"I would continue this, but the Atrisian fleet has woken up. To business, then."
@[member="Cyrus Tregessar"] faced the following scenario. The Fringe forces, thus far, were in three portions, rapidly becoming two. @[member="Sargon Vynea"]'s contingent had long since escorted several Finality-class supertransports to a landing zone across the planet from Jar'Kai. The Astral Horizon, operating independently from the Fringe battle fleet, had achieved geostationary orbit and begun to disgorge its landing craft. The main body of the Fringe fleet, however, several Permanence-class battleships with escorts, was streaming along to join the Horizon and face Tregessar. The Atrisians had stopped at the edge of turbolaser range on the descending dropships, and the Chrysalide-class battlecruiser returned fire with over eighteen hundred turbolasers.
That wasn't the main event; nobody here expected it to be. A standard Fringe fleet relied on Permanence-class battleships, which had been designed not for straight-on fire like a Star Destroyer, but for broadsides -- and not for a line of battle, but for a wall, moving oblique to the angle of Tregessar's fire. Permanence-class vessels formed the critical points of the wall, the intersections of an unseen grid. Wasp and Wasp-B heavy cruisers, Adara-class corvettes, and Deathhead heavy cruisers filled in the gaps. The fighter screen was standard enough, though Malos-clas gunships refrained from joining in. Instead, they and a portion of the fighters escorted a portion of the battleships' Hammer-class dropships to join the descending ground forces of the Astral Horizon. Meanwhile, the quick little Adara-class corvettes moved ahead of the wall to interpose themselves between the Atrisian forces and the landing craft. The corvettes wouldn't be able to take much in the way of punishment, but at this point, every little bit helped.
Still, the Gyon heavy cruisers and Star Destroyers took a good chunk out of the landing force, at the undoubtedly-foreseen cost of letting the Fringe capital ships take unreciprocated swings at them. Close to forty percent landing craft losses trickled back to the bridge of the Astral Horizon, putting a serious dent in the Permanence battleships' contingent. The Permanence was the backbone of the Fringe, and their ground assault capacity would have helped rather a lot. But that couldn't be fixed at this point.
The ground forces which reached the plains beachhead, under cover of the brave corvettes and a truly ludicrous amount of turbolaser fire, might, just might, be enough. Not all of the battleships had sent down their landing craft; those would be held in reserve. All in all, each carried enough dropships to put down the full twelve hundred troops plus basic transport repulsorcraft. A Permanence's contingent was not designed to be self-sufficient.
The forces which @[member="Moira Skaldi"]'s detachment faced, after the forces of four Permanence-class vessels were added in -- and after the thirty percent losses suffered at the hands of the Atrisian fleet -- totalled the following, setting up on the plain outside Jar'Kai and the pass to the Palace.
7,400 troops with 230 repulsor vehicles
42 Malos-class gunships
20 Dreadhawk-class gunships
4 Detryte-class bombers
4 SMP Medical/Command walkers
35 SAP support walkers
17 Akure-class parabolic artillery tanks
The gunships ignored the forces which @[member="Moira Skaldi"] had deployed. Instead, they went straight for the pass, under cover of three interceptor squadrons at high altitude. The Malos was built for durability -- Force bless Koensayr! -- and the Dreadhawk was exceptionally maneuverable in atmosphere. More to the point, the Malos carried dozens of thermal detonators in addition to its normal warhead load, and the Dreadhawk, small as it was, carried two full-scale seismic charges.
There was no question, of course, but that @[member="Akio Kahoshi"]'s defenses had turned the pass and, especially, the Palace into a zone of air denial. The cost was judged acceptable to those whose plan involved dropping some proportion of forty seismic charges, a hundred and sixty-eight full-size flame carpet warheads, and just under twenty-seven hundred thermal detonators on that mountain pass, right through the teeth of the heaviest anti-air defenses in a hundred parsecs. Tregessar wasn't the only one who could prioritize. The gunships would have been exceptionally helpful in space, but the fleet would just have to make do without them.
Meanwhile, the ground forces were forming up to confront the battle group which Skaldi had sent. Numerically, Skaldi had the edge in tanks, and arguably in walkers as well - the SAP was a fast little blighter, but nothing like as heavy as the AT-ST, and the SMP was a mobile command and medical station, not a front-line AT-AT equivalent. The Fringe might have the edge in manpower, but that only counted for so much when walkers and tanks were in the field.
If an equalizer existed, it was the Akure-class -- blocky, tracked, and capable of merely light walker speeds. No match for Atrisian tanks up close, of course. The Akure-class, however, was capable of lobbing a seismic charge nearly twenty kilometres, making it a medium-range, high-damage parabolic artillery piece. The twin quadruple launchers could be fire-linked or independently targeted, barrel-by-barrel. Each seismic charge was fired inside a disposable, thruster-equipped, single-use inertial dampener to prevent premature detonation. The shots were purely parabolic, not guided in any way. The thrusters were solely for increased range.
The Akure-class presented a major danger of friendly fire and needed be deployed very carefully, by experienced commanders. A misfire could wipe out entire friendly units.
It was named after the biggest, nastiest terentatek ever. Just because.
They would get one barrage, presumably, before those blindingly fast repulsortanks got close enough to exchange fire with the perimeter of SAPs.
A hundred and thirty-six seismic charges, range twenty klicks, arced towards the assembled Atrisian forces. They'd been brought to crumble the mountain pass, but they'd been designed for grasscutter level-plane detonations. Plains were pretty much ideal for the Akure.
