night of a Thousand Rebellions and the Macharian Heresy alongside their home sector's patron Adeptus Astartes chapter.

History
Battlefleet Azuran was founded once Imperial rule was brought along with the Ordinators and the Ark Mechanicus that would become the beginning of Forgeworld Ferunus shortly after. Though initially, the sector was protected by a small number of Imperial Navy cruisers and escorts temporarily drawn from nearby Segmentum Pacificus sectors, as the Ordinators  managed to import newly christened Strike Cruisers and a Battle Barge, and Forgeworld Ferunus' ability to produce both Imperial Navy and Astartes-pattern ships, the sector's naval strength began to become produced and maintained from within. As the Ordinators grew into a full chapter of their own - often departing with much or most of their fleet for mysterious missions around the entire Imperium - the drydock manufactorums of Ferunus began to dedicate themselve to creating large numbers of Imperial Navy-pattern warships (though the Lord Admiral's flagship, a Nemesis-class Battlecarrier, christened Shield of the Golden Throne, was imported from elsewhere in the Imperium by Forgeworld Ferunus in some manner of trade). As Ferunus accumulated more and more STCs, it became fully capable of producing the current Battlefleet to protect their home sector in addition to their own naval forces - more often away from home seeking various tech or STCs than not - fully aware they needed a powerful, dedicated naval defensive force to protect themselves and the worlds they had taken as allies and de facto vassals. After a series of constant wars in Segmentum Pacificus around the nearby Gerrhae and Macharia sectors in late M41, it was only by the end of the first half-century of M42 that Forgeworld Ferunus managed to repair and restock the fleet with its appropriate number of void and atmospheric craft, as well as refitting them with several rare defensive technologies.

Combat Doctrine
The Imperial Naval forces of Azuran are smaller than many other Imperial Navy Battlefleet formations in more populated or defensively-critical sectors. It is reluctant to split into more than four primary defensive patrol/strike force Battlegroups at any given time, and whenever Lord Admiral CYZYFA is given the opportunity to, he will pursue a major threat with typically most of his sector's battleships foward along the flanks - with the exception of his ASFDASD-class Battlecarrier, which charges directly into the center - as the vanguard of a four-pronged, three-dimensional pincer attack where he rushes into broadside range as his lance craft and Cruisers fire and fly into the center. As the Battlecarrier and its cruiser escorts absorb the initial volleys of the enemies, his flanking battleships unleash massively powerful broadside macrocannon attacks  that make them impossible to ignore. As this occurs, the fleet frigates and destroyers circle the field, trying to find weakened ships or other targets of opportunity to strike at with lance and torpedo fire, using their cannons as defense against enemy escorts. This Lord Admiral ASDAUSID's defining tactic and has resulted in tens of victories in the course of his short career as the youngest officer to ever hold the post in the sector. Commissars are regulated retained aboard the Bridge of each ship in the fleet to ensure his iron sense of discipline is retained by all his subordinate Captains and Commanders.

Surrounded y such a cloud of overwhelming firepower and hundreds-strong clouds of Fury Interceptors and Starhawk Bombers, most enemies of the Imperium are forced to attempt a retreat before long, though the Admiralty of Azuran do not believe in letting a battle end in anything but a total massacre of the enemy. Ships attempting to make emergency warp jumps will tyically be rammed from both sides to prevent their escape by the colossally armored prows of heavy cruisers or even battleships. If an enemy chooses to engage in boarding combat, the fleet's relatively few Shark Assault Boats are rarely used except in particular scenarios where something or someone of value is needed retrieved in the heat of battle by a specialist shock assault corps of multiple Naval Tempestus Scions Regiments, formally known as the "Naval Special Warfare Operations & Recovery Detachments", or, "the NAV-SWORD", by the line ratings of the Azuran Battlefleet. Though highly trained in boarding operation, these carapace-armored, hellgun, melta, and plasma weapon-armed Stormtroopers are primary retained to act as counter-boarding quick reaction forces, while the rank-and-file Armsmen are trained to both fight with boarding shotgun and lasguns as well as man fortified twin-linked plasma gun turrets found at junctions retrofitted to most ships in the Battlefleet.

The pilots of the fleet are trained almost entirely on how to make devastating bombing runs on enemy ships - training particularly to fight the craft of forces of Chaos, Eldar Corsairs, Dark Eldar Raiders, Ork Freebootaz, and occasionally Necron warships (though these are rarely found in the area of operations in Azuran). Civil conflict has been increasing common since the final year of M41, and Battlefleet Azuran in M42 has adapted to utilize tactics that focus on utilizing bombers and lance/torpedo salvos to disable the engines of secessionist or renegade Imperial-manufactured warships before raking it with broadside fire onto the exposed and less-armed dorsal side of their targets. Special squadrons of the fleet consisting primarily of Marauder Bombers and Thunderbolt Fighters (with a somewhat lesser number of Valkyrie Assault Transports and Lightning fighters, respectively) do frequently find themselves fighting alongside the Imperial Guard (particularly the Arothi Ferric Guard), though they have accompanied the Ordinators on several large crusade-level missions such as in the Suppression of the Macharian Heresy.

Despite this aggressive tactical doctrine practiced by both the current and the past two millenia of leading Lord Admirals of Battlefleet Azuran, the Ordinators and Forgeworld Ferunus - the de facto co-rulers of the sector - insist that at least a third of the Battlefleet remains within its home sector at all times, and it has become an unspoken rule that the Battlegroups that are allowed to conduct warfare or logistical/transport operations out of the Azuran Sector must return within under four years. The Ordinators have been known to chase down overambitious Captains or Commanders who have been out of the home sector for too long attempting to earn glory only to forcibly return them home in order to ensure the Battlefleet remains a primarily defensive force, despite the relatively small number of worlds in the inhabited sub-sectors of their home.
