(Macrocannon Add-on) Seekershard Shells: Though thus far the foes encountered by the Crusade have been largely a non-issue with regards to repelling strikecraft, the Admiralty has expressed interest in countermeasures that would be ready for rapid deployment among existing fleet elements. As the amounts of required space for allocation of proper point defense arrays is at a premium in the Hegemon's warships, an alternative has been proposed in the form of a unique form of macrocannon munitions. The Seekershard Shell consists of a fairing that ensconces the shell's payload, in effect a communications receiver pylon, which will feed targeting telemetry from the ship's sensorium to the dozen anti-fighter rocket pods mounted on it. Upon receiving their target locks, the missiles, alone far too weak in propulsion to achieve meaningful range, will fire towards the enemy craft. While the system is reliant on the ship in question spotting the enemy strikecraft prior to engagement and the missiles themselves are projected to rely more upon area denial than advanced targeting to achieve their objective, there are high hopes for the project.
(Utility) Vault-pattern Magazine: As the Thermo-Cavitation shells have proven to be of great use in improving the firepower of Calavan warships, the admiralty is keen to continue additional research into special munitions. However, the concerns of having to dedicate entire gun batteries to storing specialized shells being a limit to their tactical versatility have necessitated designing a workaround to the usual practice of each cannon having its own munition stocks. The Vault-pattern Magazine takes the form of a cargo bay, modified with additional armored bulkheads and reinforced to mitigate the tremors of impacts on the hull. A network of overhead crane lines kept isolated in non-grav plated sections convey the shells to the gun crews in preparation for a volley.
(Weapon) Standard Macrocannon Battery Mk2: A natural iterative development of earlier Calavan macrocannons, the Mk2 utilizes many of the same components as the Mk1 to ease logistics concerns regarding spare parts. The key difference is two-fold; the electromagnetic coils in the gun's barrel have been wound twice as tightly to provide a significant increase to projectile velocity, and the batteries themselves have been installed with shock dampeners not unlike those in structures built on seismically active regions, so as to mitigate an incoming impact's effects on accuracy.
(Light Cruiser Hull) Martinet-class Hull: The first Calavan foray into the design of Light Cruisers, the Martinet takes much of its design elements from the purified bulk hauler captured in the initial reclamation of Bailafax. But where the heretics had simply battered the civilian hull into serviceable form, the Martinet has been streamlined and built from a foundation for warships.

(Defense) Corona-pattern PD Array: While our strike craft have thus far proven adequate defense against the enemy's, it has been considered prudent by the Admiralty to have additional countermeasures on ships that the Crusade could scarcely afford to have struck by torpedoes. The cogitator framework that directs the fire of the Lascannon turrets has been adapted from conventional flak arrays and spliced into the ship Sensorium's datafeeds for enhanced target acquisition and tracking.
Here's my list for what I plan to vote for during this design phase. RNG willing, we'll have everything we need to bring our fleet to modern spec for the most part with these.
