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: And The Worlds of The Expanse (no spoilers)

What is the universe of The Expanse like? What are the cultures and histories of Earth, Mars and the belt? How does gravity work in The Expanse? How does science and technology affect people and relationships? What are the roles of Holden, Miller and Avasarala in the story of The Expanse?

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.

Spaceships: Armaments and External Weapon System Bays

While guided munitions can self correct mid flight, or just after launch, you can shoot them in most directions.

Energy weapons and unguided munitions would have a rather limited arc when embedded in an internal bay, so you can embedded in a rather largish gun box, that's at least ten percent larger due to the rotating machinery, and not countig the extra armouring, which could be greater than that of the default hull.

This means you can fire in any direction, as long as nothing on the superstructure blocks it's line of sight.

This would require at least a thousand tonnes in addition to that used by the external bay, in order to, ah, support the external bay, but all unused tonnage can be used to embed other weapon systems, as per High Guard rules.

Spaceships: Hull, Armour and Corrugated Configuration

Image

... The aircraft's unusual corrugated duralumin metal skin, pioneered by Junkers during World War I, strengthened the whole structure.

Lufthansa's 21st-century airworthy heritage Ju 52/3mg2e (Wk-Nr 5489) in flight, showing the Doppelflügel, "double wing" trailing-edge control surfaces
The Ju 52 had a low cantilever wing, the midsection of which was built into the fuselage, forming its underside.[1] It was formed around four pairs of circular cross-section duralumin spars with a corrugated surface that provided torsional stiffening. A narrow control surface, with its outer section functioning as the aileron, and the inner section functioning as a flap, ran along the whole trailing edge of each wing panel, well separated from it ...


Like planetoids, I suspect laser beams and possibly energy weapons in general have a better bite on this configuration.

Spaceships: Hull, Stealthed and Mass Effect Normandy Class Stealth Frigate - Ship Breakdown

Spacedock breaks down the iconic Normandy Class Stealth Frigate.

https://www.youtube.com/watch?v=K5gOdD2s7ck

The Normandy's IES (internal emission sink) stealth system is her most notable feature. For centuries, it was assumed that starship stealth was impossible. The heat generated by routine shipboard operations is easily detectable against the near absolute zero background temperature of space. The Normandy, however, is able to temporarily "store" this heat in lithium heat sinks deep within the hull.

The IES stealth system has a few limitations: The system doesn't work during FTL flight because this blue-shifts the Normandy's emissions beyond the sinks' ability to store, and even while out of FTL, any visual scan (i.e. looking out of a window) will reveal her. However, this is rare since most ships rely on scanners rather than visual contact and spotting another ship in space is difficult. The Normandy can go to 'silent running' for around 2-3 hours, or drift passively through a system for days before having to vent and give away her position. The stored heat must eventually be radiated, or it will build up to levels capable of cooking the crew alive.


Okay, I have no idea how this is supposed to work, since I would have thought lithium would be used for the batteries. Or maybe, heat recharges batteries.

Simplified version.

It works by having a large slab of lithium that you heat up with the waste heat from your heat management system, The metal gets hotter then melts, then boils, but all the heat stays inside the ship.

Once your metal has reached boiling point you will have to break out the radiators or jettison the metal to dump the heat or you are risking a pressure explosion.

The heat sinks in Attack Vector Tactical work along these principles but use sodium IIRC.

If that's the case, I\d want something cheaper to jettison.

How about letting the hydrogen turn to plasma, and dumping that.

Or better still, expelling it towards some ship currently in your way. Sort of a reverse fusion rocket.

Spaceships: Gerry Anderson’s Firestorm | Exclusive FULL Minisode

The series is set in 2102. Thanks to technological improvements climate change has been brought under control, food and energy are plentiful, and violence has all but disappeared.

But just when people are at their most contented, the problems start… Explosions, sabotage, large-scale thefts of military equipment, kidnapping… the only clue as to the perpetrators is a name – BLACK ORCHID. Earth’s environmental protectors – STORM FORCE – are quickly repurposed into a force to fight this mysterious assailant. Their new operation codename... FIRESTORM.

As clues are uncovered, Black Orchid seems to be an alien contingent. But what are they up to? As Storm Force discover more - including strange telepathic technology - the alien explanation looks increasingly likely. But when Storm Force come face to face with Black Orchid they discover their true origins...

Spaceships: Hulls and How Dangerous is Deep Space Travel to Mars and Beyond ?

NASA has a mission protocol which says that if a Low Earth Orbit mission increases the lifetime risk of the crew getting cancer by more than 3% they won’t go ahead with it but the upcoming mars missions may expose the crews to levels that would be beyond that limit and other hazards, so how dangerous is deep space travel to Mars and beyond.

https://www.youtube.com/watch?v=IyUwSJ5pXS0

That's why the fuel bunkerage is spread around the crew compartments; you could epoxy coat the hull.

What about if the hull is a soft, inflatable design? Honest question. This science is way beyond me. I just saw the concept today at Kennedy Space Center. Had no idea NASA was looking at softsided vessels, but it makes sense if they can make it work.

My contrbution for today:
The bad:Chaperoning 4th graders around Kennedy Space Center.
The Good: got to see the Falcon 9 launch from the bus while we were leaving. Good stuff.

I always thought the fuel bladder, possibly stretched over a metal skeletal framework or preshaped internal configuration, could be an interesting hull material alternative.

You can't bounce light off it, but it shines of itself (primarily IR unless very hot). No problem seeing it with an IR sensor.
