The Imperial Inspectorate HQ, also known as the Imperial Inspectorate Command Center, was the headquarters of the Inspectorate. Located on the Core World Coruscant, it was originally a Republic Military facility, known as the Republic Center for Military Operations or the Republic military base, during the final years of the Galactic Republic. The architect who designed the base was Lieutenant Commander Orson Callan Krennic. It later became the Naval Intelligence Headquarters as the headquarters of Imperial Military's Naval Intelligence Agency.
During the Clone Wars, former Jedi Commander Ahsoka Tano was trained by clones and was also put on trial for treason at the Republic Center for Military Operations. The charges against Tano were dropped after another Jedi, Commander Barriss Offee, was revealed as the true culprit behind the terrorist bombing of the Jedi Temple.
With the rise of the Galactic Empire, the Republic Center for Military Operations was re-designated as the Imperial Inspectorate HQ. It formed the so-called "supreme triangle" in Imperial City's Federal District, together with the Imperial Palace and the COMPNOR arcology.
The Imperial Inspectorate HQ was a shielded, hardened, near-windowless complex located on the capital planet Coruscant's Federal District, alongside the COMPNOR arcology and the Imperial Palace itself. The complex was located adjacent to the Coruscant shipyards where Venator-class Star Destroyers docked.
The Inspectorate possessed scanner, sensor, and communications arrays on its roof during the Imperial Era and was defended by two turbolaser batteries. It also had micro-holocams and recorders built in every corner of the complex so that the actions and conversations of every worker could be monitored. Several enclosed hangars and landing bays were scattered in the grounds around the facility and hosted multiple transports and starfighters. The base was also home to the military prison which hosted high-profile Separatists too valuable to send to a criminal incarceration facility, including Emir Wat Tambor, Archduke Poggle the Lesser and General Whorm Loathsom. The prison also hosted former Jedi Barriss Offee, convicted of treason after the bombing of the Jedi Temple Hangar.
The Strategic Planning Amphitheater was located at the summit of the facility. The First Battle Memorial was built in the center of the base's plaza, its purpose to honor the clone troopers that were killed in the First Battle of Geonosis. This commemorative monument was constructed on an enormous slab of reddish-brown rock, taken from the planet Geonosis and made into a wall engraved with the designations of the fallen clones.
During the final years of the Galactic Republic, the Republic Center for Military Operations was the base of operations and strategic center of the Republic Military. Designed by the architect Lieutenant Commander Orson Callan Krennic, it was built in the Federal District of Galactic City on the Core World Coruscant—the galactic capital of the Republic—at the time of the Clone Wars. As the Republic waged war against the Confederacy of Independent Systems across the galaxy, the facility served as the operation hub of the Grand Army of the Republic.
A committee of Republic officials, known as the Strategic Advisory Cell, convened in the Republic Center's Strategic Planning Amphitheater to discuss plans for the creation of a Republic superweapon in the first year of the Clone Wars. At one point during the war, Jedi Knight Anakin Skywalker recruited Clone Captain Rex and his men to help his Padawan, Ahsoka Tano, practice her lightsaber abilities at the base's hangar. The clones stood in a circle around Tano and fired on her with stun blasts as she practiced deflecting them. Skywalker pushed his apprentice to keep trying even as she was knocked unconscious several times. As the conflict dragged on, one of the Jedi Temple's starship hangars was bombed by terrorists, resulting in the deaths of several Jedi, clone troopers, and maintenance workers. A local, Letta Turmond, was arrested by Jedi General Anakin Skywalker and imprisoned at the Republic military base due to her involvement in the attack against the Jedi Order.
Turmond was subsequently killed by way of the Force while under interrogation by Skywalker's apprentice, Jedi Commander Ahsoka Tano. Accused of murder, Tano escaped from the base and fled into hiding in the lower levels of Coruscant. Pursued by the clone shock troopers of the Coruscant Guard, Tano was eventually captured and taken back to the Republic Center for Military Operations where she faced a military tribunal presided over by Supreme Chancellor Sheev Palpatine. Before sentencing could be carried out, however, Skywalker arrested Jedi Commander Barriss Offee after discovering that she was responsible for the bombing at the Temple as well as the framing of Tano. He took the fallen Jedi to the base's courtroom where Offee confessed to her crimes against both the Republic and the Order. As a result, the tribunal acquitted Tano on all charges, although she declined to rejoin either the Jedi or the Grand Army.
When the war ended in 19 BBY, the Republic was replaced by the Galactic Empire. As a result, the headquarters of the Imperial Inspectorate, as well as the Naval Intelligence Agency, was constructed over the monads of the former Republic military base. Together with the Imperial Palace and the COMPNOR arcology, the Imperial Inspectorate HQ was part of the "supreme triangle" in the Federal District.
A short time into the Imperial regime, the clone Crosshair was assigned by Admiral Edmon Rampart to a team of troopers that would be undertaking a infiltration mission to the planet Desix. After meeting the admiral in his office within Inspectorate HQ, Crosshair was instructed to meet with the unit's commander, Cody, outside of the building near the First Battle Memorial.
When the clone troopers were officially phased out of the Imperial Army and replaced by the human recruits of Project War-Mantle, the clones were processed at the Inspectorate HQ before being sent into retirement.
In 14 BBY, the headquarters served as the meeting place of Emperor Palpatine, his Joint Chiefs of the Imperial Military, and leaders of the Commission for the Preservation of the New Order, when a group of rebels hijacked Moff Wilhuff Tarkin's personal corvette and used it to go on a rampage throughout the Empire. At one point during the Galactic Civil War, agents of the Alliance to Restore the Republic infiltrated the complex.
Around 1 ABY, Lieutenant-Inspector Magna Tolvan went to the facility following her promotion to the agency, where she researched her deceased mentor, Thanoth, with an RA-7 protocol droid. Around 3 ABY, when the Alliance made an attack run at Coruscant, an Imperial lieutenant informed the commander of the Inspectorate headquarters of the impending attack. The commander ordered for the orbital platforms to be activated and called for half of the planetary-defense fighter wings to be scrambled. Following the rebels succeeding their attack, the commander and the lieutenant left Inspectorate HQ to see the damage caused to a statue of the Emperor.
