We are now within one tech of being able to design Tugs. We already have all the required research and design work done for Orbital Fuel Stations, Orbital Mining Stations and Orbital Terraforming Stations; hence our need for Tugs to move them into position.
We are also within one tech of designing our first interstellar space ship... a Scout (both Geo- and Grav- capable).
Regarding Laser Fighters: It sounds interesting, agreed. I've always wanted to run a Gun-based campaign instead of always using missiles. But I've always been deterred by the steep requirements of a Laser-based fleet. It's true that Fighters could make use of Lasers decades earlier than Destroyers or Cruisers could.
The reason I always go for a Missile-armed main fleet is simple: far fewer techs are required, and your Navy can become combat-effective decades earlier.
A Laser-based Navy will need to close to point-blank range before it can even open fire. The definition of "point blank range" will of course change with our tech level, but early in the game it might be only 20,000 km. An early-game Missile-armed Navy can open fire at about 1000x that range (20 million km). Even in the late game, when our tech level is topping out, we would need to close to 1,500,000 km or so to do any damage at all, and perhaps to 750,000 km to fire effectively. A Missile-based Navy at that late stage of the game could fire accurate fleet salvos at targets more than a billion km away.
Since a Laser-based Navy must close to point blank range, it must be able to chase down and overtake the opposing fleet, and must do so before you run out of fuel. This required a sizable edge in speed, and lots of fuel tankage as well. It also requires that your ships be able to survive everything the enemy can throw at you WHILE you are chasing him down. You'll need pretty good Armor, Shields and/or Point Defense, in addition to high speed and long fuel endurance.
There are just too many constraints on the design for a Laser-equipped main fleet to be practical before you've tech-ed up to mid-game levels.
I've always wanted one, even so.
But Fighters are another matter. They are attrition weapons anyway, so "surviving everything the enemy can throw at you" isn't really relevant. "Chasing the enemy down" (the other main requirement) is also much less of an issue, since Fighters are DESIGNED to be as fast as practical anyway. Even the short range of Laser weapons is not quite as great a handicap for Fighters, since even when armed with Missiles they rarely fire from maximum range.
A Laser-armed Fighter force would be possible much sooner than a Laser-armed main fleet.
Dibs on being the senior staff scientist this time around!
Any favorite field of research? So far I've been giving most of the labs to Power and Propulsion, but we've pretty well turned the corner on that, and we're going to start ramping up our weapon and sensor tech.
We have installed the 2.1.1 patch, by the way.
