Looks all right, although I kind of like the Bastion better than the AirGuard. Fewer things that can go wrong, you know?
Looking at them again, I think I agree. I swapped Bastion out because it was the part Sir_Travelsalot suggested be swapped out, keeping it would probably work better...
Also, Narwhal doesn't have an E.
Blame whoever did that write up, it wasn't me.
Also on the subject of more add ons and or utility parts for Exo-Armor and Naval Marines...
(Utility) Armsmen Garrison Deck
By dedicating an utility component's worth of space to housing Naval Armsmen and associated gear, as well as the needed equipment to maintain and repair frame armor such as Shelters, it is possible to maintain a substantial amount of them on board in both the deck itself and across the ship to supplement already existing security stations. This vastly increases both the quantity of trained manpower for shipboard combat operations and the amount of Shelter type Frame Armor available given the continual maintenance and repair issues such assets face. With this increased manpower, a ship so equipped can expect consistently superior results for onboard combat, both defensively or, if paired with an appropriate delivery system, offensively.
Hmm. Alternate plan suggestion.
Potential Plan Shields, Boarding Combat, and a Warp Drive.
(Defence) Haptrix-Alpha Interlock Shields: The Haptrix-pattern shields are a serviceable design, but are fairly expensive, and have proven somewhat unreliable in practice. Perhaps worse, they are projected to scale up poorly both in terms of cost and in ability to stop capital-scale weaponry. This redesigned version uses a smaller number of larger shields to simplify the design and strengthen each pane, and arranges them in two concentric shells with the panes offset like bricks to provide redundant coverage.
(Boarding Craft) Narwhale Breacher Craft: The first dedicated boarding craft developed in the Crusade, the Narwhale outwardly bears a great deal of resemblance to the Harbinger Transport, because it uses the same hull configuration. Internal space has been sacrificed to add additional reinforcement to the superstructure, more powerful engines, and even install a small Void Shield. An array of hull cutters is affixed to the prow to force entry onto an enemy vessel and deliver its cargo of boarding parties.
(Utility) Naval Armsmen Garrison
By dedicating an utility component's worth of space to housing Naval Armsmen and associated gear, as well as the needed equipment to maintain and repair frame armor such as Shelters, it is possible to maintain a substantial amount of them on board in both the deck itself and across the ship to supplement already existing security stations. This vastly increases both the quantity of trained manpower for shipboard combat operations and the amount of Shelter type Frame Armor available given the continual maintenance and repair issues such assets face. With this increased manpower, a ship so equipped can expect consistently superior results for onboard combat, both defensively or, if paired with an appropriate delivery system, offensively.
(Warp drive) 'Longstride' Warp engine. While the typical drive utilized in merchant shipping suffices, the minimal use of technology and advanced components to save costs caused them to have slow charge times, greatly limited speed through the Warp and not being suited for fast/emergency jumps. The Longstride was Calavar's first attempt at improving their engines to something closer to what is utilized on Imperial Navy ships.
My main worry would be that people will push to make boarding combat ships instead of the staple combat ships and transport ships we really need, as well as the hulls we'll need to bribe/influence/get in good with Yttreum, but even with that risk it'd be good to get that stuff done.
And of course the Naval Armsmen Garrison could be replaced by the Combat Servitor Bay if people would prefer that. Long term I think the best boarding ships would probably be a Resolute hull, using the two utility slots they have to hold both an Armsmen Deck and a Servitor Bay for both ample infantry, a good number of power armor knockoffs, and all the Murder-Servitors we might want to lead the charge into an ork or daemon infested ship, but even with that option we probably should only do one of those two designs this turn at most.
Also oh hey, a sidestory!
Edit : Hmm. Still might be dark Mechanicus, still might not be. Whomever it is has the good toys available, but that's not true evidence either way given that Explorators can be very good and are on the mission to find good stuff anyway. And Vortex Torpedoes, which is what those looked to be, are a known thing. Shielding the torpedoes though... probably not normally done because of expensive, but if you really want some to hit...
I kinda wanted to wonder if Ulshavon might be Necron influenced, but I doubt they'd use vortex bombs.
