T2 Kennel vs T3 Kennel cost efficient

[Kamui]

Which one is the most cost efficient? Is it better to build 2 T2 kennel or upgrade the current one to T3? Didn't find any info in the wiki about the T3, only T2.

Engineers 40 UEF T2 Engineering Station Drone: C-D2 "Rover-2" 26.25 (35) for Upgraded T3 Kennel

Engineers 20 UEF T2 Engineering Station Drone: C-D2 "Rover-2" 27.5 (36.6) for T2 Kennel

There are 2 T2 Kennel? I'm confused, somebody with insight on this?

I believe they work out roughly the same, the difference is a t3 takes up less room. So instead of just 1 engineer you have 2,

I always upgrade to level 3 as you simply get more engineers so while 2x1 are just as fast as a single 1x2, 2x2 are even faster. (as you have 4 engineers instead of 2).

Ok the parenthesis numbers were for different game versions, i got the answer to my question. T3 Kennel is cheaper per mass and higher build rate, which makes it a waste to not upgrade it to T3 right away.

there is also larger operational radius on the upgraded.
Bugged in steam/vanilla, you can manually assign them to assist something outside the radius.
There is a bunch of really unfair things you can do that way, since they can not be targetted by enemies, unlike the construction bot upgrades on the ACU/SCU that can be targetted and cost resources to replace.

The Kennel offers more than just mere construction speed per mass: a unique unit. The only flying engineer in the game. Can't construct structures, yet do everything else an engineer can. Can't be attacked by ground units but by anything capable of attacking air units. Gets replaced for free in case of destruction at its Kennel after some delay. Unlimited travel distance. Kennels can be used in addition to other engineering units to reclaim the wrecks of a battlefield to get it done faster and force the enemy to bring anti ground and anti air units to stop you. Anything that lacks anti air support can be reclaimed or captured with Kennels. They're also better at assisting anything due to far less formation / collision issues than regular engineers and can be kept behind units on the battlfield that you want to assist / repair. Where a Kennel is built doesn't really matter as the drone can move anywhere, unlike the repair stations of other factions.

Edit: To answer the core question: Since upgrading a Kennel is cheaper than building one and the result is the same (you get 1 drone) upgrading is the better choice, taking the data from the linked wiki. Ingame I'd have to check the base game and FAF version of it, which I won't do. The build time is an issue though, being almost twice as much on the upgrade (2000 for upgrading to T3, 1100 for constructing another T2 Kennel).

I usually build them close to my T2/T3 factories where most of my T1 Engineers are so they help build it faster.

Yep I normally put them on two or three sides of a factory (if 2 sides, I end up making them 2 deep too), they help churn out the units super fast, also means I do not need to micromanage engineers, in fact once I get the tier higher engineers, I tend to recycle the lower tiers.

I also put quite a few on the shoreline where they are close to a navel factory to help build units too, again saves micromanaging engineers.
