Spaceships: The Truth about Hydrogen

https://www.youtube.com/watch?v=f7MzFfuNOtY

More than one way to skin a cat, or power a ship.

I'd say that solar panelling would provide the transformative energy.

You might not want to light off a fusion reactor, especially if you're in silent running. And you have all that hydrogen tanked away anyway.
 
Spaceships: A new way to remove CO2 from the atmosphere | Jennifer Wilcox

Our planet has a carbon problem -- if we don't start removing carbon dioxide from the atmosphere, we'll grow hotter, faster. Chemical engineer Jennifer Wilcox previews some amazing technology to scrub carbon from the air, using chemical reactions that capture and reuse CO2 in much the same way trees do ... but at a vast scale. This detailed talk reviews both the promise and the pitfalls.

Neither energy nor heat would appear to be difficult to obtain on our spaceships.

A synthetic forest five hundred times more effective than a biosphere?
 
Spaceships/stations: What's the Most Realistic Artificial Gravity in Sci-Fi? | Space Time | PBS Digital Studios

2001: A Space Odyssey introduced a lot of people to the idea of rotation based artificial gravity, but in sci-fi, it’s far from the only one to implement the idea! Babylon 5, Halo, and Ringworld also used rotation-based artificial gravity in their stores, but, being an astrophysicist I had to ask, WHO DOES IT BEST? And more importantly, is artificial gravity in space possible? And I’m talking outside of your artificial gravity in Kerbal Space Program (but we may get there).

Spaceships: Engineering and Introducing Reaction Wheels

You hear about them in space news a lot, but what do reaction wheels actually do?

Scientists May Have Figured Out Why So Many Spacecraft Were Failing

In the last 20 years it's been surprisingly common for space probes to end missions early because reaction wheels have failed, moreover there's been a large number of failures associated with a specific supplier - Ithaco. A NASA spin off which developed low cost reaction wheel systems that helped bring the cost down for many space missions.
A new study offers some clues as to what might have been going on and why solar weather might be able to damage mechanical systems.

Spaceships: Engineering and Ion Drives And Electric Propulsion | Answers With Joe

Ion drives are a type of propulsion that provides a very small amount of force over a very long period of time, giving it the ability to build up to incredibly fast speeds.

I'm thinking more high velocity slingshot, and using ion drives to brake.

New energy source.

Also, why Solomani ships have ship cats.

And why the Vilani lost.

Or a large honeycombed asteroid dragged into closer orbit.

In either case, mono-acceleration drives are viable.
 
Spaceships: Fighter Jockeying and How to Dogfight in Jets: Air Combat Maneuvering: Flight Tactics 1960 USAF Training Film

Air combat manoeuvring (also spelled: air combat maneuvering, or ACM) is the art of manoeuvring a combat aircraft in order to attain a position from which an attack can be made on another aircraft. It relies on offensive and defensive basic fighter manoeuvring (BFM) in order to gain an advantage over an aerial opponent...

There are five main things which a pilot must remain conscious of when contemplating an aerial engagement, of which, getting and keeping sight is the most important. In Southeast Asia, over 85% of all kills are attributed to the attacker spotting and shooting the defender without ever being seen. Structural limitations of both the attacking and defending fighters must be taken into account, such as thrust-to-weight ratio, wing loading, and the "corner speed" (the maximum/minimum speed at which the aircraft can attain the best turning performance). Variable limitations must also be considered, such as turn radius, turn rate, and the specific energy of the aircraft. Position of aircraft must quickly be assessed, including direction, angle off tail (the angle between flight paths),[7] and closing speed. Also, the pilot must be aware of his wingman’s position, and maintain good communication.

A pilot in combat attempts to conserve his aircraft’s energy through carefully timed and executed manoeuvres. By using such manoeuvres, a pilot will often make trade offs between the fighter’s potential energy (altitude), and kinetic energy (airspeed), to maintain the energy-to-weight ratio of the aircraft, or the "specific energy".[6] A manoeuvre such as the "low yo-yo" trades altitude for airspeed to gain closure on an enemy, and to decrease turn radius. The opposite manoeuvre, a "high yo-yo", trades speed for height, literally storing energy in "the altitude bank", which allows a fast moving attacker to slow his closing speed.

An attacker is confronted with three possible ways to pursue an enemy, all of which are vital during chase. "Lag pursuit" happens in a turn when the nose of the attacker’s aircraft points behind an enemy’s tail. Lag pursuit allows an attacker to increase or maintain range without overshooting. "Lead pursuit" in a turn occurs when the nose of the attacking aircraft points ahead of the enemy. Lead pursuit is used to decrease the distance between aircraft, and during gun attacks where the cannons must be aimed, not at where the defender is, but where he will be when the bullets get there. "Pure pursuit" happens when the nose of the attacker points directly at the defender. Pure pursuit is when most missiles will be fired, and is the hardest position to maintain. These are known as pursuit curves...

When one craft is hors de combat, you can always slip back to vic formation.
 
Doesn't have any bearing on how combat in space works:
no atmosphere - so no control surface maneuvering, all you have is thrust and Sir Isaac
line of sight to several light seconds with nothing to hide you
computer controlled weapon systems with reaction times way above what a human pilot can achieve
 
Spaceships: Fighter Jockeying and How to Dogfight in Space

No longer the worst fighter, by BoB!
 
And they repeatedly say in the video that it is complete bollocks to think you can actually dogfight in space. It is cinematic science fantasy.
 
No, dog fighting is simply the point where velocity trumps range.

In space, you end up with more options in how you can apply velocity to reduce the window of time the opponent has to react with.
 
That's what computers are for.

My personal instinct is just to unload a barrage of missiles against any fighter swarm, a gift that potentially can give on giving.
 
My preferred model is the cloud.

Two fleets close to just outside weapon range and launch fighters, drones and missiles, with the odd heavily armoured and PD equipped escort class. This cloud of fun moves to engage, meanwhile the enemy has done the same.

The two clouds duke it out - any ordnance that gets through will face the guns, counter missiles, screens etc of the capitals that have been launching the cloud.

If your cloud can penetrate the enemy's, or better yet completely wipe out their cloud you can then close with the capitals.
 
The new firmpoint rules threw the conventional tactics out the window.

I thought about it, and came up with a fusion of Cold War and Pacific War doctrine: use fleet defenders to snipe enemy fighters and drones at long range, and behind them well armoured medium fighters to close with the survivors.

Spaceships: Fighter Jockeying and Why Mixed Fighter Squadrons Are a Bad Idea

Spacedock lays out some thoughts on mixed fighter squadrons.

https://www.youtube.com/watch?v=NC7bHxwzfS0


I remember Wing Commander; what I found appealing was that the wing/squadron/group had a wide variety of fighters, bombers and fighter-bombers to choose from that was most suitable for a particular type of mission, though while it's not an issue in Traveller, most organizations, civilian or military, like their pilots to be very familiar with one type of craft at any one time, which cuts down on mistakes and training costs.

And then, at least on a carrier, and especially in the Traveller context, space is at a premium, besides wanting to simplify the logistics tail.
