Watching it from wrong station : Bed. Which became a mix between the all station and the feel safe station. The main system is shutting down, I'll try to reboot.

Spaceships: Armaments and Swedish Navy Submarines Have A Unique Secret Weapon

H I Sutton

Thanks to trials with the U.S. Navy, Sweden’s submarines are famous for being stealthy. This is largely due to their Air-Independent Power (AIP), which allows them to stay submerged for much longer. It is not unique, however, as other countries now operate AIP submarines.

But Swedish Navy submarines have another capability that is unique. As well as regular torpedoes, they carry special lightweight ones. And this is where it gets secretive: they can launch two at the same time from a single tube.

The Gotland Class submarine has two torpedo tubes dedicated to lightweight torpedoes. Each tube can ... [+] H I SUTTON (INSERT SWEDISH ARMED FORCES)
That Swedish submarines use lightweight torpedoes is well documented. The double-tap capability is not. It is known about in some corners of the defense community, but like many topics in underwater warfare it is talked about in hushed tones. Slowly word of this capability has crept out, particularly in Sweden, but it is still virtually unknown. And some details of the capability are still secret.

The weapons used are smaller than regular torpedoes but larger than most other ‘lightweight’ ones. They are optimized to kill enemy submarines, although the latest models can also be used against small warships and even enemy torpedoes.

Unusually they are wire-guided, a feature which is normally only found on larger torpedoes. This allows the submarine to guide them all the way to the target. If the wire breaks, or is cut, then the torpedo goes into fire-and-forget mode using its own sonar. Wire-guidance has been found to be more reliable than fire-and-forget weapons in the confined and crowded Baltic. The torpedoes can be guided around an island to hit a target on the other side.

Two of these smaller torpedoes can be loaded into a single torpedo tube, one behind the other. One or both can then be launched. So the effective number of torpedo tubes is doubled. In practice Swedish submarines are equipped with a mix of 21” (533mm) torpedo tubes for ‘full size’ heavyweight torpedoes and 15.75” (400mm) tubes for the special lightweight torpedoes.

This mixed load-out allows the current Gotland Class submarines to shoot up to 8 torpedoes at once despite only having 6 torpedo tubes. Four would be heavyweight torpedoes, each in its own tube, and four would be lightweight ones in double-loaded tubes. The earlier Näcken Class, which had 8 torpedo tubes, could launch 10 torpedoes at a time (6 heavyweight, 4 lightweight).

Double tap is certainly viable for sandcasting; missiles and torpedoes, you'd have to assume a cold launch.

Inspiration: Necromunda: Underhive Wars - Teaser Trailer

Necromunda: Underhive Wars is the first video game adaptation of the Games Workshop tabletop game, with a unique setting and perspective on the Warhammer 40,000 universe, which saw a new version launch to critical success late 2017. Created by Rogue Factor, developers of Mordheim: City of the Damned, Necromunda: Underhive Wars blends fast-paced tactical combat with RPG elements and deep unit customization, coming to PlayStation 4, Xbox One and PC. Step into the twisted tunnels and rusted corridors of the Underhive in a new teaser trailer, seeing life from the view of a hardened Escher gang member.

The turn-based tactical gameplay pits you against rival gangs in brutal gunfights, taking place in huge, vertical environments. Necromunda is a planet covered in poisonous ash wastes, forcing its population to live in Hive Cities, massive man-made structures built up over thousands of years to serve just one purpose: provide to the Imperium. In Hive Primus, the rich and noble live above the clouds in the Spire while the poorest and worst-off live in a massive and forgotten subterranean metropolis, the Underhive, where criminals fight in a perpetual gang war for control.

Command one of Necromunda’s iconic gangs, embracing anarchy, violence and death in an endless war for control to dominate this hellish place. Pick between the Eschers, an all-female gang who have made their name through selling drugs and chemicals throughout the Underhive, or the Goliaths, hulking warriors worshipping physicality and using strength-enhancing drugs to dominate in battle. Other gangs will be unveiled in the coming months.

Compose your gang carefully, based on the style of warfare you want to wage. Every fighter is highly customisable in loadout and appearance, and has access to a career which unlocks further skills, traits, weapons, and visual elements. Battle in the vertical environments of the Underhive, use raised walkways to push a high ground advantage, set traps for unwitting victims, and ambush your foes to force them into bloody melee engagements. With each battle won, your gang members grow in power, earning more powerful skills and loot, but beware! Even victories will result in casualties - deaths and injuries are permanent, and you’ll need to live with the consequences of every battle.

For an even deeper challenge, Conquest Mode offers an endless campaign featuring 4X mechanics between the turn-based battles. Fight over key territory to take complete control and prove your gang is the most fearsome on Necromunda! Then bring your unique gangs online, challenging other players in competitive multiplayer, and claim the Underhive for yourself!

Can you freeze hydrogen? The temperature differential could be quite substantial.


If it's ideal for a spaceship, depends on where the two mediums (the hot one and the cold one) would be situated. Inside a spaceship it's usually relatively warm, because of the excess heat of the crew and equipment, but there is really no good "cold" medium available. Outside the spaceship lies, well, space, but this medium is so evacuated that it's more defined by the absence of a medium than being a medium capable of good heat transfer.

Of course, you could cool down hydrogen and use the temperature differential between the cold hydrogen and the rest of the ship. But that would a) cost a lot of energy - which would have to be provided by outside means (space station or downport likely) and b) you would loose most of your temperature differential when using the j-drive. That is, if a j-drive could work on very cold hydrogen, which I doubt since usual tanks seem to store it at or near room temperature.

I think, this would in total just be a very inefficent drive, which could probably only work on installations that use up the stored and cooled hydrogen only very slowly and either don't have large power needs or can devote a lot of space to hydrogen storage. An emergency power unit for a starport would be such a candidate.

Traveller hydrogen fuel is generally assumed to be stored as liquid hydrogen (LHyd), by necessity frozen to at least 33 K (≈ -240 °C ≈ -400 °F).

While I doubt it would be a viable replacement for a fusion reactor, in the outer system there might be an economic case for it.

1. No life support

2. Two days rations

3. The problem with this supposed canonical military doctrine, is that it would be more believable if Imperial capital ships carried hundreds of TIE Fighters, where a couple of dozen would be an insignificant part of the operating cost, paling besides the time and effort to train these pilots, and then sending out replacement craft and crew to a far flung fleet.
