Designed to specifications set down by the Imperial Kyatashiro Navy in January of 106PA, the Battlemaster was originally intended to escort freighters to and from Kyatashiro. Among it's hallmarks would be heavy guns capable of inflicting grievous damage onto equally sized vessels in a short span of time, and to utterly decimate smaller watercraft with single shells. The designers at the Imperial Kyatashiro Shipyards were not fools however, and so chose to create the Battlemaster as a dual action cruiser, as both a cannon armed vessel, and a missile cruiser at once. It would incorporate two turrets of three 155 mm cannons, one at the fore and one at the aft of the vessel's superstructure, and four smaller turrets, each with two 127 mm cannons, framing the larger turret installations. The missile armament would then be composed of two different types of systems. Two medium range missile turrets would be mounted above and behind each of the main turret installations, and a large cruise missile battery would be built into a raised portion of the central superstructure. This combination of weaponry was hoped to be more than adequate to equip these vessels for their intended mission. Hachiman authorized production of the Battlemaster class after quickly looking over the designs, and information - and announced that he would want SIX Battlemasters for the Imperial Kyatashiro Navy! These would be produced in two batches of four and two respectively, according to his plans. Thus construction of the first four Battlemasters began in September of 106PA.
While the hulls of the four sister vessels were still under construction, talks were under way between Kyatashiro, Desert Star, Lazlo, and the newly formed nation of Wa-Daisho about the formation of a new 'united fleet' that would come to be known as the Joint Naval Force, and later the Allied Naval Fleet. During these discussions it was made abundantly clear that this new naval force would require heavy cooperation from Kyatashiro to exist. Hachiman saw this as a very exciting prospect. Since his forces would play such a crucial role in it's formation, he would have a very direct hand in the control of this powerful, multinational force - thus it was decided that the first of his Battlemasters would also be relegated to this force.
The first of the Battlemasters was finished and commissioned in the Joint Naval Force in November of 108PA, as the J.N.F. 5 Tiger. Over the course of the next three months, the other three Battlemasters would be commissioned as well - two to the Imperial Kyatashiro Navy, and one more to the Joint Naval Force. Shortly after this period Hachiman decided not to over tax his naval personnel by providing too many vessels, and so canceled the other two planned Battlemasters - the tooling, and built components being carried to Wa-Daisho for use in future construction programs.
Service began for the type almost immediately after the first vessels were commissioned. To that date lightly armed freighters had been running freight from point A to point B using only their own guns, and occasionally the light patrol vessels then in service in the Imperial Kyatashiro Navy! The appreciation of the type was nearly immediate as well. Literally dozens of pirate attacks were warded away from the freight convoys, and still dozens more monster attacks were ended abruptly at the guns of the four Battlemasters.
As escort vessels the Battlemasters of the Joint Naval Force saw a great deal of service fighting against smaller vessels, and other threats but took until late in 110PA before any vessels of this type would see any significant action. During this time frame, a pair of Splugorth Sea Skimmers entered Kyatashiro's mist shroud surrounding the island, and so a core of seven vessels went to meet them. Among these vessels was the J.N.F. 5 Tiger, operating as the core vessel to a quartet of Whiteshark class patrol boats. While the J.N.F. 9 Stingray engaged the first of the Sea Skimmers, the Tiger and the Whitesharks proceeded to engage the other Sea Skimmer utilizing their speed advantage, great weapon ranges, precision accuracy to disable the Sea Skimmers weapon systems, and destroy their means of propulsion. During the course of the melee the Tiger took two heavy torpedo hits from the Sea Skimmer in question, and a few light hits made by flying enemies deployed by the Sea Skimmer. Although technically a lighter vessel than the Splugorth vessel, by a great deal - the Battlemaster proved itself to be deadly in full scale sea battles.
Meanwhile of these events, the Battlemasters of the Imperial Kyatashiro Navy were making their own share of operations. Many operations conducted by the I.K.N. were simply defensive in nature, but there were several cruises in which one or the other Battlemaster of their fleet would be sent out to engage foreign freighters in cooperation with a fleet or vessel of unknown origins they simply knew as the Shogun. These operations were very similar in nature to privateer work. Oftentimes, the I.K.N. Battlemasters would jam radio signals from the foreign vessels, and would demand them to allow a boarding party. IF there was resistance, then the vessel would be sunk. If they would allow boarding, they would look over the supplies, and IF the supplies were deemed as valuable to Kyatashiro, freighters kept in reserve - likely in hiding, would be called forward to take stock and capture the cargo. There have been times in which the vessel itself was taken as well, however rare. These vessels primarily operated on the high seas of the Atlantic, but also operated along the shores of Quebec, and especially around England from mid 110PA to 114PA. Later, these vessels would also see service in similar operations against both Coalition and Free Quebec shipping!
The J.N.F. 6 Thresher, the last Battlemaster built in Kyatashiro, made a showing in Wa-Daisho territorial waters on September 5th, 115PA when the Thresher accompanied a number of J.N.F. vessels and Wa-Daisho Naval Ships, in the event that first brought the Allies to meet the New Navy, under relatively peaceful terms.
A few months after the name change of the J.N.F. to the Allied Naval Fleet, the Battlemasters of this renamed unit were again put into action, for the first time in the offensive role! The Allied Naval Fleet was called into action to defend a secret alliance with Free Quebec, in September of 116PA. Situations had warranted the Free Quebec navy to be in supreme danger, and so the Allied Naval Fleet from two fleet posts, one in the Pacific near Wa-Daisho, and one near Kyatashiro, made their way to the mouth of the St. Lawrence via use of an alien technology portal creating device. Once there, the Allied Naval Fleet literally made a surprise attack on the majority of the CS blue water navy! The combat was long and brutal. During this time, the Thresher and Tiger acted as flag ships to the small vessel screen around the two fleets. During these actions, both vessels sunk a number of small CS vessels such as Wave Demons, Barracuda, and even a couple of Hurricanes. The Thresher saw a bit more action than the Tiger, when the Sabre and Samuel de Champlain rushed the screen of the Dalmir's carrier group. During the ensuing combat, the Thresher took a great deal of damage, and although both vessels were sunk by the Thresher, and the screening pattern held, the damage inflicted was grievous. A volley of proton torpedoes had made it through the defensive rail gun sprays, and the explosion resulted in a hole 60' in diameter at the waterline of the Thresher. Although she did not sink, flood control could not keep the water rushing in under control. Shortly after porting with the Dalmir to a port in Kyatashiro with the Dalmir carrier group, she capsized. It took over six months to get her back up to spec and fully operational again.
In March of 117PA a new Battlemaster was commissioned into the Allied Naval Fleet by Wa-Daisho's Shipyards, using components and tooling formerly used almost ten years before in Kyatashiro to build the previous two vessels. A scarce two months later a second new Battlemaster also joined the fraternity of Battlemasters, and to date have not yet seen any major action.
Currently, there are six Battlemasters that have been built. Two are in service with the Imperial Kyatashiro Navy. The I.K.N. 20 Surikami, and I.K.N. 21 Metsukami. As of February 2nd, 118PA these two vessels are patrolling Kyatashiro's waters, roving for any trespassing vessels. It is planned that come spring, they would join the Shogun again in privateer operations against the Coalition and Free Quebec navies. The Allied Naval Fleet now has four Battlemasters, the J.N.F. 5 Tiger, J.N.F. 6 Thresher, A.N.F. 23 Hammerhead, and A.N.F. 25 Mako. The Tiger and Thresher both operate out of Kyatashiro. The Tiger is currently with the Yellow Submarine and the Stingray investigating rumors of a Splugorth Mothership in the region of Republican. The Thresher is currently operating with the Kyoto Class Escort carriers, escorting freighters to friendly ports. The Hammerhead and Mako are both in port in Wa-Daisho as of February 2nd, 118PA refitting after a cruise to Japanese waters with the Dalmir and Manta.
