These are take-aways for my own reference. They make sense: grav tanks and other sorts of helicopter/gunboat-like things should have armor and weaponry and sensors appropriate to their mission. And I assume comms are cheap and light, therefore I can't see why a reasonably typical grav tank wouldn't carry an orbital comm.

Default Redesigned Trepida

I've finally posted a redesigned version of the Trepida in the file library (here).

I shrunk it a bit, making the combined volume of the hull and turret total 10 Td, making it compatable with the Astrin for use in the RDA described in 101 Vehicles.

Improvements address many of the problems I mentioned farther up in this thread. It is faster and has a better communications suite. Sensors are not great but are much improved over the original. It also carries a VRFGG as secondary armament.

Some weaknesses remain, such as the 40G armor rating. It also lacks a point defense weapon system.

However, there are a number of other improvements that were byproducts of some of my design decisions. I increased crew size from two to three which allowed me to reduce the computer from a model 3 to a model 1. That plus a couple of other minor tweaks reduced the overall system cost considerably.

Next will be a similar rework for the Astrin and the Empress designs from 101 Vehicles. Please let me know if I've missed any errors in the Trepida so I don't make the same mistake with the others.

Default Astrin design shortcomings

I didn't realize before taking a close look at both designs side-by-side, but the Astrin design is almost a complete copy of the Trepida... except the Astrin has no weaponry at all.

Even the hull volume is the same, though it shouldn't because the Astrin has no turret. The UCP lists a 10 Td hull but hull damage points are the same as the Trepida which, following Border Reiver's comments above, has a 10 Td hull plus 30% for the turret.

So, the Astrin shares the same weaknesses in communications as the Astrin and has no weaponry at all (making the sensor suite superfluous). The hull damage points are too high for the stated hull volume. Max acceleration is lower than what it should be. And the power plant seems needlessly large since there is no weapon system drawing power.

Given the description of the RDA, a system designed to deliver a mix of Trepida and Astrin vehicles, that the two systems should be designed to complement one another. But this design is only able to deliver infantry to the fight, not to be a participant in the fight.

I can see a vehicle whose purpose is primarily to deliver infantry, but I can't think of any vehicle designed since before WWII purely as an armored personnel carrier that didn't at least mount a suppressive or air defense weapon.

And it would make much better sense to me to have a carrier vehicle that can support other vehicles in the formation during movement and that can support the dismounted infantry while they close. The first role might best be accomplished with a laser coupled to a point defense targeting module and the latter might better be served with a high ROF suppressive weapon or auto GL.

It will be awhile before I can get hard into this, but I thought I'd get my first impressions posted now to hopefully generate some fresh comments before I can get back on line.

Have a look at the regency vehicles sourebook for TNE if you can, they redid all these vehicles. There are now 3 trepida one with an X gun and VRF Guass gun, and a astrin with a gun (from Archduke Norris who came to the same conclusion as you).

Cheers
Richard

Richard,

I've seen the TNE treatment of the Trepida, but not their version of the Astrin.

Unfortunately, I don't own a copy. Any chance you could extract some of the detail and post it here?

I only remember two versions, one base model and one improved version.

Default Striker version of Trepida

posted here is an old Striker Trepida Version of mine.

Basically same but crew increased, thrust tons improved (along
with speed).

Actually shaved down to 9.5 Dtons including turret.

24mm of Armor all around gives AV of 40 on deck and belly, 44 on moderately sloped sides and rear and AV of 47 on the radically sloped from

use, abuse, deride, ect

Any solid errata out of this yet? That sloped armor idea sounds like a great step... that's definitely something from Striker that's missing in MT!

Not exactly solid yet.

The Trepida redesign linked above may be a source of changes to the one in 101 Vehicles, but Jec10 has already provided you with an update. I'd like to get his thoughts before recommending further changes to the errata entry you posted in v 2.18.

The sloped armor is something I'm working on. I'm not sure yet whether the addition of sloped armor is worth the extra calculations. MT simplified things considerably by eliminating the calculations for thickness and toughness and slope in favor of keeping armor value as a constant and varying weight by armor type. I kind of like the rule to vary armor value by facing presented earlier in the thread. If you look at the redesigned Trepida UCP sheet, you'll see the facing values listed as an option.

When I settle on an errata recommendation, I'll post it in the errata thread. I hope your post will generate more discussion on the topic in the meantime.
