Earth, 6 June 2160 - In response to the disastrous performance of the Armed Forces during the Alien War of 2158-59, the Government has invited companies to compete for contracts to produce new classes of ships and weapons. New designs will be evaluated by a board including scientists and military officers.

Do you want feedback on your design?

Oh, if people want to comment, that is of course ok by me. Everyone here is much more knowledgeable than I am about the game, and if someone is kind enough to take away from their own game time to provide feedback on my inept designs, I am happy to learn.

I make these postings simply because I like to have a bit of RP fun with Aurora. If each of my empires is ultimately going to crash and burn, at least I will try to make it interesting. :grinning_face:

Those missiles are basically useless unless you are using pre TN engines and expect to shoot them at player created ships with the same tech. Any NPR ship including freighters will fly away from them. The flight time is also insanely long, these missiles will launch and then do nothing for 5 days or so. Give them more and boosted engines or don’t bother building them as they are a waste of resources

/////

The Hober Mallow-class fuel harvester was the fuel production workhorse of the early Empire, initially operating in Sol only, but later shifting to the Wolf 359 System to supply the expanding Wolf 359 II colony with fuel. The FH Lathan Devers continues to harvest sorium in Wolf 359, but the FH Hober Mallow was destroyed in the Alien War of 2158-59.

Good overall design. One thing you probably want to add a refuelling system and designate it as a tanker making it easier to get the fuel from the harvester. Otherwise it looks like my fuel harvestes

Notably your fuel harvester is faster than your anti-ship missile…

Launch date: February 2113

Names: Gravitas, Gabela, Gao

/////

The Gravitas class frigate was the Empire’s first warship. Launched by Abadan Shipyard in February 2113, only three were built. It was intended to function as a convoy escort vessel between Sol and Procyon, but is now recognized as a generally weak design. Since the Alien War of 2158-59, these frigates have been confined to system patrol in Procyon.

Antonin, may I suggest you to start to think that every NPR or spoiler you will meet could deploy ships that have high performance? and your designs shall be able to face this possible disadvantage, trying to survive and hopefully win anyway the confrontation? so your design should install the best of the best of the tech you have at that moment.
Otherwise, your ships will succumb to an hostile one. Lossing men, commanders and resources… not the best way to play and win the game, doesn’t it?

I think you should increase the armour of the frigate. IMO, 4 or 5 could be a satisfying trade off for this ship size.
Remove the refuelling system, unless you think to use the ship to refuel other ones too, designating it as a tanker. Otherwise it is useless, and wasted mass and space.
This ship has no passive sensors. So, if the active sensor is off, it is blind. But if your active is on, it will reveal your presence to almost everything in the system.
Try to improve the performance of the fire control, as its tracking speed is very low. This limits the effectiveness of the laser. Also the range should be better.
Start to think to design laser turrets: they allows higher tracking speeds, to be able to engage rather fast enemies.
It’s a trial and error process, but it can be rewarding. :slightly_smiling_face:

I think you have refuelling systems the wrong way around, the tanker needs them. Not the ship being refuelled so remove from Frigate and put on Harvester. Also you have a reactor providing 5.9 power for weapons using 3 . This is a small waste of space as 2.9 of that is wasted.

/////

The Andromeda-class laser beam corvettes were designed and built on an emergency basis following the disaster of the First Alien War. They were regarded as an improvement on the Empire’s previous beam warfare ships, but all 4 of these corvettes were destroyed near Earth when the Alien War flared up again in June 2163. The Argo and the Ashmont did some damage to the alien warships, but because no survivors were rescued and no salvage recovered, details remain unknown.

You are drastically under-armoring your ships. I consider 4 rows of armor a bare minimum, and most of my designs have 7 or more rows of armor. That will give your guns more time to shoot the enemy before they kill you.

Consider establishing a target % of your ship’s tonnage for engines and fuel, weapons (including powerplants and fire controls), and defense (armor, shields once at higher tech level, and ECM). Something like 35%/25%/25% for a beam ship, with the balance being sensors, bridge, eng, etc.

I think you are absolutely correct. My difficulty here is that I have been playing Space Empires IV for more than 20 years, and in that game armor is a component that you manually add to a ship. There are many elements of Aurora that are very strange to me.
