Home One, also known as Headquarters Frigate, was a modified MC80A Home One Type Heavy Star Cruiser of the Alliance Fleet, famous for its role as Admiral Gial Ackbar's flagship during the decisive battle fought at Endor.
Home One was originally constructed as a civilian deep space explorer but was later retrofitted for military service. It featured heavy hull plating and triple-strength shields, along with twenty hangars for bearing other warships and starfighter squadrons. It was 1,300 meters long, slightly larger than the standard length of an MC80 Star Cruiser. It was initially armed with turbolaser cannons, ion cannons, and several tractor beam projectors. It was the largest and most advanced ship in the Alliance Fleet. The ship's briefing room was originally a holographic amphitheater. At least two sections of the ship could detach themselves from the main body, and become fully-independent attack or escape craft should the need arise. The ship's command crew was entirely made up of Mon Calamari. This makeup was due to the fact that the controls were specifically designed for that species. Originally, the ship was built with water-filled passages for the Mon Calamari crew to swim through, but these were later cleared out for other species.
In 2 BBY, Home One was present during the first official gathering of the Rebel Alliance above the planet Dantooine.
Home One served as a mobile command center after the Empire discovered and destroyed the main Alliance headquarters on Hoth. It was also the command ship where Mon Mothma, Crix Madine, Admiral Gial Ackbar, and a host of other important Alliance officials briefed members of the Rebellion on the upcoming battle on and over Endor. After Mon Mothma pointed out the strike force's primary objectives and following the departure of General Han Solo's land-based Pathfinder commandos, the ship jumped into hyperspace and arrived in the Endor system after utilizing the secret hyperspace route known as the Sanctuary Pipeline, and immediately entered fierce space-combat during the Battle of Endor. It served as the lead ship and the command and control center for the attacking Rebel fleet against the second Death Star, and was the flagship of Admiral Ackbar, earning it the moniker "Headquarters Frigate."
In the months following Endor, the ship would still be undergoing final repairs from the climactic battle, while newly appointed Fleet Admiral Ackbar would designate the ship as his command vessel, and practice hand-to-hand combat in its holographic chamber to keep his reflexes sharp. In addition, he would order the deployment of members of New Republic SpecForces in a sub-orbital drop onto the planet Akiva after receiving momentary contact with downed pilot Wedge Antilles and a brief meeting with New Republic leadership. The members of the operation, unbeknownst to Ackbar, would play an important part in disrupting the Imperial Future Council.
Later, Admiral Ackbar used Home One as his command ship during the successful New Republic campaign to capture the planet Kuat and the important Kuat Drive Yards. Ackbar later corresponded with Princess Leia Organa, Commodore Kyrsta Agate, and Chancellor Mon Mothma as they received a peace offer from Grand Admiral Rae Sloane. Home One later took part in a brief space battle with Imperial Star Destroyers above Kashyyyk. The cruiser also accepted the surrender of the Star Destroyer Neutralizer.
Home One would go on to participate in the Battle of Jakku, still under the command of Admiral Ackbar. During the battle, Home One served as the New Republic fleet's command ship. From Home One, Admiral Ackbar coordinated the battle with other New Republic commanders including Commodore Kyrsta Agate, General Tyben, and Lieutenant General Brockway. Home One along with Agate's Starhawk-class battleship Concord took part in the assault on the Imperial Star Destroyers enveloping the Imperial Super Star Destroyer Ravager, which served as the Imperial command ship. From the bridge of Home One, Ackbar watched as the Concord used its powerful tractor beam projector to drag the Ravager to Jakku's surface. This turned the tide of the battle decisively in the New Republic's favor, leading to the Empire's capitulation and the Galactic Concordance, which ended the Galactic Civil War.
Following the war's conclusion, Home One continued to serve the New Republic, accompanied by an escort of X-wings. Around 9 ABY, former Jedi Knight Ahsoka Tano met up with New Republic general Hera Syndulla to discuss the missing prisoner Morgan Elsbeth on the cruiser. Mon Calamari, too, were still serving on the ship, with one such officer asking Syndulla for an update on the situation on behalf of the Senate Defense Council. Sometime later, Home One was accompanied by a massive fleet of EF76 Nebulon-B escort frigates, CR90 corvettes, Sphyrna-class Hammerhead corvettes, and New Republic cruisers, and a squadron of A-Wings. General Syndulla called a meeting with Chancellor Mon Mothma and members of the New Republic Senate, including Senator Hamato Xiono, to discuss the threat of Grand Admiral Thrawn's return and sent New Republic forces on Seatos to stop it. Despite Chancellor Mothma's support, the other senators refused to believe that Thrawn is still alive and denied Syndulla's request.
Home One later belonged to the Resistance under General Leia Organa. Commander Poe Dameron was assigned his first big mission on Home One.
Home One first appeared as the Rebel Alliance's command ship in Star Wars Episode VI Return of the Jedi.
